Canadian Sablefish Association
POSITION ON SABLEFISH AQUACULTURE
April 2004
1. 0 INTRODUCTION
The Canadian Sablefish Association (CSA) represents
the interests of British Columbia's commercial sablefish fleet.
First and foremost we seek to ensure the long-term sustainability
of wild sablefish stocks.
For over a decade the CSA has co-managed the
sablefish resource together with Fisheries and Oceans Canada
(DFO) in what is considered a world-class model of fishery
management. We contribute over $2.4 million annually to scientific
research, stock assessment, monitoring, enforcement and fishery
management. The CSA is a responsible, accountable and proud
steward of this valuable resource.
Sablefish aquaculture has advanced rapidly
in recent years is nearing commercial viability. Fifty salmon
farms coast-wide have been licenced to farm sablefish and
the first sablefish hatchery is under development on Saltspring
Island, BC. Sablefin Hatcheries Ltd. plans to produce ten
million fingerlings annually, a volume greater than the worldwide
sablefish catch.
Alarmingly, this has all taken place in complete
absence of environmental or economic impact studies.
The CSA is concerned for the future of the
wild fishery. We have carefully monitored the progress of
sablefish aquaculture in BC and thoroughly considered information
(or lack thereof) on how aquaculture impacts the environment
and our economy. Our research consistently reveals growing
international and domestic evidence of wide-ranging problems
that threaten to devastate wild fish stocks and their habitats
and undermine successful, sustainable fisheries and communities.
This paper details CSA concerns over how sablefish
aquaculture will impact the wild sablefish resource and fishery.
2.0 ENVIRONMENTAL CONCERNS
Sablefish, a deepwater species, is unique
to the northeastern Pacific Ocean. Juveniles mature in the
coastal inlets of Washington, British Columbia and Alaska.
What will happen if farm sablefish are introduced to open-water
net pens in these sensitive rearing grounds? So far no one
has bothered to find out. Unfortunately the lessons from salmon
farming are disturbing to say the least. Diseases and parasites
have devastated wild stocks. Escaped farm and wild fish have
interbred, undermining natural genetic diversity. Toxic sewage,
pesticides and drugs have polluted pristine rearing habitats.
And because sablefish are known to be highly migratory and
long-lived, the potential threat increases from BC's sablefish
to the entire species.
Some may question whether salmon farming can
serve as a model when considering the farming of new species
such as sablefish. While we recognize the notable differences
in the two species of finfish, it is the striking similarities
in industry development that make salmon a relevant point
of reference. As salmon aquaculture boomed ahead of effective
environmental regulatory measures, industry confidently denied
any threat to wild stocks, ecosystems and fisheries. The reality
is that most major fears expressed have come true and salmon
farming countries worldwide are now suffering the consequences.
2.1 Disease and Parasite Transfer
The unnaturally high densities of fish in
the feedlot environment of net-pens makes a prime breeding
ground for disease and parasites. Recently in BC, farm derived
parasites were implicated as the causal agent leading to the
largest salmon cohort collapse on record anywhere in the world.

pink and chum salmon in the nearshore marine environment of
British Columbia, Canada, Canadian Journal of Fisheries and
Aquatic Sciences, March 2004.
2.2 Genetic Interaction
Scientific studies have demonstrated that
escaped farm salmon will compete for wild spawning grounds
and breed with wild salmon. Sadly the hybrid offspring survival
rates decline with each successive generation threatening
extinction of the run. McGinnity, P. et. al. Fitness reduction
and potential extinction of wild populations of Atlantic salmon
as result of interactions with escaped farm salmon, The Royal
Society Proceedings B, October 2003.
2.3 Habitat Destruction
Salmon farms spoil fragile marine ecosystems
with raw sewage, pcb-laced feeds, pesticides and antibiotics.
A single salmon farm can contaminate coastal inlets with as
much raw sewage as a town of 65,000 people. Malcolm MacGarvin,

3.0 SOCIO-ECONOMIC CONCERNS
The annual landed value of Canada's commercial
sablefish harvest is approximately $30 million. Industry investment
in commercial licences, quota and vessels is nearly $300 million.
The fishery employs 300 fishermen directly and 300 more in
offloading, processing and distribution. Commercial licenceholders
invest more than $2.4 million annually in sablefish science
and fishery management. Harvesting methods sustain minimal
by-catch and stock abundance is as strong as when the fishery
began.
Wild sablefish is one of the most responsibly
managed fisheries resources in North America, due in large
part to industry's commitment to the long-term sustainability
of the resource. In many cases it provides a much-needed means
of diversification for struggling fishermen from other sectors
such as salmon. By allowing them to remain viable, the sablefish
fishery helps to sustain the commercial fishing industry as
a whole.
The following socio-economic concerns outline important issues
to consider before sablefish aquaculture is allowed to proceed.
3.1 Market Collapse
Sablefish markets are located primarily in
Asia, mainly Japan and Hong Kong. Exports bring valuable net-income
to Canada, as opposed to redistribution of income within the
country. This high-end niche market is small but very well-established
based on high product quality. Should Sablefin Hatcheries
proceed with production on the scale proposed, they will more
than double the current supply of sablefish to the market.
This excess supply will push market prices to drop substantially.
Such a serious market crash would render both the wild fishery
and the sablefish farms economically unviable.
As with salmon farming, the technology and
expertise will be exported to countries with much lower costs
of production. The large multi-national corporations that
own and operate the aquaculture industry have no commitment
to Canada or our wild resources. With no accountability, it
is inevitable BC will serve merely as a means to an end. For
wild and farm industries it will be is a lose-lose situation.
