Popis: Growth performance and characterization of three strains of Oreochromis niloticus present in Côte d'lvoire were compared through a study of enzyme polymorphism: the "Bouake" strain at the Institut des Savanes (IDESSA) research station in Bouake; the same strain kept in confinement for the past six years by a small-scale fish farmer in Western Côte d'lvoire (Daloa); and a strain (named "Burkina Faso") from the Volta basin recently introduced at the IDESSA station in Bouake. The results of tests run for a duration of four months indicated that the growth performance of the three strains met the requirements of commercial aquaculturists (mean individual growth =2.5 g.day-1). All three strains were identified and differentiated using electrophoretic techniques- Results showed high levels of polymorphism, particularly in the "Bouake" strain kept at IDESSA. The authors conclude that all three strains show good potential for aquaculture. The strains present at the IDESSA station ("Bouake" and "Burkina Faso") are also polymorphic stocks that can be used in genetic improvement programs.
