You may be right that the majority is plant matter, but in salmon season bears gather at salmon runs and waste little energy in snatching fish as they leap up the cascades. See [1]. (Although individual bears do compete for the best fishing spots, they are in a "fish in a barrel" situation when they get one. They don't have to chase anything, just grab and chew.)

Edit to add:
Here's an article [2] from 2018, How many salmon will a bear eat?
Excerpt: Adult male bears on Kodiak ate the most salmon on average, consuming an incredible 6,146 pounds (2,788 kg) per bear per year! Adult females ate 3,007 pounds (1,364 kg). Salmon consumption varied among subadult bears, independent juvenile bears between 2.5 and 5.5 years old. Subadult females ate 1,248 pounds (566 kg) while subadult males ate 1,305 pounds (592 kg) of salmon per bear per year.

- nradov 5y agoThe bears catch so many salmon on some rivers that they eat only the most nutritious parts and leave the rest of the carcass for scavengers.
- AlbertCory 5y agoCorrect. See my post and [1]. I saw this behavior myself. It's not just standing and snatching fish out of the stream, though. Most bears have to chase the fish and try to catch them, often failing. [1] https://photos.app.goo.gl/mXMHAjDyQNDjFqjw8 https://photos.app.goo.gl/mXMHAjDyQNDjFqjw8
- mtnGoat 5y agocosts a lot to feed bears. this years salmon price is estimated at $14-20\lb. if we take the average, a bear eats more then $100k a year worth of salmon.
- AlbertCory 5y agoIt's cheaper when you buy it near the source.
- mtnGoat 5y agoTrue, and probably cheaper buying in that kind of bulk. Still an impressive amount of fish.
- monocasa 5y agoAlso, breaking down plant matter is very energy intensive. Salmon is very close to what animals need, sort of by definition.
