“…Different species of fish have shown wide variations in their patterns of protein needed for good zootechnical performance. Lateolabrax japonicus exhibited weight gain increases with up to 41 % protein in the diet (Ai et al, 2004), Ictalurus punctatus achieved maximum growth with 35% dietary protein (Li et al, 1998) and Oreochromis niloticus and O. mossambicus had the best net protein utilization and feed conversion results with crude protein levels of 30 %. According to Eckmann (1987), C. macropomum's best performance was achieved with 36 % protein, corroborating the results of the present study, in which specimens showed significant growth and weight gain results with 36-37 % protein in the diet over a period of 30 days.…”

The physiological responses of juvenile tambaqui (Colossoma macropomum) fed commercial feed supplemented with different concentrations of camu camu (Myrciaria dubia) were evaluated. The design was completely randomized, with treatments arranged in a factorial design with three proportions of camu camu (15%, 30% and 45%) and a control treatment (100% commercial diet), with four replicates per treatment. A total of 96 tambaqui specimens were used, with a mean initial weight of 11.69 ± 2.68 g and a mean length of 7.06 ± 0.44 cm. After 30 days, hematological parameters, metabolic variables, growth and fish swimming performance were evaluated. The different proportions of camu camu in the diet did not cause significant changes to the tambaqui's hematological parameters during the feeding period, except for hemoglobin (Hb) concentration and mean corpuscular hemoglobin concentration (MCHC) after the 30th day, and hematocrit (Ht) after the swimming stress test, which increased significantly (p < 0.05). The significant increases in metabolic variables, such as cortisol, glucose, proteins and triglycerides, and in hematologic variables after the Ucrit test reflect, respectively, biochemical adaptations for maintenance of the energy mobilization process and a regulatory necessity in tissue oxygen demand during intense exercise. Fish fed 15% and 30% camu camu gained the most weight and achieved the best swimming performance, respectively. The results for camu camu concentrations above 30% suggest a saturation of its intrinsic properties in the diet at this level and a loss of nutrients from the commercial feed replaced by the fruit, reducing productive performance and nutritional assimilation.Keywords: Amazon, Colossoma macropomum, Myrciaria dubia, hematology, ascorbic acid. Alterações em parâmetros fisiológicos de tambaqui (Colossoma macropomum) alimentados com dietas suplementadas com fruta amazônica camu camu (Myrciaria dubia) ResumoAs respostas fisiológicas de juvenis de tambaqui (Colossoma macropomum) alimentados com ração comercial suplementada com diferentes concentrações de camu camu (Myrciaria dubia) foram avaliados. As amostras analisadas foram inteiramente casualizadas, com os tratamentos arranjados em esquema fatorial com três proporções de camu camu (15%, 30% e 45%) e um tratamento controle (ração comercial 100%), com quatro repetições por tratamento. Um total de 96 amostras de tambaqui foram utilizadas, com um peso médio inicial de 11,69 ± 2,68 g e um comprimento médio de 7,06 ± 0,44 cm. Após 30 dias, foram avaliados os parâmetros hematológicos, variáveis metabólicas, crescimento e desempenho natatório de peixes. As diferentes proporções de camu camu na dieta não causou alterações significativas nos parâmetros hematológicos dos tambaquis durante o período de alimentação, com exceção de hemoglobina (Hb) e concentração de hemoglobina corpuscular média (CHCM), após o 30º dia, e hematócrito (Ht), após o teste de nataçãoBraz.

“…Therefore, it is imperative to study Japanese seabass nutritional requirements to develop cost-effective and nutritionally balanced feed formation for its culture. To date, although some information has been published concerning the nutrient requirements for Japanese seabass reared in freshwater or seawater (Gao et al 1998;Pan et al 2000;Ai et al 2004;Mai et al 2006;Ai et al 2007), the basic studies concerning its nutritional requirements are still lacking.…”

Triplicate groups of 40 Japanese seabass Lateolabrax japonicus (initial weight, 11.3 ± 0.4 g) reared in seawater (salinity, 30.0-33.0 g L -1 ) were fed with five isonitrogenous (41.3 ± 0.2% crude protein) and isoenergetic (18.5 ± 0.3 MJ kg -1 ) experimental diets formulated with increasing lipid levels (4.3, 8.4, 12.2, 15.8 and 20.1% lipid) for 10 weeks. Survival throughout the feeding experiment ranged from 87.5 to 100%, but the survival of fingerlings fed with the 4.3% lipid diet was significantly lower than the rest of the diets. At the end of the feeding experiment, fish fed with 12.2% lipid diet showed optimal growth performance (P \ 0.05). Lipid contents of whole body, liver and muscle increased in parallel with the increase in dietary lipid levels. Viscerosomatic index (VSI), hepatosomatic index (HSI) and muscle lipid content were higher in 20.1% lipid group than those in the rest of the lipid level groups indicating that viscera and muscle tissues played important contributions to body lipid deposition. High proportions of 18:1n-9, eicosapentaenoic acid (20:5n-3; EPA) and docosahexaenoic acid (22:6n-3; DHA), and low concentrations of n-6 polyunsaturated fatty acids (PUFAs) occurring in liver and muscle, to some extent, reflected fatty acid (FAs) composition in the experimental diets.

“…Similar results were obtained in gilthead seabream (Zohar et al, 1995), rainbow trout (Pereira et al, 1998), tilapia (Cumaranatunga and Thabrew, 1989), sharpsnout seabream (Hernandez et al, 2007), channel catfish (Sink et al, 2010) and gold fish (Bagheri et al, 2013 (Vergara et al, 1996;Gangadhar et al, 1997;Regost et al ., 2001). Ai et al (2004) also reported that carcass lipid content of juvenile Japanese seabass, Labrax japonicas, positively correlated with the dietary lipid level and ash content however, inversely correlated with moisture content. In contrast, Regost et al (2001) found no significant difference in whole body moisture and ash content of fish body in fishes fed with different diets.…”

Abstract:The aim of the present study was to evaluate the effect of plant and animal sources in the diet of Labeo rohita with an overall goal of gaining sustainable fish and egg production. Fishes with an initial weight of 310-323 g were fed with five different isocaloric (3Kcalg rohita. Hence, Our study revealed that for higher growth and better broodstock development, L. rohita may be fed on diet formulated with 30% rice bran, 50% groundnut meal and 20% fish meal.
