Hmmmm, it seems like it's missing some useful info - it's very ocean-centric and doesn't say much about fish found in freshwater lakes (aside from the Great Lakes). What about the western and inland fish? And don't tell me it's an ocean-only site because they do have lake fish in their lists.
Here's a short list of some of the commonly eaten fish that are missing:
1. Mountain Whitefish (plentiful)
2A. Bull Trout (at-risk). The site only mentions Steelhead and Rainbow.
2B. Brook Trout.
2C. Brown Trout.
2D. Lake Trout.
3. Arctic Grayling.
4. Lake Whitefish (eaten a lot, fairly plentiful fish).
5. Northern Pike. (very plentiful, eaten often by people who fish lakes). Also known as Jackfish.
6. Burbot. (good population)
