This report card highlights the failure of the BC government to regulate the salmon farming industry. It evaluates the government's progress in implementing the recommendations that the provincial Environmental Assessment Office (EAO) handed down in 1997.
Many people, including the Minister of Agriculture, Food & Fisheries, have claimed over the intervening years that the government has successfully implemented the majority of the EAO recommendations. According to the government's own analysis, it has fully implemented 39 of the 49 recommendations. However, if you look more closely at the finer details spelled out in the EAO's report, you'll find instead, that the province has fully implemented only 10 of the 49 recommendations. As a result of this poor progress, we have given the BC government an overall failing grade (F) for its progress in addressing the environmental and social issues that were identified by its own Environmental Assessment Office.
RESEARCH TEAM COUNTS LICE ON SALMON IN BC'S BROUGHTON ARCHIPELAGO - Twyla Roscovich, 2004. CallingFromTheCoast.com
DISTRIBUTOR TOUTS 'CLEAN' FARMED SALMON ALREADY ON MARKET - Laura Cutland, IntraFish. January 13, 2004
Seattle (WA), USA: Seizing the fallout from the farmed salmon contaminant study published last week, one seafood importer says that he can source farmed salmon with more than 300 times less dioxins and 1,000 times lower PCB concentrations than were found in the wild salmon sampled in the Science study.
Richard Martin, founder of Boston-based Martin International Corp., told IntraFish that test results from an independent lab in Durham, North Carolina show that the organic Atlantic salmon he sources from four or five private growers in the Shetland Islands show significantly less amounts of dioxins and dioxin-like PCBs when compared to fish tested in Science study.
Although he only submitted two fish for testing from the Shetland farms, Martin - who provided the test results to IntraFish - said that his product shows that farmed fish that are largely free of chemicals can be produced.
For dioxins, the product tested at .0005 parts per billion. For PCBs, it tested at .0031 ppb. Compared directly with the study samples, the Shetland fish had 340 times lower concentration of dioxin and 1,532 times lower concentration of PCBs than wild salmon. When compared with the farmed salmon samples, the product fared even more favorably, he noted.
Sold under the Black Pearl/Natural Choice brand on the U.S. market, the product is made with U.K. Soil Association-certified organic feed manufactured by Ewos, he said, which uses 100 percent recycled fishery products processed for human consumption. In addition, the Black Pearl farmed salmon is produced without the use pesticides, anti-fouling agents, anti-fungal agents or antibiotics, the importer added.
His company, which also distributes wild salmon, hired Triangle Labs to perform mass spectrometry and gas chromatography tests on the fish, which cost $700 to $800 per sample. Martin said he plans to continue sampling his farmed fish - which he sells alongside a European distributor - every quarter to see if the results hold up over time.
In the meantime, Martin said business has picked up ever since the salmon colorant lawsuit and the Coastal Alliance for Aquaculture Reform's "Farmed and Dangerous" advertisement ran in The New York Times. "What really changed things for us was that New York Times ad," he said. "The price was holding them off. When the ad hit, it changed everyone's minds . . . we started to get more consistent business."
Martin typically sells about 15 tons per week of the Black Pearl/Natural Choice brand and another 15 tons weekly of the Black Pearl/Icelandic Brand to customers like Whole Foods and Dorothy Lane Market grocery chains. The product retails for about $8.99 per pound.
The issue of contaminants in farmed salmon gained a worldwide spotlight last week when a study published in the journal Science reported that researchers had found higher levels of PCBs, dioxins and other toxins in farmed fish than in wild salmon.
The authors said that farmed fish had a little over 30 ppb of PCBs while wild salmon tested at less than 5 ppb. For dioxins, farmed fish tested at more than ten times the concentrations of those in wild fish.
The researchers concluded that farmed fish may pose a health risk and recommended consuming no more than one meal per month of farmed salmon based on the U.S. Environmental Protection Agency's cancer risk assessment model.
A number of scientists have since criticized the study for discounting the health benefits of fish and have noted that the contaminant levels found by the authors fall far below safety standards established by the U.S. Food and Drug Administration.
The salmon farming industry, meanwhile, has pledged to reduce the amount of contaminants in fish feed and noted that progress has been made.

ORGANIC AQUACULTURE STANDARDS REVIEWED - The Organic Standard © Grolink AB Issue 29/September 2003
This was the first task carried out by the newly formed Aquaculture Group, a body with over forty members. Although the Aquaculture Group did not attempt to reach a consensus on questions posed by the Standards Committee, the Group nonetheless agreed on many of the issues raised. Several of those issues are presented below.
Questions raised by the Standards Committee are in bold print.
What is aquaculture? Is the proposed definition complete and correct?
