Althought few data are available, Indian Ocean tuna resources are becoming the object of an increasingly active fishery. Between 1980 and 1985 catches grew from 275 000 t to almost 450 000 t, a 60% increase. Catches of tropical surface tuna species, mainly skipjack and yellowfin, nearly doubled during the same period, from 156 000 t to almost 300 000 t. The catch potential for these species is still largely unknow. This document summarizes present knowledge on the biology of the main species of tuna in the Indian Ocean, the oceanographic environment and its influence on production. The main artisanal fisheries are described country by country. Results of the many surveys carried out by pole-and-line fishing, with live bait, and purse seining or through aerial survey are analysed. These observations and the most recent results of commercial purse-seine fisheries give clear indications of those areas favourable to tuna surface concentration and consequently potential grounds for purse-seining and pole-and-line fishing.
