Pengaruh Fotoperiod Berbeda Terhadap Perkembangan Ovarium Ikan Cupang (Betta splendens)

Ikan cupang (Betta splendens) merupakan ikan hias dengan nilai komersial yang tinggi dan memiliki keistimewaan morfologi dengan nilai estetika. Pemintaan ikan cupang terus meningkat sehingga mendorong peluang budidaya ikan hias air tawar dengan mengembangkan teknologi dalam proses reproduksi. Cara memenuhi permintaan pasar ikan cupang dengan menggunakan cara manipulasi reproduksi salah satunya dengan metode fotoperiod. Tujuan penelitian mengetahui pengaruh perlakuaan fotoperiod berbeda terhadap perkembangan ovarium ikan cupang. Rancangan penelitian menggunakan rancangan acak lengkap dengan 3 perlakukan dan 5 ulangan. Ikan cupang yang di pelihara dengan perlakukan A (8 jam terang dan 16 jam gelap), perlakuan B (16 Jam terang dan 8 jam gelap) dan perlakuan C (12 jam terang dan 12 jam gelap). Lama pemeliharaan ikan cupang selama 40 hari. Kegiatan penelitian dilaksanakan di Laboratorium Sumberdaya Akuatik FPIK Unsoed. Hasil penelitian Anova menunjukkan perbedaan nyata (P<0,05) pada perlakuan 16L:8D, dengan tahapan oogenesis tertinggi (27,56 ±7,39%), Kesimpulan dari penelitian bahwa ikan cupang betina dengan perlakuan fotoperiod (16L:8D) dapat mempercepat proses kematangan ovarium pada ikan cupangBetta fish (Betta splendens) is an ornamental fish with high commercial value and has distinctive morphology with aesthetic value. The demand for Betta fish continues to increase, thereby encouraging opportunities for cultivating freshwater ornamental fish by developing technology in the reproduction process. One way to meet market demand for Betta fish is by using reproductive manipulation methods, one of which is the photoperiod method. The aim of the research was to determine the effect of different photoperiod treatments on the development of Betta fish ovaries. The research design used a completely randomized design with 3 treatments and 5 replications. Betta fish were kept in treatment A (8 hours light and 16 hours dark), treatment B (16 hours light and 8 hours dark) and treatment C (12 hours light and 12 hours dark). The length of time for keeping betta fish is 40 days. Research activities were carried out at the Aquatic Resources Laboratory of FPIK Unsoed. The results of the Anova research showed a significant difference (P<0.05) in the 16L:8D treatment, with the highest oogenesis stage (27.56 ± 7.39%). The conclusion from the research was that female Betta fish with photoperiod treatment (16L:8D) could accelerate the process of ovarian maturity in betta fish

MANAJEMEN SELEKSI INDUK DALAM PEMBENIHAN IKAN CUPANG DI SMK NEGERI 1 MEUREUBO ACEH BARAT

This service aims to provide knowledge to students of SMK Negeri 1 Meureubo, West Aceh about the management of parent selection in betta fish hatchery activities. Betta fish was a type of ornamental fish that was very popular among people from the top and bottom as well as from children to adults.
