“…Taurine is a DAA involved in key roles such as neurotransmitter modulation and synaptic activity (Huxtable, 1989). This AA is important to be present in the diets as it is thought to increase feed intake and enhance growth performance (Takagi et al, 2010;Pinto et al, 2013).…”

“…Digital images suggest that wax spray beads can be digested by rotifers, although the proportion of digested beads is likely a function of the lipids used to produce them. Liposomes were also successfully used as carrier systems to enrich live prey with hydrophilic or hydrophobic nutrients (Barr and Helland, 2007;Monroig et al, 2007;Ozkizilcik and Chu, 1994;Pinto et al, 2013;Saavedra et al, 2009), with results suggesting high availability of the carried nutrient. However, a direct comparison of digestibility of beads produced with different lipid types has not yet been conducted.…”

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.

“…Taurine was also seen to benefit gilthead seabream (Sparus auratus) larvae through an apparent sparing of Met for other metabolic processes (increasing Met retention in body tissue and free amino acid fractions with a related reduction in Met catabolism) (Pinto et al, 2013). …”

“…Tau is perhaps the most intriguing of the sulphur amino acids due to the variety of biological functions in which it is involved and the fact that the exact mechanism of its action is poorly understood. In mammals, it is known to play a role in the control of neurotransmitter and synaptic activity, calcium uptake and antioxidant protection of retinal rod outer segments (Pinto et al, 2013) as well as modulating osmoregulation, bile acid conjugation, membrane stabilisation and hormone release . Its bile acid conjugating action is important in the absorption of nutrients (Espe et al, 2010).…”

“…Tau supplementation of non-fishmeal based diets has been linked to improved growth in a number of fish species (Takagi et al, 2010;, however the exact mechanism of this stimulatory effect is so far unclear. One theory is that Tau may be sparing methionine (Met), a precursor and essential amino acid (EAA), for protein synthesis and other important physiological processes such as production of S-Adenosylmethionine (SAM) (Pinto et al, 2013).…”

Elucidation of the roles and requirements of sulphur amino acids in the diet of barramundi (Lates calcarifer)

With the increasing use of plant protein meals to replace fishmeal in aquafeeds, there is a concomitant need to properly characterise the requirements for individual amino acids in the diet of carnivorous fish species such as barramundi (Lates calcarifer). This may be especially important for methionine (Met) and taurine (Tau) which are known to be limiting in these ingredients. This project aimed to define the requirements for these nutrients for barramundi, as well as to elucidate some of the mechanisms underpinning any observed stimulatory effect on growth.The aim of the first experiment was to evaluate the methionine (Met) and total sulphur amino acid (TSAA) requirements of juvenile barramundi to act as a baseline for further study. A requirement for Met of between 10.5 (95% of maximum response) and 13.6g kg -1 (99% of maximum response) in a diet with 592g kg -1 CP and 6.6g kg -1 Cys (17.1-20.2g kg -1 TSAA; 1.8-2.3%CP Met + 1.1% CP Cys) was established. Additionally, it was concluded that at least 40% of concluded that taurine appears to be conditionally essential to barramundi.
