Este trabalho trata da distribuição e abundância das principais espécies de peixes bentônicos explotados pelos linheiros ao largo do sudeste do Brasil (latitudes 18º-26ºS), no período 1986-1995, listadas a seguir, com as respectivas participações no total das capturas: batata = Lopholatilus vilariii Ribeiro = 33,4%, namorado = Pseudopercis numida Ribeiro = 18,4%, cherne = Epinephelus niveatus (Valenciennes) = 12,1%, garoupa = Epinephelus marginatus (Lowe) = 4,1% e badejo = Mycteroperca bonaci (Poey) = 3,1%. As pescarias ocorreram em águas tropicais (latitudes 18º- 23ºS) e subtropicais (latitudes 23º-26ºS), tendo como divisor zoogeográfico a ressurgência de Cabo Frio. Os dados foram agrupados por faixas de latitude e de profundidade, segundo espécies e estações do ano. As pescarias estiveram grandemente concentradas nas águas subtropicais, com tendência(s) de produtividade decrescente, à medida que aumenta(m) a latitude e/ou a profundidade dos pesqueiros explotados. Nas águas tropicais, as espécies dominantes foram a garoupa e o badejo, de forma indiscutível entre as latitudes 18º-20ºS, com maiores capturas em profundidades de até 80 metros. Nas águas subtropicais, as espécies dominantes sempre foram o batata, o namorado e o cherne, com maiores capturas em profundidades superiores a 100 metros, incluindo a parte superior do talude continental. A produção das cinco espécies principais apresentou tendências de variação estacional, mas apenas o cherne evidenciou deslocamento sazonal ao longo da costa. Foram comprovadas a menor diversidade e a maior biomassa de peixes bentônicos nas águas subtropicais.

The reproductive biology of the black grouper Mycteroperca bonaci, caught by artisanal fishermen using hook and line or compressor - assisted spear fishing, from the Northeastern shelf and oceanic banks of Brazil, was studied between August 1996 and April 1998. The sexual pattern, gonadal development, the spawning mode and seasonality were investigated. The gonadal stages indicated that this species is a protogynous hermaphrodite and that transition from female to male occurs through simultaneous re-absorption of ovarian tissue and proliferation of testicular tissue in the gonads. The specie is a multiple spawner and frequency analysis of gonadal stages and gonadosomatic index suggest that the spawning season occurs between April and September. Considerations about the fisheries, related to size structure of fishes caught, were based on length frequency distribution. The phenomenon of "correção" was described based on ethnobiology studies and informations from the Northeast Fisheries Statistics Bulletin of the Brazilian Environmental Institute (IBAMA). The phenomenon of the "correção" undergone by Mycteroperca bonaci seems to be a Southward chain reaction (of the State of Ceará to Bahia) and is a feeding aggregation.

The relationship between total length and total weight (LWR) of four commercial species of finfish captured in the southern Gulf of Mexico (Lachnolaimus maximus, Ocyurus chrysurus, Mycteroperca bonaci, and Mycteroperca microlepis) was estimated. Two of these species are captured in the region by the small-scale fleet, while the other two are targeted by small-scale and semi-industrial fleets using harpoons, handlines, and long-lines. For the assessment, the organisms were sampled at the landing decks in the study area in two periods: 1996-1999 (semi-industrial fleet) and from April 2017 to May 2018 (small-scale fleet). A total of 2780 individuals were sampled which 2775 individuals were used to obtain LWR functions. The four species showed negative allometric growth with b < 3 for the 2017-2018 period, two species showed positive allometric growth with b > 3 for the 1996-1999 period. This type of information is an important input for the stock assessment of these species that support important fisheries in the zone and are under high fishing pressure levels.
