I'd pass on the canned fishy stuff purelife. It's hard to rid your campsite of the bear-bait aroma. Even washing, wrapping and bagging the used cans isn't enough. (burning them out is good if campfires are allowed)
Think about bringing dried foods over canned foods. Noodles, soups, cereals etc. Pancake mix for brekky. Hot dog weenys or meats with burnable wrappers is good..... (again, if campfires are even allowed at this time).
