Abstract

A study related to identification of parasites that infected farmed tilapia by using morphological characteristics was conducted from October 2022 to December 2022 in Miri and Bintulu, Sarawak, Malaysia. Thus, present study aims to determine the genera and prevalence of ectoparasites and endoparasites in selected farmed tilapia in Bintulu and Miri, Sarawak, Malaysia and to identify the risk factors which are water quality, fish length and weight associated with parasitic diseases of farmed tilapia located in Bintulu and Miri, Sarawak, Malaysia. A total of sixteen fish samples from two farms, where seven fish samples from Farm A and nine fish samples from Farm B. The parasites identification was carried out by examining the external and internal of the fish samples and identified the parasites using microscope (Leica CME Binocular Microscope). Biometric consideration included the distribution of water quality, weight, length and fish condition factors. Eleven over sixteen fish samples were found positive with parasites infection, and the parasites found were Trichodina spp., Tetrahymena spp., Piscinoodinium sp., Chilodonella sp., Eimeria sp., Ichthyophonus sp., Dactylogyrus spp., Diplostomum spp. and Microsporidia. Eimeria sp. was the most prevalence (28.57%; 95% CI: 13.81 – 49.96) recovered from the positive fish samples. Water quality in Farm B has higher prevalence of parasite infestation 77.78% (95% CI: 45.26 - 93.68) compared to water quality in Farm A counterparts 57.14% (95% CI: 25.05 – 84.18). It was found that higher prevalence of parasitic infection was among fish samples having weight >500g (100%; 95% CI: 43.65 - 96.99). Higher proportion of parasite infestation was found in fish samples with length of >30cm (100%; CI: 43.85 - 100.00). Higher parasite burden was seen on poor condition factor 100% (95% CI: 20.65 – 100.00). It will be very important to do research on the prevalence of parasites in aquaculture if one wishes to determine the extent of the economic damage that has been caused to fish farmers as a result of the impact of parasitic diseases.
