I don't claim it's a perfect analogue, nor are any of my numbers better than what I could find in a quick search. (Even then, I had to go through a lot of sites giving calories per cup of cooked rice to find a figure for uncooked.) It's just a ballpark calculation to see if the numbers in the original post were reasonable.

Don't forget the arm-chair exercise of lifting beer to face.

Ironically, beer probably contains more proteins and calories than some of those fish you're trying to catch, depending on how many beers you've had while catching (or not) one. Oh, and it doesn't have mercury in it.
