Bangladesh’s rapid growth in fish farming is threatened by heavy metal contamination. Recent research found chromium levels in farmed Mrigal fish four times above FAO’s safe limit. Though current levels may not harm humans, concerns arise over heavy metals in fish feed and polluted water sources. Lack of regular pond cleaning and use of contaminated feed contribute to the issue. Experts urge government action to monitor fish feed quality and water safety to ensure the health of consumers and sustain the aquaculture industry.
