“…It is likely that the E. brasilianus may migrate for reproductive purposes from fresh water to coastal environment, having sheltered and good food supply near the mouth of a river as a transitional environment/area, thus completing their reproductive cycle. Such hypothesis is consistent with the findings of Chaves & Otto (1998) with rhombeus Diapterus species, and also with Barbanti et al (2013) analyzing the fauna fish in the Bertioga Channel in São Paulo.…”

ABSTRACT.Eugerres brasilianus is an appreciated commercial species in the market of the northeastern region of Brazil. The purpose of this study was to analyze and determine the diet, reproductive period, and management of carapeba in recirculating aquaculture systems. The fishes were caught with a gillnet at two different places near the São Francisco River mouth. The stomach content was analyzed according to the frequency of occurrence method, using the index of relative importance, assessing the degsubjectedree of stomach repletion. The reproductive period was established by determining the gonadosomatic index and gonad maturation stages. The behavior and management of the fish were observed in captivity when subjected to artificial diets in cultivation tanks. The striped carapeba is best feed at dusk, mainly Crustacea Amphipoda, Insecta Chironomidae and Crustacea Tanaidacea. The species has parceled spawning, which occurs from February to March and from July to September. There are morphological differences between males and females, especially in the urogenital papilla, size and color. In captivity, the best fish density was between 7 and 8 fish m , showing a good rates of centesimal composition, adapting well to the supplied diet. Keywords: Gerreidae, feeding, behavior, sexual maturation, reproductive period, aquaculture. Potencial de la mojarra (Eugerres brasilianus) para su cultivoRESUMEN. Eugerres brasilianus es un pez marino comercial importante en el mercado del noreste de Brasil. El objetivo de este trabajo fue analizar y determinar la dieta, período reproductivo y manejo de la mojarra en estanques de recirculación de agua para el cultivo intensivo. Los peces fueran capturados con redes agalleras en dos sitios diferentes, cerca de la desembocadura del río São Francisco. Los contenidos estomacales fueron evaluados mediante el método de frecuencia de ocurrencia, através del índice de importancia relativa, evaluando el grado de repleción del estómago. El período reproductivo fue establecido determinando el índice gonadosomático y los estadios de maturación gonadal. Se observó el comportamiento y manejo de los peces en cautividad cuando son sometidos a dietas artificiales en estanques de cultivo. La mojarra se alimentó mejor en el crepúsculo, principalmente de Crustacea Amphipoda, Insecta Chronomidae y Crustacea Tanaidacea. La especie tiene desove parcelado, que ocurre de febrero a marzo y de julio a setiembre. Existen diferencias morfológicas entre machos y hembras, especialmente con relación a la papila urogenital, tamaño y color. En cautividad la mejor densidad de peces fue entre 7 y 8 ind m -3 , mostrando buenas tasas de composición centesimal, adaptándose bien a la dieta suministrada.

“…A. januaria forms large schools and is associated with the internal areas of bays and estuaries; it is influenced by continental drainage and less saline waters. Juveniles of D. rhombeus prefer shallow mesohaline areas, such as beaches and mangrove channels, to grow and store somatic reserves during the reproductive period (MENEZES; FIGUEIREDO, 1980;OTTO, 1998). H. clupeola (zooplanktivorous marine straggler) and A. tricolor (zooplanktivorous estuarine species) were more abundant in the euhaline sectora finding was not in accord with observations from other estuaries (FALCÃO et al, 2006;FÉLIX et al, 2006;OLIVEIRA-NETO et al, 2008;CONTENTE et al, 2011a).…”

