| description | The study evaluates the hybridizations between two African catfish, <i>C. gariepinus</i> and <i>C. macromystax,</i> using artificial reproduction. Fecundity and gonadosomatic index were assessed, and growth performance at different developmental stages was evaluated. The results indicated that both species possess a similar gonadosomatic index. The parent <i>C. gariepinus</i> possesses significantly (<i>p</i> < 0.05) higher male reproductive quality than <i>C. macromystax</i>. Fecundity was significantly higher (<i>p</i> < 0.05) in the female parent of <i>C. macromystax</i> and lower in <i>C. gariepinus</i>. The highest fertilization rates and hatching rates were achieved in the hybrid cross of ♀<i>C. macromystax</i> × ♂<i>C. gariepinus</i> (♀<i>Cm</i> × ♂<i>Cg</i>) which also recorded the lowest deformed larva rate. Survival rates at the larval stage were more than 80%, with the highest record of survival in the hybrid ♀<i>Cm</i> × ♂<i>Cg</i>. However, survival rates in the fry stage were lower than 70%. The hybrid cross (<i>C. macromystax</i> × <i>C. gariepinus</i>) outperformed the parental cross of <i>C. macromystax</i> but was not significantly similar to the parental cross of <i>C. gariepinus</i>. The study revealed the potential of the hybrid ♀<i>C. macromystax</i> × ♂<i>C. gariepinus</i>, and hybridizations of ♀<i>C. macromystax</i> × ♂<i>C. gariepinus</i> (♀<i>Cm</i> × ♂<i>Cg</i>) are indeed possible and proved to have a better growth and survival rate under semi-arid conditions, which would contribute significantly to the improvement of <i>C. macromystax</i> production in captivity. |
