“…Shiau and Lan (1996) reported similar observation with feed efficiency for grouper fed different dietary protein diets. This observation is in line with the reports of (Mohanty and Samantaray 1996;Gunasekera et al 2000). Similar trend was also reported by Yang et al (2002) for juvenile silver perch fed graded levels of dietary protein.…”

Fish meal free diets were formulated to contain graded protein levels as 25% (diet 1), 30% (diet 2), 35% (diet 3) and 40% (diet 4). The diets were fed to tambaqui juveniles (Colossoma macropomum) (46.4 ± 6.3g) in randomly designed recirculating systems for 60 days, to determine the optimum protein requirement for the fish. The final weight of the fish, weight gain (28.1, 28.5, 32.2, 28.0g) and specific growth rate increased (P>0.05) consistently with increasing dietary protein up to treatment with 35% protein diet and then showed a declining trend. Feed intake followed the same trend resulting in best feed efficiency (62.5%) in fish fed diet with 35% protein. Similarly, the protein intake increased significantly with increasing dietary protein levels and reduced after the fish fed with 35% protein; while protein efficiency ratio (2.28, 1.99, 1.87, 1.74) decreased with increasing dietary protein levels. Carcass ash and protein had linear relationship with dietary protein levels while the lipid showed a decreasing trend. Ammonia content (0.68, 0.73, 0.81, 1.21 mg L -1 ) of the experimental waters also increased (P<0.05) with increasing protein levels while pH, dissolved oxygen and temperature remained fairly constant without any clear pattern of inclination. Broken-line estimation of the weight gain indicated 30% protein as the optimum requirement for the fish.KEYWORDS: Tambaqui, protein requirement, fish meal free diets Exigência protéica de juvenis de tambaqui, Colossoma macropomum Cuvier, 1818, alimentados com rações livres de farinha de peixe RESUMOForam formuladas quatro dietas sem a inclusão de farinha de peixes contendo os níveis crescentes de proteína de 25% (dieta 1), 30% (dieta 2), 35% (dieta 3) e 40% (dieta 4). As dietas foram fornecidas a juvenis de tambaqui (Colossoma macropomum) (46.4 ± 6.3g) distribuídos ao acaso em um sistema de recirculação durante 60 dias, para determinar o requerimento protéico ótimo para o peixe nesta faixa etária. O peso final dos peixes, o ganho de peso (28.1, 28.5, 32.2, 28.0g) e a taxa de crescimento específico tiveram um aumento não significativo (P>0,05) conforme aumentou o nível protéico das rações até o nível de 35% proteína e então uma tendência ao declínio. O consumo de alimento seguiu a mesma tendência resultando em melhor eficiência alimentar (62.5%) para os peixes alimentados com a dieta contendo 35% de proteína. Similarmente, o consume de proteína aumentou significativamente com o aumento crescente dos níveis protéicos dietários e reduziu após os peixes serem alimentados com a dieta com 35% de proteína, enquanto a taxa de eficiência protéica (2.28, 1.99, 1.87, 1.74) diminuiu com o aumento dos níveis protéicos dietários. A cinza e a proteína da carcaça apresentaram uma relação linear com os níveis protéicos dietários enquanto o lipídio mostrou uma tendência decrescente. O aumento do conteúdo da amônia (0.68, 0.73, 0.81, 1.21 mg L-1) da água dos tanques experimentais com a elevação dos níveis de proteína não foi significativo (P>0,05) enquanto o pH, oxigênio...

“…Fish have high dietary protein requirement (Deng et al 2006). The significance of qualitative and quantitative feeds is well recognized (Jauncey 1982;Mohanty and Samantary 1996;Gunasekera et al 2000;Yang et al 2002;Giri et al 2003;Deepak and Garg 2003;Yang et al 2003;Sales et al 2003;Kalla et al 2004;Islam and Tanaka 2004;Luo et al 2004;Cortes-Jacinto et al 2005;Kim and Lee 2005;Tibbetts et al 2005;Sa et al 2006). Level of dietary protein is of fundamental importance, because it significantly influences growth, survival, and yield of fish as well as economics of a farming industry by determining the feed cost which is typically the largest operational cost.…”

An 8-week growth trial was conducted to assess the effect of dietary protein on growth, feed utilization, protein retention efficiency, and body composition of young Heteropneustes fossilis (10.02 +/- 0.09 g; 9.93 +/- 0.07 cm). Isocaloric (4.15 kcal g(-1), GE) diets with varying levels of protein (25, 30, 35, 40, 45, and 50% of the diet) were fed near to satiation to triplicate groups of fish. Optimum dietary protein was determined by analyzing live weight gain (LWG%), feed conversion ratio (FCR), protein efficiency ratio (PER), specific growth rate (SGR%), and protein retention efficiency (PRE%) data. Maximum LWG% (167), best FCR (1.42), PER (1.75), SGR (1.76), and PRE (31.7%) were evident in fish fed 40% protein diet (Diet 4). Body protein data also supported the above level. However, second-degree polynomial regression analysis of the above data indicated that inclusion of dietary protein in the range of 40-43% is optimum for the growth of young H. fossilis.

“…Gunasekera et al (2000) used five different diets containing 40, 45, 50, 55 and 60% crude protein to culture murray cod, Maccullochella peelii peelii and observed the highest SGR in fish fed with 50% crude protein containing diet. Mohanty and Samantaray (1996) used almost similar diets to culture snakehead, Channa striata and observed the highest SGR in fish fed with 55% crude protein containing diet.…”
