VESTRE JAKOBSELV: The president of Norges Kystfiskarlag, the Coastal Fishermen's Association, is more concerned with the effects of salmon farming on wild fish populations than he is with the new quota recommendations.
Arne Pedersen is not too concerned about the new quota recommendations for cod and haddock.  It isn't the quantity of fish that worries him: it's their health.
"This is not natural, this is poison," Pedersen said, sawing open a frozen haddock to expose the contents of its stomach. 
The stomach is filled with a brown, fibrous substance that resembles feed pellets, such as those used in the salmon farms near where Pedersen said he caught the fish.  He produces another frozen haddock, saws it open as well, and the contents of the stomach are the same.
As president of Norges Kystfiskarlag, the Norwegian Coastal Fishermen's Association, Pedersen represents more than 1,000 fishermen along the coast of Norway from his home in Vestre Jakobselv, in eastern Finnmark.  Part and parcel to protecting the livelihoods of coastal fishermen, he said, is to protect the health of the fisheries they rely on.
But Pedersen said that he has had no response from authorities when he has brought his complaints to bear.  He suspects it has to do with the enormous economic influence of the salmon farming industry in Norway: salmon farming comprises 80 percent of the Norwegian aquaculture industry.  More than 95 percent of Norway's aquaculture production is exported, destined for more than 130 countries.
"There's big money in salmon farms, and they do not speak about this conflict with the coastal fishermen in the areas where they farm," Pedersen said.  "They have a big troop of lobbyists, national and international."
The controversy surrounding the effects of salmon farming on the environment is not a new one.  A vast amount of research has been conducted on the issue, which in recent years has reached a national scale in countries such as Chile, Canada, and the United States.  In Norway and elsewhere, cited impacts include a decrease in wild salmon populations due to the influence of escaped farmed salmon, and the spread of deadly sea lice ("lakselus", in Norwegian) and diseases throughout local wild fish populations. 
Further down the coast, researchers from the Norwegian Institute of Nature Studies and the Institute for Marine Research found in a 2010 study that wild fish near salmon farms had high concentrations of organohalogenated contaminants (OCs) in their systems –chemicals such as polychlorinated biphenyls (PCBs) so toxic that their production was banned by the Stockholm Convention on Persistent Organic Pollutants; and polybrominated diphenyl ethers, a type of flame retardant known as PBDEs.  A total of 45 percent of the fish nearby salmon farms were found to have feed pellets in their stomachs.  The pellets fall through the salmon farm pens and accumulate on the sea floor, and are then consumed by wild fish in the vicinity.  The control fish in the study were found to have no salmon pellets in their system, and up to 50 percent less OCs and PBDEs than the fish nearby salmon farms.
Although salmon farming companies and feed pellet producers tend not to disclose the precise contents of salmon feed pellets, scientists and advocates report that most pellets in the global salmon farming industry contain chemicals such as those indicated in the study, among others.
Pedersen is unaware of any studies that have been conducted within the fjords of Vestre Jakobselv and the surrounding area, but he is eager to see definitive research on what the effects of the chemicals from salmon feed pellets might be on the wild fish.  He said that he has strong suspicions that for wild fish nearby the salmon pens, the chemicals are disrupting their reproduction cycles.
Indeed, the 2010 study recommends further research into this very issue.  But Pedersen is not hopeful this will happen any time soon in his region.
"At this moment, the fishermen catching wild fish, we are on the defensive," he said.  "But in the long term, we have to stay focused on this issue." 
What the Black-Legged Kittiwake can teach us about mercury A study showing that high levels of mercury might prevent a Svalbard bird from breeding could have rippling implications for other large mammals, including humans, that live in the mercury-rich Arctic.
Spilled oil covers tundra rivers Environmentalists say that a state of emergency must be declared after at least 500 tons of oil spilled into local rivers from an oil facility in the Komi Republic.

Special Permits for Oyster Farmers Hit by Virus

 

New Zealand – Special permits can now be issued to some oyster farmers whose businesses have been affected by the oyster herpes virus to gather wild (feral) Pacific oysters, which will come as a great relief to the local oyster industry.

