“…Fry production and survival can be enhanced by feeding the broodstock with supplemental diets (Santiago et al, 1991). Vitamins are likewise needed for proper reproduction in fish; this has been documented for vitamin A, E and C (Sandnes et al, 1984;Watanabe, 1985;Soliman et al, 1986;Lie and MangorJensen, 1993;NRC, 1993). Dietary additives e.g.…”

An experiment was conducted to observe growth performance and survival of the larvae produced from the brood fish of Ompok pabda treated with 4 dietary levels of vitamin E for 90 days viz. 0 (served as control), 50, 100 and 150mg vitamin E/kg feed under 4 treatments i.e. treatment T 1 , T 2 , T 3 and T 4 . After the feeding trials, the brood fish were induced to breed with equal dose of PG extract i.e. 12 and 18mg/kg body weight for male and female respectively and subsequently larvae were produced. The experiment was started with 5 days-old larvae having an average weight and length of 21.4 ± 8.6 mg and 13.8 ± 2.49 mm respectively in 16 bowls of 10l capacity divided into 4 treatments corresponding to the broods fish having 3 replications each with 100 larvae in each bowl i.e. 10 larvae per liter. After rearing for 28 days with live-food tubificid worms the highest growth rate in terms of weight (609.13 ± 15.20 mg) and length (86.70 ± 1.84 mm), gain in weight (587.78 ± 15.27 mg) and length (72.98 ± 1.81 mm), specific growth rate (30.36 ± 0.12%), health condition (16.63 ± 0.69 mg/mm) and survival (83.25 ± 2.87) were showed by the larvae produced from brood fish fed with 100 mg vitamin E/kg feed (treatment T 3 ) while poorest was observed by the larvae produced from brood fish fed 150 mg vitamin E/kg feed. The results imply that inclusion of 100mg vitamin E/kg feed in the diet of O. pabda brood fish is best for enhancing growth and survival of larvae indicating that vitamin E has a positive impact. The results also suggest that inclusion of higher level of vitamin E in the diet exerts an antagonistic effect on the produced larvae.

“…According to Kjørsvik et al (1990), the biochemical composition of fish gonads has a major influence on egg quality, since the gonads contain all the nutrients for the eggs. Other authors suggested earlier that vitamins and essential fatty acids (EFA) are of great importance to egg quality in both freshwater and marine fishes (Takeuchi et al 1981;Soliman et al 1986). It is also documented that ARA and DHA are accumulate in ovarian polar lipids during maturation , and optimising egg arachidonic acid (20:4 n-6) (ARA), eicosapentaenoic acid (20:5 n-3) (EPA) and docosahexaenoic acid (22:6 n-3) (DHA) contents and their mutual ratios is important for embryonic development and larval survival .…”

Two groups of Anguilla japonica were treated with hormone, one on a weekly basis, the other on a biweekly basis. Intramuscular injection was applied at a dose of 0.75 mg/kg BW carp pituitary extract (CPE) plus 150 IU/kg BW human chorionic gonadotropin (hCG) for female fish, while males received half of this dose. The average total lipid content of the gonads from the weekly treated group, i.e. 20.6 ± 1.2 % for females and 18.0 ± 2.3 % for males, was significantly higher than the biweekly treated group, 16.8 ± 0.7 and 15.5 ± 1.3 %, respectively (p \ 0.05). For both muscle and liver, the readings were not significantly different. The gonads from the weekly treated fish had more fatty acids, particularly saturated fatty acids, polyunsaturated fatty acids, highly unsaturated fatty acids, eicosapentaenoic acid (20:5n-3, EPA), docosahexaenoic acid (22:6n-3, DHA) and arachidonic acid (20:4n-6, ARA). Histological examination showed that the ovaries of both the weekly and the biweekly treated fish were mainly at stage IV. However, the weekly treated females had bigger oocyte diameter (722.0 ± 60.9 lm) than the biweekly females (611.6 ± 22.6 lm). These results suggest that CPE and hCG promoted the maturation process for both scheduled induction and that the frequency of hormone injection influenced the biochemical composition of gonads, especially their lipids. Our study describes for the first time the effect of hormone injection frequency on the lipid content and fatty acid composition in the gonads of A. japonica during artificial maturation.

“…Vitamin C affects hormone synthesis, vitellogenesis, and results in variable oocyte AA retention and gamete quality [10]. 1250 mg/kg of Ascorbic acids improves the hatchability of Oreochromis mossambicus [11]. A dietary level of 375 mg AA/kg diet was suggested to near saturate the ovaries and optimize the reproductive performance of rainbow trout (Oncorhynchus mykiss) which was eight times higher than the level suggested the national research council.…”
