Based on results of the pilot study, the following recommendations are made when the choice of gear is limited because of manpower or equipment constraints, seines, electroshocking, gill nets, and hoop nets should be used in riverine systems the number of habitats studied should be limited to dike fields, revetted banks, natural banks, and abandoned channels the same habitat type should be sampled at two or more different locations to determine variance and comparability of physical and biological parameters the number of samples taken with a particular gear in any given habitat should be increased to reduce the variation in Cf values because of considerable temporal variation in species composition and abundance of fish communities in the different habitats, sampling should be conducted throughout the year and before beginning a major field study, a pilot study should be conducted to familiarize field personnel with the physical characteristics of a study area, the fish species associated with the different habitats, and adequate sampling methods for the different fish communities.
