Chondrichthyes, occurrence, gillnet, coastal area


The distribution of elasmobranchs in the bottom gillnet fishery of 'Barra de Guaratiba' (RJ, Brazil) was checked between March 1982 to May 1985. An amount of 892 specimens of 25 species were registered. Rhizoprionodon porosus, R. lalandii and Sphyrna lewini were considered constants during the whole period. Rhizoprionodon species use the area as a nursery ground, meanwhile others (as Sphyrna lewini juveniles), for recruitment. None relationship between catches and moon phases were detected. Recent data, collected between 2004 and 2007, indicate the fishery pattern does not change, besides the gillnet length have grown and the catches fall.
