Efektivitas Suplementasi Astaxanthin Komersial pada Pakan terhadap Kinerja Pertumbuhan Ikan Mas Cyprinus carpio

Abstract

Ikan mas termasuk salah satu ikan dengan laju pertumbuhan yang cukup tinggi. Astaxanthin adalah antioksidan dari golongan karotenoid yang dapat mempengaruhi pertumbuhan ikan. Penelitian ini bertujuan mengevaluasi efektivitas suplementasi astaxanthin komersial pada pakan terhadap kinerja pertumbuhan ikan mas (Cyprinus carpio). Penelitian menggunakan empat perlakuan dan tiga ulangan, yaitu K (0 mg kg-1 pakan), L50 (50 mg kg-1 pakan), L100 (100 mg kg-1 pakan), dan L150 (150 mg kg-1 pakan). Ikan dipelihara dengan kepadatan 12 ekor per akuarium selama 60 hari. Pemberian pakan uji dilakukan secara at satiation dengan frekuensi sebanyak tiga kali sehari, yaitu pukul 08.00, 12.00, dan 16.00. Parameter yang diamati yaitu laju pertumbuhan spesifik, tingkat kelangsungan hidup, rasio konversi pakan, jumlah konsumsi pakan, retensi protein, retensi lemak, rasio efisiensi protein, dan feed cost per gain. Suplementasi astaxanthin komersial pada pakan menunjukkan kinerja pertumbuhan yang berbeda nyata (p<0,05) antar perlakuan. Kinerja pertumbuhan ikan mas (Cyprinus carpio) terbaik diperoleh pada pakan dengan penambahan astaxanthin komersial sebanyak 100 mg kg-1 pakan.

Common carp is one of the fish with a fairly high growth rate. Astaxanthin is a carotenoid antioxidant which can affect fish growth. This study aims to evaluate the effectiveness of commercial astaxanthin supplementation in feed on the growth performance of common carp (Cyprinus carpio). The research used four treatments and three replications, namely K (0 mg kg-1 feed), L50 (50 mg kg-1 feed), L100 (100 mg kg-1 feed), and L150 (150 mg kg-1 feed). Fish were maintained at a density of 12 fish per aquarium for 60 days. The test feed was given at satiation with a frequency of three times a day, namely at 08.00, 12.00 and 16.00. The parameters observed were specific growth rate, survival rate, feed conversion ratio, amount of feed consumption, protein retention, fat retention, protein efficiency ratio, and feed cost per gain. Astaxanthin commercial supplementation in feed showed significantly different growth performance (p<0.05) between treatments. The best growth performance of common carp (Cyprinus carpio) was obtained with feed supplemented with 100 mg kg-1 of commercial astaxanthin.
