THE EFFECT OF BATCH STRIPPING EGGS ON THE REPRODUCTIVE PERFORMANCE OF CLARIAS GARIEPINUS
Abstract
ABSTRACT
This study was conducted at the hatchery complex of Fisheries Department of Akwa Ibom State University, Obio Akpa Campus. This study was to investigate the effect of different batches of stripped eggs on the reproductive performances of C. gariepinus including fertilization rate, hatchability and larval survival rate. Two (2) broodstock (1 male and 1 female) were selected for breeding following standard method. The female broodstock was induced for artificial breeding with 0.5 ml of Ovaprim. Milt was collected from the male broodstock for fertilization of the eggs collected in four different stages labelled A, B, C, and D each all weighing 50g from the females induced with Ovaprim and replicated three (3) times. Results obtained in this study showed that mean fertilization rate increased significantly (p
