The yellowfin tuna stockStock:
The fish of a particular species reproducing in the same area in the same period. has been heavily overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. for the past ten years. The [fishing effort] has now been decreased. The reliability of the [stock assessments] is very uncertain. Mitigations are needed to effectively control and correct fishing effort. The most recent stock assessment showed that the stock is much smaller than previously assumed. The stock is still being overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. .
Fishing with [purse seine] with [FADs] has much bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards). of young tuna and undesired species like sea turtles, seabirds, rays and sharks. These include vulnerable and endangered species.
The IOTCIOTC:
Indian Ocean Tuna Commission, an international organization dedicated to the management of tuna and tuna species in the Indian Ocean and adjacent seas. is responsible for the management of tuna in the Indian Ocean. There are several problems with the management. There is no [catch limit] set and there are no effective tools to oversee and correct the fishing effort. The [illegal fishery] on yellowfin tuna is still considerable: 18-32% of the total catch. Measures to address unwanted bycatch are not taken. The IOTC has made a resolution to deal with the finning of sharks, but due to the lack of surveillance and control at sea, this initiative has little effect.
