Abstract
This study was conducted to evaluate the effects of dietary thiamin on the physiological status of the juvenile grouper Epinephelus coioides Graded levels of thiamin 008 050 212 315 463 1237 mg thiamin kg−1 diet were fed to grouper juveniles mean weight 1697 ± 014 g for 10 weeks Although fish fed the thiamindeficient TD diet showed no obvious symptoms of thiamin deficiency or increased mortality those fed the lowest doses of thiamin 008 and 050 mg thiamin kg−1 diet had significantly decreased transketolase activity in the liver In addition the level of liver thiobarbituric acid reactive substances in fish fed the TD diet was 33–67 higher than that in fish with the thiaminsupplemented diet There were no significant differences in superoxide dismutase activity between the different groups of fish
