The premnt world production of tilapias is relatively low, despite their high potential for aquaculture. Most re-& efforts towds their husbandry have been aimed at solving the major problem in tilupia culture, uncontrolled reproduction. Other attributes of potential importance, such as temperature and salinity tolelance, feeding habits and growth capacity have been largely neglected. Real attempt^ at genetic improvement in tilapias have been restricted to the production of all-male hybrid progeny. A rational choke of species or isolates, according to economically important traits, instead of locally available species could be a ftst step m incraaslng production by genetic metha
