Feeding Broodstock on a Diet Containing Vitamin E and Fish Oil Improve Eggs and Larval Quality of Nile tilapia (Oreochromis niloticus)
The experiment was conducted to determine the effect of dietary vitamin E and n-3 fatty acids on the gonad maturation, egg and larva quality of Nile tilapia. Fish were treated by various combinations of dietary dosage of vitamin E (50, 100, 150, and 200 mg/kg feed) and fish oil (10, 20, 30, and 40...

| description |
The experiment was conducted to determine the effect of dietary vitamin E and n-3 fatty acids on the gonad maturation, egg and larva quality of Nile tilapia. Fish were treated by various combinations of dietary dosage of vitamin E (50, 100, 150, and 200 mg/kg feed) and fish oil (10, 20, 30, and 40 g/kg feed). Three hundreds and twenty pairs of broodstock fish (female at stage of maturity II) were selected and used for this experiment. Fish were fed on the experimental diets three times a day at satiation. The tested of parameters such as gonad somatic index, egg diameter, fecundity, number of spawned fish, hatching rate, and survival rate. Results of the experiment indicated that supplementation of vitamin E and fish oil stimulated gonad development and increased fecundity, hatching rate and survival rate of Nile tilapia larva. Combination of vitamin E 150 mg/kg feed and fish oil 30 g/kg feed significantly improved egg and larva quality of Nile tilapia. Thus, combination of vitamin E in 150 mg/kg diet with fish oil in dose 30 g/kg diet give the best reproduction performance.

ABSTRAK
Penelitian ini dilakukan untuk mendapatkan kadar kombinasi vitamin E dan asam lemak esensial n-3 untuk pematangan gonad, kualitas telur dan larva ikan nila. Adapun dosis dari masing-masing perlakuan terdiri dari 4 taraf. Untuk vitamin E yaitu: 50 mg/kg, 100 mg/kg, 150 mg/kg, dan 200 mg/kg pakan sedangkan minyak ikan yaitu: 10 g/kg, 20 g/kg, 30 g/kg dan 40 g/kg pakan. Ikan uji yang digunakan sebanyak 320 ekor induk betina dan 320 ekor induk jantan dan diseleksi. Setiap hari ikan diberi pakan uji 2 kali sehari (pagi dan sore) secara at satiation. Selama periode pemeliharaan parameter yang diamati meliputi: indeks gonad somatik, diameter telur, fekunditas, jumlah induk yang memijah, derajat tetas telur, dan ketahanan hidup larva. Hasil penelitian ini menunjukkan bahwa pakan dengan kombinasi dosis vitamin E 150 mg/kg dan minyak ikan 30 g/kg memberi respons terhadap perkembangan gonad, fekunditas, derajat tetas telur dan ketahanan hidup larva ikan nila. Kombinasi vitamin E 150 mg/kg dan minyak ikan 30 g/kg pakan memberi pengaruh signifikan dalam meningkatkan kualitas telur dan larva ikan nila. Dengan demikian, kombinasi vitamin E 150 mg/kg dan minyak ikan 30 g/kg pakan adalah memberi hasil terbaik pada performa reproduksi.
