- MORATORIUM ON EAST COAST FISH STOCKS NEEDED TO SAVE FISHERY,
- GREENPEACE TELLS CROSBIE
-
- HALIFAX, Canada December 14, 1992 (GP) The environmental
- organization Greenpeace today demanded Federal Fisheries Minister
- John Crosbie implement a total moratorium on the groundfish fishery
- in all of eastern Canada, saying that only a short-term closure
- will make the fishery viable in the long-term.
-
- A report released by Canadian Atlantic Fisheries Scientific
- Advisory Committee (CAFSAC document 92/7) shows all groundfish
- stocks (cod, haddock, plaice, pollock, redfish) to be close to
- record low levels, with below average numbers of young fish
- expected in the next several years.
-
- According to Greenpeace Fisheries Campaigner Bruno Marcocchio, "The
- overall picture is one of a classic total ecosystem collapse. The
- small-size-to-age ratio of the fish, along with their low
- abundance, indicates the system needs a rest if fish species are to
- be saved from commercial extinction."
-
- Canadian scientists have been pressured by the Minister to conform
- their advice to the political agenda of the government. The CAFSAC
- advice for cod in southern and western Newfoundland and Sydney
- Bight (3Ps,4RS3Pn, 4Vn) all show this disturbing trend. In southern
- Newfoundland (3Ps), population estimates from Canadian and French
- research vessel surveys for 1992 are considerably lower than for
- 1991. Canada's survey showed a 70% decrease; France estimated a 95%
- decrease in population. Despite this, CAFSAC is recommending a
- quota cut of only 45%, or 20,000 tonnes.
-
- Canadian scientists have repeatedly ignored warnings from fishers
- that stocks are in decline and the dumping and discarding of
- undersized fish by the mobile dragger fleet is now out of control.
- In 1988 alone, reported discards totalled 11,800,000 fish in NAFO
- the southern Gulf and Sydney Bight (areas 4T and 4Vn). The actual
- number of discards was likely much higher.
-
- "John Crosbie is playing politics with both the ecosystem and
- coastal fishing communities throughout the Maritimes," Marcocchio
- said. "To avoid the pain of a short-term closure and a compensation
- package he will destroy the livelihood of coastal fishers and the
- ecosystem that has supported them for centuries."
-
- The single-species management models that view species in isolation
- have been a dismal failure not only in Eastern Canada but
- throughout all the range of the northern cod complex. For the
- impacts of a given level of fishing to be understood, this model
- must be replaced with an ecosystem-based model that factors in the
- interrelationship of various fish species, marine mammals and
- seabirds. There must be feedback mechanisms built in that allow
- action to be taken when the system shows signs of decline rather
- than ignoring even clear signs of total collapse.

- A PRECAUTIONARY APPROACH TO FISHERIES MANAGEMENT
-
- A cornerstone to any sound approach to fisheries must be the
- adoption of precautionary management criteria and objectives. It
- is common sense to attempt to determine the effects of what you are
- about to do before you do it, or, if that is not possible, to
- ensure that the consequences of uncertainty and miscalculation are
- minimal.
-
- As a rule, fisheries management decisions are based on drastically
- inadequate estimates of poorly understood biological processes.
- Scientific certainty regarding changes in complex ecosystems can
- not be achieved. A precautionary approach implies that the health
- of ecosystems and species must be granted the benefit of the doubt
- rather than placing the burden on the environment to show signs of
- crisis before remedial action is taken. This means that, if
- adverse impacts on target and non-target species are detected, the
- fishery can be modified or even closed in time to prevent serious
- damage to the viability of affected populations.
-
- An effective management system consists of several interacting
- components:
-
- - a statement of the strategic objectives of fishery
- management ( what results are desired from the
- management)
- - for each fishery, operational interpretations of the
- strategic objectives are required which can be expressed
- in quantitative terms (to allow an evaluation to be
- made of whether or not the objectives are being met)
- - a scientific procedure or set of rules for determining
- the management measures to be imposed (TACs, effort
- limitation, mesh size, etc.) from the available data.
- This procedure must have been tested by simulation and
- demonstrated to be capable of meeting the operational
- objectives with a high probability, in spite of the
- various types of uncertainty inherent in fisheries
- management.
- - built in feedback mechanisms to respond to changes in
- the environment no matter what their cause.
