There is talk of a need for a comprehensive environmental review for the shellfish farming industry. I strongly believe that all industries should go through a similar EA process to see how they can do their part in lessoning any environmental effects.
After all, it's not just miners, or fossil fuel explorers that effect our environment. Laws should not be non-biased and regulations should be across board. JMO

Shellfish Farming

Shellfish farming is an important industry is some communities around our region, including Baynes Sound (where about half the province’s oysters are grown), Okeover Inlet and Cortes Island.
In recent years the BC government has encouraged the industry to expand through increasing the area under tenure, engaging First Nations and developing new areas of the coast.
However, applications for new farms or expansions have often sparked controversy, particularly as new technology is introduced and shellfish production intensifies.
Underlying the controversy are three fundamental issues that must be addressed:
Carrying capacity:
-
How much can the density of oyster or clam farming be increased on a beach, without impacting the long-term health of the beach’s ecosystem?
-
How much of the beach can be covered by predator netting without causing a problem?
-
How much area can be put into shellfish production without losing essential bird habitat?
-
Shellfish eat phytoplankton. Many other animals also rely on phytoplankton, which is the base of the marine food chain. How densely can an area be stocked with shellfish, without reducing the supply of phytoplankton needed by other marine life?

The answers to these questions are simply not known, because no comprehensive environmental study has been done of the industry’s cumulative impacts.
We don’t really know the carrying capacity of the marine environment for the shellfish farming industry – either at the current level or with future expansion.
We need to better understand complex ecological relations -- otherwise we might discover, too late, that changes induced cannot be easily reversed.
What’s needed is a comprehensive environmental review to determine:
-
baseline data, so that resource managers can properly measure the industry’s impacts
-
short-term, long-term and cumulative impacts, at both current and expanded levels
-
the carrying capacity of the marine environment to support the industry, both in its beach-based and deep-water forms
-
socio-economic impacts, including impacts on other users – for example, what would be the impacts of expansion of deep water tenures on:
- other commercial users such as prawn fishermen
- recreational and commercial boaters in terms of access to navigable waters and safe harbours
- outdoor tourism.
Enforcement
In order to protect the public interest, government agencies must be able to enforce best management practices and the highest possible operating standards – particularly for an industry that operates in public waters.
Yet standards for shellfish industry practices are voluntary, and best practices are not well defined. While many shellfish farms demonstrate excellent stewardship, some operations do not, and government agencies have been slow or reluctant to intervene. Existing regulations are often not enforced, and coastal aquaculture plans have allowed some practices that contravene the federal Fisheries Act (for example, extensive predator netting adjacent to the mouth of a salmon-bearing stream).
Before further expansion of the shellfish industry is considered, effective enforcement must be implemented– just as we would expect for any other industry.
Conflict with local communities & other users
British Columbians are a long way from consensus in their attitudes towards the shellfish industry.
Within Islands Trust-administered areas, conflict has occurred when applications for new or expanded sites have not respected local Trust Council zoning decisions.
Beyond the issue of siting, many other contentious issues have caused ongoing conflict between the industry and local residents and/or other users. Unless addressed, this is likely to worsen with expansion.
Many of the contentious issues should be resolvable. What’s needed is an effective, ongoing dispute resolution process that:
-
actively engages local communities, industry and government
-
provides a structure and process for resolving conflicts
-
encourages sharing of new
information from scientific studies and anecdotal data
-
provides a community-level forum for addressing some of the fundamental issues associated with the industry
