“…Taurine level of Domestic LT was rather lower than the others. Essentiality of dietary taurine has not been established in turbot, but available literature suggest that dietary supplementation of taurine increased growth and feed utilization performance in turbot fed either caseinbased (Qi, Ai, Mai, Xu, Liufu, Yun & Zhou 2012) or plant protein containing diets (Yun, Ai, Mai, Xu, Qi & Luo 2012). Apparently Domestic LT could meet the requirement of turbot for taurine, but when it is used as control protein base in assessment of alternative ingredients; higher levels of dietary taurine supplementation than other FMs may be required.…”

This study was conducted to evaluate nutritional values of selected commercial fish meals (FM) with two experiments in diets of turbot. In experiment I, five diets based on two Peruvian anchovy meals (one is a flame-dried FM: Peru-1 and the other steam-dried FM: Peru-2), a Danish FM (Danish LT), a domestic anchovy LT meal (Domestic LT) and an Alaskan white FM (WFM) as major protein source were formulated to contain 56% protein.The diets were fed to fish with an initial average weight of 119.4 AE 0.1 g for 9 weeks. Growth rate, feed utilization, whole body and visceral compositions, nitrogen, lipid and energy balances did not significantly change in Experiment 1 among the treatments. In Experiment 2, four diets based on three FMs (Domestic LT, Danish LT and Peru-1) and their mixture (Mix FM) were formulated to contain 50% protein and fed to triplicated groups of fish with an average initial weight of 51.4 AE 0.1 g for 6 weeks. Once again, there were no significant differences in growth rate and feed consumption among the treatments. However, fish on Mix FM diet had significantly better FCR and PER than the others. The results of two experiment indicated that Danish LT and Domestic LT were better in terms of phosphorus (P) retention and losses than two Peruvian FMs and WFM, suggesting that although different sources of FMs were comparable in terms of growth and feed utilization, they could lead to substantial differences in environmental impacts.

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.

“…Additionally, a limited number of studies report changes in body composition in response to dietary taurine levels: although due caution should be exerted when comparing studies using different species, diet matrices, and husbandry conditions, there is a general trend of decreasing body lipid content in response to limiting levels of dietary taurine(Espe et al, 2012a;Lunger et al, 2007;Qi et al, 2012;Salze et al, 2014b;Yun et al, 2012). However, the opposite trend have been observed in different species such as Atlantic salmon(Espe et al, 2012a;Espe et al, 2012b) and rodents (Tsuboyama-Kasaoka et al…”

Taurine: a critical nutrient for future fish feeds

Taurine is a sulfonic acid found in high concentrations in animal tissues. In recent years, a number of studies have demonstrated the essentiality of dietary taurine for many commercially relevant species, especially marine teleosts. Consequently, the removal of taurine-rich dietary ingredients such as fishmeal may create a deficiency, of which symptoms include reduced growth and survival, increased susceptibility to diseases, and impaired larval development. These symptoms emphasize the systemic role of taurine in the animal's physiology and provide few clues as to the underlying mechanisms of taurine function. In fact, a myriad of roles have been attributed to taurine in mammals, ranging from bile salt conjugation to membrane stabilization, osmoregulation, anti-oxidation, immunomodulation, calcium-signaling, and neuroprotection. This review describes the current knowledge of taurine physiology and metabolism in fish and requirement levels in relevant species, and highlights possible parallels with mammalian taurine metabolism. In addition, the effects of ingredient processing and feed manufacturing on taurine bioavailability are discussed. Finally, regulatory aspects are brought to the forefront: although the supplementation of taurine will be necessary to further reduce the use of ingredients such as fishmeal, taurine is not currently approved by the FDA in the USA for fish feeds.Obtaining approval in the United States to utilize taurine in fish feeds can improve the environmental and economic sustainability of fish feeds nation-wide.
