Abstract


The small scale fisheries (artisanal) on the northern coast of São Paulo have been being an important and traditional fishing activity in the region. In order to analyzing the ichthyofauna caught in a stationary uncovered pound net, a total of 250 landings performed between June 2005 and April 2006 were analyzed. Species were identified and analyzed monthly using cluster analysis, multidimensional scaling, similarity analysis and similarity percentage analysis. A total of 2713.00 kg of fish were caught. Nine species contributed with more than 90% of the total weight (Trichiurus lepturus, Scomberomorus cavalla, Caranx crysos, Opisthonema oglinum, Selene vomer, Scomberomorus brasiliensis, Pomatomus saltatrix, Chloroscombrus chrysurus and Cynoscion microlepidotus). The ecological multivariate analyzes applied did not allow to detecting a pattern of variation in the ichthyofauna of the area, due to the constancy and abundance of main species, common in the area and along the coast.

 

Keywords: abundance, CPUE, similarity, small scale fishery.
