Habitat suitability index models: flathead catfish (Pylodictis olivaris)

The habitat use information and Habitat Suitability Index (HSI) models presented in this document are intended for use in impact assessment and habitat management activities. Literature concerning the habitat requirements and preferences of flathead catfish is reviewed and then synthesized into HSI models, which are scaled to produce an index between 0 (unsuitable habitat) and 1 (optimal habitat). Assumptions used to transform habitat use information into these quantitative models are noted, and guidelines for model application are described. Other habitat models found in the literature are presented.
