The American Soybean Association (ASA), in cooperation with the China National Fisheries Extension Center (NEC) and the Guangxi Provincial Fisheries Extension Station, conducted cage feeding trials with red drum (Sciaenops ocellata), Japanese sea bass (Lateolabrax japonicus), and blackfin sea bream (Acanthopagrus sp.) at Longmen Town, Qingzhou City, Beihai in 2000. The objective of the trials was to demonstrate that sub-market size fish of each of the three test species could be weaned from a fresh fish diet to a soymeal-based, extruded feed and economically grown to market size on the extruded feed.
