Abstract
Penelitian ini bertujuan untuk mengetahui prevalensi dan derajat infeksi Anisakis sp. yang ditemukan pada saluran pencernaan ikan kakap merah (Lutjanus malabaricus) di tempat pelelangan ikan Brondong Lamongan berdasarkan panjang total ikan. Spesimen ikan dibedah dengan cara dibuat sayatan pada bagian ventral ikan. Organ usus dan lambung diletakkan ke dalam cawan petri yang berisi larutan fisiologis NaCl 0,9% dan diidentifikasi dengan menggunakan mikroskop cahaya. Hasil pengamatan menunjukkan bahwa ikan kakap merah telah terinfeksi larva 3 (L3) Anisakis sp.. Prevalensi dan derajat infeksi ikan kakap merah berukuran 25-37 cm lebih besar dibandingkan dengan ikan kakap merah yang berukuran 21-24 cm. Nilai prevalensi ikan berukuran 21-24 cm sebesar 66,67 % dengan nilai derajat infeksi sebesar 5,2 parasit/ikan sedangkan pada ikan berukuran 25-37 cm nilai prevalensinya sebesar 80 %. Dengan nilai derajat infeksi sebesar 18,25 parasit/ikan. Berdasarkan hasil uji statistik menggunakan Uji T menunjukkan bahwa, jumlah Anisakis sp. pada saluran pencernaan ikan kakap merah berhubungan nyata dengan panjang tubuhnya (P<0,05).
