Performa Pertumbuhan Benih Lobster Air Tawar Capit Merah Cherax quadricarinatus yang diberi Pakan Komersial Berbeda

Abstract

Pakan berkualitas dan biaya relatif murah menjadi salah satu upaya untuk meningkatkan performa pertumbuhan benih lobster air tawar capit merah sebagai usaha budidaya berkelanjutan. Penelitian ini bertujuan untuk menentukan pakan komersial yang dapat memberikan dampak positif terhadap kinerja pertumbuhan. Penelitian menggunakan tiga perlakuan, yaitu perlakuan A pakan komersial protein 40%, perlakuan B pakan komersial protein 41%, dan perlakuan C pakan komersial protein 41%. Benih awal lobster air tawar capit merah yang digunakan berukuran panjang rata-rata 2,1±0,1 cm ekor-1 dan bobot rata-rata 0,24±0,03 g ekor-1 . Lobster uji dipelihara pada akuarium 1×0,4×0,4 m3 dengan padat tebar 50 ekor m-2 selama 60 hari. Pemberian pakan dua kali sehari pada pukul 07.00 dan 17.00 WIB dengan feeding rate (FR) 3%. Hasil penelitian performa pertumbuhan menunjukkan bahwa setiap perlakuan tidak berbeda nyata. Parameter Feed cost per gain (FCG) menunjukkan hasil yang berbeda nyata, perlakuan B dan perlakuan C berbeda nyata terhadap perlakuan A. Pemberian pakan komersial pada benih lobster air tawar capit merah dengan kadar protein 41% menghasilkan nilai FCG Rp26.579±2.624.

Quality feed and relatively low cost are among the efforts to improve the growth performance of freshwater red claw lobster seedlings as a sustainable aquaculture practice. This research aims to determine the commercial feed that can have a positive impact on growth performance. The study used three treatments: treatment A with commercial feed containing 40% protein, treatment B with commercial feed containing 41% protein, and treatment C with commercial feed containing 41% protein. The initial freshwater red claw lobster seedlings used had an average length of 2.1±0.1 cm per individual and an average weight of 0.24±0.03 g per individual. The test lobsters were kept in a 1×0.4×0.4 m3 aquarium at a stocking density of 50 individuals per square meter for 60 days. Feeding was provided twice a day at 07:00 and 17:00 local time with a feeding rate (FR) of 3%. The research results on growth performance showed no significant differences among the treatments. The feed cost per gain (FCG) shows significant differences, with treatments B and C differing significantly from treatment A. Providing commercial feed to freshwater red claw lobster juveniles with a protein content of 41% resulted in an FCG value of Rp26,579±2,624.
