Short summary
Geo-referenced catch and fishing effort data of the bigeye tuna fisheries in the Indian Ocean over 1952–2014 were analyzed and standardized to facilitate population dynamics modeling studies. A total of 30 fisheries were finally determined from longline, purse seine and other-gears data sets. Nevertheless, still one-third of total nominal catch is not included due to a total lack of geo-referenced information and would need to be processed separately.
