PENGARUH PEMIKAT CAHAYA BERKEDIP PADA BUBU TERHADAP HASIL TANGKAPAN IKAN KARANG (The Effect of Blinking Light Attractor on Trap Toward the Capture of Coral Fishes)

Abstract

ABSTRACT
This study was aimed at observing the influence of blinking light attractor of trap on the coral fish catch and identifying the catch species. It was carried out in the coastal waters of Kampung Ambon, East Likupang district, North Minahasa Regency using an experimental method. Data were collected using 6 iron-framed fish traps of net wall and operated for 6 days. Three units had Mackerel and blinking light, and the other three used only Mackerels as bait.

Penelitian ini bertujuan untuk menentukan pengaruh penggunaan atraktor cahaya berkedip pada bubu terhadap hasil tangkapan ikan karang dan mengidentifikasi jenis-jenis ikan hasil tangkapan. Penelitian ini dilakukan di perairan pantai Kampung Ambon, Kecamatan Likupang Timur, Kabupaten Minahasa Utara dengan menggunakan metode eksperimen. Data dikumpulkan dari enam unit bubu besi dengan dinding jaring, selama 6 hari. Pada 3 unit bubu dipasangkan umpan ikan Malalugis dan cahaya berkedip; dan 3 unit lainnya hanya dipasangkan umpan ikan Malalugis. Hasil tangkapan bubu selama penelitian berjumlah 71 ekor ikan, dimana 49 ekor ikan tertangkap dengan bubu lampu kedip dan 22 ekor ikan tertangkap dengan bubu tanpa cahaya berkedip. Hasil analisis uji t menunjukan pengaruh yang berbeda nyata terhadap hasil tangkapan antara bubu dengan cahaya berkedip dan bubu tanpa lampu berkedip.
