Abstract
Five different levels (0, 25, 50, 75, and 100 g kg−1) of algal (Ulva fasciata) meal were added to red tilapia feeds to examine its effect on growth and carcass biochemical content. Addition of ulva meal significantly improved growth performance, feed utilization, total crude protein content, and percentage of highly unsaturated fatty acids. Fish fed 75 g kg−1 or 100 g kg−1 of U. fasciata performed better than others.
