Use of fish distribution modelling for river management

► We modelled decision trees to predict the distribution of the pike in Flemih streams. ► The prediction of the pike was acceptable based on two model evaluations. ► Nevertheless the prediction will be further improved by including more variables. ► The habitat variables had more contribution to the prediction of pike than the water quality ones. ► These models can as such encourage river managers to make the necessary investments and/or activity changes as desired by society.
