“…Blue streak hap also appeared to have higher protein requirements than other ornamental omnivorous fishes such as goldfish (29%) (Carassius auratus) (Lochmann and Phillips, 1994), dwarf gourami (25%) (Colisa lalia) (Shim et al, 1989) but lower than carnivorous fishes such as swordtails (45%) (Xiphorus helleri) (Kruger et al, 2001), discus (45%) (Symphysodon spp.) (Chong et al, 2000).…”

An experiment was designed to determine the optimum dietary protein level of a freshwater ornamental fish, Blue streak hap (Labidochromis caeruleus). Four isocaloric fish meal based diets ranging from 30% to 45% in protein were fed to triplicate groups of Blue streak hap for 8 weeks. Fish (initial weight, 0.85 g) were reared in twelve 50 L aquarium with biological filter and controlled temperature (27.5°C), in stocking density of ten fish/aquarium. Results showed that dietary protein level significantly influenced final weight, weight gain and specific growth rate of fish. Maximum growth of fish was observed in the 40% protein diet, although this was not significantly different from the 35% and 45% protein diets (P>0.05). Specific growth rate and feed efficiency increased from 30% to 40% protein, and thereafter decreased for diet 45% protein.There were statistically significantly differences in feed intake among treatments (P<0.05). Fish fed with the highest protein diet had lower percentage daily feed consumption values than those of fish fed with the lowest protein diet. Under the experimental conditions applied, juvenile blue streak hap, L. Caeruleus, appear to require more than 35% dietary protein for optimized growth.

“…Although the importance of goldfish on ornamental fish market scenario, until now, just two studies have reported the protein and amino acid requirement for this species (LOCHMANN;PHILLIPS, 1994;FIOGBÉ;KESTEMONT, 1995). However, none have studied the influence of digestible energy level on protein requirement.…”

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...

“…Menurut Hertrampf & Piedad-Pascual (2000), kecernaan protein (true digestibility) kasein untuk ikan mas (Cyprinus carpio) sebesar 99%. Oleh karena itu, kasein juga telah digunakan sebagai bahan pakan ikan hias di antaranya pada ikan guppy (Shim & Chua, 1986), ikan mas koki (Lochmann & Phillips, 1994), ikan tin foil barb (Elangovan & Shim, 1997), dan ikan discus (Chong et al, 2000).…”

ABSTRAKBudidaya ikan rainbow kurumoi (Melanotaenia parva) umumnya menggunakan pakan alami, namun ketersediaan tidak stabil sehingga perlu pakan buatan untuk suplementasi atau menggantikannya. Tujuan penelitian ini adalah untuk mengetahui tingkat penggunaan kasein yang paling efisien dalam formulasi pakan benih ikan rainbow kurumoi. Ikan rainbow kurumoi berumur satu bulan ditebar dengan kepadatan 30 ekor/wadah dalam 12 akuarium berukuran 60 cm x 40 cm x 40 cm. Perlakuan yang diujikan adalah tingkat penggunaan kasein dalam pakan sebanyak 0%, 5%, 10%, dan 15%. Parameter yang diamati meliputi: efisiensi pakan, konversi pakan, panjang mutlak, bobot mutlak, laju pertumbuhan spesifik, dan sintasan. Pengukuran kualitas air, profil asam amino dan asam lemak pakan dilakukan sebagai data penunjang. Hasil penelitian dapat disimpulkan bahwa penggunaan kasein 10% dalam pakan benih ikan rainbow kurumoi paling efisien yaitu 80,67%.
