The catchability of three type seine nets was compared in seven estuarine beaches of Sao Francisco do Sul, Santa Catarina. The capture of specimens and taxa was higher in the net 2.5 mm mesh with nets of meshes 1 and 2.5 mm showing a higher number of unique species. In general terms it was noted that the nets of meshes 1 and 2.5mm capture a greater number of specimens of smaller size. In most months the average collection for net and the number of fish species, Shannon-Wiener and equitability not differ significantly. Considering the beaches separately, between the nets used in the collections were not significant differences between the mean number of specimens and equitability, with differences in the average number of fish and Shannon-Wiener. Through cluster analysis shows that nets of meshes of 2.5 and 5.0 mm shown in estuarine beaches studied in assemblies similar pattern of temporal variation, differing markedly from the temporal pattern identified with the net of mesh 1mm. In spatial terms the three nets showed different results, with a greater similarity between the assemblages sampled by nets of 2.5 and 5mm.(AU)
