Pemijahan dan Perkembangan Embrio Ikan Pelangi, Melanotaenia spp. Asal Papua
Abstract: Rainbow fish
(Melanoptaenia spp.) originated from Sungai Gelap of Papua. The objective of
this experiment was to know the fecundity, hatching rate and the rate of
embryogenesis. Total of 50 male and female broodstock measuring 10–15 cm reared
in closed recirculating water system in concrete tank until their gonad
matured. One pair composed of one male and two female’s of matured fish was
transferred to 1 x 1 x 0.5 m³ concrete tank for pair breeding, the fish was
sheltered with water hyacinth. Released eggs were observed in the morning and
in the afternoon daily. Eggs were categorized into fertile and infertile. Some
25 eggs were incubated in plastic baskets, and observed under microscope for
their embryonic development stages. The results showed that rainbow fish from
Sungai Gelap produced eggs (averages) 392 per female; fertility rate was
93.74%; average hatching rate was 87.36%, and the fertilized eggs were hatched
approximately 5 days incubation.
