| This communication deals with the sexual colour patterns in the sandperch Pseudopercis numida Ribeiro, 1903, a benthonic fish of commercial importance, endemic to the Brazilian continental shelf, occurring off the coasts from Espírito Santo to Rio Grande do Sul States. The males have the head, the dorsal part of the body, and the pectoral and caudal fins blackishes, whereas the females have them brown-yellowishes. Such patterns are constant characters, not related to maturity or breeding seasons. |

| This paper deals with the schooling structure of Brazilian-sardine, Sardinella brasiliensis (Steindachner, 1879), in coastal waters of Rio de Janeiro State (Brazil). Samples were obtained from schools caught by commercial fishery in the area of Angra dos Reis (23º-24ºS, 44º-45ºW), from autumn/1999 to summer/2000, comprising 2,278 fishes. In average, males had total lengths and weights lower than those of females, with major differences in weights. Seasonal fluctuations of average total weights are associated with the annual reproduction cycle and condition factor, mainly in females. Sex-ratio was around 1:1, except in winter, when females were in majority. Mature males and females were found all along the year, with a peak in the spring-summer, showing a... |

| The tilefish, Lopholatihis villarii Ribeiro, 1915 is a commercially-important demersal fish, in the Southeast Brazil, inhabiting calcareous and rocky substrates of the outer shelf and upper continental slope. This study was based on readings of the scale's age rings of 153 especimens, caught from March, 1995 to March, 1996. Scales were found to grow on an isometric proportion with fish length, and age rings are formed betvveen the third and fourth trimesters (winter and spring). The age groups of sampled fish varied from II to X years, and the growth equation in total length (cm) is Lt = I 13.4 [1-e -0.144 (t+ 1.4)] w ith the correspondem one in weight (kg): W, = 22.5[1-e -0.144 (1 + 14)]3 184 obtained from the weight/length regression equation: ln W =... |

| This paper deals with the occurrence and schol sizes of the Brazilian-sardine, Sardinella brasiliensis (Steindachner, 1879), in coastal waters of" Rio de Janeiro State (Brazil), during the years 1993-1997. The schools are more frequent and heavier in bay and surroundings of Grande Island; another area, with lesser importance, remains between the Cape of São Tome and surroundings of Cabo Frio, under influence of coastal upwelling. The heavier schools are found in April-June (autumn), soon after lhe reproduction period. The schools swim in surface waters with until 80 meters in depth. but more than 98% of them are restricted to waters until 50 meters; about 41% of schools are found in places of 10 - 20 meters, with clear reduction of their frequencies in... |
