Estimation of the catch-at-age matrix of yellowfin tuna (Thunnus albacares) fisheries in the Western Indian Ocean.

Abstract

This is a preliminary paper. There are many different types of gears in many different countries in the western Indian Ocean. As it was sometimes difficult to contact persons-in-charge of the fisheries statistics, not all the description of this paper (such as gear categories, classification and etc) could be checked by them.
