“…Vielma et al (2000) desenvolveram estudo para avaliar a influência da substituição parcial da farinha de peixe por derivado da soja em rações para truta arco-íris adulta com dois níveis de fitase (0 e 1.200 uf/kg) e verificaram que uma parte significativa da farinha de peixe pode ser substituída por proteínas da soja sem comprometer o ganho de peso ou a eficiência alimentar. Furuya et al (2001) avaliaram os efeitos da adição de diferentes níveis de fitase (0, 500, 1.500 e 3.000 uf/kg) em dietas contendo 4% de farinha de peixe, 1,8% de calcário calcítico e ingredientes de origem vegetal para tilápias-do-nilo durante 45 dias e concluíram que a utilização de ração com 700 uf/kg foi adequada para o desempenho produtivo na fase inicial.…”

This research was carried out to compare the effect of phytase on performance, in the incorporation and excretion phosphorus in Nile tilápia. Four diets were used: one standard (contol), composed by 3,200 DE kcal ED/kg of ration and 30.0% CP and supplemented with phosphorus (4.0% of dicalcium phosphate), considering the treatment control, and others three, without phosphorus supplementation, with different phytase levels (1,000, 1,500, and 2,000 uf/kg), with four replication, per a period of 82 days. Circular tanks of fiber glass, with constant flow and aeration were used. The results demonstrated that the use of phytase in diets for fish production can reduce the levels of inorganic phosphorus in the diets and minimizing the impacts caused by phosphorus in the production system and in the natural environment and also can improve the productivity, increasing the amount of feed to be supplied and, consequently, facilitating the increase of biomass of fish to be used per production area.

“…To determine the mineral retention of scales, three animals from each replicate were peeled by scraping with a scalpel blade and the scales were dried at 50 °C. The spinal bones were kept in warm water (80 °C) for two minutes and then immediately dissected with tweezers (Furuya et al, 2001). These samples were digested in acid solution (Silva and Queiroz, 2004) and the concentrations of P and Ca were determined in triplicate through atomic absorption spectrophotometry (Tedesco et al, 1995).…”

Dietary phosphorus requirement of pejerrey fingerlings (Odontesthes bonariensis)

-To determine the available phosphorus requirement of pejerrey fish, four semi-purified diets were formulated to contain increasing available phosphorus levels (0.90, 2.7, 5.7 and 8.3 g/kg). Each diet was assigned to groups of 10 fish with average weight of 1.26±0.17 g, distributed into a completely randomized design with four treatments and four replications. Fish were fed at a rate of 10% total biomass four times a day for 60 days. The parameters productive performance, body chemical composition and mineral composition of bones and scales were evaluated. The best productive performance of fingerlings was obtained with the diet containing 4.3 g/kg available phosphorus. The average level of 6.3 g/kg available phosphorus promotes better mineralization of bones and scales in pejerrey fish.

RESUMO -Objetivou-se determinar a exigência de fósforo disponível para tilápias-do-nilo. Utilizaram-se 144 peixes com peso vivo inicial de 35,33 ± 0,66 g, distribuídos em delineamento de blocos ao acaso, com quatro tratamentos e três repetições. Foram fornecidas dietas com 29,0% PB, 2.980 kcal/kg de energia digestível (ED) e quatro níveis de fósforo disponível (0,25; 0,35; 0,45 ou 0,55%), obtidos pela utilização de fosfato bicálcico como fonte de fósforo. As dietas foram fornecidas aos peixes três vezes por dia, até aparente saciedade, durante 46 dias. Não foi observado efeito dos níveis de fósforo disponível na dieta sobre o índice hepatossomático, a taxa de sobrevivência e os teores de água e proteína bruta na carcaça.O aumento dos níveis de fósforo disponível na dieta promoveu aumento linear do ganho de peso médio, da excreção de fósforo e dos teores de cinza na carcaça e de cinzas, cálcio e fósforo nos ossos. Houve efeito quadrático dos níveis de fósforo disponível sobre o consumo de ração, a conversão alimentar e a taxa de eficiência protéica, que foram melhores nos níveis 0,37; 0,48 e 0,48% de fósforo disponível, respectivamente. A exigência de fósforo disponível para tilápia-do-nilo de 35 a 100 g é de 0,48% (0,53% na matéria seca).

A total of 144 fishes with initial weight 35.33 ± 0,66g LW were distributed to a completely randomized blocks design, with four treatments and three replicates. Diets with 29.0% CP and 2980 kcal/kg DE and four available phosphorus levels (0.25; 0.35; 0.45 e 0.55%) were used. The dicalcium phosphate was used as phosphorus source. The diets were fed to the fishes three times a day to apparent satiation, during 46 days. No significant effect of dietary available phosphorus on hepatosomatic index, survival rate and carcass water and protein contents were observed. The increase of available phosphorus levels in the diet promoted linear increase of average weight gain and phosphorus excretion, and content of ash in carcass and ashes, calcium.There was a quadratic effect of dietary available phosphorus on feed intake, feed conversion ratio and protein efficiency ratio and the best values were obtained with 0.37, 0.48 and 0.48%, respectively. Dietary requirement of available phosphorus for Nile tilapia from 35 to 100 g is 0.48% (0.53% DM).
