Abstract

Fish distresses are commonly reported from the fish cultured activity. Fish distress is occurred when fish cannot adapt to stress or suffering to their surrounding environment. This problem caused by several reason i.e. fish disease which include parasitology, bacteriology, virology and environmental stress. In the natural environment, most of the cases are rise from the human exploitation i.e: coastal development, sand mining, mangrove logging etc. Most of the fish distresses have a relatively caused by low tolerance of variations in environmental conditions and their death is often a potent indicator of problems in their environment. In this study, total of 30 fishes from three sampling sites along the Tebrau Straits (1°27'09.3"N 103°46'00.3"E) were collected for this study. Eight type of fish species were weighed and measured respectively. The objective of this study are to determine the prevalence and mean intensity of the parasites. Prevalence of four phylum of parasites with six genus have been analyses which categorized in two group such as ectoparasites; i) protozoan (7%), ii) plathyhelminthes (10%), iii) parasitic crustacean, i.e; Ergasilus sp. (0.1%); Caligus sp. (0.5%); Pseudolernanthropus sp. (0.2%); Hatschekia sp. (0.2%) and one type of endoparasite which is nematode (0.7%). The parasites found during this study were recorded and the data were summarized in the results.
