The Effect of Noni Fruit (Morinda citrofolia) on Controlling Argulus sp. in Common Carp (Cyprinus carpio)

Abstract

Argulus sp. is one of the ectoparasites that commonly infects common carp (Cyprinus common carpio) and can reduce fish health and productivity. One environmentally friendly control method is the use of natural ingredients such as noni fruit (Morinda citrofolia) which contains bioactive compounds that have antiparasitic properties. This study aimed to analyze the effect of noni fruit extract on the control of Argulus sp. in common carp and to determine the effective dosage for controlling the parasite. The study used an experimental method with a Completely Randomized Design (CRD) consisting of four treatments of noni fruit extract concentration: P1 (1%), P2 (2%), P3 (3%), and P4 (4%) with five replications. The observed parameters included fish survival rate, Argulus sp. mortality time, parasite mortality, prevalence, and intensity of parasite infestation. The result showed that the administration of noni fruit extract had a significant effect on mortality, prevalence and intensity of Argulus sp. infestation. The best treatment was obtained at a concentration of 2% (P2), with a fish survival rate of 100%, Argulus sp. mortality of 98,67%, prevalence of 4 %, and infestation intensity of 0.2 parasites each fish.
