Reproductive Tract Morphometry and Evaluation of Fresh Wild African ‎Catfish (Clarias gariepinus) Milt from Lake Alau, Maiduguri, Nigeria‎

Reproductive morphometry of Clarias gariepinus (C. gariepinus) is essential in distinguishing different species that are closely related to it and adequate information required regarding the seasonal variation milt characteristic wild species. This study was designed document reproductive tract morphometric dimensions characteristics C. during spawning non-spawning seasons Lake Alau, Maiduguri, Nigeria. Sixty male brood stocks were used comprising thirty each for seasons. The tracts removed their measured. samples collected, pooled evaluated. Results showed body weight, sperm concentration testicular indices differed significantly (p˂0.05) between two evaluation. In addition, a positive correlation (p˂ 0.05) weight fish volume (r = 0.656 r 0.646) also observed both It concluded left testis heavier, longer thicker than right. Nonetheless, had larger weights higher spermatozoa season season; those with lower weights.