A B S T R A C THere we test the effects of the east-west salinity gradient in the subtropical Paranaguá Bay Estuarine Complex (PEC) on the structure of shallow water fish fauna, determined according to taxonomic (families and species) and functional composition metrics. A total of 152 species were observed. The families with the largest number of species were the Sciaenidae, Carangidae, Haemulidae and Gobiidae. The most abundant species were Atherinella brasiliensis, Harengula clupeola, Anchoa januaria and Anchoa tricolor. Marine stragglers dominated in number of species, followed by marine migrants and estuarine species. Most species were zoobenthivores, followed by piscivores and zooplanktivores. Families and species more frequently associated with estuarine conditions dominated in the mesohaline sector, and those more frequently associated with marine conditions dominated in the euhaline sector. The fish assemblages along the estuarine salinity gradient were found to be better characterized by taxonomic metrics than by functional ones. This is most likely because individuals of all functional groups inhabit all salinity sectors, and thus these metrics are not useful for differentiating assemblages along salinity gradients. Our results differ from those of other studies in tropical and subtropical estuaries, which have emphasized the importance of functional groups in determining fish assemblages along salinity gradients. R E S U M ONeste trabalho foi testado o efeito do gradiente de salinidade do eixo-leste oeste do sistema subtropical Complexo Estuarino da Baía de Paranaguá na estrutura dos peixes de águas rasas, determinado de acordo com as métricas taxonômica (famílias e espécies) e de composição funcional. Um total de 152 espécies foi registrado. As famílias com maior número de espécies foram Sciaenidae, Carangidae, Haemulidae e Gobiidae. As espécies mais abundantes foram A. brasiliensis, H. clupeola, A. januaria e A. tricolor. Os visitantes marinhos dominaram em número de espécies, seguidos pelos migrantes marinhos e estuarinos. A maioria das espécies são zoobentívoras, seguidas pelas piscívoras e zooplanctívoras. As famílias e espécies mais relacionadas com condições estuarinas dominaram no setor mesohalino e aquelas mais relacionadas com condições marinhas dominaram no setor euhalino. A métrica taxonômica foi mais eficiente na caracterização das assembleias de peixes ao longo do gradiente estuarino de salinidade do que a funcional. Isso ocorreu principalmente porque indivíduos de todos os grupos funcionais estiveram presentes ao longo de todos os setores de salinidade, invalidando o emprego dessa métrica na diferenciação das assembleias nos diversos setores. Nosso resultado foi diferente do encontrado em outros estuários tropicais e subtropicais, que enfatizaram a importância dos grupos funcionais na estruturação das assembleias de peixes ao longo de um gradiente de salinidade.

“…Studies with silver mojarra have been conducted on its biology (ETCHEVERS, 1978;CHAVES;OTTO, 1998;SILVA et al, 2011) and distribution aspects (ARAÚJO; SANTOS, 1999;AYALA-PEREZ et al, 2001;COSTA et al, 2012). However, the digestibility of ingredients has not been the subject of research and this is a major step for the development of an efficient diet to promote a better nutritional status for the animals.…”

Knowledge on the nutritional value of feed ingredient is an important step in the formulation of diets in order to maximize animal productivity. Thus a study was conducted to determine the apparent digestibility coefficients (ADC) of dry matter (ADCDM), crude protein (ADCCP), gross energy (ADCGE) and amino acids (ADCAA) of conventional feed ingredients for juvenile silver mojarra (13.0 ± 3.23 g). The study was conducted in the laboratory for nutrition and feeding of fish (AQUANUT), using 80 silver mojarra collected in nature, which were kept in digestibility aquaria for a period of 21 days. The following ingredients were evaluated: fish meal, soybean meal, corn meal, corn gluten meal, rice bran, wheat bran and starch, which substituted 30% of a reference pelletized diet with 325.00 g kg crude protein and 3,692 Kcal kg -1 gross energy. Additionally 1.0 g kg -1 chrome oxide was added to each diet as a marker. The excreta were obtained using three repetitions for each tested ingredient, which were dried for further analyses. The soybean meal showed the best ADCDM value (67.45%), followed by the other ingredients. There was no significant difference between the soybean meal (95.16%), fish meal (92.97%) and the corn meal (91.90%) for the best ADCCP coefficients. The ADCGE for soybean meal and maize meal were 65.23% and 60.31%, respectively, followed by fish meal (51.85%). The results demonstrate that silver mojarra can digest animal protein as well as that of vegetal origin. Silver mojarra can also efficiently digest and absorb some of the main amino acids of fish, such as lysine, methionine and threonine, from the same studied ingredients. Key words: Acará-peba.

Foi realizado um estudo para determinar os coeficientes de digestibilidade aparente (CDA) da matéria seca (CDAMS), da proteína bruta (CDAPB), da energia bruta (CDAEB) e dos aminoácidos (CDAAA) de ingredientes convencionais para juvenis de carapeba (13 ± 3,23 g). O estudo foi realizado no Laboratório de Nutrição e Alimentação de Peixes (AQUANUT), utilizando 80 exemplares de carapeba, coletados na natureza, que foram mantidos em aquários de digestibilidade no período de 21 dias. Foram avaliados os seguintes ingredientes: farinha de peixe, farelo de soja, fubá de milho, farelo de glúten de milho, farelo de arroz, farelo de trigo e amido, que substituíram 30% de uma dieta referência peletizada com 325,00 g kg -1 de proteína bruta e 3,692 Kcal kg -1 de energia bruta, utilizando 1,0 g kg -1 óxido de cromo como marcador. As excretas foram obtidas utilizando três repetições para cada ingrediente testado, e após a secagem foram realizadas as análises laboratoriais. O farelo de soja apresentou o melhor resultado para o CDAMS (67,45%) seguido pelos demais ingredientes. Para o CDAPB não houve diferença significativa entre o farelo de soja (95,16%), a farinha de peixe (92,97%) e o fub...
