More than 35,000 fishes have been sampled at the Seychelles cannery during 1987-2014 to collect morphometric data and information on the reproduction of the principal market tropical tunas har- vested in the Indian Ocean. Samples are largely predominated by large yellowfin tuna but sampling operations have included juveniles of yellowfin as well as skipjack and bigeye since January 2014. Information on the dates of origin and fishing grounds has been retrieved from the purse seiner log- books for most fish sampled. Data collected are useful for deriving conversion keys between lengths and weights, identifying spawning grounds and fishes in sexual activity, and monitoring long-term changes in condition. A generic database is currently in development to host different types of bio- logical data and provide free open-access to the data so as to promote comparative analyses between populations, species, and areas.
