“…Fish fed diets containing high lipid contents tended to have higher FCR than fish fed low lipid diets in the present study. FCR in this study ranged from 2.63–3.48; these values are higher than that found in river chub fed fish meal‐based diets (FCR = 2.44) at the same dietary protein level (Shyong, Huang & Chen 1998). It is possible that fish meal contains some unknown growth factor for river chub that is not available in casein.…”

“…Five isocaloric and isonitrogenous purified diets were prepared to contain 3.2 kcal g −1 metabolizable energy and 30% crude protein (Shyong et al 1998). Estimated metabolizable energy was calculated using values of 4.5, 8.51, and 3.49 kcal g −1 for protein (Smith 1971), lipids (Chiou & Ogino 1975), and carbohydrates (Austreng 1978) respectively.…”

“…It is well known that the protein content of diets should be at a level that minimizes feed costs, but supports rapid growth and efficient protein utilization. In a previous study, using white fish meal as the protein source, we demonstrated that the dietary protein requirement of river chub was between 30 and 35% (Shyong, Huang & Chen 1998). Many studies have shown that providing adequate energy with dietary lipids can minimize the use of protein as an energy source (Lee & Putnam 1973; Watanabe, Takeuchi & Ogino 1979; Johnsen & Wandsvik 1990).…”

A feeding trial was conducted to investigate the effects of dietary lipid level on growth and body composition of juvenile river chub, Zacco barbata (Regan). Juvenile river chub with 0.26 g body weight were given five isoenergetic and isonitrogenous purified diets containing 0–20% lipids in 5% increments for 8 weeks. The dietary lipid source was a 1:1 (w/w) mixture of menhaden fish oil and soybean oil. There was no significant difference on weight gain, feed conversion ratio, or protein efficiency ratio, among fish fed different experimental diets (P > 0.05). Body fat contents of both initial fish and fish fed the diet containing 20% dietary lipid were significantly greater than those fed other diets (P < 0.05). The percentage of total n‐3 fatty acids in the body lipids of fish at the beginning of the trial was 12.34%. This value decreased to 3.83% by the end of the trial for fish fed a control diet with no supplemented lipid. Similar trends were observed in linoleic acid contents that were 6.11% and 3.09%, respectively, for initial fish and the fish fed the control diet for 8 weeks. However, the absolute amount of these fatty acids stayed the same in the initial and in the control group. Meanwhile, as dietary lipid level increased, the percentages of these fatty acids in body lipids of fish at the end of the trial also increased.

“…The differences could be attributed to the type of diet, because wild fish are apt to capture algae, insect larvae and crustacean (Steffens 1997). As far as cultured fish are concerned, the composition of the diets has been identified as the main reason for the observed differences in body composition (Shyong et al. 1998; Lanari et al.…”

The biochemical composition of dorsal muscle from large yellow croaker (Pseudosciaena crocea) cultured in China was studied. The comparison was made between the fish fed raw fish (RF) and commercial feed (CF). Two‐year‐old fish cultured in floating net cages were sampled for analysis. Moisture, protein, lipid and ash contents were determined. Amino acid composition was determined by an automatic amino acid analyzer. Fatty acid profile was determined by gas chromatography. The analysis results showed that fish in the CF group had lower levels of crude fat content and essential amino acids content (P < 0.05). The percentages of total saturated fatty acids and monounsaturated fatty acids were significantly higher, while the corresponding total polyunsaturated fatty acids content was significantly lower in the CF group. In the two groups, eicosapentaenoic acid, docosahexaenoic acid content and the ratio of n‐3 to n‐6 fatty acids were found to be generally high. PRACTICAL APPLICATIONS Large yellow croaker (Pseudosciaena crocea) is popularly cultured in China. It is mainly reared with raw fish and commercial feed. This study examined the biochemical composition of fillets from large yellow croaker. It was found that the fish species possess high nutritive value, which is very beneficial for human nutrition and health. This article also explored the effects of diets on flesh quality, which can be useful in the seafood production and feed industry.

O estudo foi desenvolvido no Laboratório de Piscicultura do Departamento de Zootecnia da Universidade Federal de Santa Maria, com duração de oito semanas, de abril a junho de 2011. O objetivo foi definir o melhor nível de incorporação do resíduo de peixes na alimentação de juvenis de jundiá, em sistema de recirculação d'água, utilizando-se 450 alevinos de jundiás, com peso médio inicial de 7,2±0,27g. Foram testadas cinco diferentes dietas, em três repetições, com níveis diferentes (0; 3,75; 7,5; 15; e 30%) de incorporação de farinha de carcaça de jundiás com vísceras (FCJCV). As dietas continham, aproximadamente, 37% de PB e 3200kcal de EM/kg de dieta. Foram coletados dados de ganho em peso diário, sobrevivência, fator de condição, taxa de crescimento específico, conversão alimentar aparente, rendimento de carcaça, taxa de eficiência proteica e deposição de proteína e lipídio corporal. O maior ganho de peso foi para o nível 30% de inclusão de FCJCV, com peso final de 45,47g e ganho em peso diário de 0,68g/dia. A dieta com nível de 30% de inclusão de FCJCV apresentou melhores valores para taxa de crescimento específico (3,34%/dia), conversão alimentar aparente (1,05: 1), biomassa final 1.105,45g, deposição proteica corporal (64,9mg/dia), taxa de eficiência proteica (1,9) e coeficiente de retenção proteica (1,96%). Concluiu-se que a utilização de farinha de resíduos de processamento de jundiá no nível de 30% de inclusão na dieta foi a que apresentou maior eficiência no desenvolvimento de juvenis de jundiá.
