%X The aim of this study was to evaluate the effect of vitamin C L-ascorbate 2-triphosphate (LATP-Ca)on Indian major carp rohu (Labeo rohita) (Hamilton) during intensive aquaculture. Rohu were fedwith vitamin C (LATP-Ca) supplementation at doses of D1 (control) and D2 (500 mg/kg) diet for 10weeks. The effects were assessed by comparing the treated groups of fish to that of control group.Vitamin C (LATP-Ca) supplementation exerted significant (P<0.05) effects on oocyte developmentof rohu (Labeo rohita). A number of distinct developmental stages of oocyte can be delineated andoocyte growth in major carp rohu (Labeo rohita) found in two distinct phases; primary growthphase (PGP) and the secondary growth phase (SGP). In PGP, oogonia, chromatin nucleolus, earlyand peri nucleolus stage oocyte with Balbiani¡¯s vitelline body were observed while two types ofinclusions, lipid and protein, respectively were formed during vitellogenesis in the SGP. SGPdevelopment was found for a short period of time as compared to PGP. Similarly, development ofoocyte was very poor in fish fed with controlled diet.
