March 9, 2016 — Fisheries on the West Coast of America have come under intense pressure after closures and a dramatic fall in stock levels. Adrian Tatum looks at the challenges over the last few years.

Sometimes when something is broken it seems almost impossible to fix. Commercial fishing on the West Coast of America is far from broken but parts of it do need fixing.

Nearly a year ago its commercial sardine fishery was closed after the population of Pacific sardines had fallen to alarming levels. In April last year, scientists made a recommendation for full closure after the population was estimated to be below 150,000 tonnes. It has been a dramatic decline, as in 2007 there were 1.4 million tonnes.

The sardine fishery has not only been a major revenue source for West Coast fishermen, but many other species of fish such as tuna also rely on a plentiful supply for food. Scientists believed that by closing it last year it would give the population a chance to recover. But just last month, it was revealed that the sardine population has not recovered, and is in fact still declining at a fast rate. Scientists from the National Marine Fisheries Service say that by the summer, the population is likely to be 33% lower than in 2015.

Bycatch reduction

Like most fisheries around the world, West Coast fishermen are facing up to a bycatch reduction plan. The North Pacific Fishery Management Council is considering a plan which would allocate individual bycatch caps to groundfish vessels in the Gulf of Alaska rather than targeting specific large species. Back in 2011, the council passed a series of salmon and halibut bycatch reductions which angered fleet owners and fishermen. Now many Gulf of Alaska fishermen feel the recent changes will have a ‘crippling’ affect on its groundfish fleet.

Approximately 85% of the North Pacific groundfish fisheries are rationalised. This means fish quotas are assigned to individual vessels or fishing cooperatives. It is widely believed by some experts that this is the best way to ensure minimal bycatch, meaning vessels can fish without a time limit and are therefore more likely to avoid some of the endangered species such as salmon and halibut. But this process can also have a negative effect on the industry. Recent years have seen rationalisation being applied to the Bering Sea crab fishery where the number of boats fishing for crab fell by two thirds in just one year, with the loss of over 1,000 jobs.
