Disamping para peneliti lainnya yang turut serta dalam mengamati dan para teknisi yang turut serta melaksanakan kegiatan dalam menghasilkan ikan nila BEST.

Nila BEST belum dijual secara komersial

Untuk diketahui oleh masyarakat pembudidaya perikanan secara umum, bahwa sampai dengan saat ini ikan Nila BEST belum disebarluaskan secara komersial ke masyarakat, kecuali untuk keperluan pengujian dan pengamatan secara terbatas atas persetujuan dan monitoring langsung dari Peneliti dan Institusi yang berwenang, yaitu Dr. Ir Rudhy Gustiano, Otong Zenal Arifin, SPi, MSi dan Gleni Hasan Huwoyon, SPi dari Balai Riset Perikanan Budidaya Air Tawar Sempur Bogor. Demikian untuk diketahui.

Growth Performance of the “BEST” Strain Under Communal and Separate

Growth Performance of the “BEST” Strain and NIFI Under Communal and Separate Rearing Test

ABSTRACT
Generaly the common cultured nile tilapia are represented by the black and red phenotypes. In many species, color has a pleiotropic effect on the growth performance as well as their commercial price. The objectives of the study was to elucidate the growth performance of the “BEST” (black nile tilapia) and NIFI (red nile tilapia) strain under communal and separate rearing test. In the study fish with 4-5 cm sized in length were used. In communal test (experiment 1), fish were reared in 1 m3 fine net placed in concrete tank with density 80 fish/net (40 fish for each strain) with four replications. In separate rearing test (experiment 2), fish were reared with density 65 fish/net with four replications for each strain. During the experiment, fish were fed with commercial pellet 5% body weight a day. Observation on the growth was conducted every 10 days by weighting the 30% of population for each strain. The results showed that in experiment 1, the BEST strain has better growth performance than NIFI one (P<0,01) for absolute growth (BEST: 8,0 ± 0,88; NIFI: 3,6 ± 0,72) and spesifik growth rate (BEST: 0,2 ± 0,02; NIFI: 0,1 ± 0,02). The significant different (P<0,01) was started on the third sampling. In the experiment 2, the BEST strain has better absolute and spesific growth than NIFI (P<0,01) with absolute growth (BEST: 5,4 ± 0,96; NIFI: 2,8 ± 0,36), and specific growth rate (BEST: 0,18 ± 0,035; NIFI: 0,09 ± 0,013). Significant different was exist on the second sampling.
