“…Three isonitrogenous (47% crude protein) semipurified diets were formulated to contain two levels of lipid and termed as 10% lipid diet, 15% lipid diet, and 15% lipid with 1% taurine supplement (namely, diets 10L, 15L, and 15L + T, respectively) (Table 1). The experimental diets were produced according to the method described in detail previously (Bai et al, 2021a). Finally, the pellets were stored in a refrigerator at −20 • C.…”

An 8-week feeding trial was conducted to investigate how dietary taurine supplementation attenuates the lipid deposition induced by dietary high lipid in juvenile orange-spotted grouper (Epinephelus coioides). Three isonitrogenous (47% crude protein) semipurified diets were formulated to contain two levels of lipid and termed as 10% lipid diet, 15% lipid diet, and 15% lipid with 1% taurine (namely, diet 10L, diet 15L, and diet 15L + T, respectively). Groupers fed diet 15L + T showed higher weight gain and feed efficiency compared with diet 15L. Groupers fed diet 15L showed higher liver lipid contents, plasma total cholesterol (TC), and leptin contents vs. those fed diet 10L. Diet 15L + T decreased hepatosomatic index, liver lipid content, and plasma TC and adiponectin contents, and increased liver 3-hydroxy-3-methy1 glutary1 coenzyme A reductase content compared with diet 15L. Fish fed diet 15L had higher contents of chenodeoxycholic acid, deoxycholic acid, and lithocholic acid, and lower contents of glycodeoxycholic acid (GDCA), glycolithocholic acid, glycoursodeoxycholic acid, taurodeoxycholic acid (TDCA), and β-, γ-, and ω-muricholic acid (MCA) when compared with fish fed diet 10L. Diet 15L + T downregulated the contents of glycocholic acid, glycochenodeoxycholic acid, taurohyodeoxycholic acid, tauromuricholic acid, TDCA, ursodeoxycholic acid, GDCA, and β-MCA vs. diet 15L. Diet 15L upregulated expression of peroxisome proliferator-activated receptor α (pparα) gene but downregulated expression of acyl-CoA carboxylase (acc), fatty acid synthase (fas), and glucose-6-phosphate dehydrogenase (g6pd) genes in comparison with diet 10L. The gene expression level of fas and 6pgd was downregulated and the pparα gene expression level was upregulated in fish fed diet 15L + T compared with those in fish fed diet 15L. Overall, this study indicated that dietary taurine supplementation can attenuate the liver lipid deposition of groupers caused by feeding 15% lipid through accelerating lipid absorption of taurine-conjugated bile acids and fatty acid β-oxidation and inhibiting lipogenesis.

“…The ingredients and proximate compositions of the experimental diets are presented in Supplementary Table S1. The experimental diets were manufactured and then stored at −20 °C prior to use as previously described (Bai et al, 2021). Juvenile groupers were obtained from a local hatchery (Zhangpu County, Fujian, China).…”

“…After 3 weeks of acclimation, a total of 360 fish with an initial wet weight of 10.5 ± 0.1 g were randomly distributed into four groups with triplicate 300 L tanks at a stock density of 30 fish per tank, within a recirculating system maintaining a water flow rate of 8 L/min. The feeding and management of fish were described as mentioned previously (Bai et al, 2021). During the feeding period, the water temperature was maintained at 28.0 ± 0.3 °C, the dissolved oxygen content was maintained at 6.2 ± 0.22 mg/L, and the ammonia nitrogen content was maintained at 0.19 ± 0.03 mg/L.…”

“…The proximate composition of ingredients, diets, and tissues was determined according to standard methods (Bai et al, 2021). Total lipids from liver and muscle samples were extracted with chloroform-methanol (2:1, vol/vol) solution according to the Folch protocol (Folch et al, 1957) and determined gravimetrically after drying a 5 ml aliquot under nitrogen.…”

“…The orange-spotted grouper (Epinephelus coioides) is a carnivorous fish species that is becoming an increasingly important farmed fish in the aquaculture industry in Southeast Asian countries, including China (Shapawi et al, 2019;Feng et al, 2020). Previous studies showed that dietary taurine addition can attenuate tissue lipid deposit of groupers (Koven et al, 2016;Lin and Lu, 2020); however, the underlying mechanism involved in the regulation of the lipid metabolism is not fully elucidated (Shen et al, 2019;Bai et al, 2021). As for associations of dietary lipids with the growth of the grouper, when the dietary lipid content was 10%, the fish species obtained ideal growth, but when dietary lipid content continued to increase (from 12 to 14%), the growth rate of the grouper showed a downward trend, accompanied by a marked increase in liver lipid accumulation (Luo et al, 2005).…”

A lipidomic analysis was conducted to provide the first detailed overview of lipid molecule profiles in response to dietary lipid and taurine and associations of liver lipid-lowering effects of dietary taurine with lipid molecular species and the positional distributions of fatty acids in the liver of juvenile orange-spotted groupers (Epinephelus coioides). The results indicated that the liver was more sensitive to varied dietary lipid and taurine contents than the muscle with regard to lipid molecules. A total of 131 differential lipid molecules (DLMs) were observed in the liver of groupers when dietary taurine was increased from 0 to 1% at 15% lipid, among which all the up and down-regulated DLMs are phospholipids (PLs) and triglycerides (TGs), respectively. The liver content of TGs containing 18:2n-6 attached at the sn-2 and sn-3 positions on the glycerol backbone increased with increasing dietary lipid from 10 to 15% but decreased with increasing dietary taurine from 0 to 1%. Therefore, dietary taurine can not only reduce lipid accumulation through decreasing the contents of TGs containing 18:2n-6 at the sn-2 and sn-3 positions but also enhance the anti-inflammatory capacity and health status of groupers. This study will also provide a new insight into the function of taurine in farmed fish.
