The count gives you the number of shrimp you can expect to get in one pound. The fewer shrimp per pound, the larger and more expensive they are. Some of the standard sizes you'll find are: 61-70, 51-60 Really small shrimp, often used for shrimp salad. Often labeled Tiny, Extra Small and Small. 43-50, 36-42 Labeled medium or medium large. I'd use these in pasta or mixed seafood dishes.
