When you flash a recipe up calling for 2lbs of shrimp, um, well, obviously not carrying that, or all the other freshies. JTC, no on the trout grit thing. It doesn't even sound appetizing. The trout can't stand up to it. Needs to be a secondary dish (the trout). They're always best separate and on their own merits anyway.
As much as the shrimp thing sounds nice, so does just cheese and summer sausage/salami.

They do make an outstanding backcountry breakfast. In Boy Scouts, we used to go on week long canoe camping trips on meandering coastal plains rivers (which were isolated wilderness areas). We'd get up and catch fresh red fin or blue tail bream, have them sauteed in butter with scrambled eggs and a big batch of grits for breakfast. Man, my mouth's startin' to water!
