“…Taurine is a conditionally essential nutrient that performs multifaceted roles in fish physiology. These roles include growth promotion (Lim et al, 2013), lipid digestion (Kim et al, 2008), antioxidant action (Han et al, 2014), neuroprotection (Lima et al, 2001) and detoxification (Hano et al, 2017). However, the biosynthetic capacity of taurine in many marine fish species is insufficient because the enzymes involved in its generation are either present at low levels or missing (Hano et al, 2017).…”

The effects of replacing dietary fishmeal by soybean meal with taurine supplementation on feed intake, growth, feed utilization, body composition and waste output of largemouth bass were examined. A control diet (C) contained 400 g/kg fishmeal, 20%, 40% and 60% of fishmeal in diet C was replaced by soybean meal, with or without 5 g/kg taurine supplementation (abbreviated as S20 + T, S40 + T, S60 + T, S20, S40 and S60, respectively). Significantly lower weight gain was found in fish fed diet S60 compared with fish fed diet C (p < 0.05), while no significant difference was found in weight gain between fish fed diet C and fish fed diets S20, S20 + T, S40 + T and S60 + T (p > 0.05). No statistically differences were found in feed intake and feed conversion ratio between fish fed diet C and fish fed diets S20, S20 + T, S40, S40 + T and S60 + T (p > 0.05). No significant differences were found in nitrogen retention efficiency, body crude protein content and nitrogen waste among fish fed different test diets (p > 0.05). This study suggests that dietary fishmeal level for largemouth bass can be reduced to 240 g/kg and further reduced to 160 g/kg with taurine addition, with soybean meal used as a fishmeal substitute.

“…Many studies proved that taurine is an essential nutrient for fish (Takagi et al 2008;Lim et al 2013; El-Sayed2014; Salze and Davis 2015) and involved in bile acid metabolism of fish (Goto et al 1996(Goto et al , 2017. Therefore, taurine enhances lipid metabolism of fish and improves the absorption of fat-soluble vitamins (Kim et al 2008;El-Sayed2014). A study conducted by Park et al (2002) indicated that dietary taurine was involved in a metabolism of sulfur amino acids of juvenile Japanese flounder (Paralichthys olivaceus).…”

Effects of taurine supplementation in low fish meal diets for red seabream (Pagrus major) in low water temperature season

Background: Taurine is a conditional essential amino acid for fish. A study was conducted to investigate the compensating effect of supplemental taurine in diets for red seabream (Pagrus major) on impaired growth performance by fish meal (FM) replacement with soybean meal (SM) at low water temperature (14.15 ± 1.95°C). Methods: A FM-based diet was considered as a high FM diet and three other experimental diets were formulated to replace FM with SM by 20, 35, or 50% (HFM, SM20, SM35, or SM50, respectively) without taurine and other four diets were formulated by adding 1% taurine to the diets (HFM-T, SM20-T, SM35-T, or SM50-T, respectively). Triplicate groups of fish (108.9 ± 1.58 g/fish) were distributed into 24 polyvinyl circular tanks (215 L) with 20 fish per tank and fed one of the diets to satiation for 20 weeks. Results: Growth performance and feed utilization of red seabream were significantly improved by the dietary taurine supplementation. SM20-T and SM35-T diets increased fish growth that are comparable to HFM diet. Feed intake, feed conversion ratio, and protein efficiency ratio of fish fed SM20-T and SM35-T diets were not significantly different from those of HFM group. Dietary taurine supplementation in each FM replaced group numerically increased innate immunity of the fish. Lysozyme and superoxide dismutase activities were significantly decreased in fish fed SM35, SM50, and SM50-T diets compared to those of fish fed HFM diet while they were not significantly lower in SM20, SM20-T, SM35, and SM35-T groups. Glutathione peroxidase activity was significantly lower in fish group fed SM50 diet while SM50-T group did not significantly lower compared to that of HFM group. The relative expression level of hepatic IGF-1 mRNA was improved in fish fed taurine-supplemented diets compared to their respective SM diets. Conclusions: Growth performance and feed utilization of red seabream can be accelerated or restored by 1% taurine supplementation when they are fed high level of SM up to 35% in diets during low water temperature season.

“…As in mammals, taurine plays important roles in many physiological processes in fish including bile salt conjugation [ 18 ], osmoregulation [ 19 ], and vision [ 20 , 21 ]. In addition, dietary taurine supplementation has been shown to stimulate growth in multiple fish species, such as rainbow trout [ 22 ]; Japanese flounder [ 18 , 23 ]; turbot [ 24 ]; red seabream [ 25 , 26 ]; cobia [ 27 , 28 , 29 , 30 , 31 ]; Atlantic salmon [ 32 ]; and yellowtail [ 33 ].…”

Taurine Biosynthesis in a Fish Liver Cell Line (ZFL) Adapted to a Serum-Free Medium

Although taurine has been shown to play multiple important physiological roles in teleosts, little is known about the molecular mechanisms underlying dietary requirements. Cell lines can provide useful tools for deciphering biosynthetic pathways and their regulation. However, culture media and sera contain variable taurine levels. To provide a useful cell line for the investigation of taurine homeostasis, an adult zebrafish liver cell line (ZFL) has been adapted to a taurine-free medium by gradual accommodation to a commercially available synthetic medium, UltraMEM™-ITES. Here we show that ZFL cells are able to synthesize taurine and be maintained in medium without taurine. This has allowed for the investigation of the effects of taurine supplementation on cell growth, cellular amino acid pools, as well as the expression of the taurine biosynthetic pathway and taurine transporter genes in a defined fish cell type. After taurine supplementation, cellular taurine levels increase but hypotaurine levels stay constant, suggesting little suppression of taurine biosynthesis. Cellular methionine levels do not change after taurine addition, consistent with maintenance of taurine biosynthesis. The addition of taurine to cells grown in taurine-free medium has little effect on transcript levels of the biosynthetic pathway genes for cysteine dioxygenase (CDO), cysteine sulfinate decarboxylase (CSAD), or cysteamine dioxygenase (ADO). In contrast, supplementation with taurine causes a 30% reduction in transcript levels of the taurine transporter, TauT. This experimental approach can be tailored for the development of cell lines from aquaculture species for the elucidation of their taurine biosynthetic capacity.