 

Mike Sabin, MP for Northland commented: “I have had a number of meetings with Northland oyster farmers over the past 18 months and have a great deal of empathy for their plight, with this virus devastating their spawning stock and putting the industry on its knees, so this decision will be a real boost for local farmers.“ “Famers raised the question with me of harvesting feral oysters as a potential means for them to remain viable while solutions to the virus were being developed, something I talked over with the Minister and officials. “As it currently stands, oyster farmers are only able to gather feral oysters if they have a commercial fishing permit, something that they explained to me wasn’t a workable fit for their scenario and wasn’t viable given their difficult financial situation.

 

“I am pleased to announce that the Minister for Primary Industries (MPI), Nathan Guy has approved a new special purpose permit under section 97(1)(c) of the Fisheries Act 1996 enabling MPI to issue special permits to oyster farmers to collect feral oysters and transfer them onto their marine farms, for later re-harvest and sale," said Mr Sabin.

 

The decision follows consultation with Maori and other affected stakeholders, Mr Sabin saying the permits will be valid for three years to allow the oyster industry to recover from the impacts of the virus and the permit would still be subject to food safety requirements. In approving the special permit purpose, Minister Guy acknowledged the unusual and special circumstances of this particular situation, providing a cost effective mechanism for farmers to recover while they try to rebuild their industry … … .

In an article published last Thursday, 13th June, we made it public that the Salmon & Trout Association Scotland had revealed that sea-bed monitoring under Scottish salmon farms reveals breaches of Environmental Quality Standards at nearly one in five fish farms for residues of sea-lice treatments toxic to lobster, crabs and prawns.

