“…Previous observation in fish (Espe and Holen, 2013;Goto et al, 2001Goto et al, , 2003Takagi et al, 2005) and mammals (Bosgelmez et al, 2008;Nandhini et al, 2002;Pasantes-Morales et al, 1980;Sawosz et al, 2004) identified the liver as a primary importance for taurine metabolism. Although the absence of significant change in AST and ALT activities suggests an absence of liver damage by the end of the present experiment, this is likely due to the short duration of this experiment.…”

“…The sources of taurine in fish are de novo synthesis and dietary. However, many fish species have extremely low taurine biosynthesis abilities and they are much more dependent on dietary intake (Yokoyama, Takeuchi, Park & Nakazoe 2001;Goto, Matsumoto, Murakami, Takagi & Hasumi 2003;Kim, Matsunari, Takeuchi, Yokoyama, Furuita, Murata & Goto 2008). Fishmeal is known to be the major source of taurine in aquafeeds.…”

Taurine is one of the conditionally essential amino acids for fish. Its metabolism has attracted much attention in fish nutrition due to the substitution fishmeal with plant ingredients, which barely contain taurine. However, little is known about the mechanisms of taurine homoeostasis in turbot (Psetta maxima), an economically valuable carnivorous fish with limited taurine biosynthesis ability. In this study, we obtained the full-length cDNA of turbot taurine transporter (PmTauT) and classified its tissue distribution in juvenile turbot and substrate regulation in isolated turbot muscle cells. Full-length PmTauT cDNA was 2566 bp containing a 58 bp 5 0 untranslated region (UTR), a 633 bp 3 0 UTR and a 1875 bp open reading frame (ORF) encoding 624 amino acid residues. The deduced protein contained 12 putative transmembrane domains and showed highest similarity with taurine transporter from Senegalese sole (Solea senegalensis), another flatfish species. By quantitative real-time PCR analysis, PmTauT transcript was predominantly detected in liver and intestine, while was lesser expressed in gill and stomach. In addition, PmTauT in isolated turbot muscles was down-regulated by taurine in a dose-dependent manner. These results suggested that PmTauT was involved in taurine homoeostasis in turbot.

“…Although taurine can be synthesized from methionine and cysteine in some fish, the rate of synthesis may be inadequate to fulfil the taurine needs of fish fed an all-plant protein diet (Goto, Matsumoto, Murakami, Takagi, & Hasumi, 2003). But, taurine biosynthesis pathways in fish remain poorly described in the review of Salze and Davis (2015).…”

This study was conducted to evaluate the effect of dietary taurine supplementation on growth, immunity and resistant to dry stress of rice field eel (Monopterus albus) fed low fish meal diets. Six isonitrogenous and isolipid diets (32% fish meal) supplemented with six taurine concentrations (0, 0.3, 0.6, 0.9, 1.2 and 1.5 g/kg; designated as T 0 , T 0.03 , T 0.06 , T 0.09 , T 0.12 and T 0.15 groups, respectively) were prepared.A diet including 42% fish meal (FM group) was also included as a reference. The results showed that specific growth rate (SGR) in FM group was significantly higher than that in lower fish meal treatments. SGR significantly increased and slowly decreased with the increase in taurine supplementation level. Lipase activity value in intestine of M. albus fed FM diet was maximum, and with the increase in taurine supplementation level, lipase activity significantly increased and slowly decreased. The FM group had relative higher total antioxidant capacity (T-AOC) content, catalase (CAT), total superoxide dismutase (T-SOD), and lyzozyme (LZM) activities in serum than the other groups. With the increase in dietary taurine supplementation level, the CAT, T-SOD, T-AOC and LZM activities in serum significantly increased and then decreased. In the dry stress experience, the adrenaline (AD), cortisol (COR), glucose (GLU), total cholesterol (CHOL), and malondialdehyde (MDA) concentrations, T-AOC content, CAT and T-SOD activities in serum of M. albus in the four groups first increased and reached the peak at 2 hr, and then decreased under air-exposure stress. Compared to the FM group, T 0.15 group had relative higher T-AOC content, CAT and T-SOD activities, and lower AD, COR GLU, TC and MDA concentrations.
