Component 1.1 : Productive capacity of fish habitats in rivers

Objectves :

The objectives of the Productive Capacity of Fish Habitats in Rivers component are:

  • to provide metrics of productive capacity of fish habitats (PCFH; by species and life-stages) for a series of riverine ecosystems (this data will form the basis for the analysis of the relationships between PCFH and chemical, physical, and biological drivers for the complete network);

  • to develop Habitat Quality Models (HQM) for all fish species and life-stages of the study sites, and to assess the relative role of local, contextual, and ecosystemic environmental conditions on predictions made by HQM;

  • to assess the existence of relationships between phenotypic traits of fish, metrics of PCFH, and the environmental conditions used by different combinations of fish species and life-stages; and,

  • to test the hypothesis that HQM developed at different sites may vary with fish density.
