The American Soybean Association (ASA), in cooperation with the China National Fisheries Extension Center (NEC), the Guangdong Provincial Fisheries Extension Center, and the Long Gang Fisheries Research Institute coastal cage culture farm in Dong Shan Bay, conducted feeding trials with green grouper (Epinephelus awoara), red drum (Sciaenops ocellata) and pompano (Trachinotus ovatus) in 2000. The objective of the green grouper and pompano trials was to compare growth and economic performance of these species from fingerling to market size with a traditional fresh fish diet and a soymeal-based, extruded aquafeed. The objective of the red drum trial was to demonstrate that sub-market size red drum could be weaned from fresh fish to a soymeal-based manufactured feed and economically grown to market size on the manufactured feed.
