For the purposes of integrated river and fisheries management it is vital to understand the critical factors which affect the distribution and abundance of coarse fish species in lowland rivers. Consequently, mechanisms for determining the specific habitat and environmental needs of coarse fish species living in rivers are required. To meet this requirement, computer models, which correlate environmental and fisheries data have been developed. The project team adapted two fisheries community modelling techniques to meet the specific needs of this study. The approaches were: Habitat suitability Index (HSI) models; Multivariate statistical methods (CANOCO, TWINSPAN and DISCRIMINANT).
