“…Lipids showed the highest and lowest values (P < 0.05) at 50 g kg À1 and 100 g kg À1 glycerol, respectively. Graeff & Tomazelli (2007) also observed similar results with young carp. The ash contents did not show significant differences between the treatments also.…”

The present study evaluated the effects of inclusion of glycerol in the diet of Nile tilapia juveniles on growth performance, biochemical changes in blood, and carcass composition. We used 300 Nile tilapia juveniles with an average initial weight of 29.15 ± 8.40 g and 11.55 ± 0.87 cm in length, distributed in 20 fiberglass tanks with a capacity of 250 L. The experiments followed a completely randomized design with five treatments and four replications during 79 days. The animals were fed diets containing four concentrations of glycerol (25 g kg À1 , 50 g kg À1 , 75 g kg À1 and 100 g kg À1 ) and a control diet without glycerol. HDL was the only biochemical parameter, that showed statistically different (P < 0.05) results; it was higher in the groups fed with 0 and 75 g kg À1 glycerol compared to the other groups. No significant difference was observed in the results from the carcass composition of tilapia juvenile fed with the different glycerol levels, except for lipids (P < 0.05), which showed the highest values in fish fed with 50 g kg À1 glycerol and the lowest in fish fed with 100 g kg À1 . Glycerol can be used in fish diets as an energy supplement without causing damage to growth performance or to the biochemical and carcass composition of Nile Tilapia juveniles.

“…One of the greatest requirements for fish rations is with regard to available energy for maintenance, growth, or reproduction, because the dietary energy source for these animals comes from proteins, lipids, and carbohydrates (Graeff & Tomazelli 2007).…”

“…The absence of any tendency towards better results for any of the oil sources tested (Table 2) strengthens this hypothesis. Similar results were observed for the Nile tilapia (Matsushita et al, 2006), jundiá Rhamdia quelen (Losekann et al, 2008) and common carp Cyprinus carpio L. (Graeff and Tomazelli, 2007). The use of oils rich in n-3 highly unsaturated fatty acids (HUFA) has allowed improvements on the growth of juvenile Japanese sole (Paralichthys olivaceus) fed with a diet supplemented with squid liver oil (Kim et al, 2002).…”

The influence of fatty acid composition of the diets on the productive performance and on cold and heat tolerance of juvenile freshwater angelfish (Pterophyllum scalare), in three different phases, was studied. Phase I studied the productive performance of freshwater angelfish in a completely randomized experimental design with four treatments, canola, linseed, olive and soybean oils and four replicates during 50 days using 192 fish in 16 aquaria. Phase II studied the cold tolerance of juvenile freshwater angelfish using 72 juvenile freshwater angelfish, coming from phase I and maintained in 12 aquaria climatized chamber. The temperature was reduced 1 °C per day, until the observation of 100% fish mortality. Phase III, it was studied the heat tolerance of juvenile freshwater angelfish employing an identical procedure to phase II, but with a daily increase of 1°C. Significant differences (P>0.05) were not observed for any parameters evaluated. Thus, it was concluded that the type of vegetable oil (canola, linseed, olive and soybean) used as a diet supplement did not affect the productive performance, nor the tolerance to cold and heat, of juvenile freshwater angelfish.

“…The common carp is considered a species with great potential in fish farming due to its tolerance to low levels of dissolved oxygen, handling, and wide temperature range; easy reproduction; good adaptation to farming systems; and good acceptance of a variety of diets (BARBIERI et al, 1998;OMAR et al, 2012;TANG et al, 2013). Although its meat is not the most sought after by the food industry, the demand for its by-products and processed meats is increasing (GRAEFF and TOMAZELLI, 2007).…”

O presente estudo teve por objetivo determinar a exigência de lisina para alevinos de carpa comum (Cyprinus carpio). Foram distribuídos inteiramente ao acaso 280 alevinos de carpa comum com peso e comprimento inicial médio de 0,62 ± 0,05 g e 3,38 ± 0,11 cm, respectivamente, em 28 tanques-rede quadrados com volume útil de 150 litros, dispostos no interior de um tanque circular de alvenaria com capacidade para 25 m 3 de água (sete tratamentos e quatro repetições). Os peixes foram alimentados até a saciedade aparente quatro vezes ao dia com dietas isproteicas e isoenergéticas suplementadas com lisina nas concentrações de 1,58; 1,81; 2,05; 2,29; 2,53; 2,76 e 3,0% da dieta por 57 dias. Ao final do estudo foi avaliado o desempenho produtivo, sobrevivência e composição centesimal da carcaça dos peixes. Os dados obtidos foram submetidos a análise de regressão (p<0,05) e ao teste múltiplo de média Tukey. A análise do platô de resposta linear (LRP) foi aplicado adicionalmente. A suplementação de lisina melhorou (p<0,05) o peso final médio, ganho de peso médio e taxa de crescimento específico e a partir de 2,29% de suplementação de lisina na dieta prejudicou a eficiência alimentar dos peixes. A exigência de lisina para alevinos de carpa comum é de 1,89% da dieta ou 4,73% da proteína bruta para obtenção do melhor crescimento.Palavras-chave: aminoácidos; nutrientes; exigências; ração. ABSTRACTThe aim of the present study was to determine the lysine requirement of common carp fingerlings. Two hundred and eighty common carp fingerlings, with mean weight and mean length initial of 0.62 ± 0.05 g and 3.38 ± 0.11 cm, respectively were randomly distributed into 28 squares net cages of 150 litres arranged inside a masonry circular tank with water capacity of 25 m -3 (seven treatments and four replications). The fish were fed until apparent satiation, four times per day, with isoproteic and isoenergetic diets supplemented with lysine at 1.58, 1.81, 2.05, 2.29, 2.53, 2.76, and 3.0% of the diet for 57 days. Productive performance, survival rate, and chemical composition of the fish body were evaluated at the end of the study. The data obtained was subjected to regression analysis and, when significantly different (P<0.05), the Tukey multiple comparison test was used. Additionally, linear response plateau (LRP) analysis was performed. Lysine supplementation significantly improved (P<0.05) mean final weight, mean weight gain, and specific growth rate. However, lysine levels above 2.29% compromised the feed efficiency. Lysine requirements of common carp fingerlings were found to be 1.89% of the diet or 4.73% of the crude protein in the diet for obtain better growth.
