The white croaker Micropogonias fumieri (Desmarest, 1823) is one of the most abundant fish species in the Sepetiba Bay, being heavily exploited in fisheries. Two hundred eleven fishes, captured from October 1998 to September 1999, in monthly samplings with otter trawling, were studied. The aim here is to characterize morphometrics of populations that use de Bay in order to compare with other areas. Measurements included standard length (SL), head length (HL), Pre-dorsal distance (PDD), pectoral distance (PD), ventral distance (VD) and anal distance (AD), pectoral length (PL) and eye diarneter (ED). The values of HL, PDD, PD, VD, AD, were related to SL, while ED was related to HL. Scatterplot from logaritrnized data, by sex, were analyzed in order to assess... |

The catfish Trachelyopterus striatulus Steindachner, 1877 is a very abundant fish species in reservoirs in Southeast Brazil, and its relative abundance seems to be increasing in several lentic environments. Despite of being a very common species, few information is available on its distribution and other aspects of ecology. The Lajes reservoir (22º42'-22º50'S e 43º53'-44º05'W) is the largest manmade lake for hydropower purposes in Rio de Janeiro State, where this species rank among the top abundant fishes, both in number and in biomass. Its relative abundance were compared in three zones of the reservoir (upper, central and lower), based on a standardized program, during three annual periods (monthly sampling in 1994 and bi-monthly sampling in 1996 and... |