The proposed definition, "the managed production of aquatic plants and/ or animals in an enclosed outdoor environment" was too restrictive for the majority of the Aquaculture Group, especially because it clearly excludes indoor, recirculating systems. These systems are highly efficient for water conservation and environmental protection.
They recycle and reuse aquaculture waste water by moving it through a series of filters (screens and biological filters that house beneficial nitrifying bacteria), which remove wastes so that the water may be used again. Generally only 5-10% of the water is replaced per day and this is due mostly to loss from evaporation and the removal of settleable solids.
Recirculating systems are often integrated with terrestrial farming operations that use the nutrient, and especially nitrogen-rich, water as an input to crop production.
Integrated recirculating aquaculture/ hydroponic systems are efficient food production systems that recycle nutrients and require few additional inputs. Nutrient-rich water from aquaculture tanks is circulated through beds of vegetables, fruits, grasses or flowers. The media used to support plants also support useful nitrifying bacteria that oxidise ammonia to nitrite and then to nitrate. Ammonia is the major nitrogenous waste product excreted by fish and can become toxic in recirculating systems if not converted to the less toxic nitrate.
Plants take up nutrients and roots serve to clarify water that is then recycled back to the aquaculture tanks. Although some conventional recirculating aquaculture systems are energy intensive, not all are. In fact, some systems integrated with hydroponic plants use very little energy and rely on plants and gravity to utilise wastes and move water through the systems.
Indoor recirculating systems are essential for the early stages of fish or shellfish rearing, and are especially necessary for farmers in regions with temperate, short growing seasons or arid climates. One Aquaculture Group member, Martin Joensen, commented that the Faroe Islands experience extreme weather conditions and that "a 100% outdoor requirement would probably make organic aquaculture in the Faroe Islands impossible". For remote areas, non-coastal regions, or urban environments, indoor aquaculture also significantly reduces food miles - the distance and energy required to transport food between producer and consumer.
The current definition of aquaculture in the 2002 IFOAM Basic Standards states that "aquaculture includes the farming of many different species using diverse forms of production in fresh, brackish and saltwater. These standards cover carnivorous, omnivorous and herbivorous organisms of all types and at all stages of growth, grown in any form of enclosure such as earthen ponds, tanks and cages (open and closed systems)." It does not exclude any species or system.
Standards for wild-harvested, i.e. capture fisheries, will, no doubt, continue to be debated for some time. Every IFOAM Aquaculture Group member that provided comments to this question agreed that:
These comments are due primarily to management issues and specifically because of a lack of control of the organisms, especially highly migratory species. Although many capture fisheries managers conduct extensive population monitoring, there is no control over what the aquatic animals consume, and particularly to what contaminants the animals are exposed.
Several Group members recommended that sustainable standards, not organic standards, be developed for capture fisheries.
There were exceptions: every member of the Aquaculture Group agreed that sedentary organisms such as certain shellfish and aquatic plants could be labelled as organic and 90% of the Group recommended that standards for these organisms be included in either the IBS aquaculture or wild harvest chapters. These organisms benefit the environment by utilising natural nutrients. They are proactively managed and monitored through the site selection of the operation (in order to provide optimal environmental conditions for the organisms), for predator and contamination control and through decisions about the density of animals per unit volume of grow-out waters and placement of organisms in the water column.
As part of a nutritionally-balanced diet piscivorous (fish-eating) fish require fishmeal and oil. Organic piscivorous fish will also require these inputs. Of the Aquaculture Group members that provided comments, 77% said that wild-caught fish should be allowed as a feed ration for organically farmed aquatic animals.
Researchers are actively trying to develop diets that require less fishmeal and oil. Some are quick to say that plant-based diets are the golden answer to organic certification.
However, this is not yet the case as some of these diets have resulted in the growth and health of piscivorous the fish being seriously compromised.
In addition, these diets can increase the susceptibility of the fish to infections from some common pathogens.
Because organic standards include the welfare of the animal, these diets do not yet appear as the best solution for organic piscivorous fish. At this stage fishmeal and oil will still be required as part of a piscivorous fish diet.
Not all fish require fishmeal and oil in their diets. But this is not readily evident in conventional aquaculture as even low-food-chain species such as carp are now raised with processed fishmeal and oil-based feeds.
For example, tambaqui, an Amazonian fish that traditionally feeds only on fruits, nuts and seeds that fall in the water during seasonal flooding, are now raised in conventional aquaculture systems with fishmeal and fish oil-based diets. Nearly 80% of the Aquaculture Group comments recommended that only piscivorous species be fed with a ration that includes fishmeal and oil in their diets.
It should be noted that there are many low-food-chain species cultured widely throughout the globe and these species can entirely bypass all the complex issues (such as sustainability of the resource, contaminants, antioxidants, energy used in harvesting and processing, importation of distant fisheries resources and nutrient disequilibria) associated with fishmeal and fish oil. These issues will be covered more in depth in a future article.
