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.

Abstract

Hatchery managers and maintaining genetic diversity and fitness population in endangered and threatened species in pond is a important and difficult thing to do.  But is must to do for conservation biology.  Fitness and structure population depends on effective breeding number (Ne) and population connectivity between each other. The second most important thing is gene flow and genetic drift. Ne is major role in the maintenance of genetic diversity as indicator for inbreeding depresion and genetic drift.  We sampled 6 hatchery in Jakarta  and Bekasi Indonesia region and used 12 polymorphic microsatellite loci to quantify population genetic structure. Result in this study are, each farm have different methode. The old farmers is bapak Gusi and bapak Hasan (+30 years).  Ne in bapak Hasan and bapak Gusi hatchery is 66,667 and F value is 0,00749 and loosing allele (P) is 0,26183.  Compared with younger farmers bapak Yahya (5 years) have Ne = 133,333, F = 0,00375 and P = 0,06855.  Even though hatchery bapak Hasan and bapak Gusi have the same value Ne, F and P but the result in population structure they are different founder populations. Hatchery bapak Hasan have unique structure and alleles composition compared with other hatchery.Keywords: breeding, management, Melanotaenia boesemani, hatchery, population.
