Abstract: Artisanal fishery at two villages in Jureia-Itatins Ecological Station, S (a) over tildeo Paulo State, Brazil, was studied between September 2006 and August 2001, in order to analyze fish composition and yield, and their relation to environmental variables (rain, tides and moon). Productivily analysis was made through capture per unit of effort (CPUE). In Barra do Una, 20 disembarkations caught 282.6 kg of 12 fish species, using 19340 m of nets, in 177.5 hours, obtaining a yield of 0.001 kg/m'/ hour (CPUE1) or 1.0526 kg/fisherman/ hour (CPUE2). In Guarau, 607.9 kg of 24 fish species were collected in 32 disembarkations, utilizing 27320 m' of nets in 246.5 hours of fishing effort, with yields was 0.0015 kg/m'/hour (CPUE1) or 1.0191 kg/fisherman/hour (CPUE2). In spite of closeness of yield values, the disembarkations composition at these two villages was distinct, with only 33% similarity (jaccard Index). A fish collection of 54 species belonging to 28 families was made.
