Abstract Funae fishery using fishing technology modified from skipjack pole-line fishery. However, the target of fishing remains similar i.e. Skipjack Tuna. The modification purpose is to reduce cost according to the financial capital owned by the local small-scale fisherman. How far this modification was done by the fisherman is the question which needs answer through this study. The study performed at Bunaken fishing base aimed at to learn and describe profile of funae fishery in term of boat performance, fishing gear, fishing operation process, income share system and financial analysis. Study performed based on survey method was primary data collected using interview with boat owners and his crews. While secondary data gathered from related institutions. The result of study indicated that the funae fishery is typical of small-scale fishery in term of smaller boat performance compared those of pole-line fishery, small size of gear, daily operation process mixed income share system and financially profitable fishery. Keywords: Profile, Business, Funae, Fishery Abstrak Usaha perikanan funae merupakan hasil modifikasi dari alat tangkap usaha perikanan Huhate. Walau demikian, target operasi penangkapan tetap sama yaitu ikan Cakalang dan Tuna. Tujuan modifikasi adalah penghematan biaya sesuai dengan kemampuan modal yang dimiliki oleh nelayan lokal. Sampai berapa jauh modifikasi itu dilakukan oleh nelayan merupakan pertanyaan yang membutuhkan jawaban melalui penelitian ini. Penelitian telah dilaksanakan di pangkalan perikanan desa Bunaken bertolak dari tujuan untuk mempelajari dan mengkaji proil perikanan funae melalui telaah beberapa variabel seperti penampilan perahu dan alat tangkap, proses operasi penangkapan, sistem bagi hasil, dan analisis keuangan. Penelitian dilaksanakan dengan menggunakan metode survei dimana data primer dikumpulkan langsung dari pemilik dan awak perahu. Sedangkan data sekunder diambil dari berbagai instansi terkait. Hasil penelitian menunjukkan bahwa perikanan funae adalah khas usaha perikanan skala kecil. Hal ini nampak dari penampilan perahu dan alat tangkap yang lebih kecil dibandingkan dengan usaha perikanan Huhate. Di samping alat tangkap kecil juga proses penangkapan harian, sistem bagi hasil campuran dan secara finansial memberi laba. Kata Kunci : Profil, Usaha Perikanan, Pancing, Funae
