The Core Difference: Whole Fish vs. Fillets
The most important factor in determining how many servings you will get from a pound of fish is the cut. A pound of whole fish, purchased with the head, tail, and bones intact, will yield a much different amount of edible meat than a pound of clean, boneless fillets. This is because a significant portion of the weight in a whole fish is discarded during preparation.
Whole Fish: Roughly one entree serving per pound
When purchasing a whole fish, such as branzino, snapper, or sea bass, the general rule of thumb is to buy one pound of raw fish per person for a main course. For example, a single 1-pound fish is considered a generous entree portion for one diner. This accounts for the approximately 60% of the fish's weight that will be lost from bones, head, and guts. If you are buying a larger whole fish to serve a group, a 9- to 11-pound fish would be appropriate for feeding 10 people.
Fish Fillets and Steaks: Up to four servings per pound
In contrast, fillets and steaks are sold with the head, bones, and other parts already removed, so almost all the weight is edible. For this reason, a single pound of fillets goes much further. Most sources recommend a raw portion of 6–8 ounces per person for a main course. This means a 1-pound (16 oz) package of fillets, like cod, tilapia, or flounder, will provide two standard entree servings. Some fish, like salmon, have higher fat content and are very rich, so a 3.5 to 4-ounce cooked serving is often considered standard, allowing one pound of raw salmon fillets to feed up to four people. Appetizer or starter portions are even smaller, typically 3–4 ounces raw weight per person.
Factors Affecting Your Fish Portions
Beyond the cut, several other variables can influence how many servings you get from a pound of fish. Planning for these factors can help you avoid waste and ensure everyone leaves the table satisfied.
Here are some key considerations:
- Other meal components: If fish is the centerpiece of a substantial meal with several heavy side dishes, you may not need as much per person. For a meal with lighter sides, you might increase the portion size.
- Appetite of diners: Larger or heavier eaters will naturally consume more, so it may be prudent to add an extra serving's worth of fish to your purchase.
- Cooking method: The way you prepare the fish can affect its final weight and moisture content. For instance, fish cooked in a dry-heat method may lose more moisture than steamed or poached fish.
- Type of fish: The richness and texture of the fish also play a role. A rich, oily fish like salmon might feel more filling in a smaller portion than a lean, white fish like cod.
The Cooking Process and Yield
It is important to remember that all serving size recommendations are based on raw weight. As fish cooks, it will lose some of its weight, primarily in the form of moisture. A standard portion is typically considered 4 ounces after it has been cooked. To account for this moisture loss, it is always a good idea to purchase a bit more raw fish than you think you will need, especially if you plan on having leftovers.
Serving Size Comparison Table
| Fish Cut | Portion Size (Raw Weight) | Approx. Servings from 1 lb | Consideration |
|---|---|---|---|
| Whole Fish | ~16 oz (1 lb) | 1 | High discard from bones, head, and guts |
| Fillets (Lean White) | 6–8 oz | 2 | Little to no waste |
| Fillets (Oily/Rich) | 4–6 oz | 3–4 | Higher richness means smaller portions are satisfying |
| Steaks | 6–10 oz | 2 (or 1-2 for large appetites) | Depends on steak thickness and appetite |
| Appetizer Portions | 3–4 oz | 4 | Serves as a starter, not a main course |
Calculating Portions for Different Recipes
Fish Tacos: For recipes like fish tacos or sandwiches where the fish is part of a larger ensemble, you can use a smaller portion. Aim for 3 to 4 ounces of raw fillet per person, which means a pound of fillets could serve up to four people. This leaves plenty of room for all the toppings and side fixings.
Baked or Grilled Fillet: When the fish is the main protein on the plate, stick to the 6 to 8-ounce raw weight guideline. For two people, you would need a 1-pound fillet. For a group of four, a 2-pound fillet would be sufficient.
Fish Stew or Soup: When incorporating fish into a stew, the serving size can be adjusted based on the proportion of other ingredients. A general rule of thumb is to use 4 to 6 ounces of raw fish fillet per serving. Because fish is part of a larger, more substantial dish, smaller portions are appropriate.

Conclusion
Determining how many servings are in one pound of fish is not a one-size-fits-all calculation. The key takeaway is to always consider the cut of the fish first, as this is the most critical factor. For a single pound, expect to feed one person generously if using a whole fish. If you are cooking with boneless fillets or steaks, a pound can easily feed two to four people, depending on the meal's context and the richness of the fish. By understanding the yield of different cuts and accounting for factors like cooking and appetite, you can confidently plan your meals and purchase the perfect amount of fish every time.
