“…TG and CHOL are the main components of blood lipids. With the increasing of dietary n-3 LC-PUFA levels, the serum TG decreased significantly and the minimum was reached in the 1.70% group, which was consistent with silvery-black porgy (Sparidentex hasta) (Mozanzadeh et al, 2015) and golden pompano (Li et al, 2020). HDL-C partly inhibited the uptake and degradation of LDL-C, thereby inhibiting the change of sterol level induced by LDL-C (Carew et al, 1976).…”

“…However, the high proportion of VOs diet is likely to cause abnormal lipid deposits, decrease flesh quality and immunity in fish Montero et al, 2003;Trushenski et al, 2011). Many literature have shown that n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) such as eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3) are involved in the composition of fish cell membranes and play an critical role in growth, reproduction, lipid metabolism and immune response (An, Dong, Tan, Wu, et al, 2020;Li et al, 2020;Luo et al, 2019;Tocher, 2015;Zuo et al, 2012).…”

“…Adipose triglyceride lipase (atgl), carnitine palmitoyl transferase (cpt-1) and lipoprotein lipase (lpl) mainly regulate in fatty acid β-oxidation and lipolysis (Kerner & Hoppel, 2000;Ma et al, 2013). Many studies have reported that n-3 LC-PUFA can reduce lipid deposition by promoting β-oxidation capacity and affecting lipidmetabolism-related gene expression in golden pompano (Trachinotus ovatus) (Li et al, 2020) and black seabream (Acanthopagrus schlegelii) . Similarly, feeding grass carp (Ctenopharyngodon idellus) rich in n-3 LC-PUFA diet can significantly decrease the mRNA expressions of sterol regulatory element-binding protein (srebp-1), fas, accα, peroxisome proliferator-activated receptor γ (pparγ) and significantly increase proliferator-activated receptor α (pparα) (Li et al, 2015).…”

To determine the effects of dietary n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) on lipid metabolism and intestinal health of juvenile hybrid grouper (♀ Epinephelus fuscoguttatus × ♂ Epinephelus lanceolatu), an 8-week feeding experiment was carried out using six isoproteic and isolipidic formula diets containing 0.65% (control), 1.00%, 1.35%, 1.70%, 2.05% and 2.40% n-3 LC-PUFA (dry matter). The results showed that the serum triglyceride and cholesterol reached the minimum in the 1.70% group and 1.35% group, respectively. The serum glucose content of the control group was significantly lower than that of the other groups (p < 0.05). Compared with the control group, the expression of hepatic cpt-1 gene in the 2.05% group and atgl, apob-100 genes in the 2.40% group reached the maximum and increased significantly, while fas, accα and pparγ genes in the 2.05% and 2.40% groups decreased significantly (p < 0.05). The cpt-1, atgl and pparα gene expression in the muscle increased first and then decreased, reaching the maximum in the 1.70% and 1.35% groups, while the expression of fas and pparγ significantly decreased (p < 0.05), reaching the minimum in the 2.40% and 2.05% groups, respectively. Intestinal lipase and trypsin activities in the 2.05% group reached the maximum. In the intestine microbiota, Proteobacteria, Bacteroidetes and Firmicutes were the dominant phyla. The

“…Juvenile black seabream ( Acanthopagrus schlegelii ) fed n‐3 HUFA at a moderate level (1.34%–1.80% n‐3 HUFA) exhibited an increase growth and antioxidant capacity (Jin et al., 2017). A study of the antioxidant capacity of marine teleost golden pompano ( Trachinotus ovatus ) receiving dietary n‐3 HUFA showed that total antioxidant capacity, catalase and total superoxide dismutase were significantly increased when the fish were fed with diet containing 1.24%–1.73% n‐3 HUFA (Li et al, 2020). In seahorses, H. erectus fed Artemia nauplii enriched with 27 μl/L HUFAs had reduced lipid peroxidation products by enhancing antioxidant enzyme activities, such as glutathione peroxidase and superoxide dismutase (Yin & Tang, 2012).…”

Many seahorse species, including the longsnout seahorse, Hippocampus reidi are traded for medicinal and aquaria purposes (Rosa, Sampaio, & Barros, 2006). Based on the database from the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Trade, approximately 7 million individuals within 70 countries or regions comprise the sources and/ or consumers of the seahorse trade. Hong Kong consumed 57% of the total seahorse trade volume (Evanson, Foster, Wiswedel, &

“…The broken-line analysis indicated the optimal dietary lipid level should be 107 g/kg at two dietary fish meal levels (the regression equation was Y = 71.768 + 0.346X and Y = 99.514 + 0.086X at 280 g/kg fish meal level, and the regression equation was Y = 66.722 + 0.351X and Y = 108.925 − 0.045X at 140 g/kg fish meal level, where Y is weight gain and X is dietary lipid level). In previous studies, dietary lipid level for golden pompano was formulated at 65 g/kg (Ma et al, 2014;Wang et al, 2013Wang et al, , 2017Wu et al, 2015), 105 g/kg (Tan et al, 2016(Tan et al, , 2017 or 130 g/kg (Li et al, 2020;Lin et al, 2013Lin et al, , 2015Ma et al, 2020;Niu et al, 2013Niu et al, , 2016Wang et al, 2019;Xun et al, 2019;Zhou et al, 2015). Compared with the other fish species, the optimal dietary lipid level for golden pompano is similar to that (104-106 g/ kg crude lipid) for starry flounder Platichthys stellatus (Ding et al, 2010) and large yellow croaker Larimichthys croceus (Yi et al, 2014), but is higher than that (80-82 g/kg crude lipid) for Florida pompano…”

A feeding trial was conducted to determine the optimal dietary lipid level for golden pompano Trachinotus ovatus and the effect of dietary lipid level on fish meal replacement with soy protein concentrate (SPC). Eight isonitrogenous diets were formulated to contain four lipid levels (65 g/kg, 85 g/kg, 105 g/kg and 125 g/kg) and two fish meal levels (280 g/kg and 140 g/kg) respectively. Fish (initial weight 25.2 ± 0.5 g) were fed the test diets in net pens for 7 weeks. At the same dietary fish meal level, weight gain and nitrogen retention efficiency (NRE) tended to increase, while feed intake, feed conversion ratio (FCR) and nitrogen waste tended to decrease, with elevating dietary lipid level from 65 g/kg to 105 g/kg. At the same dietary lipid level, no significant differences were found in weight gain, feed intake, FCR, NRE, condition factor, hepatosomatic index, proximate composition and nitrogen waste between fish fed the diets containing 280 g/kg and 140 g/kg fish meal. This study reveals that the optimal dietary lipid level for golden pompano should be 107 g/kg, and dietary fish meal level could be reduced to 140 g/kg by using SPC as a fish meal substitute. Elevating dietary lipid level could not significantly increase fish meal replacement level with SPC.

Replacement of fish meal with alternative ingredients in aqua-feed has been regarded as a key for establishing sustainable aquaculture industry (Naylor et al., 2009). Among the plant ingredients used in aqua-feed, soybean has been demonstrated as an excellent protein source due to its high protein digestibility, relative balance of amino acids, huge global production and reasonable market price (Metts et al., 2011; How to cite this article: Ren X, Zhu M, Wu YB, et al.
