| ABSTRACT The bluefish, Pomatomus saltatrix (Linneus 1766) is captured by industrial, artisanal, and recreational fisheries throughout its distribution range. The reproductive biology of P. saltatrix in the southwestern Atlantic was studied using 1,102 specimens captured by the Brazilian commercial fleet between March 2014 and December 2015. The recruitment period was identified from records of juveniles in experimental beach seine hauls carried out on sandy beaches in the external sector of Guanabara Bay for four years (2012-2015). Based on the reproductive indices and on the macro- and microscopic analyses of the gonads, spawning peaks were identified in autumn and spring. The size at first maturity was estimated at 35.5, 38.3, and 37.4 cm for females,... |

| 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 =... |
