ABSTRAK

Pengendalian polikaeta pengebor dengan menggunakan berbagai konsentrasi larutan garam telah dilakukan pada tiram mutiara (Pinctada maxima). Berdasarkan jumlah polikaeta yang keluar, hasil percobaan ini menunjukkan bahwa perendaman dengan konsentrasi garam 0 ppt. 45 ppt, dan 60 ppt selama 15 menit lebih efektif dibandingkan pada konsentrasi 15 dan 30 ppt. Tingkat kelangsungan hidup tiram mutiara yang diamati 7 hari setelah perendaman dalam larutan garam mencapai 100%.
