The effectiveness of adding oodev and melatonin through feed in increasing the productivity of clownfish broodstock (Amphiprion sp.) in BBPBL Lampung

Abstract

One of the most popular seawater ornamental fish commodities is the clownfish. The high market demand needs to be balanced with aquaculture activities to maintain the availability of clown fish in nature due to human exploitation. This study aims to evaluate the reproductive performance of clownfish broodstock by administering a combination of Oodev and melatonin through the feed. Treatment with K code is without Oodev and melatonin, O code is Oodev 1 mL/kg of feed, OMA code is Oodev 1 mL/kg + melatonin 0.5 mg/kg of feed and OMB code is Oodev 1 mL/kg + melatonin 1 mg/kg of feed. The number of broodstock used was 12 pairs with a weight range of 7–8 g/fish for males and 17–18 g/fish for females. Fish are fed twice a day with a limited feeding dose of 3% during maintenance. The parents used were productive broodstock that had just after spawning or the gonads did not contain eggs. Results showed that the addition of a combination of Oodev and melatonin could increase spawning frequency, accelerate spawning time, increase the number of eggs in the female parent, and obtain higher income compared to the control and Oodev treatment without melatonin. All parameters showed that the 1 mL/kg Oodev treatment + 0.5 mg melatonin (OMA) was the best.
