Understanding the 'Count Per Pound' System
In the seafood industry, shrimp size is standardized using a "count per pound" system, often printed directly on packaging or displayed at the seafood counter. The number indicates the approximate quantity of shrimp required to make one pound (16 ounces). The golden rule is: the smaller the number, the larger the shrimp. For example, shrimp labeled "31/40" means there are approximately 31 to 40 shrimp in one pound, making them 'Large'. Using this system, we can accurately determine the approximate number of shrimp in an 8-ounce serving.
Raw Shrimp Count for 8oz
To find the number of raw, unpeeled shrimp in an 8oz portion, simply divide the count per pound range by two. For instance:
- Jumbo (21/25 count): An 8oz serving contains roughly 10 to 12 jumbo shrimp.
- Large (31/35 count): Expect about 15 to 17 large shrimp in 8 ounces.
- Medium (41/50 count): Your 8oz portion will have approximately 20 to 25 medium shrimp.
- Small (51/60 count): A full 8oz is equivalent to about 25 to 30 small shrimp.
The Impact of Cooking on Weight
It is crucial to remember that shrimp loses weight during the cooking process, mainly due to moisture loss. Raw, shell-on shrimp can lose up to 20% or more of their weight when cooked and peeled. This means if your recipe calls for 8 ounces of cooked shrimp, you will need to purchase more than 8 ounces of raw shrimp to compensate for the weight reduction. This weight difference also explains why cooked, pre-packaged shrimp might seem to be a better deal, but a direct comparison requires paying close attention to the count-per-pound label to ensure you are truly getting the same product size and quantity.
Shell-on vs. Peeled and Deveined Weight
Another significant factor affecting your 8oz portion is whether the shrimp are sold with or without the shell. The shell and head can account for a substantial portion of the total weight. When purchasing shell-on shrimp, you must account for the weight of the inedible parts. For example, 8 ounces of raw, shell-on shrimp will yield a smaller amount of cooked meat compared to 8 ounces of raw, peeled, and deveined shrimp.
Comparison of Shrimp Sizes for an 8oz Portion
To simplify your meal planning, here is a table comparing different shrimp sizes and the approximate count you can expect in an 8oz raw, peeled, and deveined portion.
| Common Sizing Term | Count per Pound (Raw, Unpeeled) | Approx. Count in 8oz (Raw, Peeled) | Best Uses |
|---|---|---|---|
| Colossal (U/15) | Under 15 | 6-7 | Shrimp Cocktail, Grilling Skewers |
| Jumbo (21/25) | 21-25 | 10-12 | Sautéing, Grilling, Pasta dishes |
| Extra Large (26/30) | 26-30 | 13-15 | Stir-fries, Scampi |
| Large (31/35) | 31-35 | 15-17 | Salads, Tacos |
| Medium (41/50) | 41-50 | 20-25 | Soups, Pasta sauces |
| Small (51/60) | 51-60 | 25-30 | Salads, Bisque, Ceviche |
Practical Tips for Measuring and Buying Shrimp
- Read the Label: Always check the "count per pound" number on the package rather than relying solely on vague terms like "jumbo" or "large," as these can vary between brands.
- Consider the Recipe: The appropriate size of shrimp for 8 ounces depends on your dish. Larger shrimp are better for grilling or cocktail, while smaller ones are ideal for stir-fries and pasta.
- Account for Cooking Loss: When a recipe specifies a cooked weight, purchase a slightly higher raw weight to account for moisture and shell loss. A good rule of thumb is to add 25% to your raw weight if you are cooking with the shell on.
- Thaw Properly: For frozen shrimp, use the cold-water method to thaw them correctly, which helps preserve their texture and prevents them from getting mushy.
- Storage: Store fresh shrimp on ice in the refrigerator and use them within one to two days. Cooked shrimp can last in the fridge for up to five days.
Conclusion
In conclusion, the question of how much shrimp is 8oz is not straightforward and depends entirely on the size of the shrimp. By understanding the standard "count per pound" system, accounting for weight loss during cooking, and considering whether the shrimp are peeled or shell-on, you can accurately determine the right quantity for your recipe. This knowledge ensures you purchase the correct amount of shrimp every time, whether you are making a delicate shrimp scampi or a hearty seafood boil.

Final Summary
So, how much shrimp is 8oz? It depends on the count. An 8oz serving can contain anywhere from 6-7 colossal shrimp to 25-30 small shrimp. The number is influenced by the raw vs. cooked state and whether the shell is on. Always check the count-per-pound label to get the right amount for your dish.
