A tilapia feeding demonstration was jointly conducted in 2010 by the American Soybean Association International Marketing (ASA-IM) and the Hainan Fish Breeding Farm of the Beijing Municipal Fishery Extension Center, Haikou City, Hainan Province. The objective of the demonstration was to demonstrate the optimal feed protein level for maximizing economic return for tilapia cultured in low volume, high density (LVHD) cages. The demonstration compared tilapia growth and production cost with feeds varying in protein level from 24% to 36%. Optimizing feed protein level is critical to maximizing economic return in tilapia operations, where the current economic environment and increasing competition have narrowed profit opportunities.