In an article published last Thursday, 13th June, we made it public that the Salmon & Trout Association Scotland had revealed that sea-bed monitoring under Scottish salmon farms reveals breaches of Environmental Quality Standards at nearly one in five fish farms for residues of sea-lice treatments toxic to lobster, crabs and prawns.
Information obtained under Freedom of Information by the Salmon & Trout Association Scotland (S&TAS) from the Scottish Environment Protection Agency (SEPA) shows that toxic pollution is carrying on unabated despite the requirement to meet set environmental protection standards.
We said – and hold – that SEPA has a case to answer for the light touch regulation it deploys in this context.
SEPA statement
A spokesperson for the Scottish Environment Protection Agency (SEPA) says: 'We refute these claims as they are based on figures which are inaccurate. Although evidence of sites exceeding our environmental standards is of interest to SEPA, and may lead to further discussion or investigation, the low level of the breaches, and the fact that almost 90% of sites are within our standards, indicates that SEPA is very much in control of the use of Slice.
'We are concerned that the repeated misinterpretation of raw aquaculture data is painting a more negative picture than actually exists. Supplying the data and then having to correct such inaccuracies is particularly resource-intensive and uses up a significant amount of time which would be better spent resolving genuine issues.'
Information which SEPA says clarifies the data:
As is the risk with reports such as this, the presentation of data is somewhat misleading.
SEPA supplied data from 146 sets of sediment sampling and analysis. Some of these were duplicates from individual sites and, therefore, the data only represents results from 133 sites.
There also appears to be some misunderstanding in the S&TA's interpretation of our standards. SEPA accepts that an area around a fish farm, known as the footprint, will exhibit some degree of impact from the farm's operations. SEPA sets a standard for the maximum concentration of 'Slice' residues that must be met at the edge of the footprint of the farm – usually 100m from the cages.
This is known as our 'far field' standard, or Environmental Quality Standard (EQS), and is designed to protect the environment and other important commercial species such as crabs and lobsters. SEPA also seeks to measure concentrations of residues at the edge of the cages, but this is used for other purposes, such as determining monitoring strategies, as opposed to the protection of the environment. The far field EQS has a good deal of precaution built-in, meaning that environmental effects from minor exceedances are highly improbable.
Of the 133 sites, only 15 (11.3%) showed sediment residues of Slice in excess of our far field standard.
The degree of exceedance is also important before drawing conclusions on the significance of results or potential environmental effects. The analyses are carried out at 10ths of a part per billion. Therefore, there has to be a reasonable margin of error in the results. For this reason, SEPA is unlikely to take substantive action against sites or analyses displaying values slightly above our EQS, whereas significant breaches are more likely to result in action being taken. For example, values of 10x our standards would be considered serious and lead to the site being downgraded in our assessment scheme and could lead to licence variations to reduce impacts. Values of 2-10x our standard would be recognised as likely to be within, or close, to the margin of error in the analysis and would require less significant action.
For the 15 sites showing breaches of standards, the scale of exceedances are as follows:
7 exceeded by less than 2x
8 exceeded by 2 – 5.22x
While the higher values could certainly lead to further scrutiny by SEPA, they are not results that would precipitate immediate, serious action by the Agency.
Salmon & Trout Association Scotland response
This is a statement from Guy Linley-Adams, solicitor to the Salmon & Trout Association Scotland in response to the SEPA claims.
'The S&TAS recognised that there are duplicate samples for a handful of the farms, but since only one of the farms reported as exceeding EQS or trigger values was a duplicate (Ardgour), the percentage of farms reported as 'breaching' in the S&TAS press release should, if we accept SEPA's arguments,  be higher not lower than stated. But no doubt SEPA would have criticised us for failing to take into account the duplicates if we had not done so.
'SEPA appears to be suggesting that a breach of the inner field trigger (ie the sea bed sampled at the cages) is not something that needs to concern anyone too much – but, as SEPA has previously acknowledged, this inner field figure is set to protect sediment re-worker fauna, mainly those few species of organic pollution-tolerant worms that consume the organic detritus that accumulates under a fishfarm, without which the sea-bed would be even more grossly polluted by feed and faeces under the cages than it is already under most farms.
'As to EQSs, all EQSs are set at a precautionary level for a valid scientific reason. Napier University's Review for the Scottish Executive (2002) Review And Synthesis Of The Environmental Impacts Of Aquaculture stated of emamectin benzoate that "there is relatively little information available on the toxicity of this chemical to marine benthic invertebrates in particular, and little is known about the potential long-term impacts of this chemical on the marine environment." The EQS was set in 1999.
'This is why there is a safety margin in the EQS, not so SEPA can use it to justify downplaying breaches of 2x or 3x the EQS. An EQS has a safety margin built in for a reason – usually that the ecotoxicological basis of the EQS itself is not always that certain when the EQS is first set by the scientists – it is not something that should be routinely traded upon, permitting regular exceedances  because it is somehow considered in some way 'probably alright' to do so.
'As to margins of error in the values determined, there may well be margins of error, as with all sample analyses of residues, but SEPA seem happy to use these figures in their own reports (such as the annual Results of Screening Surveys reports, available online from SEPA) and particularly where the figures (presumably with such margins of error in them) are below the EQS, SEPA is content to use them to suggest that everything is satisfactory at a particular site.
'If the errors in sampling emamectin in sediments are that bad, then SEPA should assume a certain number of the lower values it records or receives, that are  just below the EQS are, in fact, 'false negatives' and generally be a little more precautionary in their view of what the data shows.
'As to the accusation of repeated misinterpretation, S&TAS refutes that completely  and would suggest that perhaps SEPA should itself publish an analysis of the chemical residue data it receives from fish-farmers, and not just its very small audit sampling programme, rather than the S&TAS and the public having to rely on making freedom of information requests.
'Regulation 4 of the Environmental Information (Scotland) Regulations 2004 places a duty on all Scottish public authorities (SEPA included) in relation to the 'active dissemination of environmental information'. Specifically, Regulation 4 (1) requires SEPA to "… take reasonable steps to organise and keep up to date the environmental information, relevant to its functions, which it holds and at least the types of information listed in paragraph (2), with a view to the active and systematic dissemination of that information to the public …….". Paragraph (2) of Regulation 4 gives the types of information referred to in paragraph (1) and includes "(e) data or summaries of data derived from the monitoring of activities that affect or are likely to affect the environment". That would seem to cover this fish farmer-reported data.'
Mr Linley-Adams suggestion '…that perhaps SEPA should itself publish an analysis of the chemical residue data it receives from fish-farmers' is the simple and obvious solution to this dispute.
The publication of this data would make the picture perfectly clear and would authoritatively inform the concerned public of the extent of the sea bed polution from sea lice chemical drenching with Slice.
It is in everyone's interests that this should be done without delay, not least in the interests of the salmon farms anxious to restore their credibility in a situation  where SEPA insists that there is no pollution worthy of variation of licence to a farm.

