Shellfish cooking loss runs 20–25%. Moisture evaporates fastest on high heat (Sobral et al., Compr Rev Food Sci Food Saf 2021). Per 100 g: 71 kcal, 13.6 g protein, 566 mg sodium. Pre-cooked retail shrimp is already at cooked weight.
How should I track Shrimp, mixed species, raw (may contain additives to retain moisture)?
Shrimp, mixed species, raw (may contain additives to retain moisture) is a good source of protein. For the most accurate tracking of Shrimp, mixed species, raw (may contain additives to retain moisture), weigh it raw and boneless. Fish loses 15–25% of its weight during cooking as water evaporates (USDA cooking yield data). If you are using canned fish, the drained weight is what matters — the difference between oil-packed and water-packed can be 40–80 calories per can. A quick drain-and-weigh habit saves you from hidden calories. Also keep in mind that smoked or cured fish has different values than fresh due to moisture loss and added salt.