3.2 US Relations
Alaska's commercial sablefish harvests are
valued at $120 million, while Washington State harvests bring
in approximately $20 million. Their combined landed value
is more than four times that of BC's harvest.
Unfortunately, what BC does could seriously
affect these US fisheries. Sablefish stocks are highly migratory,
traveling from coastal inlets further south than California,
as far north as Alaska's Aleutian Islands, and vice-versa.
This puts the entire species at risk from the threats posed
by BC's shamefully blind development of sablefish farming.
With Alaska's "no aquaculture" policy
clearly prioritizing wild stocks over fish farming, BC's actions
will do little to foster healthy Canada/US relations on fisheries.
3.3 Depletion of Global Fish Supply
It takes three to six pounds of wild fish
(as feed) to produce one pound of farmed salmon. Contrary
to common belief, aquaculture actually depletes the world
supply of fish by taking more out as feed than it produces.
By promoting over-fishing of the bottom end of the food chain,
the balance of nature is compromised and long term effects
could be disastrous. Naylor, R. L. et. al. Effect of Aquaculture
on World Fish Supplies. Nature, Vol. 405: pp. 1017 - 1024,
June 2000.
3.4 Public Health Risk
Analysis of salmon fillets from about 700
farmed and wild salmon produced in eight major farmed salmon
producing regions and purchased in 16 large cities in North
America and Europe found significantly higher concentrations
of pcb and dioxin contaminants in farmed salmon than in their
wild counterparts. Hites, R. A. et. al. Global Assessment
of Organic Contaminants in Farmed Salmon, Science Vol 303,
January 9, 2004.
4.0 RECOMMENDATIONS
The CSA recommends an approach to sablefish
aquaculture consistent with federally mandated precautionary
approach to resource management as follows:
4.1 Moratorium
Until effective measures have been put in
place to protect the wild sablefish resource and ensure the
responsible development of sablefish aquaculture, provincial
and federal governments must place all existing sablefish
aquaculture permits on hold, and halt the issuance of new
sablefish aquaculture permits. It is imperative that no farm
sablefish be permitted in open-water net pens until all risk
factors have been properly addressed.
4.2 Environmental Assessment
Evidence of ecological threats posed by aquaculture
constitute an unacceptable risk to the wild sablefish resource.
Sablefish aquaculture must undergo a species-specific Canadian
Environmental Assessment Agency (CEAA) environmental assessment.
This assessment must be based on the federally proposed volume
of 150,000 tons annual production. Regional sablefish scientists
must be included in the assessment process and open and transparent
stakeholder consultation must take place.
The CEAA assessment includes an Aquatic Organism
Risk Analysis which claims to evaluate the risk of genetic,
ecological, disease and parasite impacts. To effectively assess
the risk factors associated with sablefish aquaculture, this
analysis must address the probability and consequences of
the following:
4.2.1 Farm sablefish escape from open-water
net pens
4.2.2 Wild juvenile sablefish exposure to
farm sablefish spawn
4.2.3 Genetic interaction between farm sablefish
and wild sablefish
4.2.4 Disease and/or parasite transfer from
farm sablefish to wild sablefish
4.2.5 Disease and/or parasite transfer from
farm salmon to wild sablefish
4.2.6 Genetic impacts of farm sablefish spreading
to wild sablefish outside BC
4.2.7 Disease and/or parasite infestation
from farms spreading to wild sablefish outside BC
4.2.8 Wild sablefish exposure to sablefish
farm sewage, feeds, pesticides and antibiotics
4.2.9 Juvenile sablefish rearing habitat destruction
resulting from sablefish farms
4.2.10 Sablefish aquaculture lighting techniques
negatively impacting wild juvenile sablefish stocks
4.2.11 Domestic selection process impacts
on farm sablefish or wild sablefish
Mitigation measures must be taken for all
risk factors where a probability of negative impact exists,
before sablefish aquaculture proceeds.
4.3 Socio-Economic Cost/Benefit Analysis
A comprehensive socio-economic cost/benefit
analysis must be conducted to determine the impact of sablefish
aquaculture on:
4.3.1 The wild sablefish fishery and markets
4.3.2 The commercial fishing industry in general
4.3.3 Coastal communities reliant on the sablefish
industry
4.3.4 Provincial and federal economies
4.3.5 US relations and sablefish fisheries
4.3 Traceability
Conservation and protection of wild sablefish
stocks will require implementation of traceability measures
to clearly distinguish farm from wild sablefish at all levels
of production, harvesting, distribution, marketing and sales.
4.4 Security of Access
DFO policy to prohibit reallocation of wild
sablefish resources for aquaculture or holding pen research
initiatives, without compensation to resource stakeholders.
5.0 CONCLUSION
Globally, aquaculture is an industry that
has grown too rapidly to be regulated effectively. Countries
worldwide have failed to implement and enforce effective measures
to protect coastal ecosystems, fisheries and communities.
At the same time, aquaculture has fallen under the control
of very short list of foreign multi-national corporations.
Companies that have political influence but hold no accountability
to the ecosystems, fisheries and communities they devastate.
BC is struggling for survival in this intensely competitive
global market and the downturn is expected to continue. Salmon
farmers are increasingly desperate to diversify. As the aquaculture
industry pressures governments to allow hasty expansion to
lucrative new species, a blind eye is turned to evidence of
salmon farming's widespread environmental devastation.
The CSA remains committed to doing everything
necessary to protect the wild sablefish resource and ensure
that is does not fall prey to the tragic events unfolding
in salmon aquaculture. We will direct our efforts to government,
politicians, courts of law, media, industry and the public
to fulfill our responsibility as proud stewards of the sablefish
resource.
