“…In fish species, the capacity for taurine synthesis is species-specific, and in highly carnivorous species such as bluefin tuna Thunns thynus, yellowtail, Japanese flounder Paralichthys olivaceus, and red sea bream it is markedly low or negligible [13,14]. In addition, the taurine requirement of yellowtail [37] and Japanese flounder [38,39] juveniles fed FM-based diets is more than 10 mg/g diet and about 15 mg/g diet, respectively, and for juvenile red sea bream fed a casein-based diet, it is 5 mg/g diet [40]. It is reported that dietary taurine supplementation improved growth performance of glass eel Anguilla anguilla [41] fed casein-based diets, and of cobia Rachycentron canadum [42], European sea bass Dicentrarchus labrax [43], and common dentex Dentex dentex [44] fed diets where FM was partially replaced with alternative protein sources.…”
