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.

Tanaman obat telah banyak digunakan sebagai bahan pencegah dan pengobatan penyakit pada ikan budidaya. Penelitian ini ditujukan untuk mengetahui status kesehatan ikan lele (C. gariepinus) yang menerima pakan dengan suplemen tanaman obat kombinasi dari daun sirih, jambu biji, dan kipahit melalui pengamatan gambaran darah dan histologi ginjal sebagai organ yang memproduksi darah. Kombinasi satu merupakan kombinasi dari ketiga daun tanaman obat masing-masing sebanyak 33%, kombinasi dua juga terdiri dari daun sirih, jambu biji, dan kipahit masing-masing sebanyak 5%:19%:76%, dan kontrol yaitu pakan tanpa penambahan tanaman obat. Gambaran darah dan histologi ginjal diamati pada minggu ketiga setelah pemberian pakan. Hasil pengamatan gambaran darah menunjukkan bahwa terdapat peningkatan jumlah sel darah merah pada ikan yang menerima pakan perlakuan dibandingkan dengan kontrol (0,4 ± 0,14). Namun tidak terdapat perbedaan nyata antara jumlah sel darah merah dari kelompok perlakuan kombinasi satu dan dua (1,5 ± 0,17 dan 1,4 ± 0,1). Jumlah sel darah putih pada kelompok perlakuan juga meningkat dibandingkan dengan kelompok kontrol (10,5 ± 0,46), namun tidak terdapat perbedaan nyata antara kelompok perlakuan kombinasi satu dan dua (15,1 ± 1,19 dan 17,6 ± 1,14). Hasil pengamatan histologi terlihat jaringan hematopoietik organ ginjal dari kelompok yang menerima perlakuan berproliferasi lebih banyak dibandingkan kelompok kontrol. Namun tidak ada pengaruh pada nilai hemoglobin dan persentase leukosit diferensiasi antara kelompok perlakuan dan kontrol. Penambahan daun tanaman obat dalam pakan ikan mampu meningkakan status kesehatan dari ikan lele.Medicinal herbs have been traditionally used as prophylactic and therapeutic supplement to treat diseases in aquaculture. This study was aimed to improve the health quality of catfish (C. gariepinus) through feeding on diets enriched with a combination of betel, guava, and tithonia as medicine by analyzing hematology and histology of kidney as blood producing organ. Diet-one was feed enrich with 33% of each plant. Diet-two was feed enriched with betel, guava, and tithonia at a proportion of 5%,19%, and 76%, respectively. Control diet was fed without the plants’ supplementation. Hematology and histology of fish kidney were observed after fish received three-week feed treatments. The results showed that there was an increase of erythrocyte levels in the treated fish groups fed with diet-one and diet-two compared with the control (0.4 ± 0.14). However, no significant differences of erythrocyte level were observed between fish groups fed with diet -one and die-two (1.5 ± 0.17 and 1.4 ± 0.1). Leucocyte levels also increased in the treated fish group with diet-one and diet-two compared to the control (10.5 ± 0.46). However, there was no significant difference of leucocyte level between the fish group feed with diet-one and diet-two (15.1 ± 1.19 and 17.6 ± 1.14). Histological observations found that there were more hematopoietic tissues in the fish kidney of proliferated treated group than the control group. However, there was no effect on hemoglobin level and leukocyte percentage differentiation between the treatment and control groups. This study concludes that medicinal herbs as enrichment ingredients in fish diet can increase the health quality of fish.
