Abstract
The increasing global popularity of peaceful bettas (Betta imbellis) in the ornamental fish trade has raised concerns, particularly considering that breeding stocks are often derived from wild populations. The presence of diseases in wild fish poses a significant threat to captive populations. While extensive research has been conducted on domesticated Betta splendens, exploring their susceptibility to diseases such as piscinoodiniasis, ichthyophthiriasis, mycobacteriosis, and epizootic ulcerative syndrome, similar investigations on the susceptibility of B. imbellis is lacking. This study aimed to address this knowledge gap by assessing the frequency of disease occurrence in two wild B. imbellis populations in Klang and analysing the disparities in disease prevalence between them. Twenty B. imbellis specimens were netted at two sites and water quality tests were conducted simultaneously. The captured fish were subjected to euthanasia, necropsy, and thorough examination, including macroscopic and microscopic analyses of various organs (skin, gills, liver, kidney, and muscle tissue) to detect lesions and pathogens. The results showed that all specimens examined were completely free of the four diseases examined. Furthermore, there was no difference in disease prevalence between the two populations. In conclusion, the research showed that wild B exhibited an astonishing lack of all four diseases. imbellis, possibly caused by things like small sample sizes, fish that are already infected being eaten, natural mortality, or unfavourable environmental conditions for pathogens. But the veracity of these illnesses' rarity in wild B. Imbellis is still up in the air. This emphasizes how important it is to conduct more thorough studies with bigger sample sizes in order to gain a thorough understanding of the health condition of wild B. imbellis, and so add a great deal to the current scientific conversation in this area.
