| Abstract |
Many stocks of commercially-exploited fishes are overexploited with collapse as a possible consequence, especially in the case of particularly vulnerable species. This is the overarching problem of today’s fisheries. While the validity of the most alarming reports is questioned by some, the large majority of scientists agree that the current level of exploitation of many fisheries is not sustainable in the long-term. The problem of fish species' depletion is mostly caused by overfishing, IUU fishing and incidental by-catch. However, other factors such as habitat alteration or climatic variations have an important effect on the ability of stocks to replenish and thus on the level at which sustainable fishing can be set. Aquaculture and farm-ranching are presented by some of their supporters as the solution to the fishing crisis. These practices have clearly some potential as ersatz to wild-capture, but they also bring problems of their own, particularly with regard to catching juveniles as spawning stock and to the use of wild-caught fish as food for predatory aquaculture stocks. |
