Abstract
Vitamin C is a water-soluble compound that can involve in the repair of tissue and the enzymatic production of certain neurotransmitters. The aims of the present study were the evaluation of the effects of vitamin C on the growth performance and survival rate of Pharaoh Cuttlefish (Sepia pharaonis) for 25 days. Sepia pharaonis were randomly allocated in 20 aquaria (21 fish per tank) and triplicate groups of Sepia pharaonis (initial weight 4.5±0.11g) were fed with supplemented Biomar feed. The larvae in the control treatment were fed without Biomar. The larvae in the experimental treatment were fed with Biomar in addition to vitamin C. The results clearly showed that in fish fed vitamin C, body weight had significantly increased in comparison to control treatment (P>0.05). Also, vitamin C had a positive effect on fish survival rate there was no significant difference between treatments. The best results on survival rate were obtained by feeding vitamin C which had a great effect on the survival of this species in captivity.