Texas—A Potential Cure for EMS

 

On June 13, 2013, I chatted with Maurice Kemp, Ph.D., chief technical officer of Mionix Corporation, a technology company with products that help reduce food contaminating pathogens and control bacterial diseases that may infect animals.  Mionix markets a product called “Vitoxal®”, a blend of sodium/calcium aluminosilicate mixed with acidified calcium sulfate that has the potential for stopping early mortality syndrome (EMS).  Recent research in Malaysia has shown that high pH levels trigger EMS outbreaks in shrimp ponds.  Vitoxal, blended with feed and consumed by shrimp contains acidic calcium sullfate (approved by the FDA and USDA), lowers the pH in the gut of shrimp and prevents bacteria like Vibrio parahaemolyticus from replicating and spreading.

 

 

In general, acidification of the gastrointestinal tract facilitates growth of gram positive bacteria, i.e., bacteria that competitively exclude, secrete products that suppress or inhibit development of microbial pathogens (e.g. Vibrio spp. and Pseudomonas spp.  Gram negative bacteria, such as Vibrio spp. and Pseudomonas spp. are more sensitive to pH changes than gram-positive bacteria.

 

Shrimp News: Do you think Vitoxal will be effective against EMS?

 

Maurice Kemp: Yes, but it depends on when the bacteria enters the shrimp’s body.  If it enters prior to adding Vitoxal to the diet, it probably will not stop the disease, but if the bacteria enters the shrimp’s body after it has consumed Vitoxal, it is very likely that it will prevent Vibrio parahaemolyticus from infecting the shrimp.

 

Shrimp News: EMS/AHPNS is caused by a bacteria (Vibrio parahaemolyticus)that’s infected with a virus (a phage) and transmitted orally.  Together, they colonize the shrimp’s gastrointestinal tract and cross the gut membrane thereby establishing a systemic infection.  Typically, a toxin is then produced by the phage coded gene that is secreted, causing tissue destruction and dysfunction of the hepatopancreas, a multi-function organ distinct from the gut.

 

 Shrimp News: When the Vibrio populations are reduced does the phage also suffer?

 

Maurice Kemp: Yes, in fact the phage’s DNA becomes part of the Vibrio’s DNA, so they go down together.

 

Shrimp News: Have you tested the product on shrimp?

 

Maurice Kemp: Yes, but not to treat EMS.  Vitoxal has been used in Ecuador to control Vibrios in general early in the growout cycle and late in the growout cycle.  It eliminates the Vibrios early in the growth cycle and if stress causes them to reappear, Vitoxal will bring them under control again.  We’re not talking about wiping out the Vibrios like you would with an antibiotic, we’re talking about controlling them, so that the shrimp continue to grow normally.

 

Shrimp News: Is it the low pH that stops the growth of the Vibrio in the gut of the shrimp.

 

Maurice Kemp: Yes, It brings down the pH and stops the replication of the Vibrio.  Normally, the gut of a shrimp has a neutral pH (around 7).  Blended with feed, Vitoxal lowers the pH in the gut to 4–5.  When consumed it likewise lowers the pH to a level the Vibrios can’t tolerate.  In addition, research conducted at the Texas A&M Mariculture Research Center by Dr. Addison Lawrence indicates that Vitoxal changes the surface of the gut wall so that the Vibrios are no longer capable attaching themselves to it, further preventing a systemic infection.  Dr. Lawrence’s studies also clearly indicate that Vitoxal stimulates the shrimp’s primitive immune system, which adds even more protection.  So, in addition to creating an environment where Vibrios can’t reproduce, we’re changing the gut membranes and we’re stimulating the shrimp’s primitive immune system.  Together, these three factors should bring an end to the EMS epidemic.

 

Shrimp News: Are you making any arrangements to test your acidifier on animals that have been exposed to EMS.

 

Maurice Kemp: Yes, we are going to do challenge studies.

 

Shrimp News: How much will it cost to add your acidifier to shrimp feed?

 

Maurice Kemp: It will add less than three percent to the cost of the feed when added at a level of 1%!

ANALYSIS - The key to disease prevention is the maintenance of good fish welfare among the stock according to Dr Sunil Kadri the managing director of Europharma Scotland and Aquaculture Innovation.

Dr Kadri, speaking at a recent Federation of Veterinarians of Europe conference in Brussels said that fish welfare is a very wide term that has implications in other areas of aquaculture management.

