Pengaruh Pemberian Tepung Daun Mangrove (Rhizopora apiculata) pada Pakan Komersil serta Feeding Rate yang Berbeda Terhadap Pertumbuhan Ikan Patin (Pangasius sp.)

Abstract

Catfish is a type of freshwater consumption fish, has a long silver-white body with a bluish back. Catfish is known as a commodity with bright prospects, because it has a high selling price. This is what causes the catfish (Pangasius sp.) to receive attention and interest from entrepreneurs to cultivate it. This fish is quite responsive to supplementary feeding. Mangrove flour is a raw material that is quite effective in reducing feed production costs. The purpose of this study was to determine the effect of adding mangrove flour to commercial feed with different feeding rates on the growth of catfish. This research was conducted in July - September 2022. The method used in this study was a factorial randomized block design (RAK) method with three factors, namely the first factor was the addition of mangrove leaf meal, fish meal and commercial feed with different doses M1 (95% feed commercial, 3% mangrove leaf meal and 2% fish meal), M2 (90% gram of commercial feed, 5.5% mangrove leaf meal and 2.5% fish meal). M3 (80% commercial feed, 8% mangrove leaf meal and 7% fish meal). With the second factor Feeding rate 3 (three) levels respectively 3%, 4% and 5% with 3 (three) repetitions. This research was conducted for 60 days of rearing to determine weight gain, length growth, Feed Conversion Ratio (FCR), survival rate, and water quality. The results showed that the addition of mangrove flour to commercial feed with different feeding rates showed a highly significant (p≤0.01) effect on weight gain and length gain with the best treatment on M3F3 (85% Commercial Feed + 8% Mangrove Flour FeedingRate 5% and significantly different effect (P≤0.05) on Feed Conversion Ratio (FCR) with the best treatment on M1F1 (95% Commercial Feed + 3% Fish Meal with a Feeding Rate of 3%) and at a good survival rate.
