Description
Balbaya is a detailed data base that contains all the data on catches , effort and measurements of French tropical tuna fishing. The data are obtained from the AVDTH database to which the species composition of catches is corrected and the the sample sizes are homogenized. Balbaya contains data for the Atlantic Ocean and the Indian Ocean from 1991 to 2010. more

Unlike AVDTH, Balbaya is a single database that contains both the Indian Ocean and Atlantic ocean data. It was created to correct and centralize all available data, and make it more easily accessible. This database is hosted (i) on a server (aldabra2) at CRH (UMR 212 EME), (ii) on a server of IRD in Montpellier, and is accessible upon request. Note that the Instituto Español de Oceanografía (IEO) also has a Balbaya base (identical in structure) and updated until 2010 for the Spanish data. A collaborative analysis (IRD- IEO) of the two databases is undertaken to merge the two (i.e. data of European seiners and Seychelles vessels which are actually Spanish). Balbaya is used in different organizations: CRH (Centre of Mediterranean and Tropical Fisheries Research, Sète (France) and IEO (Instituto Español de Oceanografía, Spain).
