“…In accordance, black seabream, A. schlegelii, fed a combination of BS and L-carnitine recorded the highest growth performance and feed utilization compared with individual supplementations [30]. BS supplementation could improve growth performance by enhancing nutrient absorption pathways via regulating ionic transport in the intestine of Senegalese sole, Solea senegalensis [28]. Additionally, LTN has antioxidant activity and can modulate the antioxidant balance in fish [69,70], which was confirmed in the current findings (Figure 1).…”

“…Accordingly, the determination of carotenoid content in the present study showed the highest accumulation in the BS+LTN supplemented group (Table 4). Moreover, BS could maximize the role of lipids as a protein sparing effect, especially in fish, which use lipids as the main source of metabolic energy [28,67]. Additionally, this could be interpreted as the significant increase in the whole-body ether extract of fish fed BS alone or in combination with LTN in the current findings.…”

“…They have an emulsification effect on lipids to facilitate the enzymatic digestion and absorption of fat and fat-soluble nutrients (vitamins, carotenoids, and phospholipids) [26]. Furthermore, BS also have several metabolic functions, such as the activation of bile salt-activated lipase in fish [27], improving nutrient absorption [28], increasing the solubility of amino acids (glycine and taurine) [29], and maintaining cholesterol homeostasis in the liver [26,29], among others.…”

A 60-day feeding trial was conducted to assess the effects of dietary supplementation with bile salts (BS), lutein (LTN), and their combination on growth, survival, carotenoid content, and antioxidant status of rabbitfish (Siganus rivulatus) larvae. Fish were fed four isonitrogenous (34.39% protein) and isoenergetic (20.57 kJ/g) diets supplemented with BS (0.15 g kg−1), LTN (0.1 g kg−1), BS+LTN (0.15 and 0.1 g kg−1, respectively), and a non-supplemented control diet. The results revealed that fish fed BS+LTN had the highest significant specific growth rate (4.37% day−1), feed efficiency (46.55%), and survival (97.78%). Lutein supplementation improved whole-body protein content, meanwhile, fish fed a BS-supplemented diet had a higher lipid content. The carotenoid deposition was significantly increased with LTN and BS+LTN in skin, muscle, and whole body compared to the control and BS treatment. All dietary supplementation of BS and LTN showed significant improvement in total antioxidant capacity, catalase, and glutathione peroxidase activities. Additionally, LTN alone or BS+LTN significantly reduced malondialdehyde levels by 5.30 and 29.91%, respectively compared to the control. BS supplementation modulated aminopeptidases activities, triglycerides, cholesterol, and increased the activity of pancreatic lipase. Therefore, it could be inferred that dietary supplementation with LTN in combination with BS could improve the growth performance, carotenoid deposition, antioxidant status, lipid digestion, and metabolism of S. rivulatus.

“…The main functions of bile acids are to be an emulsifier to promote fat digestion and absorption for animals (Hofmann & Hagey, 2008). Dietary BA supplementation has been shown to improve lipid utilization in tilapia (Jiang et al, 2017), grass carp (Zhou et al, 2017), largemouth bass (Yin et al, 2021) and large yellow croaker (Ding et al, 2020), regulate ion transport in the intestine in Senegalese sole (Fuentes et al, 2018) and regulate liver lipid homeostasis in tiger puffer (Liao et al, 2020). However, fewer studies focused on BA in the shrimp diet rather than fish.…”

The study evaluated the effects of bile acids (BA) supplementation in soybean meal (SBM)‐based diet on growth, cholesterol concentrations, nutrient digestibility and moulting‐related gene expression in white shrimp, Litopenaeus vannamei. Control diet with 485.1 g kg‐1 SBM was supplemented with 0, 1 and 2 g kg−1 of BA. Together with a reference diet with fish meal, total of four diets were fed to triplicate groups of shrimp (initial weight: 2.20 g) in a recirculation system for 56 days. Weight gain was higher (p < 0.05) in shrimp fed the reference diet than in shrimp fed the control diet. Shrimp fed the reference diet had higher whole body, hepatopancreatic and haemolymph cholesterol concentrations, dry matter, lipid and cholesterol digestibility than other treatments. The expression of the ecdysteroid receptor gene was the highest in shrimp fed the reference diet and the diet with 0.2% BA, followed by shrimp fed the diet with 1 g kg−1 BA and the lowest in shrimp fed the control diet. Shrimp fed the reference diet, and diets with 1 and 2 g kg−1 BA exhibited higher retinoic‐X receptor, chitinase and chitin synthease gene expression than shrimp fed the control diet. Haemocyanin gene expression was higher in shrimp fed the reference diet than in shrimp fed the control diet. The results indicated that shrimp fed high SBM diet showed low body cholesterol concentrations, digestibility and moulting‐related gene expression for white shrimp. Bile acids supplementation in SBM‐based diet can improve moulting‐related gene expressions but not for another physiological parameter.

“…Regulated by different transport proteins, these salts are released into the intestinal lumen through enterohepatic circulation ( Trauner & Boyer, 2003 ). Because bile salts can help intestines to digest and absorb dietary lipids and fat-soluble vitamins ( Haslewood, 1967 ; Fuentes, Ribeiro & Arago, 2018 ), they are included in the diet of fishes to improve growth and digestive enzyme activities ( Deshimaru, Kuroki & Yone, 1982 ; Alam et al, 2015 ). Moreover, many studies on behaviour and physiology have reported that bile salts are important chemical signalling substances as well as effective olfactory stimuli in fishes, which have distinct sensitivity to different components ( Zhang, Brown & Hara, 2001 ; Døving, Selset & Thommesen, 1980 ), but molecular studies have been limited.…”

Fish produce and release bile salts as chemical signalling substances that act as sensitive olfactory stimuli. To investigate how bile salts affect olfactory signal transduction in large yellow croaker (Larimichthy crocea), deep sequencing of olfactory epithelium was conducted to analyse olfactory-related genes in olfactory transduction. Sodium cholates (SAS) have typical bile salt chemical structures, hence we used four different concentrations of SAS to stimulate L. crocea, and the fish displayed a significant behavioural preference for 0.30% SAS. We then sequenced olfactory epithelium tissues, and identified 9938 unigenes that were significantly differentially expressed between SAS-stimulated and control groups, including 9055 up-regulated and 883 down-regulated unigenes. Subsequent Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses found eight categories linked to the olfactory transduction pathway that was highly enriched with some differentially expressed genes (DEGs), including the olfactory receptor (OR), Adenylate cyclase type 3 (ADCY3) and Calmodulin (CALM). Genes in these categories were analysed by RT-qPCR, which revealed aspects of the pathway transformation between odor detection, and recovery and adaptation. The results provide new insight into the effects of bile salt stimulation in olfactory molecular mechanisms in fishes, and expands our knowledge of olfactory transduction, and signal generation and decline.
