This study was conducted to evaluate the effects of different diet energy levels on animal performance. Specifically, this investigation examined the reproductive and histological aspects of the liver and gonads of female silver catfish (Rhamdia quelen). These fish were fed for 210 days with diets containing 30% digestible protein (DP) and digestible energy (DE) that corresponded to 11.93, 12.98, 14.03, 15.07 and 16.12 MJ of DE kg−1. The initial and final lengths, weights, and weight gains, the visceral, gonadal, and hepatosomatic indices, and the histological parameters hepatocytes area and gonadal stages were evaluated. In the reproductive season, the fish were submitted to an artificial reproduction protocol and the percentage of spawning females and their relative and absolute fecundity were evaluated. DE did not affect reproductive or animal performance aspects (P > 0.05). Cytoplasmic vacuoles in hepatocytes were observed in higher DE levels. Thus, female Rhamdia quelen can be fed a diet of 30% DP with 11.93 MJ of DE kg−1 without reproductive or performance losses.

“…This lack of information about the specific broodstock nutritional requirements in fish (Bhujel et al, 2001;Lupatsch et al, 2010) has driven the recent development in research studies on both tilapia (El-Gamal et al, 2007;Sink & Lochman, 2008;Sink et al, 2010;Ng & Wang, 2011) and other commercial freshwater (Parra et al, 2008;Navarro et al, 2010) and marine (FernandezPalacios et al, 1995;Mazzorra et al, 2003) fish cultures.…”

-This study was carried out to evaluate the influence of different levels of digestible energy and digestible protein in diets of Nile tilapia (Oreochromis niloticus) broodstock on offspring growth during sex reversal stage. A total of 2,700 post-larvae (8.2±0.001 mg) derived from breeders fed nine diets with distinct levels of digestible protein (28, 34 and 40% DP) and digestible energy (2,800; 3,400; and 4,000 kcal DE.kg -1 ) were stored in twenty-seven 70 L tanks. After 30 days of growth, their average final weight (AFW, g), average weight gain (AWG, g), final standard length (SL, cm), condition factor (CF), specific growth rate (SGR, %/day), stock uniformity (UNI, %), survival (SUR, %) and sex reversal rate (SRR, %) were measured. Although female nutrition is thought to influence the performance or quality of progeny during early life stages, no influence of diets supplied to broodstock was detected on any parameter. Nonetheless, the offspring presented commercially satisfactory growth rates. Thus, diets containing 28% of digestible protein and 2,800 kcal of digestible energy.kg of diet -1 can be used to feed Nile tilapia broodstock without jeopardizing offspring performance during the sex reversal phase.

Tilapia is one of the most bred species in Brazil because it is resistant to viral, bacterial and parasitic diseases when compared to other cultivated fish. Knowledge about the blood components and their function is important for normal and pathological balance. Different oil sources used to feed breeding males of Nile tilapia (Oreochromis niloticus) were evaluated on the hematological parameters. In the experiment, we used 80 male tilapias, 20 males for each treatment. The experiment was a completely randomized design with 4 treatments and four repetitions, which used a 32% CP diet and isoproteic isoenergetic 3,300 kcal DE kg-1 each implemented with a different oil source T1: linseed oil (OL), T2: soy oil (SO), T3: fish oil (OF) and T4: corn oil (CO).The feeding management consisted on two daily feeding at 8 am and 4 pm, in the amount of 3% body weight. The diet intake was 232.2 g/day. No significant difference was detected for the percentage of red cells, mean corpuscular volume, hematocrit, and mean leukocyte percentage. However, for the mean corpuscular hemoglobin concentration (CHCM) and hemoglobin, fish fed soybean oil presented significantly higher values than other treatments. The soybean oil, characterized by iron with a high bioavailability, led to higher levels of hemoglobin and CHCM in Nile tilapia, which possibly can reflect a greater oxygenation in fish. However, the fish oil originated greater values of both components of the blood (hematocrit, red cells) and immune (thrombocytes, monocytes, neutrophils and lymphocytes) system.
