Philippine researchers eye agricultural waste as fish feed alternative

摘要

Researchers in the Philippines are providing fish farmers new options to pull down feed costs without comprising fish performance. At the College of Fisheries and Ocean Sciences of the University of the Philippines - Visayas, Ritche Declarador and herteam enhanced the feed value of copra meal to make it suitable as partial replacement for soybean in the diet of white leg shrimp (Litope-naeus vannamei) and milkfish (Chanos chanos).Considering that the Philippines is the world's biggest producer of coconut oil, there is an abundance of copra meal. It has, however, a low feed value due to its low protein content, high fiber, gritty appearance and low texture.
