The use of aquatic plants as feed for Tilapia nilotica in floating cages
MetadataShow full item record
Three kinds of aquatic plants, namely, Hydrilla verticillata, Lemna minor , and Chara sp. were used as feed for the T. nilotica reared in floating cages at three levels of stocking densities: 5, 15, and 45 fishes per cage. Results of the study showed that Lemna minor gave the best effect on growth rate of the fish in every level of stocking density. Feed conversion rate ranged from 19 to 33; Lemna minor was the lowest (33:1), while Chara sp. was the highest (19:1).
