“…For instance, Dias et al [14] found that high soybean meal diet can reduce the FAS activity of European perch liver; Tian Juan et al [15] reported that adding the appropriate level of carnitine significantly reduced the FAS activity of the liver of fish. Meanwhile related research also shows that the higher the dietary lipid level is, the lower the FAS activity is [16]. In this experiment, the FAS activities of the hepatopancreas and kidney of common carp was in negative correlation to dietary lipid levels, and the FAS activities of the hepatopancreas decreased significantly (P<0.05), indicating the dietary lipid levels failed to produce the induction to the secretion of FAS activity.…”

“…This indicates that lipid accumulation in fish is tissue-biased, and lipids seem to be mainly deposited in the viscera. Similar studies on fish have indicated that a high-lipid diet increases the abdominal fat index and hepatopancreas fat content, as observed in Russian sturgeon (Acipenser gueldenstaedtii) [37], grass carp [24,25], and rockfish (Sebastes schlegelii) [38]. It is well-known that greater fat deposition occurring in the viscera (led by high-energy diets) can reduce the commercial value of the product [39].…”

In the present study, our aim was to assess the effect of dietary black soldier fly oil (BSFO) with different lipid contents on the growth performance, body composition, lipid metabolism, and related gene expression in juvenile mirror carp (Cyprinus carpio var. specularis). An 8-week feeding trial was conducted using four isonitrogenous diets (32.0% crude protein) containing two lipid levels: 6% (control (CT) group) and 9% (high lipid (HL) group), both using soybean oil as the oil source. The other two diets contained BSFO on the basis of 6% and 9% lipid, referred to as (CT + BSFO) and (HL + BSFO) groups. The results showed that final body weight, weight gain rate, specific growth rate, protein retention ratio, and feed utilization were significantly increased by using higher dietary lipid levels (P<0.05). Additionally, the gene expression of lipid synthesis markers was significantly up-regulated in intra-peritoneal fat but significantly down-regulated in the hepatopancreas due to increased dietary lipid level (P<0.05). No negative effects on feed utilization or growth performance were observed in fish fed diets containing BSFO. However, the intra-peritoneal fat index, adipocyte size, and hepatopancreas lipid content were significantly decreased in the CT + BSFO group compared to the CT group (P<0.05). Furthermore, BSFO also up-regulated the expression of lipid lipolysis markers in the hepatopancreas and intra-peritoneal fat (P<0.05). Moreover, the use of BSFO also increased the content of n-3 polyunsaturated fatty acid (PUFA) while reducing the content of n-6 PUFA in the muscle (P<0.05). In conclusion, HL diets improved the growth of the fish and increased the lipid deposition. BSFO in the diet resulted in a reduction of lipid deposition in the hepatopancreas and intra-peritoneal fat, likely due to an increase in lipid oxidation.

“…Lipase activity can be recognized as an indicator of lipid utilization for animals. Previous studies showed dietary bile acids supplementation improved lipase activity as described in European eels (Zhai et al, 2020), rainbow trout (Adhami et al, 2017), large yellow croker (Ding et al, 2020), tilapia (Jiang et al, 2018), tongue sole (Li et al, 2021b), prenant's schizothoracin (Zeng et al, 2016;Xiang et al, 2019). Generally, bile acids are composed of a convex hydrophobic face and a concave hydrophilic face, this amphipathic structure is facilitated to lipid emulsification and breaks down large lipid molecules into small globules (Jiang et al, 2018), which provides lipase a higher surface area to digest lipids by catalyzing the hydrolysis of ester bonds (Romano et al, 2020).…”

Now the replacement of fish oil (FO) with vegetable oils (VOs) has been broadly applied in aquatic feed, but studies reported that there were negative effects on growth, skin color, flavor and muscle texture. A 10-week feeding trial was conducted to investigate the effects of dietary mixed bile acids (BA) on growth performance, body composition, digestive enzyme activities, skin color and flesh quality of juvenile large yellow croaker (initial weight, 13.10 ± 0.18 g). Four iso-nitrogenous and iso-lipidic experimental diets were formulated and designated as soybean oil (SO), SO supplemented with 300 (BA300), 600 (BA600), and 1200 (BA1200) mg/kg bile acids. Two hundred and forty fish were randomly allocated into 12 floating net cages (1 m × 1 m × 1.5 m) that were located at marine fishing rafts. Each diet was randomly distributed in triplicate (three replicates per treatment, 20 fish per replicate). Fish were hand-fed to apparent satiation twice daily (05:30 and 17:30) for 10 weeks. Results showed that specific growth rate presented quadratic pattern with supplemental bile acids level, peaking at BA600 group. Meanwhile, feed conversion rate of cultured fish was significantly improved in BA600 group (P < 0.05). The redness (a*) of dorsal and lateral line skin and the yellowness (b*) of abdominal skin showed significantly quadratic pattern with the increase of supplemental BA level (P < 0.05), peaking at BA600 group. In terms of dorsal muscle texture, springiness showed a decreasing trend in significantly linear pattern with the increase of supplemental BA level, bottoming at BA600 group. However, cohesiveness and gumminess were significantly linear increased with the increase of supplemental BA level (P < 0.05). No significant differences were observed in lipase, amylase, and trypsin activities (P > 0.05). Total proportion of muscle n-3LCPUFA showed a linearly increasing trend with the increase of supplemental BA level. Muscle TG content was linearly increased with the increase of supplemental BA level (P < 0.05), and significant differences occurred as compared to fish fed diets with SO when supplemental BA level were reached 600 mg/kg and 1200 mg/kg (P < 0.05). The gene expression of acyl-CoA oxidase (aco) was significantly decreased in fish fed diets supplemented with 600 mg/kg bile acids compared with 300 mg/kg other than those fed diets with SO. In conclusion, these results suggested that mixed bile acids supplemented to SO-based diets could improve feed conversion ratio, skin color and flesh quality to some extent.
