Crazy amount of info in that paper.
The white chinook benefits aspect was most interesting to me.
"Under experimental conditions, red eggs experience greater predation relative to white eggs, and in a high predation environment, the advantage of reduced predation risk in white eggs is predicted to outweigh the expected cost of their lower incubation survival"
And
"In addition, morphs display differences in sexual selection, as evidence suggests that red females employ pre-spawning mate choice and white females use cryptic processes (post-spawning) to bias paternity of their eggs in favour of males of their own colour morph"
