“…Closer protein requirement values (42.53% CP) to this study were observed for Goldfish with 1.66 g live weight fed diets with different crude protein concentration formulated with several locally available agro-products (BANDYOPADHYAY, SWAIN;MISHRA, 2005). Conversely, Lochman and Phillips (1994) reported a lower protein requirement (29.0% CP) when fed Goldfish with semipurified diets containing increasing levels of crude protein.…”

The optimal dietary digestible protein to energy ratio is critical for the success of fish farming. Considering that it provides the proper development of the animals, this study was undertaken to evaluate the effects of different dietary digestible protein to energy ratio in diets for goldfish fingerlings. Diets were formulated to contain 28.0, 35.0, 42.0 and 49.0% DP and 3,600 and 3,200 kcal/ kg. The growth parameters evaluated were daily weight gain (DWG), feed intake (FI), feed conversion ratio (FCR), protein efficiency ratio (PER), protein productive value (PPV) and energy retention ratio (ERR) and specific growth rate (SGR). Regardless FI, all the parameters were affected by protein and energy levels and interaction between both factors was observed. The second-order polynomial equation best fitted to the DWG, SGR, FCR, PER and ERR with estimated requirement values of 38.81, 38.85, 41.05, 41.80 and 39.39% DP, respectively, at the 3,200 kcal/kg. A second-order polynomial model was significant only for the ERR data at the 3,600 kcal/kg with an estimated requirement value of 36.45% DP. Generally, fish fed diets containing 3,200 kcal/kg had better growth performance than fish fed 3,600 kcal/kg (P<0.01), indicating a higher feed efficiency. A 3,200 kcal/kg diet seems to be the proper DE level for meeting goldfish requirement for highest weight gain. Based on this experimental condition, we recommend the use of DP levels between 38.0-40.0% in diets for goldfish with 3,200 kcal/kg or a dietary protein to energy ratio between 119-125 mg/ kcal DE.Index terms: Energy requirement, feed intake, growth protein requirement, ornamental fish. RESUMOA ótima relação energia/proteína é importante para o sucesso da piscicultura. Considerando que a mesma fornece o adequado desenvolvimento dos animais, este estudo foi realizado para avaliar a relação energia/proteína digestível ótima para alevinos de kinguio. Dietas foram formuladas para conter 28,0; 35,0; 42,0 e 49,0% PD e 3600 e 3200 kcal/kg. Foram avaliados: ganho de peso diário (GPD), consumo de ração aparente (CRA), conversão alimentar aparente (CAA), taxa de eficiência protéica (TEP), valor produtivo protéico (VPP), taxa de retenção de energia (TRE) e taxa de crescimento especifico (TCE). Com exceção do CRA, todos os parâmetros foram afetados pelos níveis de proteína e energia e interação entre os dois fatores foram observados. O modelo que melhor se ajustou aos parâmetros GPD, TCE, CAA, TEP e TRE foi o polinomial de segunda ordem com valores de exigência de 38,81; 38,85; 41,05; 41,80 e 39,39% DP, respectivamente, para o nível de 3200 kcal ED/kg. O modelo polinomial de segunda ordem foi significativo apenas para os dados de TRE no nível de 3600 kcal ED/kg, com valor de exigência 36,45% PD. Os peixes alimentados com dietas contendo 3200 kcal/kg apresentaram melhor desempenho de crescimento do que os alimentados com 3600 kcal/kg (P<0,01), indicando uma maior eficiência alimentar. 3200 kcal/kg ED parece ser o nível adequado encontrado para kinguio para maior ganho d...

