Abstract

The fish’s reproduction status is affected by both fed compositions and vitamins intake lead to determine improvement of eggs quality as well as fish production. The presence of Ascorbic Acid (AA) in the cultivation ponds, might accelerate female’s gonad maturation and so rematuration. The research aimed to determine: (1) Level gonad maturity of supplementation Ascorbic Acid; (2) Oocyts diameter; (3) Larvae survival rate. The research used experimental methods.The method was a completely randomized design (CRD) of 4 treatments and 4 replications. Treatments were supplementation of AA at different dosages of 0, 600, 1200 and 1800 mg/kg fish-fed ration.The gonad maturity level was analysed descriptively and oocyte diameter and larvae survival rate data were analysed by ANOVA. The result showed that supplementation of AA at a dosage of 1200 mg / kg fish-fed ration accelerated the process of gonad maturity, development of oocyt diameter and larvae survival rate as well as the viability of O. vittatus larvae at 90 rearing days. In this case, level IV gonad maturity was reached at 90 days which characterized by completed vitelogenesis process and oocyte diameter of 1.1 mm. Thus, this study useful for aquaculture science by provide information on utilization of ascobic acid as food supplement in fish culture and also for fish farmer who wish to accelerate O. vittatus reproduction.

Highlights

Gonads maturity of adult female fish is determined by either environmental or genetic aspects
Vitamin C (Ascorbic Acid/ascorbic acid (AA)), one among those micro nutrients, supposed to present in the fish fed, since this compound has significant role on fish reproductive status and must be present in the fed since they do not have these in nature
The AA needs to be added on on the feeding rations of this fish (Ibrahem et al, 2010) whereas, the third one received a balanced diet supplemented with vitamin C

Summary

Introduction

Gonads maturity of adult female fish is determined by either environmental or genetic aspects. Nutrition as well as fed components like fats, amino acids, minerals, and vitamins might play significant role in affecting the fish reproduction phase ) (Canyurt & Akhan, 2008). The AA needs to be added on on the feeding rations of this fish (Ibrahem et al, 2010) whereas, the third one received a balanced diet supplemented with vitamin C Supplementation of AA on the fish-fed ration during ovum development in the ovarium may increase the ova hatching rate and fish larvae development (Sandnes, 1991)
