EFFECT OF VITAMIN C DIETARY SUPPLEMENTATION ON GROWTH AND SURVIVAL OF GREY MULLET, MUGIL CEPHALUS (LINNAEUS, 1758) FRYSAMBID SWAIN, N.K. CHADHA, J.K. SUNDARAY, P.B. SAWANT AND E.M. CHHANDA PRAJNADARSINIAbstract The present study was conducted to examine the effect of dietary supplementation of vitamin C on growth performance and survival of Mugil cephalus juveniles. Mullet juveniles of an average weight of 3.5 gm each were distributed into four treatment groups and were fed with one of the ten purified diets for 45 days. The growth performance and survival of the experimental animals were measured fortnightly. The experimental purified diets were formulated to contain with or without graded levels of vitamin C. The growth performance (absolute growth, percentage weight gain, SGR, PER, per day growth) were significantly higher in mullets fed with diet containing vitamin C supplementation than fed without vitamin supplementation. The vitamin had no significant effect on survival of the mullet juveniles and all the treatments were significantly similar to each other. These finding can be used for formulation of species specific feed for mullet fry for ensuring optimum growth
