Activated Carbon Made from Rice Husks and Coconut Shell as Feed Supplement for Reducing Uptake of Metal/Loids, PAHs and PCBs by Nile Tilapia

The proposed study aims to use activated charcoal-based fish feed (AC-FF) made from bioresources (rice husks and coconut shells) for culturing Nile tilapia (Oreochromis niloticus). Laboratory-scale and field-scale fish feeding experiments will be conducted to assess the effect of AC-FF on fish growth, histology of digestive tract, immunity, gill and gut microbiota diversity. The bioaccessibility of pollutants in fish feed will be studied using an in vitro gastrointestinal digestion model. The potential health risk of consuming the fish products produced from the AC-FF diet will also be evaluated based on the human health risk assessment model
