Abstract

The contribution of environmental factors to the estimations of Eustrangylides africanus larvae densities in Clarias gariepinus and C. anguillaris from Bida flood plain of Nigeria was investigated. Six environmental factors (sand, silt-clay, soil pH, water turbidity, dissolved oxygen and total phosphate content) having positive or negative correlation coefficient (r) between 0.50 and 0.85 contributed to the estimations of E. africanus larvae densities in the wild population of Clarias species.
