The objective of this study was to use the residues of fermented sardine to elaborate the acid fish silage and its use in feed for aquaculture. Biological assay was performed by feeding largemouth bass (Micropterus salmoides) fingerlings (initial weight 22g), with extruded diets (41% crude protein; 3,600 kcal/kg digestible energy) containing 0.0, 7.5, 10.0, 12.5, or 15.0% of fish silage in partial substitution to the fish meal. The feed conversion ratio and weight gain for the treatments were: 1.26 and 15.76g; 1.11 and 17.07g; 1.19 and 17.81g; 1.18 and 19.83g; 1.47 and 14.64g, respectively. No significant differences (P<0.05) were detected among the treatments. Results indicated that it was possible to use up to 15% of acid fish silage as partial... |

One of the most important problems involving treatments with antibiotics against Aeromonas hydrophila isolated from fishes is that antibiotic resistance develops readily. The antimicrobial activity of chemotherapeutants in isolates from pacu Piaractus mesopotamicus (Holmberg, 1887) and tilapia Oreochromis niloticus (Linnaeus, 1758) was tested by the Kirby-Bauer disk method, over Mueller-Hinton surface agar previously inoculated with 100 µL of bacterial suspensions. After regular incubation, isolates from tilapia and pacu were uniformly resistant to amoxicillin, ampicillin, lincomycin, novobiocin, oxacillin, penicillin, and trimetoprim+sulfametoxazole. The A. hydrophila type strain presented resistance to the same antimicrobial substances and also against... |

The objective of this work was to evaluate corn gluten meal (CGM) as a substitute for fish meal in diets for striped catfish (Pseudoplatystoma fasciatum) juveniles. Eight isonitrogenous (46% crude protein) and isoenergetic (3,450 kcal kg-1 digestible energy) diets, with increasing levels of CGM - 0, 6, 12, 18, 24, 30, 36, and 42% -, were fed to juvenile striped catfish (113.56±5.10 g) for seven weeks. Maximum values for weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio, evaluated by polynomial quadratic regression, were observed with 10.4, 11.4, 15.4 and 15% of CGM inclusion, respectively. Feed intake decreased significantly from 0.8% CGM. Mesenteric fat index and body gross energy decreased linearly with increasing... |

Alevinos de tilápia nilótica Oreochromis niloticus (L.) com peso médio de 18,85 g, foram estocados em gaiolas de 1,7 m3 cada, em densidades de 75, 150, 300 e 600 peixes/m3 (T75; T150; T300 e T600), num delineamento inteiramente casualizado (4 tratamentos e 3 repetições), e criados por 196 dias, com ração comercial extrusada, flutuante, contendo 28% de proteína bruta. A cada 30 dias, 20% do lote de peixes de cada gaiola foi medido e pesado para determinar ganho de peso (GDP) e conversão alimentar (CA) de cada tratamento. Os resultados finais de CA e GDP para cada tratamento foram, respectivamente: para T75, 6,31:1 e 71,52g; para T150, 4,08:1 e 65.14g; para T300, 3,57:1 e 59,60g; e para T600, 2,96:1 e 69,17g. Em relação ao ganho de peso, T600 e T75 foram... |

O objetivo deste trabalho foi avaliar tempo de passagem do alimento e seqüência de repleção e depleção dos órgãos no trato gastrintestinal de Salminus brasiliensis. Cem peixes (38,8±7,6 g) foram mantidos em 20 gaiolas (60 L), a 24,8±0,2ºC e alimentados com ração contendo 1% de Cr2O3. A cada 60 min a partir da primeira alimentação foram sacrificados cinco peixes e foi verificada a localização da digesta no trato gastrintestinal. A partir da segunda hora depois da alimentação, observou-se redução gradativa do conteúdo estomacal e subseqüente presença de digesta no intestino. Esse padrão se mantém até a 16ª hora; uma e duas horas depois, estômagos e intestinos, respectivamente, encontram-se completamente vazios. |

