Environmental Impact Research Program. Community Habitat Suitability Models for Warmwater Fishes.

Abstract

Most published habitat suitability index (HSI) models for warmwater fishes have too many variables, many of which time-consuming and difficult to measure. In addition, suitability index scores are calculated using nonuniform methods that often yield different values for closely related species. Based upon the literature and the results of field studies in the Little Cypress Basin, Texas, and the Yazoo River, Mississippi, closely related species of warmwater fishes were placed into groups. For each group, a community model was developed based on five variables: percent pools, average current velocity, percent cover, pH, and dissolved oxygen. Results are compared with the unmodified models, and methods used to develop and test these models are discussed. Keywords: Habitat evaluation, Environment.
