The American Soybean Association (ASA), in cooperation with the China National Fisheries Extension Center (NEC) and its affiliate provincial agencies, has conducted a series of feeding trials with tilapia in ponds and cages over the past five years. These trials have been conducted on commercial fish farms throughout China, and have tested a variety of feeds and feed formula variations to determine the technical and economic feasibility of culturing tilapia in feed-based pond (80:20 technology) and cage (LVHD technology) production systems with soybean-based aquafeeds. These efforts were continued in 1997 with a feeding trial in Guangzhou that evaluated hybrid tilapia growth performance from fry to market size on soybean-based fingerling and grow-out diets.
