Variation in Condition Factor of Some Freshwater Fishes from Epie Creek, Bayelsa State, Nigeria

This study assessed seasonal influence in condition factor of some freshwater fishes from Epie creek, Bayelsa state, Nigeria. The fishes were caught with the help of local fishermen in the area, and condition factor was determined following standard biometric protocol. Findings showed condition factor of 0.69 (Chrysichthys furcatus) to 2.99 (Synodontis clarias) for dry season and 0.65 (Gnathonemus deboensis) to 1.35 (Citharinus citharus) for wet season. The condition factor was less than 1 for Schilbe mystus in both seasons of study, and Gnathonemus deboensis and Citharinus citharus during the dry season.Variation in the well-being of the fish differs among the species as well as season. The well-being of the fish could be influence by level of anthropogenic activities in the creek.
