Spawning Bed Analysis and Site Selection

 
 

 

         
   

Performing riverbed analysis and site selection of preferred egg planting sites

Prior to conducting wild salmon survival enhancement activities, a careful study and assessment of physical, chemical, and hydrological attributes of available spawning beds should be undertaken.

Analysis of the hyporheic zone (gravel beds in which salmon spawn) is conducted to identify and catalog the areas most conducive to high egg survival. Steps are taken to prevent displacement of other species in selecting egg planting sites.

Assessing the health of the spawning habitat is a principal consideration in egg planting: “The selection of egg planting sites is a function of careful analysis of the hyporheic zone through freeze core sampling and establishing the “Fredle” index. Only when this work is complete can we confidently predict high survival of egg plants.” (White, 1980)

Alliances with agencies, tribes and community organizations, with guidance from our board of directors realizes a collaborative atmosphere that strives to combine the most recent findings in habitat studies with years of practical knowledge and experience of each unique watershed and salmon stock.
