Pengaruh Pemberian Tepung Buah Mengkudu (Morinda citrifolia) pada Pakan Komersil dengan Feeding Rate yang Berbeda terhadap Pertumbuhan dan Kelangsungan Hidup Ikan Lele Dumbo (Clarias gariepinus)

Abstract

Catfish is a freshwater fishery commodity that is quite popular and popular among the public. The advantage of this fish is its fast growth. However, complete nutritional needs and the amount of daily feed are factors in meeting growth and survival. Noni fruit is a natural alternative that is quite effective in increasing the growth and survival of fish. The aim of this research was to determine the effect of providing noni fruit flour (Morinda citrifolia) in commercial feed with different feeding rates on the growth and survival of African catfish (Clarias gariepinus). This research was carried out from December to January 2023. The experimental design used was a Randomized Block Design (RAK) with 2 factors and 3 replications. The first factor is the provision of noni fruit flour and commercial feed with treatment doses namely M1 (15 gr/kg feed), M2 (20 gr/kg feed) and M3 (25 gr/kg feed) and the second factor is different feeding rates F1 (3 %), F2 (4%) and F3 (5%). This research was carried out during 60 days of maintenance to determine weight growth, length growth, Feed Convertion Ratio (FCR), survival rate and water quality. The results of the research showed that giving noni fruit flour to commercial feed with different feeding rates showed a very significant effect P(<0.01) on weight growth and length growth with the best treatment in the M3F2 treatment (giving 25 gr/kg noni fruit flour). feed with feeding rate 4%) and a very significant effect P(<0.01) on the Feed Convertion Ratio (FCR) with the best treatment in the M3F1 treatment (giving noni fruit flour 25 gr/kg feed with a feeding rate of 3%) and survival rate which is very good.
