 family) of the same genus as the papyrus plant. The tigernut has been cultivated since early times (chiefly in S Europe and W Africa) for its small, tuberous rhizomes, which are eaten raw or roasted, used for hog feed, and pressed for the juice to make a beverage. A nondrying oil (usually called chufa) is also obtained from the rhizome. In W Africa the plant often grows in great concentration and is gathered from the wild. In the S United States it is sometimes a troublesome weed in planted fields. Other names are earth almond and yellow nut grass. The tigernut is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

This result is not in agreement with earlier report (4) that recorded a decline in growth of African catfish juveniles fed tigernut based diets beyond 50% dietary level.
It may also mean that the fish were able to tolerate the tigernut at older age with better physiological adaptation compared to the juvenile stage when the earlier study was conducted.
