Abstract

trisignatus) together with live food for three spotted frog fish larvae. Breeding of three spotted frogfish was attempted using four feeds such as freshwater prawn (Macrobrachium rosenbergii), vannamei shrimp (Litpopenaues vannamei), white baits and capelin. Frog fishes fed with with vannamei, freshwater prawn and white baits released mass of unfertilized eggs, which settled at tank bottom. Frog fishes fed with capelin had eggs attached to the dorsal side of female frogfish after successful mating. It was found that capelin had positive effects on breeding. Fecundity of frog fish was 66. Eggs were white in colour for first two days and later changed to dark colour. The eggs started hatching after a period of twenty five days and hatching was completed in 25 days. Hatchlings were black in colour and had clearly visible orange red coloured yolk sac. Hatchlings mostly stayed at the bottom of the tank and had rare upward swimming movements. Yolk sac absorption was complete in one week. Frog fish juveniles were fed with enriched artemia nauplii for first one week after yolk absorption. As the babies started growing, they were fed with two days old artemia naulplii and later with adult artemia. This study showed the importance of feed in successful breeding of three spotted frog fishes and successful larval rearing was done with live artemia. Breeding of frog fishes will help to increase the trade in aquarium industry by conserving the wild stock.
