Cross-Ecotype Production

Notes:

The proportion of offspring that smolt or residualize was estimated from breeding studies conducted in the Grande Rhonde basin (Rich Carmichael, personal communication). As expected, parental crosses between anadromous females and anadromous males produced the highest proportion of offspring that smolt, while pure resident crosses produce the lowest proportion of offspring that smolt.
