Prevalensi dan Intensitas Endoparasit pada Ikan Gabus (Channa striata) dari Budidaya dan Alam

Abstract

Penelitian bertujuan untuk membandingkan prevalensi dan intensitas endoparasit pada usus ikan Gabus (Channa striata) budidaya air tawar dan tangkapan alam. Usus didapatkan dari 20 ekor Ikan Gabus budidaya air tawar dan 20 ekor dari alam (panjang total 25±3 cm) yang diambil dan diawetkan dengan buffer formalin 0,5%, kemudian diamati menggunakan mikroskop stereo dan compound yang terhubung dengan kamera fotomikroskop OptiLab. Identifikasi endoparasit mengacu pada studi referensi. Prevalensi (prev.), dan intensitas (I) endoparasit dihitung berdasarkan jumlah endoparasit yang ditemukan di dalam usus ikan. Hasil menunjukkan bahwa jumlah endoparasit, prevalensi, dan intensitas pada ikan Gabus dari alam memiliki nilai yang lebih tinggi, yaitu Pallisentis sp. (prev=65%; I= 34.3 ind. per ikan dan Camallanus sp. (prev=35%; I=6.1 ind. per ikan) dibandingkan dengan ikan Gabus budidaya air tawar yang terinfeksi Pallisentis sp. saja (prev=30%; I=10. ind. per ikan).
