O Piaractus mesopotamicus é um peixe endêmico da bacia dos rios Paraná-Paraguai, apresentado boa adaptação em sistema intensivo de produção. Nesses sistemas, a amônia pode alcançar níveis extremos quando atividades nutricionais e manejos não são corretas. Neste sentido, o objetivo do presente estudo foi avaliar capacidade tolerância P. expostos diferentes concentrações seu efeito na glicemia co...
A new bariline fish, Barilius kamjongensis is decribed from Kamjong district, the Chindwin basin of Manipur, India. It can be distinguished its congeners in having a body with 2 pairs barbels, 16–19 predorsal scales, 12–15 bars, 40–43 perforated lateral line 7.5/2.5 transverse origin dorsal-fin closed to base caudal-fin, pectoral-fin shorter than head length, depth at 22.8–26.6 % SL, caudal ped...
Skeletal muscle is the edible part of the fish. It grows by hypertrophy and hyperplasia, events regulated by differential expression of myogenic regulatory factors (MRFs). The study of muscle growth mechanisms in fish is very important in fish farming development. Pacu (Piaractus mesopotamicus) is one of the most important food species farmed in Brazil and has been extensively used in Brazilian...
The effects of capture (chasing, netting and air exposure) on cortisol, glucose, chloride, sodium, potassium and calcium concentrations, osmolality, hematocrit, hemoglobin concentration, red blood cells count (RBC) and mean corpuscular volume (MCV) were investigated in pacu (Piaractus mesopotamicus). A total of 132 fish (49.7 +/- 11.7 g) were subjected to capture and 3 minutes air exposure and ...
Innate immune responses are useful to determine the health status of fish and to evaluate the effect of immunomodulatory substances in fish farming. Leukocytes respiratory burst was measured in pacu (Piaractus mesopotamicus) using chemiluminescence assay and nitroblue tetrazolium (NBT) reduction assay. The nitroblue tetrazolium reduction seemed more adequate than chemiluminescence assay for leu...
The objective of this study was to evaluate the methodology to establish the hemolytic activity of alternative complement pathway as an indicator of the innate immunity in Brazilian fish pacu (Piaractus mesopotamicus), in addition to verifying the influence of β-glucan as an immunostimulant. Fish were fed with diets containing 0, 0.1 and 1% β-glucan, during seven days, and then inoculated with ...
