The Effects of the Pot Reduction in the South Australian Southern Zone Rock Lobster Fishery

Previous research has shown that the South Australian Southern Zone rock lobster fishery is economically over exploited, implying that a reduction in fishing effort will improve economic efficiency in the fishery. A scheme, consisting of a mandatory pot reduction of 15%, and the replacement of the potlvessel allocation formula with minimum and maximum pot entitlements of 25 and 80, respectively, was introduced in the fishery in September 1984 for this purpose. Analyses of the effect of the scheme on fishing effort and the number of fishermen, and some observations on the response of fishermen to the scheme are provided. While the pot reduction has had a small effect on fishing effort, it has failed to induce significant rationalization within the fishery. Remaining fishermen have responded by working a smaller number of pots more intensively than they had prior to the introduction of the scheme.
