Description:

The major purpose of the project is using food waste as a resources to replace part of fish meal in commerical feed for cultureing freshwater fish (Nile Tilapia (Oreochromis Niloticus) and Jade Perch (Scortum Barcoo)). It is hope that fish fed by food waste pellets contain a lower pollutatnts levels than those fish fed by commerical fed. The major objecctives of this study are as the following: (1) to upgrade food wastes as feeds for culturing freshwater fish (Nile tilapia and Jade perch) and determine contaminants (persistent toxic substances (dichlorodiphenyltrichloroethane (DDT), polycyclic aromatic hydrocarbons (PAHs) and heavy metals (lead (Pb) and mercury (Hg)) ) concentations in food waste feeds compared with commercial feed; (2) to conduct feeding trials of fish using upgrade food wastes as feeds VS commercial feed; and (3) to conduct human health risk assessment for consuming the fish products fed with the food waste based diets compared with those fish fed by commercial feed and purchased from local markets based on the concentrations of DDT, PAHs, Pb and Hg.
