Taurine (2-aminoethanesulfonic acid, Tau) exists naturally in animals, including mammals, birds, fish and aquatic invertebrates (Salze & Davis, 2015). Tau derives from methionine via cysteine, and man, monkeys and cats have low activity of the enzyme cysteine sulfinic acid decarboxylase that controls the transport rate of Tau (Kim et al., 2008). Therefore, Tau needs to be obtained from dietary sources (Schuller-Levis & Park, 2003). Physiological functions of animals are affected by Tau. Previous studies have shown that animal growth performance is positively affected by dietary Tau levels (Li et al., 2009), for example, in piglets (Liu et al., 2014), larval turbot Scophthalmus maximus (Qi et al., 2012), sea bass Dicentrarchus labrax
