“…These results were in accordance with previous studies that the phytase‐supplemented diets did not affect crude protein, ash or moisture contents in the whole body of gibel carp ( Carassius auratus gibelio Bloch; Liu, Su, & Luo, ) and tilapia ( Oreochromis niloticus ; Adeoye, Jaramillo‐Torres, Fox, Merrifield, & Davies, ). The reason might be that phytase hydrolyses phytate to release phosphorus from phytate‐P, which makes the better utilization of phosphorus in high‐level plant protein diets (Lewandowski et al, ). Coincidentally, ADC of P and productive phosphorus value (PPV) of FM100p was the highest in four treatments ( p < .05) that again confirmed the above view.…”

“…Adding phytase is one of the most common treatment methods in order to increase the bioavailability of phytate-bound phosphorus and improve dry matter and protein digestibility (Biswas et al, 2007;Nwanna, Eisenreich, & Schwarz, 2007). The function of phytase is inducing the dephosphorylation of phytate, leading to the release of myo-inositol molecules and inorganic phosphorus (Lewandowski et al, 2017). With the hydrolysis of phytate, its chelating power declines which makes better absorption of nutrients and phosphorus by the organism, then improving the immunity of fish and promoting the growth of fish (Debnath et al, 2005).…”

A 12‐week growth trial was conducted to evaluate the effect of low fishmeal and phytase replacing inorganic phosphorus on juvenile hybrid sturgeon (Acipenser baeri Brandt ♀ × A. schrenckii Brandt ♂). Four experimental diets were designed as FM100p, FM100, FM250p and FM250, which represented 10% and 25% fishmeal with or without phytase, respectively. The results showed that although growth parameters had no significant difference in all treatments, low fishmeal obviously decreased the culture cost of hybrid sturgeon. Lipid content of body composition was obviously increased in low fishmeal treatments (p < .05). The interaction of low fishmeal and phytase significantly enhanced apparent digestibility coefficients of crude protein (p < .05). Two‐way ANOVA analysis showed that input and output of phosphorus were significantly affected by fishmeal level, phytase and interaction of both factors (p < .05). For the immunological and hepatic function parameters, fishmeal level and phytase had significant effects on the activities of lysozyme, myeloperoxidase, malondialdehyde, alanine aminotransferase, lactate dehydrogenase and alkaline phosphatase (p < .05). The present study potentially justifies that a diet containing 10% fishmeal can be used for hybrid sturgeon. Moreover, replacement of monocalcium phosphate by phytase not only has no adverse effect on the growth of hybrid sturgeon, but also reduces phosphorus emission and protects aquaculture environment.

The jundiá or silver catfish (Rhamdia quelen Quoy & Gaimard, 1824) is species native to the Americas, omnivorous, with a tendency towards carnivorous feeding habits. The species presents commercial potential, and therefore, knowledge on its nutritional requirements, as well as basic feed ingredients, is essential. Its tendency towards carnivorous feeding habits leads to some concerns regarding plant ingredient digestion abilities, although rice, soybean, flax, sorghum, ground corn or oat bran can be used as feed ingredients for this species, since they present good digestibility coefficients. In order to guarantee adequate performance of metabolic, immunological and reproductive functions, jundiá feed can be supplemented with micronutrients that minimize the effects of antinutritional factors present in plant ingredients. Plant ingredients present several economic advantages such as suitable quality, competitive prices and the fact that they are widely available in South Brazil.

“…Amino acid and/or micronutrient supplementation above or below of required level can compromise productive performance and nutrient deposition in the reared fish tissue (WANG et al, 2005;TANG et al, 2013;RAGGI et al, 2016). So, its demonstrates the importance of determining the nutritional requirements of species to formulate nutritionally balanced diets that will provide better use of available nutrients and to reduce the organic matter of the environment in which these animals are being reared (NRC, 2011;LEWANDOWSKI et al, 2017).Many factors can influence the nutritional requirement of a species, including lineage, growth, husbandry, physiological state, physical and chemical parameters of the water, evaluation methods, genetic variations, and especially the type of food used in the formulation of the diet (HU et al, 2008;RAWLES et al, 2013;JIN et al, 2015). These factors influence the results; therefore, biological interpretation is necessary in each case .…”

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.
