Potret Profil Manajemen Hatcherypada Pembudidaya Ikan Pelangi Melanotaenia boesemani(Allen & Cross, 1980) di Kawasan Jakarta
International audience; 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 bapakGusi and bapakHasan (+30 years). Ne in bapakHasan and bapakGusi hatcheryis 66,667 and F value is 0,00749 and loosing allele (P) is 0,26183. Compared with younger farmers bapakYahya (5 years) have Ne = 133,333, F = 0,00375 and P = 0,06855. Even though hatchery bapakHasan and bapakGusi have the same value Ne, F and P but the result in population structure they are different founder populations. Hatchery bapakHasan have unique structure and alleles composition compared with other hatchery.; Manajemen hatchery penting untuk mempertahankan keragaman genetik dan kebugaran populasi dari spesies langka dan terancam punah di pembudidaya dan hal ini sulit dilakukan, tetapi menjadi keharusan untuk biologi konservasi. Kebugaran dan struktur populasi tergantung pada efektif breeding number (Ne) dan konektivitas populasi antara satu sama lain serta aliran gen dan pergeseran genetik. Ne memiliki peran utama dalam pemeliharaan keanekaragaman genetik dan sebagai indikator terjadinya inbreeding dan pergeseran genetik. Terdapat 6 hatchery sampel di wilayah Jakarta dan Bekasi Indonesia dengan menggunakan 12 lokus mikrosatelit polimorfik untuk mengukur struktur genetik populasi. Hasil penelitian ini menunjukkan bahwa masing-masing hatchery memiliki metode yang berbeda. Pembudidaya paling lama adalah bapak Gusi dan bapak Hasan (30 tahun). Ne di hatchery bapak Hasan dan bapak Gusi adalah 66.667 dan nilai F adalah 0,00749 dan nilai kehilangan alel (P) adalah 0,26183. Dibandingkan dengan pembudidaya bapak Yahya (5 tahun) memiliki Ne = 133.333, F = 0,00375 dan P = 0,06855. Meskipun penetasan di hatchery bapak Hasan dan bapak Gusi memiliki nilai Ne, F dan P yang sama, tetapi hasil struktur populasinya adalah populasi pendiri yang berbeda. Hatcheri bapak Hasan memiliki struktur yang unik dan komposisi alel dibandingkan dengan pembenihan lainnya.
