Taurine supplementation to alternative dietary proteins used in fish meal replacement enhances growth of juvenile cobia (Rachycentron canadum)

Physiological roles of fatty acyl desaturases and elongases in marine fish: Characterisation of cDNAs of fatty acyl Δ6 desaturase and elovl5 elongase of cobia (Rachycentron canadum)

“…Interestingly, and in contrast to salmonids, cobia do not appear to develop soybean mealinduced enteritis in the distal intestine (Romarheim et al, 2008). Similarly, replacement of fish meal with yeast protein reduced growth performance in cobia juveniles (Lunger et al, 2006(Lunger et al, , 2007. It is against this background that the present work, investigating PUFA metabolism and HUFA synthesis in cobia, is set.…”

“…Similar results have been previously reported, whereby the inclusion of taurine to all plant protein diets improve the growth performance in other carnivorous marine organisms, because they are either unable or poorly able to synthesize enough taurine to fulfill their nutritional needs . Therefore, taurine supplementation is necessary in diets that are either partially or totally substituted with plant protein (Lunger, McLean, Gaylord, Kuhn, & Craig, 2007;Goto, Tiba, Sakurada, & Takagi, 2001;Kim et al, 2005;Takagi et al, 2006). Studies in mangrove red snapper (L. argentimaculatus) and spotted rose snapper (L. guttatus) have shown that FM protein can be replaced by up to 24% and 20% with soybean meal protein without taurine supplementation, respectively (Benetti et al, 2002;Silva-Carrillo, Hernández, Hardy, González-Rodríguez, & CastilloVargasmachuca, 2012).…”

“…Increasing evidence indicates that some marine fish have a conditional requirement for taurine. In fish, the ability to synthesize taurine varies depending on species and age, due to differences in enzyme activity in taurine biosynthesis and during ontogenesis (Salze & Davis, 2015 species of larval and juvenile fish, including cobia (Rachycentron canadum) (Lunger, McLean, Gaylord, Kuhn, & Craig, 2007) Japanese flounders (Paralichthys olivaceus) (Kim et al, 2008), yellowtail (Seriola quinqueradiata) (Khaoian, Nguyen, Ogita, Fukada, & Masumoto, 2014) and totoaba (Totoaba macdonaldi) (Bañuelos-Vargas, López, Pérez-Jiménez, & Peres, 2014). 2014), with results suggesting that taurine may be essential to promote optimum growth.…”

“…are not yet understood, the addition of taurine to the diet can improve the growth of important marine aquaculture species such as olive flounder Paralichthys olivaceus (Kim et al 2005), red sea bream (Matsunari et al 2008), and cobia Rachycentron canadum (Lunger et al 2007) as well as some freshwater species such as rainbow trout Oncorhynchus mykiss (Gaylord et al 2006). While ample amounts of taurine are found in many animal proteins, including fish meal, taurine is absent from terrestrial plants.…”