Dietary vitamin supplementation decrease stress caused by high stocking density, and boosts immunological system of farmed fish. A studied was carried out to determine vitamin A requirements of Nile tilapia (Oreochromis niloticus) in an all male group (13.8 ± 1.2 g) and a mixed sex population (9.8 ± 2.3 g). Fish stocked in 100-L plastic aquaria (26.0 ± 1.0ºC) were fed to near satiety, twice a day, seven days a week, during 75 days with vitamin A-free, semi-purified diets supplemented with 0; 600; 1,200; 1,800; 2,400; 3,000; 3,600; 4,200; 4,800 and 5,400 International Units (IU) of retinyl palmitate (30% vitamin A) per kg of diet in a completely randomized experimental design, factorial arrangement 2c10 (n = 4). Deficiency signs of vitamin A were observed... |

ABSTRACT Cost and environmental restrictions limit the use of fishmeal (FM) in aquafeeds and plant protein (PP) sources. Soybean by-products are important alternative; however, their antinutritional factors may reduce fish growth. This study evaluates the effect of FM substitution for PP (soybean meal and soy protein concentrate) in diets of dourado (Salminus brasiliensis), a promising species for fish farming and empirically considered highly tolerant to PP-based diets. A control diet was formulated to contain 20 % of fishmeal and 61 % of plant protein (SBM) and other five diets with decreasing FM graded levels (16 %, 12 %, 8 %, 4 %, 0 %), which were replaced by soybean protein concentrate (SPC), comprising six treatments and four replicates. Fifteen... |

O objetivo deste trabalho foi avaliar alterações nas formas de reserva de energia na carcaça de juvenis de "black bass" (14,46 ± 0,81 g de peso vivo). Peixes condicionados a aceitar alimento artificial foram estocados em 90 gaiolas de volume 60 L alojadas em caixas de 1.000 L em laboratório com condições ambientais controladas, e alimentados por 64 dias com rações extrusadas com níveis de proteína variando entre 34 e 54% (incrementos de 4%) e teores de energia digestível variando de 3.600 a 4.100 kcal kg-1 de alimento (incrementos de 125 kcal kg-1). Foram analisados as variáveis de ganho de peso, consumo alimentar diário, relação hepato-somática, relação víscero-somática, deposição protéica e energética, glicogênio tecidual hepático e lipídio visceral. Não... |

The objective of this work was to determine the dietary lysine (DL) and dietary arginine (DA) requirements of dourado (Salminus brasiliensis), through dose-response trials using the amino acid profiles of whole carcasses as a reference. Two experiments were carried out in a completely randomized design (n=4). In the first experiment, groups of 12 feed-conditioned dourado juveniles (11.4±0.2 g) were stocked in 60 L cages placed in 300 L plastic indoor tanks in a closed circulation system. Fish were fed for 60 days on diets containing 1.0, 1.5, 2.0, 2.5, 3.0, or 3.5 % dietary lysine. In the second experiment, dourado juveniles (27.0±0.8 g) were fed for 60 days on semipurified diets containing arginine at 1.0, 1.5, 2.0, 2.5 or 3.0%, in similar conditions to... |

ABSTRACT: The dourado, Salminus brasiliensis, a large, carnivorous, Neotropical, Characin, is highly regarded for fish farming and sport fishing alike. However, studies on the farming and husbandry of dourado are still scarce. This study evaluated the performance of dourado fed diets formulated so as to contain increasing levels of poultry by-product meal as a replacement for fish meal and aimed to identify the maximum level of replacement to maximize profit. The trial was set up in a closed recirculation system with controlled water quality (temperature 27 °C, dissolved oxygen 6.5 mg L−1, pH 7.4, and ammonia 0.25 mg L−1). Juvenile fish were stocked in tanks in a completely randomized design, acclimatized to system conditions and experimental diets, and... |

O experimento teve como objetivo avaliar a influência da suplementação de vitamina C na dieta sobre o desempenho de alevinos de piauçu (Leporinus obtusidens). Um primeiro ensaio (105 dias) testou o efeito da suplementação de níveis crescentes de L-ácido ascórbico (0, 50, 150, 250, 350, 450, 550, 650, 750 e 850 mg/kg) na dieta sobre ganho de peso e sobrevivência, num delineamento inteiramente ao acaso. Não houve diferenças significativas (P > 0,4054) entre os tratamentos, tanto para ganho de peso como sobrevivência. Num segundo ensaio avaliou-se a influência da vitamina C na resistência dos alevinos à hipoxia. Grupos de dez peixes aleatoriamente selecionados de cada tratamento do primeiro ensaio foram estocados em gaiolas, num delineamento em blocos ao... |
