Effect of glycyrrhizic acid on growth performance in European sea bass (Dicentrarchus labrax) juvenile

The aim of this study was to investigate the effects of glycyrrhizic acid (GA) on european sea bass (Dicentrarchus labrax) growth performance. In this study 100-day sea bass juveniles were used and fishes were fed with 4 different diets which supplemented with GA [0 ml.kg-1 (Control), 2 ml.kg-1, 4 ml.kg-1, 6 ml.kg-1]. Each diet was fed to triplicate group of fish (5,6±0,3 cm; 1,6±0,2 g). After 30 days feeding period, growth performance, survival rate, feed conversion ratio (FCR), specific growth rate and were investigated. At the end of feeding trial, results showed significant differences in growth performance and FCR (p<0.05) between both 4 ml.kg-1, 6 ml.kg-1 groups and other groups. However, survival rate and specific growth rate showed no significant differences (p>0.05). As a result, it was determined that GA application at 4 and 6 ml.kg-1 affected significant increases and positive developments in growth in sea bass juveniles.
