Abstract: The status and well-being of Chrysichthys nigrodigitatus silver catfish species was investigated in Asejire Reservoir and Lagos Lagoon. Growth pattern relationship and condition factor were investigated. Result obtained revealed length of C. nigrodigitatus from both water bodies had no significant difference, but weight of the samples from Lagos lagoon were significantly higher than weight of samples from Asejire reservoir. Allometric value and condition factor of fish samples recorded significant differences between sexes. Negative allometric value was determined in female samples from the two water bodies, but positive allometric value was obtained in male from Lagos lagoon. Condition factors of male samples from the two water bodies recorded significant differences; while female from Asejire reservoir had higher K-factor than female in Lagos Lagoon. Analytical and descriptive statistics were used to analyse data collected. Regression analysis was used to determine sequence of length and weight of fish; further test was done using Duncan Multiple Range Test (DMRT) to determine level of significance among fish samples. The growth indices reveal C. nigrodigitatus from both environments is in good well-being status, indicating that the environments favours C. nigrodigitatus.
