The funny thing about this logic that the bonk everything people talk...the fact that they do sit down stream and eat eggs,,,the eggs that are drifiting out of the red are wasted eggs any way, most are not fertilized and hardly any well become fry....If you realy want to kill something that effects the return of salmon, kill a cormorant. they eat there weight EACH DAY in smolt....thats my soapbox...DJ
