Common Fish and Seafood Portion Weights

Recipes and macro trackers ask for fish by weight, not by fillet. Use this chart for a single standard portion of the most common species.

Fish / seafoodTypical portionWeightProtein
Salmon fillet1 fillet170 g37 g
Tuna steak1 steak150 g42 g
Cod fillet1 fillet140 g25 g
Tilapia fillet1 fillet115 g26 g
Shrimp (large)4 pieces85 g20 g
Salmon (whole, small)1 fish900 g

Protein figures are for the cooked portion. Whole-fish weight includes head, bones, and skin (roughly 45% is edible fillet).

Weigh Your Catch Without a Fishing Scale

Landed a nice fish but left your fishing scale at home? Our AI estimates the weight of your catch from a photo. Hold the fish up or lay it on a flat surface next to a known reference object like a rod handle or your hand, and get a weight estimate to brag about or log in your fishing journal.

Estimate Fish Fillet Weight for Recipes

Many fish recipes specify fillet weight in grams or ounces. Whether you are preparing salmon, cod, tilapia, or any other fish, a quick photo gives you the weight you need for perfect recipe execution. Place the fillet on a cutting board and photograph from above for the best accuracy.

Whole Fish vs Fillet: What You Actually Eat

A whole fish weighs far more than the meat you serve. After removing the head, bones, skin, and innards, only about 45 percent of the total weight remains as edible fillet. Keep that in mind when a recipe calls for a fillet weight but you bought the fish whole: the chart above shows a small whole salmon at 900 g yielding roughly 400 g of fillet.

Works with All Types of Fish and Seafood

From freshwater trout to ocean-caught tuna, from shrimp to lobster, our AI recognizes and estimates the weight of a wide range of fish and seafood species. The tool adjusts its estimate based on the identified species, since density and body shape vary significantly between different types of fish.
