Elaboration of a water ichtyologic potential index

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 mortalities, elaboration of guidelines for new pisciculture). The water quality is expressed in terms of an eight-step scale that provides a guide evaluation of the ichtyologic potential.
