The present study evaluated the assay to quantify respiratory burst activity of blood leukocytes pacu as an indicator innate immune system, using reduction nitroblue tetrazolium (NBT) formazan a measure production reactive oxygen species (ROS). In order assess accuracy assay, fish were challenged by Aeromonas hydrophila and sampled one week after challenge. A. infection increased leukocyte activity. protocol showed reliable easy appropriate determine pacu, neotropical fish, in experimental...
ABSTRACT Feed restriction can be used as a management strategy to increase feed efficiency through compensatory growth (a higher rate after period of restricted feeding). However, there is still lack information on the physiological mechanisms underlying fish responses restriction. Therefore, this study aimed at investigating cycles fasting and refeeding performance, cost feeding, health juvenile tambaqui (Colossoma macropomum). For purpose, feeding protocols were tested for 60 days:...
We evaluated whether body fat content affects the energetic metabolism and growth in pacu submitted to daily feeding, fasting refeeding. For 15 days, fish were fed different diets obtain lean conditions, then subjected, for 20 days to: (1) continuously feeding (control), or (2) refeeding 5 days. Blood (glucose, triglycerides, cholesterol, non-esterified fatty acids total protein) tissue (liver lipid glycogen, muscle mesenteric fat) metabolic indicators, performance parameters (weight gain,...
We evaluated growth performance and metabolic responses in Nile tilapia (Oreochromic niloticus) juveniles (30.2 ± 0.9 g) subjected to 1 (F1), 2 (F2), or 3 weeks (F3) of fasting then refed for 10 (10WR) compared controls (FC), which were fed the full 13-week trial. Weight gain specific rate (SGR) during lower all treatments FC. However, refeeding, feed intake/body mass SGR increased F1, F2, F3, inducing partial compensatory growth. The hepatosomatic index (HSI), visceral fat (VFI), liver...
O objetivo deste estudo foi avaliar a ocorrência de resposta compensatória no desempenho produtivo juvenis tilápia do Nilo Oreochromis niloticus, linhagem GIFT, submetidos diferentes estratégias alimentares. Foram utilizados 135 tilápia, distribuídos em nove tanques polietileno 100L cada. As testadas foram: grupo controle (alimentado todo dia), alimentado por cinco dias seguidos dois restrição alimento (5A/2R) e quatro três (4A/3R). avaliados parâmetros físico-químicos da água produtivo. Os...
Immunostimulants, such as β-glucans are an efficient alternative to the use of antibiotics in aquaculture. However, it is important determine ideal route administration for a better stimulation fish immune system. Thus, this study evaluated different routes β-glucan (oral, injection, immersion) on hematology and response. After 15 days injection/bath/feeding, blood was sampled hematological immunological parameters. Differential leukocyte count affected (p<0.05) by treatments. Neutrophil...
Inulin is a prebiotic that plays an important role in improving health and immunity humans, animals fish. We tested whether inulin supplementation would improve the immune protection of juvenile pacu (Piaractus mesopotamicus) exposed to capture transfer tanks followed by bacterial inoculation. For this, we fed fish for 15 days with diets supplemented 0.5% or 1.0% evaluated levels plasma cortisol, glucose chloride; leucocyte respiratory activity (RAL); serum lysozyme; haematological...
ABSTRACT This study aimed evaluate energetic mobilization in tambaqui submitted to fasting, after a one-day refeeding. 120 juveniles were distributed 12 310L polyethylene boxes. Three treatments evaluated: Control (14 days of feeding); Fasting for 14 days; and Refeeding (13 fasting one day feedback). After the experimental period, fish anesthetized with eugenol blood collection serum plasma used measure glucose, triglycerides, cholesterol protein. Subsequently, euthanized remove liver...
A 52-day experiment was conducted to determine the crude protein (CP) requirements of juvenile matrinx&atilde; Brycon amazonicus, and evaluate their resulting growth performance, hematological parameters enzymatic activities. Sixty fish (29.03g &plusmn; 1.16g) were distributed in 12 tanks (310 L) with a completely randomized design, maintained at four dietary levels (270, 320, 350, 390 g.kg-1) for 52 days. The results revealed that fed diet g.kg-1 CP had best final weight, weight...
