The Culture of Tilapia Nigra (Gunther) in Ponds III-The Early Growth of Males and Females at Comparable Stocking Rates, and the Length/Weight Relationship. East African Agricultural and Forestry Journal, Vol. 25, 169-173. https://doi.org/10.1080/03670074.1960.116652580012-8325https://kalroerepository.kalro.org/handle/0/2846At equivalent stocking rates under comparable pond conditions, isolated male Tilapia nigra show a faster growth rate than isolated females. This sexual dimorphism in growth is probably genetically controlled, and is also characteristic of the closely related species T. mossambica and others of this group. This superiority in male growth is the basis of the monosex culture technique, and probably occurs under all conditions. Length for length, isolated males also show a greater weight per fish than do mixed breeding fish.enhttp://creativecommons.org/licenses/by/3.0/Journal ContributionPondsStocking rateHatchingBreedinghttps://doi.org/10.1080/03670074.1960.11665258
