Trout

All fish use this graphic.

Trout, along with salmon, are the biggest fish you can catch in the game. They can only be caught in deep water or rivers, and fishing in rapids may give a better chance of catching them. 1 lb of trout can fill nearly all of your hunger bar. Each trout is usually 4-5 lbs, and can be caught in nets.

A pile of 19 6-pound salmons cost one cord to dry or smoke, same as 19 perches or 19 meat cuts. Therefore it's most economical to dry/smoke salmon/trout instead of meat, though it may take a lot of time and equipment to procure more than just a few.
