Kinerja Pertumbuhan ikan lele (Clarias sp.) yang diberi pakan komersial apung dan tenggelam di waduk Cirata, Jawa Barat

Abstract

Penelitian ini bertujuan membandingkan tiga produk pakan komersial berbeda terhadap kinerja pertumbuhan ikan lele (Clarias sp.) yang dipelihara di keramba jaring apung (KJA) Waduk Cirata, Jawa Barat. Penelitian ini menggunakan tiga produk pakan komersial berbeda yaitu pakan apung komersial A dengan kadar protein (32,43%), pakan apung komersial B dengan kadar protein (34%) dan pakan tenggelam komersial C dengan kadar protein (32,47%). Ikan dipelihara di petakan KJA yang berukuran 1,5 × 1,5 × 3 m dengan bobot rata-rata pada awal tebar 6,73 g. Pemberian pakan dilakukan dengan frekuensi dua kali sehari pada pukul 08.00- 09.00 dan 16.00-17.00 dengan metode at satiation selama 60 hari masa pemeliharaan. Hasil penelitian menunjukkan bahwa perlakuan pakan apung B (34%) memberikan performa terbaik pada biomassa akhir, laju pertumbuhan spesifik, konversi pakan dan feed cost per gain terbaik dibanding dua pakan komersial lainnya. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa kinerja pertumbuhan ikan lele tertinggi pada pemeliharaan sistem KJA didapatkan pada pakan komersial perlakuan B dengan kadar protein 34%.

This study aims to compare three different commercial feed products on the growth performance of catfish (Clarias sp.) reared in floating net cages (KJA) of Cirata Reservoir, West Java. This study used three different commercial feed products, namely commercial floating feed A with a protein content of 32.43%, commercial floating feed B with a protein content of 34%, and commercial sinking feed C with a protein content of 32.47%. Fish were reared in KJA plots measuring 1.5 × 1.5 × 3 m with an average weight at the beginning of stocking of 6.73 g. Feeding was carried out twice a day at 08.00-09.00 and 16.00-17.00 with the at satiation method for 60 days of rearing. The results showed that floating feed treatment B (34%) provided the best performance in final biomass, specific growth rate, feed conversion, and feed cost per gain compared to the other two commercial feeds. Based on the results of this study, it can be concluded that the highest growth performance of catfish in the KJA system was obtained from commercial feed treatment B with a protein content of 34%.
