RESUMO:

Coastal marine fish stocks are declining rapidly, ocean fishing, geared to catch tuna and related highly migratory species, are presented as an alternative to operating. Thus, studies that relate the distribution of abundance and population structure of fish stocks environmental variables and how these relationships influence the spatial-temporal distribution are essential for the establishment of measures aimed at the sustainable exploitation of these resources. In this context, this study aimed to analyze the timeline distribution of Thunnus albacares and its relationship with oceanographic and hydrological characteristics in the Southwest Atlantic Equatorial. For this study used data capture espinheira fleet based in the state of Rio Grande do Norte, and temperature data from the sea surface (SST), Chlorophyll-a, the area between 42.2° and 24.8° W and 5.9° S and 8.8° N, in addition to data of the phases of the moon. The methodology used to model the effect of variables on the CPUE and length of captured individuals was the Generalized Linear Models method (GLM). In total 10,350 copies were analyzed, corresponding to 482.95 t. The results indicate that the abundance and T. albacares length structure have interactions with environmental variables in space and time.
