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

Ano: 1998 URL: http://hdl.handle.net/1834/54 New sampling strategy for purse seiner fleets in the Atlantic and Indian oceans. OceanDocs Herrera, M.A.; Evrat, F.. A new sampling system for Spanish, French and NEI purse-seiners was developed by French (ORSTOM) and Spanish scientists (I.E.O. and O.E.P.) working together on the European Union Program: “Analyse du schéma d’échantillonnage multispécifique des thonidés tropicaux”. The OEP and the ORSTOM have introduced it to the samplers, in three of the four most important tuna transhipment ports in the Indian Ocean as from March 1998. This sampling method does not take into account the differences between flags of vessels, but relies on 80 newly defined strata (2 types of schools, 4 quarters and 10 areas). Each sampling needs two rounds, with a target number depending on the species and size of the fish to be measured and counted per round. A target has been established...

OceanDocs Pallares, P.; Delgado de Molina, A.; Ariz, J.. This document contains summary statistics of the Spanish purse seine fleet fishing in the Indian Ocean, as well as some information about how the data are collected. The sampling scheme, the sampling coverage, maps and diagrams representing the fishing pattern of this fleet by time and area strata are presented.

OceanDocs Uozumi, Y.. In the present analysis, CPUEs of swordfish and billfishes are standardized with fine-scale statistics to eliminate some possible biases in the CPUE trend which may be introduced by the factors mentioned above.
