Abstract
Arfak rainbowfish (Melanotaenia arfakensis) is one of the endemic fish of West Papua that can be found in river and lake systems in the Manokwari Regency. Currently, the status of the arfak rainbowfish is nearly extinct. Therefore, this study aimed to know the hatching rate and survival of arfak rainbowfish larvae that were naturally spawned. The results showed that the hatchability of arfak rainbowfish eggs reached 96.9% in A1 aquarium and 96.4% in A2 aquarium. The survival rate of arfak rainbowfish larvae in the A1 aquarium was 67.5%, while the A2 aquarium was 58.7%. The larval survival rate was relatively low. Therefore, further research is needed to increase the survival rate of arfak rainbowfish larvae.

Summary
Ikan pelangi arfak (Melanotaenia arfakensis) merupakan salah satu ikan endemik Papua Barat, Kabupaten. Ikan pelangi arfak atau dalam bahasa inggris disebut Rainbowfish merupakan jenis ikan hias. Masyarakat Suku Arfak dalam Bahasa Hatam menyebut ikan tersebut dengan nama “Anggicak”. Ikan pelangi arfak dapat ditemukan pada sistem sungai di Kabupaten Manokwari (Manangkalangi et al, 2018). Status konservasi ikan pelangi arfak yaitu terancam punah (Endangered) (Allen dan Kadarusman, 2020). Pola penyebaran populasi ikan pelangi arfak yang terbatas dan sangat rentan terhadap kepunahan akibat degradasi kualitas habitat alami. Salah satunya dengan mengkaji secara ilmiah teknik pemijahan ikan pelangi arfak secara alami. Informasi ini penting untuk menunjang pengembangan budidaya ikan pelangi arfak kedepanya. Tujuan dari penelitian ini yaitu untuk mengetahui daya tetas telur dan tingkat kelangsungan hidup larva ikan pelangi arfak yang dipijahkan secara alami
