Individual transferable quotas (ITQ) were implemented in the Tasmanian red rock lobster fishery in 1998 and ten years later we assessed the impacts on the fishery. Particular attention was devoted to investigating the performances of the fishery with regard to three features identified as major impacts in the literature: rationalization of the fishing fleet, change in fishing strategy in order to maximise the fisher's profit and concentration of fishing rights and activity. On average, the fishery reacted as expected and reached its objective in terms of reconstruction of the biomass, but the overall assessment in terms of resulting profitability is not very conclusive. There is no evidence of decrease of the profitability over the period of the study but the fishery is more reactive to external factors on its export market in China than to changes in its own structure.
Résumé
En 1998, les quotas individuels transférables ont été mis en place dans la pêcherie de langouste rouge de Tasmanie et dix ans plus tard, nous avons évalué leur impact sur la pêcherie. Nous avons accordé une importance particulière à l'étude des performances de la pêcherie au niveau de trois caractéristiques, identifiées par une recherche bibliographique, comme des effets majeurs de ces quotas individuels transférables : rationalisation de la flottille de pêche, changements dans les stratégies de pêche afin de maximiser le profit des pêcheurs et concentration des droits et de l'activité de pêche. En moyenne, la pêcherie a réagi conformément aux prévisions et a atteint ses objectifs en terme de reconstruction de la biomasse ; cependant, le bilan global en terme de profitabilité est mitigé. Il n'y a pas de signe de diminution de la profitabilité au cours de la période étudiée mais la pêcherie est plus réactive aux stimulus externes sur son marché d'exportation, la Chine, qu'aux changements survenus dans sa propre structure.
