"A California study reported that 532,000 hatchery salmon consumed 7.5 million wild chinook fingerlings in the Feather River."

How do you suppose they got these numbers? Do you suppose they killed the 532,000 hatchery salmon and opened them up? Did they count the hatchery salmon they killed with no fish in their stomach?

Perhaps all the fish were dumped into a tank, and when all the 7.5 million wild chinook were gone, they said, "That's it!"?

I'm trying to laugh at this.....but it's hard not to be sceptical. Sounds pretty "creative" to me.
