Artisanal fishery at two villages in Jureia-Itatins Ecological Station, Sao Paulo State, Brazil was studied between September 2000 and August 2001, in order to analyze fish composition and yield, and their relation to environmental variables (rain, tides, and moon). Productivity analysis was made through capture per unit of effort (CPUE). In Barra do Una , 20 landings caught 282.6 Kg of 12 fish species, using 19340 m super(2) of nets, in 177.5 hours, obtaining a yield of 0.001 Kg/m super(2)/hour (CPUE1) or 1,0526 Kg/fisherman /hours (CPUE2). In Guarau, 607.9 Kg of 24 fish species were collected in 32 landings, utilizing 27320 m super(2) of nets in 246.5 hours of fishing effort, with yields was 0.0015 Kg/m super(2) /hour(CPUE1) or 1.0191 kg/fisherman/hour (CPUE2). In spite of closeness of yield values, the landings 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.
