The occurrence of Ichthyophthirius multifiliis infection on invasive freshwater fish, the Peacock Bass (Cichla spp.) from Tasik Telabak, Malaysia.

Journal of Agrobiotechnology (Malaysia), 14. pp. 1-6. ISSN 2180-1983

Peacock bass (Cichlaspp.) is an invasive fish that has established feral population in many freshwater water bodies in Malaysia. Among the negative impact of invasive species are the co-introduction of new parasites, and they also may act as vector to various disease causal agents. The aim of this study was to identify and to measure the prevalence of parasites of Peacock bass from Tasik Telabak, Terengganu, Malaysia. A total of 28 fishes were sampled by line fishing with the help of anglers and examined for parasites by using general parasitological method and microscopic technique. 3 groups of parasites (Protozoa, Digenea and Nematoda) were found infecting Peacock Bass from the lake. 46% of the samples were infected by Ichthyophthirius multifiliis, a common protozoan parasite that known as the causal agent for White Spot Disease (WSD) in fishes. Since I. multifiliis is not a common parasite for wild Peacock Bass in their native area, this finding could indicate the potential of parasite spillback phenomena from the freshwater fish cages from aquaculture activities in the same lake.

Abstract

Peacock bass (Cichlaspp.) is an invasive fish that has established feral population in many freshwater water bodies in Malaysia. Among the negative impact of invasive species are the co-introduction of new parasites, and they also may act as vector to various disease causal agents. The aim of this study was to identify and to measure the prevalence of parasites of Peacock bass from Tasik Telabak, Terengganu, Malaysia. A total of 28 fishes were sampled by line fishing with the help of anglers and examined for parasites by using general parasitological method and microscopic technique. 3 groups of parasites (Protozoa, Digenea and Nematoda) were found infecting Peacock Bass from the lake. 46% of the samples were infected by Ichthyophthirius multifiliis, a common protozoan parasite that known as the causal agent for White Spot Disease (WSD) in fishes. Since I. multifiliis is not a common parasite for wild Peacock Bass in their native area, this finding could indicate the potential of parasite spillback phenomena from the freshwater fish cages from aquaculture activities in the same lake.
