Kualitas Benih Ikan Mas Cyprinus carpio di Kabupaten Garut Berdasarkan Kelimpahan Ektoparasit

Abstract

Ketersediaan benih yang sehat merupakan salah satu faktor keberhasilan budidaya ikan. Benih yang sehat dapat ditentukan salah satunya melalui kelimpahan ektoparasitnya. Tujuan Proyek Akhir ini adalah mengidentifikasi dan menghitung kelimpahan ektoparasit pada benih ikan mas dari lima kecamatan di Kabupaten Garut untuk menentukan kualitas benih ikan mas. Sampel ikan diambil secara acak dari lima kecamatan di Kabupaten Garut yaitu Kecamatan Banyuresmi, Bayongbong, Pangatikan, dan Karangpawitan, sebanyak 10 ekor pada setiap lokasi. Sirip, sisik, dan insang ikan sampel diperiksa untuk diidentifikasi dan dihitung kelimpahan ektoparasitnya. Nilai prevalensi di seluruh lokasi pengambilan sampel 100% menandakan parasit selalu ditemukan pada benih ikan mas yang diamati, namun nilai intesitas rata-rata 35,28 individu/ekor masuk kategori infeksi sedang. Terdapat enam jenis ektoparasit yang teridentifikasi yaitu Dactylogyrus sp., Gyrodactylus sp., Trichodina sp., Chilodonella sp., Oodinium sp., dan Ichtyopthirius multifiliis, Trichodina sp. merupakan parasit dengan nilai prevalensi, intensitas, dan dominansi tertinggi. Selain itu, semua benih yang diperiksa tidak memperlihatkan gejala klinis serta respon ikan terhadap pakan cukup baik, sehingga dapat disimpulkan bahwa kualitas benih ikan mas di Kabupaten Garut masih cukup baik.

The availability of healthy fry is one of the success factors of fish farming. Healthy seeds can be determined through the abundance of ectoparasites. The purpose of this Final Project is to identify and calculate the abundance of ectoparasites in goldfish fry from five sub-districts in Garut Regency to determine the quality of goldfish fry. Fish samples were taken randomly from five subdistricts in Garut Regency, namely Banyuresmi, Bayongbong, Pangatikan, and Karangpawitan Subdistricts, totaling 10 fish in each location. The fins, scales, and gills of the sampled fish were examined to identify and calculate the abundance of ectoparasites. The prevalence value at all sampling sites was 100%, indicating that parasites were always found in the carp fry observed, but the average intensity value of 35.28 individuals/head was categorized as moderate infection. There were six types of ectoparasites identified, namely Dactylogyrus sp., Gyrodactylus sp., Trichodina sp., Chilodonella sp., Oodinium sp., and Ichtyopthirius multifiliis, Trichodina sp. was the parasite with the highest prevalence, intensity, and dominance values. In addition, all examined fry did not show clinical symptoms and the fish response to feed was quite good, so it can be concluded that the quality of carp fry in Garut Regency is still quite good.
