Spatio-temporal variation in surf zone fish communities at Ilha do Cardoso State Park, São Paulo, Brazil

In order to analyze the time-space variation of the fish fauna in the surf zone fish communities at Ilha do Cardoso State Park, São Paulo, Brazil, four consecutive hauls were done over a year on three beaches with different degrees of exposure, at low and high tide. To evaluate the influence of each...