ANALYSIS - The key to disease prevention is the maintenance of good fish welfare among the stock according to Dr Sunil Kadri the managing director of Europharma Scotland and Aquaculture Innovation.
Dr Kadri, speaking at a recent Federation of Veterinarians of Europe conference in Brussels said that fish welfare is a very wide term that has implications in other areas of aquaculture management.
And he warned that all too often disease management is seen as the means of managing fish health and is viewed separately from fish welfare. The whole picture of production measures together with disease treatment has to be taken into consideration to ensure full health and welfare.
Dr Kadri said that fish health management has come a long way over the decades and has been greatly improved by preventative measures, which are often used as a standard approach – such as the use of probiotics and vaccines.
However, he added that these measures are not without their problems and should not be used for an excuse for complacency among fish health managers.
He said that preventative measures such as vaccination can have problems with side effects and other issues come into play for maintaining health other than curing and preventing disease.
Many of the measures being used by fish health professionals are just fire fighting and the losses through disease can be severe and have not changed much over 20 years
"Vets react well with diagnostic tools, but it is fire fighting. We need a new paradigm," he said.
He said that the veterinary community in general needs to become more aware of what actually takes place in the aquaculture environment to ensure the total health and welfare of the fish.
The veterinarians need to work with the people on the farms so that they can learn and the farmers can learn, he said.
"Health is a state of complete physical well-being and not merely the absence of disease – it is not about fish coping but performing too," he said.
Dr Kadri said the most important aspect of fish health and welfare is water quality, including monitoring the quantities of carbon dioxide and heavy metals as well as the supply of water and the renewal rates.
Welfare considerations also have to take into account the water support systems such as the oxygen supply, boreholes and reservoirs.
Further welfare issues that impact on fish health are the stresses that the fish are placed under in loading on and off the farm and the stresses in transport and the need to mitigate potential mortality rates, which have an economic effect on the business.
"Effects of stress upon fish health are real and demonstrable," he said.
Other issues of husbandry such as nutritional requirements, the type of feed, nutritional profile, pellet size and feed management also have to be taken into consideration.
He said that common pathogens often have subclinical effects and these need to be managed not only through veterinary intervention but also through husbandry practices.
"Veterinary diagnostic approach often involves 'experts', who have little or no connection with production," he said.
Dr Kadri added that the industry needs to reduce losses to grow sustainably and this requires a paradigm shift in veterinary/health care.
He said there needs to be a move towards greater involvement with production and allowing preventative health/welfare management.

Morton versus the Department of Fisheries and Oceans

 

Both sides likely to quote Cohen report in federal court case


• 12:00 am
1/1
(Provided by SFU Public Affairs and Media Relations) Alexandra Morton is taking Canada's Minister of Fisheries and Oceans and Marine Harvest Canada to court over fish farms.

The community of Echo Bay sits on the west side of Gilford Island, one of a group of islands comprising the Broughton Archipelago near the northern tip of Vancouver Island on B.C.’s Central Coast. In 1984, this remote settlement became the home of biologist Alexandra Morton, originally from the United States, who moved there to study a pod of orca whales living in the area. In the late ’80s, as aquaculture companies began opening up salmon-farming operations in the waters Morton had come to call home, her professional focus shifted from studying orcas to studying the effects these farms were having on the local ecosystem.

Morton had no choice but to shift focus; the orca whales left shortly after the salmon farms arrived. Morton says the whales fled the underwater acoustic devices used to keep seals from preying on farm fish, so she turned her attention to investigating the influences farms were having on wild salmon stocks. Her research has resulted in multiple papers published in peer-reviewed scientific journals, Science among them.

Although the scientific community has not always unanimously agreed with Morton, the byproducts of salmon farms that, in Morton’s opinion, pose threats to wild salmon are manifold — from epidemics of sea-lice that kill juvenile salmon, to escaped Atlantic salmon competing with wild populations. Now, however, Morton is convinced that farmed salmon are spreading harmful diseases to their wild cousins along the coast of B.C. Sufficiently convinced, at least, to take legal action in order to prevent an aquaculture company from putting what she says are lethal-disease-carrying fish into B.C. waters.

