Perbedaan Penambahan Tepung Bekicot (Achatina fulica) pada Pakan Komersil Terhadap Hasil Pemijahan Induk Ikan Bawal (Colossoma macropomum)

Snails can be used as an addition to brood fish feed to reduce the price of feed which is relatively expensive and has a protein content of 43.15%, snails (Achatina fulica) can be used as an additive to commercial feed. The aim of the study was to determine the effect of using the addition of snail flour as an additional feed on the spawning yield of the pomfret (Colossoma macropomum) broodstock. This research uses 3 concrete tub pools. The study consisted of 3 treatments, namely: commercial feed without the addition of snail flour as a control. Treatment A added snail flour at a dose of 30%/kg feed, treatment B added snail flour at a dose of 40%/kg feed. The results showed that the addition of snail flour to commercial feed at a dose of 40%/kg feed obtained the highest fecundity value of 750,000 eggs at the egg fertilization rate of 92% with 98% hatching of eggs and 91% survival. While the lowest was in the control treatment with a fecundity level of 588,000 at the egg fertilization rate of 50% with an egg hatching rate of 80% and the survival rate of the control treatment obtained by 79%.
