“…The relative increases in the saturated and polyunsaturated lipid fractions were only marginal. A significant increase in whole-body polyunsaturated lipid concentration was reported by Wang et al (2014). Nevertheless, these results were inconsistent with those reported in the present study.…”

Gross protein and fat requirements in formulated feeds designed for the honey gourami, Trichogaster chuna (initial weight 1.34–1.38 g), were investigated. Feeds containing 30%, 40%, and 50% protein and 6% and 9% lipid at each protein level were tested. Protein and energy sources used were from fishmeal, shrimp meal, clam meal, soy flour, and wheat flour. An equal mixture of crude sardine oil and groundnut oil was used as the source of lipids. Comparison of the whole gourami amino acid profiles before and after the dietary treatments indicated a relative decline in all amino acids except methionine and lysine. Fatty acid profiles of whole individuals after dietary treatment showed a substantial increase in monounsaturated fatty acids relative to the initial fatty acid profiles. No significant differences were observed in fish growth between dietary treatments (p > .05). Feeds containing 30% protein and 6% lipid were found to be adequate for normal growth, while feeds with 40% protein and 6% lipid were seen to help accelerate growth and reproduction. In this study, protein and lipid levels required for regular maintenance, sexual maturation, and spawning of aquarium‐reared gourami were established.

“…(). The optimal diets for gibel carp included 32% CP, 11.6% CL and less than 16% ash (Wang, Yang, et al., ). The CP content of bioflocs in this study was slightly lower for gibel carp culture, but CL content was much lower than optimal level.…”

This study evaluated the growth and immune response of gibel carp (Carassius auratus gibelio) cultured under no feed addition biofloc technology (BFT) system at different total suspended solid (TSS) concentrations (10, 300, 600, 800 and 1,000 mg/L for group BF0‐NF, BF300‐NF, BF600‐NF, BF800‐NF and BF1000‐NF) for 30 days. The results demonstrated that bioflocs contained rich nutrients, and gibel carp eaten bioflocs showed higher weight gain, specific growth and survival. Digestive enzyme activities such as pepsin and amylase increased significantly in BF300/600/800/1000‐NF groups than those in BF0‐NF group. Antioxidant response including superoxide dismutase and total antioxidant capacity in serum and skin mucus was also enhanced significantly (p < .05). In addition, six immune‐related genes were examined by RT‐qPCR. Compared with BF0‐NF group, expression levels of immune genes intelectin (ITLN), dual specificity phosphatase 1 (DUSP 1), keratin 8 (KRT 8), myeloid‐specific‐peroxidase (MPO), c‐type lysozyme (c‐lys) and interleukin‐11 (IL‐11) were up‐regulated by 78.1‐, 23.9‐, 13.8‐, 138.8‐, 401.8‐ and 91.1‐fold, respectively. The highest expression values were observed at TSS of 600–800 mg/L. This study suggested that bioflocs can be uptaken by gibel carp as a food source, and have a potential to be used as a supplemental food for aquaculture.

The growth performance, fatty acid composition, hepatic lipid content, hepatic somatic index and lipid peroxidation in Russian sturgeon were investigated using diets containing three lipid levels 50 g kg À1 (L5), 150 g kg À1 (L15) and 250 g kg À1 (L25) and three n-3/n-6 fatty acid ratios (1 : 3, 1 : 1 and 3 : 1) for 8 weeks. Weight gain significantly increased with the increase in dietary lipid levels at n-3/n-6 fatty acid ratios of 1 : 3 and 1 : 1, but not at the 3 : 1 ratio. Correspondingly, fish survival gradually decreased with the increase in dietary lipid at the 3 : 1 n-3/n-6 fatty acid ratio. The dietary lipid level significantly affected the composition of whole-body fatty acid. The retention of highly unsaturated fatty acid dramatically decreased at the level of 250 g kg À1 dietary lipid. The liver malondialdehyde increased with the increase in dietary lipid levels and the n-3/n-6 fatty acid ratios. The contents of lipid and triglyceride in the liver and the hepatic somatic index also increased with the increase in dietary lipid. The diet combination of L25 + 3 : 1 showed the highest aspartate transaminase and alanine transaminase, indicatives of hepatic injury. This study indicates that the L25 + 1 : 3 diet can improve fish growth performance, whereas the L25 + 3 : 1 diet may lead to poor growth performance due to high lipid peroxidation.