Morton, represented by Ecojustice environmental group lawyer Margot Venton, filed a lawsuit on May 7th in a Vancouver Federal Court against both the Minister of Fisheries and Oceans (DFO) and Marine Harvest Canada, a subsidiary of Norwegian aquaculture giant Marine Harvest. The lawsuit contests Marine Harvest’s right, provided under a license issued by DFO, to transfer fish infected with a virus called piscine reovirus (PRV) from land-based hatcheries into open-pen fish farms.

PRV was only recently identified, in 2010, but some studies have fingered it as a potential cause of Heart and Skeletal Muscle Inflammation (HSMI), a disease that has been found to cause up to 20 per cent mortality among diseased fish in Norwegian salmon farms. Morton is concerned that, if it hasn’t already, the presence of PRV in farmed salmon in B.C. could lead to an HSMI outbreak in wild fish.

Morton did not respond to attempts to contact her in time for this publication. However, in a recent press conference held to discuss the lawsuit, she said, “[PRV] started in Norway and it spread rapidly; they’ve been unable to control it. It damages the muscles and the hearts of the fish, to the point where scientists don’t even think they can make it to rivers and if they do, that they might not even be able to swim up the rivers.”

Morton also said that after learning PRV was present in fish originating in Marine Harvest’s Dalrymple Hatchery in Sayward, B.C., “[She] asked [the DFO, the province of B.C. and Marine Harvest], ‘Please don’t put [PRV] in the water. It is too dangerous,’ but they went ahead and did that. It’s on the Fraser sockeye migration route, and it is a serious threat.”

The “Fraser sockeye” are a population of sockeye salmon that enter the Fraser River at its confluence with the Strait of Georgia, just south of Vancouver, before travelling upstream — in some cases as far as 800 km — before spawning. Over 10 million Fraser sockeye were expected to return to the river in 2009, and when only 1.4 million fish showed up, a federal inquiry was held to try and find out why. The inquiry was led by B.C. Supreme Court Justice Bruce Cohen and was dubbed the Cohen Commission.

Morton, who participated in the commission, points to salmon farming as a major factor in the decline of Fraser sockeye stock, but Commissioner Cohen did not confirm this. He concluded that “Data presented during this Inquiry did not show that salmon farms were having a significant negative impact on Fraser River sockeye.” Other scientists involved in the Commission also disagree with Morton’s assessment.

Gary Marty is a veterinary pathologist (specialist in the diagnosis of animal disease) who has been the B.C. Ministry of Agriculture’s fish pathologist since 2004. In an email, Marty pointed out that, contrary to what Morton has said, “Just because PRV was first identified in Europe, that does not mean that PRV originated there.” In other words, PRV may have been present in B.C. salmon all along.

When PRV was first reported in 2010, Marty went through 625 samples archived from B.C. salmon farms in 2009 and 2010. The samples were taken from both healthy fish and fish that had died. He found that roughly 80 per cent of fish across both groups tested positive for PRV, indicating that PRV, although certainly present in farmed fish, didn’t appear to be related to mortality. Additionally, Marty points to a recent study published in the Journal of Fish Diseases led by scientists at the Norwegian Veterinary Institute. The study found no indications of HSMI in wild fish in Norway — despite finding PRV. Marty’s message is straightforward: PRV in farmed salmon does not appear to lead to HSMI in wild salmon. In fact, in Norway, where the disease HSMI was first identified, “authorities place no restrictions on moving PRV-positive fish from freshwater to saltwater if the fish have no associated disease,” wrote Marty. HSMI has never been found in any species of Pacific salmon.

Such arguments may have little bearing where Indigenous sovereignty is recognized however, unless  First Nations groups agree.

In its final report, published in the fall of 2012, the Cohen Commission made it clear that there was no “smoking gun,” no single cause of declining Fraser sockeye. Instead, the report emphasized that the decline was probably a result of a combination of multiple influences throughout the lifecycle of the fish, including aquaculture, but also warming rivers and streams due to climate change, and increased human activity along the Fraser River watershed.

The report called for increased federal funds for implementing a comprehensive approach to wild salmon conservation, carried out under the jurisdiction of the DFO.

The report also notes the “DFO has not yet completed research into the effects of diseases and pathogens from fish farms on Fraser River sockeye,” and that as a result, “significant scientific uncertainty remains around the effect of salmon farms on Fraser River sockeye salmon.” In terms that seem especially prescient in the context of Morton’s lawsuit, the report advocates precaution. “Mitigation measures should not be delayed in the absence of scientific certainty.”

