1. Biometric relationships between body size and otolith size in 15 demersal marine fish species from the northern Brazilian coast
RESUMO As relações entre o tamanho corporal do peixe e as medidas do otólito sagitta foram calculadas pela primeira vez para 15 espécies pertencentes a seis famílias de peixes demersais da costa norte do Brasil. Um total de 220 peixes foi amostrado da captura acidental realizada pelo arrasto de fundo da frota pesqueira industrial de camarão entre agost

2. Life History Parameters of Genypterus brasiliensis (Teleostei: Ophidiidae), an Endemic Fisheries Resource of the Southwestern Atlantic
Abstract: Genypterus brasiliensis, a demersal fish of large size (1.3 m of total length), occurs in the southwest Atlantic (23 to 38oS) and well appreciated due to the quality of its flesh. It was analyzed through longline and trawl fisheries, and the average length and weight of 724 specimens were significantly different between them, with the biggest and h

3. Checklist of marine demersal fishes captured by the pair trawl fisheries in Southern (RJ-SC) Brazil
Resumo: Nas costas tropicais e subtropicais, sobre as plataformas continentais, os recursos pesqueiros demersais são abundantes e considerados uma parcela importante do ambiente marinho. Os recursos pesqueiros demersais marinhos são capturados por diversas modalidades de pesca, muitas vezes de forma insustentável, o que vem provocando o esgotamento de seu

4. Diel Variations and Ecological Aspects in Fish Assemblages of a Sandy Beach in the Semi-Arid Region of Northeast Brazil.
ABSTRACT For the demersal fish that inhabit sandy beaches, the variation between day and night periods represents a determinant factor in their behavior, especially for species that live in shallow waters. This research aims at determining whether there are differences in the fish assemblage structure of the sandy beach of São Cristóvão, RN, Brazil, betwe

5. Trophic Groups Of Demersal Fish Of Santos Bay And Adjacent Continental Shelf, São Paulo State, Brazil: Temporal And Spatial Comparisons
A variação temporal e espacial dos hábitos alimentares e dos grupos tróficos de peixes demersais abundantes na baía de Santos e plataforma continental adjacente foi investigada. As amostras foram obtidas em setembro de 2005 e março de 2006, utilizando-se rede de arrasto de fundo. A análise dos conteúdos estomacais de 2.328 exemplares de 49 espécies

6. ANÁLISE DA ICTIOFAUNA ACOMPANHANTE E CARACTERIZAÇÃO SOCIOECONÔMICA DA PESCA ARTESANAL DO CAMARÃO SETE-BARBAS EM PORTO BELO, SC
A pesca artesanal dirigida ao camarão sete-barbas é realizada no litoral catarinense desde 1960, sempre pelo método de arrasto motorizado com portas, onde gera emprego, renda e mantém viva a tradição cultural açoriana. Com o objetivo de analisar a ictiofauna acompanhante e caracterizar socioeconomicamente a pesca artesanal do camarão sete-barbas (Xip

7. Idade e mudanças no crescimento da pescadinha amarela Macrodon atricauda (Günther, 1880) entre 1976 e 2009 no Sul do Brasil / Age and change in growth of the king weakfish Macrodon atricauda (Günther, 1880) between 1976 and 2009 in Souther Brazil.
The coastal demersal sciaenid Macrodon atricauda (Günther, 1880), formerly M. ancylodon (Bloch and Shneider, 1801) was sampled for ageing in four periods (1976-79, 1984-86, 1995-97 and 2006- 09) from commercial fishing and scientific surveys along Southern Brazil (Lat. 30S to 3440S). Maximum observed age was seven but no fish older than five years was sampl

8. Bioconcentração e biomagnificação de metilmercúrio na baía de Guanabara, Rio de Janeiro
Methylmercury was determined in water and aquatic biota from Guanabara Bay. Trophic transfer of methylmercury was observed between trophic levels from prey (microplankton, mesoplankton and fish with different feeding habits) to top predator (pelagic demersal fish). Top predator fish presented the highest methylmercury concentrations (320.3 ± 150.7 mg kg-1 d

9. A Pesca Industrial de Emalhe de Fundo em Santa Catarina-Brasil: Dinâmica, Tecnologia, Economia e Gestão
The gillnet fishery is a passive gear used to catch fish and crustacean species. Among the industrial fleet within the State of Santa Catarina which applies this technique, the main target-species are demersal fishes such as monkfish, whitemouth croaker and argentine croaker. The current work presents a study focused on the dynamic, economical and technologi

10. Hidrocarbonetos policíclicos aromáticos no meio ambiente: diferenciação de fontes em sedimentos e metabólitos em bile de peixes
Many studies on environmental ecosystems quality related to polycyclic aromatic hydrocarbons (PAH) have been carried out routinely due to their ubiquotus presence worldwide and to their potential toxicity after its biotransformation. PAH may be introduced into the environmet by natural and anthropogenic processes from direct runoff and discharges and indirec

11. Stocks identification of the Argentine hake, Merluccius hubbsi Marini, 1933 (Gadiformes: Merlucciidae) in the South-Southeast of Brazil / "Identificação de estoques da merluza, Merluccius hubbsi Marini, 1933 (Gadiformes: Merlucciidae) na Região Sudeste-Sul do Brasil"
The Argentine hake, Merluccius hubbsi Marini, 1933, is a demersal-pelagic fish inhabiting the South and the Southeast Brazilian area, between 21°S and 34°S. Since 2001, this species has been strongly targeted by trawlers operating at the external continental shelf and the slope. Previous studies about growth, mortality and reproduction pointed the necessit
