Microalgae (Selenastrum Capricornutum) Growth Inhibition Following Exposure to Pond Water: Monitoring Pond Toxicity

Abstract Bio-indicators are organisms, such as bacteria, that can be used to determine the state of health and biogeographic change in the environment. Microalgae, for example, are used as bioindicators to assess the health of natural ecosystems such as pond water. They're utilized to evaluate the media in which a biological system operates, as well as the molecules within it. They serve as a symbol of the high quality of its surroundings. Microalgae respond quickly to changes in the environment, making them an excellent biomarker for evaluating the quality of pond and water pollutants. Fish are grown in a fixed pool of water known as a pond, with old water being replaced every five days or more. For the duration of the investigation, hazardous metabolites in the pond water were examined for the beginning or build-up of harmful metabolites. The Algaltoxkit approach was used for five days. Selanastrum capricornutum, a microalgae, was grown as a bio-indicator of pond toxicity. The pond water was collected without dilution from day one to day five. The microalgae test was conducted for 72 hours, with minor deviations from ISO guideline 8692. Microalgae growth inhibition varied among the days monitored, according to the results, findings imply that pond water poisoning begins on day 2-5. This finding shows that hazardous compounds in the pond water at day 5 may be affecting the fish's ability to grow and develop normally. The Algaltoxkit kit could also be a useful, quick test instrument for detecting the beginning of hazardous metabolites in a fish pond.
