I have been studying the pikeminnow reward program. Including the comments posted here and all over the internet.
I am in the process of writing a book, not intended for publication, but for my own use.
Most of the comments posted are only about half right. There are a number of watersheds containing NPM.northern pike minnow. Each with its own specific problems.
Columbia/Snake
Sacramento
Eell River
Colorado
Etc.
BPA is under a court order to mitigate, not eliminate npm. The reward program is the result. The objective is to cull 10 to 20 percent of the npm large enough to eat significant salmon smolts, in a given year. IE reduce predation by 50 percent. Complaints that the program is imperfect, are just that...complaints.
Not solutions.
If want to know, not just speculate it is nessesary to read the detailed reports, annual and independent.
I will post a list with links one of these days, soon.
