Abstract
The aim of this study was to compare some semen physical characteristics of both wild and cultured Clarias gariepinus broodstocks in order to know their relative economic advantages to farmers. Nine male broodstocks were selected with their weight ranges between 700g to1250g, with total length ranges between 51.50cm to 61.00cm. The fish were sacrificed by spinal transaction, after which the fish were dissected and the gonads were removed. The gonads were examined after weighing, and were evaluated for pH, motility, volume and sperm concentration. Descriptive statistics was used to find their minimum and maximum values. Student t-test was used to analysed the differences of their means. Also, the relationships between semen parameters were tested using the bivariate correlation coefficients of pearson. Significant differences (P
