Growth in Experimental Populations of Tilapia mossambica.

The article provides information on the growth in experimental populations of Tilapia mossambica. It is stated that each fish population was measured from 17.5 to 33.5 months. The sex-differential growth is well recognized in the genus Tilapia and has even been used as the basis of a method of mechanically separating the sexes. In addition, the length frequencies for populations and combined populations were bimodal reflecting the sexual growth difference. The progress of the length modes represents a combination of effects of recruitment, growth and mortality.
