I Honestly dont think Bears like to eat a lot of dead fish, most of the year. I know this sounds crazy but I hunt directly across from a fish hatchery. Around September and October there are hundreds of dead fish lining the river, as well as lots of ripe blackberry bushes. None of these dead fish ever get eaten by bears, they end up getting eaten by birds and coyotes that is it. The bears that we have shot in this area taste great and have never had any fish in their stomachs. On the other hand, I shot a bear at 5,000 feet a couple years ago and it tasted like crap.
