You're off by a factor of over 20. A reasonable ballpark estimate for the total mass of a shrimp is 10g. The amount of usable meat is less (though in a survival scenario you would eat the whole thing, head included). Hell, the average meat yield from a standard size blue crab is only around 60g.

You would need to eat netfulls of shrimp per day to meet caloric requirements, not just ten! Anecdotally, I can toss back dozens of appetizer shrimp and still be hungry for a main course.
