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. Measures 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:

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 governance of tuna in the Indian Ocean. There is no [catch limit] established and supervision and control is weak on this fishery.

Fishery data on catches and bycatches is therefor unreliable and incomplete.
