Abstract

Pertambakan Gunung Anyar (PGA) merupakan salah satu wilayah budidaya di daerah Pantai Timur Surabaya yang berdekatan dengan pemukiman sehingga berpotensi tercemar akibat kegiatan antropogenik di wilayah tersebut. Pencemaran air dapat menyebabkan ikan terjangkit adanya parasit, salah satunya ektoparasit di permukaan kulit ikan. Infeksi ektoparasit dapat dikaitkan dengan perubahan kromatofor sisik ikan. Penelitian ini bertujuan mendapatkan data prevalensi dan intensitas ektoparasit pada ikan bandeng di PGA dan keterkaitannya dengan densitas kromatofor sisik. Sampling air dan ikan bandeng dilakukan pada bulan Desember dan Januari. Parameter kualitas air yang diukur meliputi suhu, pH, DO, dan salinitas. Total sampel ikan berjumlah 42 ekor berukuran ±35 cm dan diambil dari 3 lokasi PGA. Sampel ektoparasit diambil dari kulit ikan dengan metode scrapping, kemudian diidentifikasi dan dianalisis. Selanjutnya dilakukan perhitungan prevalensi dan intensitas serta penentuan status berdasar Williams & Bunkley-Wiliams. Hasil identifikasi ektoparasit ditemukan 6 jenis ektoparasit yaitu Trichodina sp., Ichtyophytirius multifisilis, Amyloodinium ocellatum, Oodium sp., Gyrodactylus sp., dan Tyrophagus longior. Hasil analisis prevalensi dan intensitas yaitu semua sampel ikan bandeng terdeteksi terinfeksi ektoparasit dengan prevalensi 100% (kategori infeksi sangat parah) dan semua sampel ikan bandeng memiliki intensitas dengan status “sedang” yaitu 13.29 ; 15.43; 19.57 ind. parasit/ekor ikan. Berdasarkan jenisnya, nilai prevalensi dan intensitas tertinggi adalah protozoa jenis Ichtyophytirius multifisilis (P = 86-93% ; I = 4.42 – 6.64 ind. parasit/ekor ikan). Hasil koefisien korelasi (r) antara intensitas ektoparasit dengan kromatofor pada ikan bandeng tergolong sangat lemah (r = 0.02 sd/ 0.05).

Gunung Anyar Aquaculture (PGA) is one of the cultivation areas on the East Coast of Surabaya which is close to residential areas so it has the potential to be polluted due to anthropogenic activities in the area. Air pollution can cause fish to contract parasites, one of which is ectoparasites on the surface of the fish's skin. Ectoparasite infections can be associated with changes in fish scale chromatophores. This study aims to obtain data on the prevalence and intensity of ectoparasites in milkfish in PGA and its relationship with scale chromatophore density. Water and milkfish samples were collected in December and January. Water quality parameters measured include temperature, pH, DO, and salinity. The total fish samples were 42 fish measuring ±35 cm and were taken from 3 PGA locations. Ectoparasite samples were taken from fish skin using the scrapping method, then identified and analyzed. Next, prevalence and intensity calculations were carried out as well as status determination based on Williams & Bunkley-Wiliams. The results of ectoparasite identification found 6 types of ectoparasites, namely Trichodina sp., Ichtyophytirius multifisilis, Amyloodinium ocellatum, Oodium sp., Gyrodactylus sp., and Tyrophagus longior. The results of the prevalence and intensity analysis were that all milkfish samples were detected to be infected with ectoparasites with a prevalence of 100% (very severe infection category) and all milkfish samples had an intensity of "medium" status, namely 13.29; 15.43; 19.57 ind. parasites/fish tails. Based on the type, the highest prevalence and intensity value is the protozoan type Ichtyophytirius multifisilis (P = 86-93%; I = 4.42 – 6.64 ind. parasites/fish), and the results of the correlation coefficient (r) between the intensity of ectoparasites and chromatophores in milkfish are classified as very weak (r = 0.02 to 0.05).