SUMMARYThe efficiency of a recirculation system for the cultivation of C. auratus, fed with natural and artificial diets was evaluated. The experiment consisted of four treatments with four replicates. The first two treatments used recirculation system and the last two static system. In the first and fourth treatment, animals were fed with brine shrimp biomass (50% CP), while in the second and third treatments a commercial flake ration (42% CP) was used. At the end of cultivation (60 days), water samples were taken from all experimental units and subjected to standard plate count for determining the density of mesophilic bacteria. Final weight (g), final length (cm), specific growth rate (% day -1 ) and weight gain (%) were significantly different (p<0.05) among tested diets, but the culture systems did not affect fish performance. There was significant difference (p<0.05) between systems for total ammonia and nitrite. Animals fed with brine shrimp biomass acquired more intense and brighter colors than those fed only with commercial flake food. The values of standard plate count of mesophilic bacteria ranged from 7.0 × 10 3 to 1.1 × 10 4 CFU.ml -1 . In this study we observed that C. auratus is a species tolerant to adverse water conditions, perhaps with increased stock densities, the recirculation system could play some positive role on the zootechnical performance of cultured animals. RESUMOA eficiência de um sistema de recirculação para o cultivo de C. auratus, alimentados com dieta natural e artificial foi avaliada. O experimento consistiu de quatro tratamentos com quatro repetições. Os dois primeiros tratamentos utilizaram sistemas de recirculação e os dois últimos sistemas estáticos. No primeiro e quarto tratamento, os animais foram alimentados com biomassa de artêmia (PB 50%), enquanto nos tratamentos dois e três, com ração comercial em flocos (42% PB). Ao final do cultivo (60 dias), amostras de água foram coletadas em todas as unidades experimentais e submetidos a contagem padrão em placas para determinação da densidade de bactérias mesófilas. O peso final (g), comprimento final (cm), taxa de crescimento especí-fico (% dia -1 ) e ganho de peso (%) foram significativamente diferentes (p<0,05) entre as dietas testadas, mas os sistemas de cultivo não afetaram o desempenho dos peixes. Houve diferença significativa (p<0,05) entre os sistemas para os níveis de amônia total e nitrito. Os animais alimentados com biomassa artêmia adquiriram cor e brilho mais intensos do que aqueles alimentados apenas com ração comercial em flocos. Os valores de contagem padrão em placas de bactérias mesófilas variaram de 7,0 × 10 3 para 1,1 × 10 4 CFU.ml -1 . Neste estudo, observou-se que C. auratus é uma espécie tolerante a condições adversas de água, talvez com maior densidade de estocagem, o sistema de recirculação poderia desempenhar papel positivo sobre o desempenho zootécnico dos animais cultivados.

“…Los grupo amino que no son reutilizados en la síntesis de aminoácidos, deben ser excretados para evitar su acumulación en el plasma sanguíneo y en los tejidos del organismo (Wilkie, 2002;Randall, 2011). La mayoría de peces teleósteos son amoniotélicos, puesto que el exceso de nitrógeno liberado durante la desaminación es excretado en forma de NH 3 (principal producto excretado y producto final del catabolismo proteico). Los organismos amoniotélicos utilizan esta estrategia principalmente por dos factores: primero porque tiene un menor costo energético, puesto que no convierten el amonio a urea y ácido úrico (Altinok y Grizzle, 2004); y segundo porque el NH 3 puede difundirse fácilmente a través de la membrana branquial, debido a su solubilidad en lípidos y a su falta de carga (Sinha et al, 2012).…”

RESUMENPara el diseño de los sistemas cerrados de recirculación (SCR) y sistemas acuapónicos (SA) es importante conocer la tasa de excreción de nitrógeno amoniacal total (NAT) de la especie cultivada. Carassius auratus es un ornamental muy cultivado, debido a su tolerancia a diferentes condiciones ambientales. En este estudio se determinó el efecto del nivel de proteína cruda en la dieta sobre el crecimiento y excreción de NAT de C. auratus. Se evaluaron tres niveles de proteína cruda (30%, 40% y 45%) por un periodo de tres meses en acuarios de 40L a una densidad de 10peces/acuario. La temperatura del agua se mantuvo en 24±1°C y pH: 6.5-7. Los peces se alimentaron tres veces al día al 5% de la biomasa total. Semanalmente se llevó un control de parámetros fisicoquímicos: NAT, NO 2 -, NO 3 -, GH, KH, pH, temperatura y oxígeno disuelto. Mensualmente se registró la tasa de excreción de NAT y el crecimiento (peso, longitud total y estándar). Al final del experimento se estimaron los parámetros productivos de la especie. Los resultados indican que los parámetros productivos fueron similares en los tres tratamientos a excepción de GP, TCA y CR (p<0.05). El NAT excretado en C. auratus fue: 0.00075-0.0043 mgNAT/g de pez/día (30%PC); 0.001-0.037 mgNAT/g de pez/día (40%PC); 0.007-0.038 mgNAT/g de pez/día (45%PC). La información obtenida es de gran utilidad para el diseño de SCR y SA, pues permite establecer el tamaño del biofiltro, realizar cálculos de balance de masas y estimar el NO 3 -, importante nutriente en el crecimiento de plantas.Palabras clave: Sistemas de recirculación, sistemas acuapónicos, parámetros productivos y parámetros fisicoquímicos, goldfish.
