Elaboration of a water ichtyologic potential index

Science of The Total Environment, 1992
A model has been developed, using physico-chemical data, in order to quantify the quality of surface waters and their ichtyologic potential: the WIPI model (Water Ichtyologic Potential Index). Many physico-chemical parameters, useless if considered individually, can be of practical interest for pisciculture (e.g., an explanation of systematic fish ...
