| The Lutjanidae or snappers are a family of perciform fishes, mainly marine but with some members living in estuaries and entering fresh water to feed. Some are important food fish. Cytogenetic data for Lutjanidae are scarce. In the present work, we cytogenetically characterized through conventional Giemsa staining techniques, Ag-NOR and C-banding the species Ocyurus chrysurus, Lutjanus analis, L. alexandrei, L. cyanopterus, L. jocu and L. synagris, all found along the Brazilian coast. Karyotype analysis of all six species showed a modal value of 2n = 48 acrocentric chromosomes. Single NORs were found at pericentromeric position on the long arms of the 2nd pair in O. chrysurus, L. alexandrei and L. cyanopterus, on the 5th pair in L. analis and on the 23rd... |

| Traditionally fished by line and conical fishing basket by Venezuelan ships, the red snapper resource off the coast of French Guyana (fish belonging to the Lutjanidae family) has been experiencing intensive fishing since 1984-85 due to the boom in classic fishing techniques and the development of trawl fishing. The study evaluates the situation of this resource's potential: biology, sampling data, bio-statistics (size and sex), size-weight relationship of the three species, specific composition of the catches, describes fishing devices and prospecting, pinpoints fishing spots, gives a distribution of the Venezuelan and Martinique fishing effort. |

| Traditionnellement exploitée à la ligne à main et à la nasse par les navires vénézuéliens, la ressource en vivaneaux au large de la Guyane Française (poissons appartenant à la famille des Lutjanidae) subit depuis 1984-85 une exploitation intense par l'accroissement des techniques de pêche classiques et le développement d'une pêcherie au chalut. L'étude fait le point sur les potentialités de cette ressource : biologie, données de l'échantillonnage, bio-statistique (taille et sexes), relation taille poids des 3 espèces, composition spécifique des captures, décrit les engins de pêche et prospection, localise les lieux de pêche, donne une répartition de l'effort de pêche vénézuélien et chalutier martiniquais. |

| The ornate jobfish Pristipomoides argyrogrammicus Valenciennes 1832 occurs in the Indo-West Pacific Ocean, where it is harvested by small-scale coastal fisheries. Management of this species is hindered by lack of adequate biological data. We sampled a total of 113 individuals from the landings of local artisanal fishers on the island of Réunion (southwestern Indian Ocean), from March 2014 to March 2015. The relationships between two types of body length (total and standard length, cm) and total weight (g) were shown to be significant (p < 0.05). The length–weight relationship was described by a power function, with the scaling factor estimated to be 0.008 and the exponent 3.146. Age was determined using whole otoliths. The von Bertalanffy growth... |

| ABSTRACT The main goal of this research was to investigate the differences in diet composition among three species of the genus Lutjanus inhabiting a coastal lagoon as juveniles. The working hypothesis was that these species feed on a common base of food resources and therefore, some niche overlap is present in terms of general diet composition. However, changes in the trophic niche with size and differences in some morphological traits among species explain observed differences in diet. Fish were collected during 42 sampling trips conducted regularly from February 2011 to January 2012 using several types of fishing gear. Total number of analyzed stomachs was 288 for Lutjanus argentiventris from 2.3 to 19.9 cm total length (TL); 178 for Lutjanus colorado... |

| We determined the age and growth of the dog snapper (Lutjanus jocu), caught in the region of Abrolhos Bank, Bahia State, by the fishermen from coastal communities of Prado, Alcobaça, Caravelas, and Nova Viçosa. We examined 205 sectioned otoliths of fish caught by harpoon, longline, hand line, and gill nets (14.5 to 79.5 cm fork length). The formation of each ring was considered annual. The sectioned otoliths showed between 0 and 29 rings. Nearly half of the analyzed specimens had between 0 and 7 rings (88 of 205). Fish caught with nets in the estuarine region were the juvenile, while fish caught with lines and harpoons were the oldest. Two von Bertalanffy growth models were fitted to length-at-age data: one assuming constant variance of length-at-age (SVB)... |

| This survey focused on the outer shelf and deep water slope off Ghana and the catch-distribution analyses were therefore performed for four depth strata, outer shelf (< 100 m), upper slope (100-300 m) mid slope (300-600 m) and lower slope (>600 m). In the analyses the “Demersal” group includes commercially important families as Sciaenidae, Haemulidae (=Pomadasyidae), Serranidae, Sparidae and Lutjanidae, and especially in deeper waters the Merluccidae, Macrouridae and Moridae. The Pelagic group includes Engraulidae, Clupeidae, Carangidae, Scombridae, Sphyraenidae, Gempylidae and Trichiuridae (the latter family is actually mainly benthopelagic). For the analysis the “other” group includes all species not accounted for in the groups listed. |

| RESUMOO objetivo deste trabalho foi avaliar a eficácia do anestésico natural eugenol, em diferentes concentrações, durante o processo de anestesia do ariacó (Lutjanus synagris) cultivado. Foram utilizados 108 indivíduos, divididos em três classes de tamanho: alevinos (n = 36), juvenis (n = 36), e adultos (n = 36); com pesos médios respectivos de 3,58 ± 0,63 g; 20,24 ± 5,53 g e 263,51 ± 52,20 g, para cada uma destas classes. As concentrações testadas para as três classes de tamanho foram de 25; 50 e 75 mg L-1 sendo os tempos de anestesia e de recuperação registrados com cronômetro digital. Os resultados mostraram que quanto maior a concentração eugenol utilizada menor o tempo decorrido para atingir cada estágio de anestesia, para as três classes de tamanho.... |

| ABSTRACT To determine the coral reefmorpho-functional structure of San Andrés, regarding functional benthic diversity and fish (Lutjanidae), we evaluated the condition of the coral structure on the leeward side of the island, which is an area impacted by tourism, through diving and fishing. Three sampling sites were evaluated during two years recording the distribution of benthic organisms, environmental variables and Snappers density (Lutjanidae). A low density of Lutjanusjocu and Ocyurus chrysurus was found, with a high density ofjuveniles of L. apodus and L. mahogoni, which showed a preference for reefs with submassive and brain corals. Algae especially Macroalgae and octocorals were those with the greatest coverage in the reefs, followed by inert... |
