Abstract

One way to support the increase of aquaculture production is to produce superior strains of growth. Carp as one of the potential for these commodities only rely on local strains which have had a decline in quality. For that, the effort to generate superior growth of carp need to be done. One way to do that is by hybridization. We carried out reciprocal crosses of 4 strains of carp Rajadanu, Subang, Majalaya and Kuningan to obtain 16 new strain candidates. Furthermore, growth test was conducted to find out the best candidate of the absolute and specific growth parameters. From these results, it was concluded that the absolute growth in length, weight, and the highest biomass obtained by crosses of SB x RD, the highest length and weight Specific Growth Rate obtained by crosses of RD x MJ. For the highest degree of survival is at the intersection of KN x SB, whereas the highest survival rate in the use of female parent KN. In the dominant male of female survival is the parent SB. The biggest positive heterosis character length growth values obtained by crosses of SB x RD. For the highest weight growth heterosis values obtained by crosses of SB x MJ. On the character of hatching, the highest positive heterosis values obtained by crosses of SB x MJ. The degree of survival of the highest heterosis values obtained by crosses of KN x MJ. On the character of the highest positive heterosis values of biomass obtained by crosses of SB x MJ. As for the character length SGR highest positive heterosis values obtained by crossing two directions of RD and SB. And for the character weight Specific Growth Rate, the highest positive heterosis values obtained by crossing two ways KN and MJ.

Abstract

Salah satu parameter lingkungan dalam budidaya ikan air tawar yang dapat berpengaruh terhadap pertumbuhan dan kelangsungan hidup adalah salinitas. Studi ini dilakukan untuk mengetahui respon pertumbuhan benih ikan gabus (Channa striata) dalam beberapa media dengan salinitas berbeda. Penelitian ini dilakukan di Balai Penelitian dan Pengembangan Budidaya Air Tawar, Bogor. Benih ikan gabus (panjang total: 4,89 ± 0,09 cm; bobot tubuh: 0,88 ± 0,05 g) sebanyak 50 ekor dipelihara per akuarium (dimensi: 40×30×40 cm) dengan sistem aerasi. Perlakuan salinitas yang diberikan yaitu 0, 5, dan 10 ppt, dengan masing-masing perlakuan terdiri dari 3 ulangan. Ikan dipelihara selama 21 hari dengan diberi pakan komersial 3% biomassa per harinya. Pertumbuhan, laju pertumbuhan spesifik, rata-rata pertumbuhan harian, dan sintasan benih ikan gabus merupakan beberapa parameter yang diamati. Hasil uji pertumbuhan benih ikan gabus menunjukkan bahwa pertambahan panjang dan sintasan antar perlakuan salinitas tidak berbeda nyata (P>0,05). Sedangkan pertambahan bobot, laju pertumbuhan spesifik, dan rata-rata pertumbuhan harian pada 0 ppt (0,53 ± 0,03 g; 2,32 ± 0,10 %/hari; 0,025 ± 0,001 g/hari) secara signifikan lebih tinggi dibandingkan dengan perlakuan 5 ppt (0,45 ± 0,03 g; 1,86 ± 0,10 %/hari; 0,021 ± 0,002 g/hari) dan 10 ppt (0,44 ± 0,01 g; 1,94 ± 0,03 %/hari; 0,021 ± 0,001 g/hari) (P<0,05). Hasil penelitian mengindikasikan bahwa peningkatan salinitas menurunkan pertumbuhan bobot, laju pertumbuhan spesifik, dan rata-rata pertumbuhan harian benih ikan gabus.
