Effects of dietary taurine supplementation to a casein-based diet on growth performance and taurine distribution in two sizes of juvenile turbot (Scophthalmus maximus L.)

Interactive effects of dietary taurine and glutamine on growth performance, blood parameters and oxidative status of Japanese flounder Paralichthys olivaceus

“…The effect of dietary Gln on Japanese flounder has not yet been reported, however it was reported that proper supplementation of Gln in diet can affect the growth performance of Jian carp (Lin and Xiao, 2006), red drum (Cheng et al, 2012) and hybrid sturgeon (Qiyou et al, 2011). In the present study, growth parameters increased when both dietary Tau and Gln levels increased, this might be partly explained by the increased trend of feed utilizations, which is consistent with previous studies on Tau in Japanese flounder and juvenile turbot separately (Kim et al, 2007;Qi et al, 2012) as well as Gln in Jian carp (Lin and Xiao, 2006). Nevertheless, both Tau and Gln were reported to stimulate the intestinal development of fish larvae Li et al, 2009;Salze et al, 2012), which could affect the growth of fish via promoting the structure and function of digestive organs.…”

“…HSI and VSI of Japanese flounder were not altered by either Tau or Gln in the current study which indicated that the dietary levels of Tau or Gln did not affect morphological index of this species. Similar results on oral administration of Tau were also found in turbot (Qi et al, 2012), where neither HSI nor VSI was affected by various levels of dietary Tau (from 0.16% to 1.66% of the diet), as well as HSI in rainbow trout (Gaylord et al, 2007). On the other hand, various levels of free dietary Gln did not alter the hepatosomatic index, condition factor or other tissue indices of juvenile channel catfish (Pohlenz et al, 2012).…”

“…Diets without taurine supplementation showed a decrease in FI as SBM inclusion increased, while taurine supplementation in diets positively affected FI. A stimulant effect of taurine on olfactory organs of fish has been observed in several species (Chatzifotis, Polemitou, Divanach, & Antonopoulou, 2008), and the present results on FI confirm that palatability increases significantly with taurine supplementation in diets containing SBM as has been previously reported for other fish species (Lunger, McLean, Gaylord, Kuhn, & Craig, 2007;Kim et al, 2005;Qi et al, 2012;Lim et al, 2013). Therefore, higher weight gain in fish fed SBM20+T and SBM40+T can be partly attributed to the increased feed intake.…”

Taurine supplementation in diet for olive flounder at low water temperature

“…Park et al (2002) and Kim et al (2007) reported that dietary taurine can significantly enhance the growth performance of juvenile Japanese flounder. The observations are similar to the results of juvenile yellowtail (Matsunari et al 2005) and turbot (Scophthalmus maximus) (Qi et al 2012). Growth rate and feed efficiency have been improved with taurine supplementation in European sea bass (Dicentrarchus labrax) (Brotons Martinez et al 2004), rainbow trout (Gaylord et al 2006), and black tiger shrimp (Penaeus monodon) (Shiau and Chou 1994).…”
