Stock Abundance

AbstractEffective individual transferable quotas (ITQ) systems rebuild stocks and allow transfer of quotas to more efficient operators. This process requires functional markets for both quota sales and temporary quota leases. These markets are expected to respond to changes in economic rent from the fishery, which is influenced by stock abundance and the international rock lobster price. This research used multistate Markov modelling and Granger causality test to examine changes in the permanent and temporary quota trade in the Tasmanian rock lobster fishery quota market, during periods of both increasing and decreasing stock abundance. The permanent quota trade market was more active during the period of stock growth, while the quota lease market was active in both periods of stock growth and decline. In contrast to theoretical trends in ITQ fisheries, trades in both markets were not linked to the technical efficiency (i.e. catching capability) of operators, but were more driven by the quota owners' financial capacity (i.e. number of owned quotas). Prolonged and unexpected stock decline affected the quota market so that it deviated from the theoretical pattern of ITQ fisheries. Operators previously active in the market reduced their activity, while smaller operators and firms that previously had not traded became more active, so the fleet expanded with smaller operators entering.

One Year

Individual transferable quotas were successfully introduced into the Tasmanian rock-lobster fishery in 1998. In the two years since, significant industry restructuring has occurred. The move to quota management was intended to meet two key objectives: to reduce the catch to a sustainable level, allowing the stock to rebuild, and to provide a mechanism whereby the industry could achieve economic sustainability. The quota system has achieved early results on both the sustainability and restructuring objectives and is now well accepted and supported by the vast majority of fishers and licence holders. Its effect has been to reduce fishing effort by 29% and number of fishing vessels by 23%, and the reduction in catch has resulted in a 6% increase in the estimated biomass and substantial increases in egg production after one year. Fishers now spend fewer days at sea, and catch rates are improving. These changes are reducing fishing costs, which in time should increase profitability. Social costs of introducing quotas are that fewer fishers are employed on vessels and that fishers now find it harder and more expensive to lease a fishing licence. These costs must be factored into any assessment of the industry.
