A piscicultura moderna baseia-se no melhor sistema de criação, qualidade ambiental e ganhos de produtividade. Neste experimento foi analisado o efeito da densidade de cultivo na qualidade da água, e posteriormente, no desempenho zootécnico dos tambaquis (Colossoma macropomum). Os juvenis de tambaqui com 13,6 ± 4,1g de peso médio foram mantidos em canais de abastecimento com 40 metros de extensão, dividido em quinze seções de um metro cúbico. Foram testadas três densidades (60, 90 e 120 peixe m-³) em delineamento experimental inteiramente casualizado, com cinco repetições. Os resultados dos parâmetros físico-químicos da água foram: temperatura variou de 28,0-31,7 °C, o oxigênio dissolvido de 5,9-7,4 mg L-1, o pH de 6,8-7,5, a concentração média de amônia ficou ao redor de 0,1-0,3 mg L-1. Os valores de alcalinidade e dureza foram de 24,0-34,0 mg L-1 (CaCO3) e 24,0-37,0 mg L-1 (CaCO3, MgCO3). A condutividade elétrica variou entre 0,07-106 µS cm-1 e a concentração do total de sólidos dissolvidos ficou entre 18,37-53,00 mg L-1. Já o ganho de peso final foi de 35,76, 32,95 e 36,25 g para as densidades de 60, 90 e 120 peixes m-3, respectivamente, não sendo verificadas diferenças significativas nos tratamentos avaliados. Os dados do presente estudo abrem precedentes para que cultivo de peixes em canais de irrigação possa ser integrado com outras culturas, maximizando o uso da água.

O presente trabalho teve por objetivo listar as espécies da bacia do rio São Francisco e traçar um perfil de sua ictiofauna, a partir da distribuição dos diversos táxons. Foi realizado a partir de dados da literatura especializada e da identificação de peixes coletados na região de Sobradinho no período de 2002 a 2004 e no Baixo São Francisco nos últimos dois anos. Foram consideradas válidas 244 espécies, das quais 214 são nativas.

Oreochromis niloticus (Nile tilapia) is one of the most produced fish for human consumption globally; however, these fish are susceptible to exposure to toxic chemicals in the water. Pyriproxyfen is a pesticide widely used to control mosquitoes in drinking water supplies and pests in crops. The present study aimed to examine pyriproxyfen's effects on fish O. niloticus fingerlings exposed using an acute 96 h and subchronic tests for 28 days. The lethal concentration LC50-96 h for O. niloticus was 2.77 mg L-1, no observed effect concentration (NOEC), and the lowest observed effect concentration (LOEC) was 1.0 and 2.5 mg L-1, respectively. The hepatic catalase activity was significantly changed after exposure to pyriproxyfen above 0.4 mg L-1. Pyriproxyfen also induced histopathological lesions in the hepatic tissue at 28 days in a dose-dependent pattern at concentrations above 0.4 mg L-1. Pyriproxyfen above 1.2 mg L-1 reduced the locomotor behavior, distance traveled inside the tank, mean speed, and angular variation. This pesticide also decreased weight gain, food conversion, and specific growth rate at concentrations above 1.2 mg L-1. In conclusion, exposure to pyriproxyfen in water from 0.4 mg L-1 may impair O. niloticus development; consequently, pyriproxyfen may affect this fish's production and quality at higher concentrations than commonly used in water (0.01 mg L-1).

This study was conducted to investigate the effects of dietary propolis alcohol extract supplementation on growth performance, digestibility, intestinal morphometry, and physiologic parameters Nile tilápia (Oreochromis niloticus L.) juveniles. For performance experiment and intestinal morphometry, 120 fish averaging 1.41±0.3g were randomly distributed into 24 tanks (70L each) in a closed recirculation water system with constant aeration and biofilter. The animals were distributed into four treatments using a completely randomized design with six replicates per treatment. The treatments consisted of four pellet feeds with different alcohol propolis concentrations extract (AEP) (0.0, 0.5, 1.0 and 1.5gkg-1). The performance experiment period was conducted for 45 days. For the digestibility experiment, an inert marker in the feed and the adapted Guelph feces collecting system were used. The results showed no differences in the performance parameters, crude protein apparent digestibility and dry matter of the feeds, intestinal morphometry, and physiologic parameters. However, there was an increasing linear effect on the energy digestibility with increasing PAE concentrations in the fish feed. The usage of the propolis extract supplementation levels of 1% is recommended for optimum effect on villus morphometry in Nile tilapia.

The aim of this study was to evaluate the influence of different stunning methods on the meat quality of Arapaima gigas fillets from fish farming. A total of 48 specimens of A. gigas in the weight class 11.1 to 14.0 kg were investigated; these fish were subjected to different stunning methods for slaughter: ice asphyxia (IA), air asphyxia (AA), electronarcosis (EE) and hypothermia followed by bleeding (HB). Then, data were obtained from the analysis of pH, rigor mortis index (RI), water activity (Aw), instrumental texture (compression strength, firmness and adhesiveness) and blood glucose and via instrumental colourimetry. During the study, for up to 15 days of refrigerated storage, the methods provided pH values below 6.0. A. gigas submitted to EE and HB remained longer in the pre-rigor status. In addition, they expressed lower percentages of Aw. The EE method resulted in better texture assignments in the fillets. The blood glucose values indicated that the fish subjected to EE were less stressed. Concerning instrumental colourimetry, the fillets submitted to EE and HB showed greater luminosity; the fillets subjected to AA showed greater red-green colour intensity, while the fillets subjected to EE showed greater yellow-blue colour intensity. Therefore, the fish did not suffer stress with electronarcosis, and the fillets showed better preservation, juiciness, and tenderness.
