Seasonal Variation in Condition Factor of Some Important Fish Species from Ikoli Creek, Niger Delta

This study investigated seasonal variation in condition factor of five important fish species Ikoli creek, Niger Delta Nigeria. The fish samples were obtained from the creek with the assistance of local fishermen. The condition factor was determined using standard biometric method. Results showed that condition factor ranged from 0.81 – 2.09 and 0.81 – 1.87 for wet and dry season respectively. Synodontis clarias and Schilbe mystus has condition factor greater than 1 and Gnathonemus deboensis and Citharinus citharus had condition factor less than 1. This suggests that seasons affect well-being of a fish. Also, well-being of a fish differs between different species. Lower condition factors observed for Gnathonemus deboensis and Citharinus citharus also suggest that anthropogenic activities in the creek is having impact on fish-well-being.