Chief Bob Chamberlin, Vice President of the Union of B.C. Indian Chiefs, also spoke at Morton’s press conference. Referring to the Commission’s findings, he said, “In my mind, there are some very clear recommendations to safeguard wild salmon, and it is now time to do something.”

After the Fraser sockeye numbers in 2009 capped a decline spanning almost a decade, the 2010 return came in as the highest since 1913, at 29 million fish.

Shrimp Farmers Unite to Fight White Spot in East Africa

Date: 
12 Jun 2013

AFRICA - Work on reducing the risk of white spot syndrome virus (WSSV) at shrimp farms in East Africa through improved management and policy is progressing, thanks, in part, to a Responsible Aquaculture Foundation (RAF) case study conducted in mid-May.

The case study, the third such project administered by RAF, dealt with a WWSV outbreak at shrimp farms in Mozambique and Madagascar.

AFRICA - Work on reducing the risk of white spot syndrome virus (WSSV) at shrimp farms in East Africa through improved management and policy is progressing, thanks, in part, to a Responsible Aquaculture Foundation (RAF) case study conducted in mid-May.
The case study, the third such project administered by RAF, dealt with a WWSV outbreak at shrimp farms in Mozambique and Madagascar. A team of aquaculture professionals and academics traveled to East Africa to meet with farmers and other stakeholders to review the chronology and impact of the WSSV outbreak and discuss strategies to control the disease.
The team consisted of George Chamberlain (coordinator), Donald Lightner (shrimp pathologist), Noriaki Akazawa (Asian shrimp farm manager), Marcos Villarreal (Central American shrimp farm manager), Richard Towner (geneticist), Peter van Wyk (financial analyst) and Adolfo Alvial (public-private partnerships).
While the remote location of each farm forces farmers to be independent and self sufficient, the WSSV outbreak has introduced the need for increased cooperation in both the public and private sectors.
After much discussion, the stakeholders agreed on four areas of common interest: surveillance of WSSV prevalence in a wild crustaceans plan, biosecurity measures at the farm level, development of specific pathogen free (SPF) WSSV-resistant postlarvae, and regional cooperation among national agencies and producer associations. These four areas of common interest were agreed upon at a concluding workshop in Antananarivo, Madagascar, on May 21 to 22.
Their inspirational spirit of cooperation was reflected in an African proverb, "If you want to go fast, go alone. If you want to go far, go together," said Mr Chamberlain, president of the Global Aquaculture Alliance (GAA).
The details of this RAF case study are outlined in an article written by Chamberlain in the upcoming July-August issue of the Global Aquaculture Advocate, GAA's bimonthly magazine. 
Aquaculture growth opportunities in Africa are among the topics that will be addressed at GAA's GOAL 2013 conference in Paris, France, from October 7 to 10.

Rumors of EMS Are False

 

Dr. Donald Lightner (dvl@u.arizona.edu): “I am writing you in hopes that you might set the record straight.  We have discussed with 2-3 farmers or feed companies in Mexico the ongoing problem with shrimp losses.  We have not made any official announcements about the disease in Mexico.  The government of Mexico should do this when they believe the time is appropriate for an official announcement.”

 

“We have processed only histological samples from Mexico.  We do not have the bacterial agent of the recent mortalities, from Mexico, in culture in my laboratory.  Hence, the rumors that appeared this morning on the Shrimp List from Neil Gervais and Matthew Briggs are false [Emphasis by Shrimp News].”

Pancreas Disease Cases Down so Far this Year

Date: 
11 Jun 2013

NORWAY - Cases of Pancreas Disease (PD) reported for the January to May period this year are lower than the number of cases reported during the same period of 2012.

The May PD report states that 20 cases of PD have been reported during January to May 2013.

Half of these cases are north of Hustadvika and overall there are only nine cases due to the 'old' subtype, SAV3.

The total number is under half of the total number of cases reported during the same time last year and is also slightly below 2011 (24 cases). In 2010, a total of 19 cases were reported in January-May.

It is still not possible to know whether this trend will reverse when water temperatures rise and the Veterinary Institute is closely monitoring the situation.
