| O jundiá, Rhamdia quelen, é uma espécie de peixe nativa ainda pouco conhecida cientificamente, mas que tem atraído a atenção de produtores e pesquisadores devido a várias características favoráveis à sua inclusão na lista de peixes criados comercialmente no país. A freqüência alimentar é um fator importante dentro do manejo em piscicultura visando melhorar a eficiência produtiva e reduzir os custos de produção. O presente trabalho testou quatro regimes de arraçoamento (1, 2, 3 e 4 vezes ao dia) em intervalos regulares. Alevinos de jundiá (1,88g) foram estocados em 12 tanques de 4m² por 65 dias. A temperatura da água variou de 23 a 27ºC, durante o período experimental, e os peixes de todos os tratamentos apresentaram índices zootécnicos de desempenho (ganho... |

| The addition of salt to the water has been used to mitigate stress and improve survival in fishes. This study investigated the effects of sodium chloride (0.0, 1.0, 3.0 and 6.0 g/l) on levels of plasma cortisol, glucose, tryacilglycerol, total protein, hematocrit, hemoglobin, erythrocyte number, liver glycogen and lipid, and muscle lipid in adult matrinxã(Brycon amazonicum) after a 4-h transport and during a 96-h recovery period. Fish were sampled before and after transport, and 24 and 96 h of the recovery period. Plasma cortisol was higher than initial condition immediately after transportation, except in fish transported in 3.0 and 6.0 g/l of salt. A similar pattern was observed for blood glucose but fish transported in water with 0.0, 1.0 and 3.0 g/l of... |

| Abstract: The objective of this work was to evaluate the effect of dietary arginine concentrations on the health status of Nile tilapia (Oreochromis niloticus) cultivated in cages. The experiment was carried out in a completely randomized design with four treatments (2.3, 2.9, 3.5, and 4.1% arginine in dry matter) and three replicates, in 12 net cages of 8 m3, containing 4,000 sexually reverted tilapia (63±20 g, at 500 fish m-3). Fish productive performance and health were evaluated. Biochemical, hematological, and immunological parameters, as well as the morphological aspects of gills and liver, were evaluated. Arginine inclusion did not cause significant differences in fish growth performance. However, arginine supplementation at 3.5% concentration... |

| Fish transportation is a common practice on fish farms and is considered to be a stressor that could negatively affect fish health. The objective of this study was to evaluate several physiological responses of stress in jundiá caused by transport at different loading densities. Jundiá juveniles were placed in plastic bags on a mechanical transport simulator for four hours at four different loading densities (75, 150, 250 and 350 g L-1) and then transferred to sixteen 80-L plastic boxes for 96 hours after transport. Water samples were collected before and after transport to measure dissolved oxygen, temperature, pH and ammonia levels. Blood samples were taken at departure and arrival, as well as at 24 and 96 hours after transport to monitor cortisol,... |

| O objetivo deste trabalho foi testar a eficiência de tratamentos convencionais no controle da infestação do ictio no jundiá (Rhamdia quelen). Vinte alevinos (3-6 cm) foram estocados em 28 aquários (10 L) durante 192 horas e submetidos aos seguintes tratamentos: controle, formalina comercial (0,2 mL L-1), permanganato de potássio (1,3 mg L-1), sulfato de cobre (0,63 mg L-1), sal comum (10 g L-1), verde de malaquita (0,05 mg L-1) e elevação da temperatura para 32°C. O sulfato de cobre, o sal e a elevação da temperatura reduziram o número de parasitas ao final do experimento, podendo ser utilizados como substitutos do verde de malaquita no controle do ictio no jundiá. |
