Pemberian Kombinasi Pakan Buatan dan Cacing Sutera terhadap Pertumbuhan dan Kelangsungan Hidup pada Benih Ikan Lele Clarias sp. Umur 4 Hari

Abstract

Catfish hatchery activities still require natural feed which is silk worms. The availability of silk worms in nature are limited to its season. This research is purpose for know influence the feeding combinations artificial feed and silk worms with the different percentage towadrs growth and survival of catfish seed. Seed in the form of larvae of catfish was 4 days with a density of 10 fish/l in a container measuring 20x20x20 cm aquarium. Feed that is given (30-50%) of its average weight each day for 20 days of maintenance. The treatment are silk worms 100% (PA), artificial feed 100% (PB), artificial feed 75% and silk worms 25% (PB75+PA25), artificial feed 50% and silk worms 50% (PB50+PA50), artificial feed 25% and silk worms 75% (PB25+PA75). The results showed that seed catfish fed PB50 + PA50 have the growth of catfish good seed is weights 25+0,01mg, the absolute length of 2,04+0,04cm, the average length of 2,79+0,04cm, coefficient of variability average length 19.95+1,95%, and survival rate 85.55+0,96%.
