Pengaruh Pemberian Tepung Cacing Tanah (Lumbricus rubellus) pada Pakan Komersil serta Feeding Rate yang Berbeda terhadap Pertumbuhan Ikan Lele (Clarias sp.)

Abstract

Catfish is a cultivated commodity that has various advantages, including fast growth and good adaptability to the environment. The aim of this research was to determine the effect of adding earthworm meal to commercial feed with different feeding rates on the growth of catfish. This research was carried out in May - June 2024. This research method used a factorial randomized block design (RAK) method with three factors, namely the first factor was the addition of earthworm flour, rice bran flour, and commercial feed with different doses of C1 (95% commercial feed , 3% earthworm meal and 2% rice bran meal, C2 (90% commercial feed, 6% earthworm meal and 4% rice bran meal and C3 (85% commercial feed, 8% earthworm meal and 7% rice bran meal ). The second factor is the feeding rate with three levels, namely 3%, 4%, and 5% with 3 (three) repetitions. This research was carried out for 42 days of maintenance to determine weight gain, length growth, Feed Conversion Ratio (FCR), survival rate (SR), and water quality. The results showed that the addition of earthworm meal to commercial feed with different feeding rates showed significantly different values (P≤0.01). Commercial feed with different feeding rates showed very significantly different values (P≤0.01). The treatment of adding earthworm flour with different feeding rates on the feed conversion ratio showed no significant effect (P>0.5). and the survival rate is relatively good.
