Well, the nutritional information on tilapia is a bit inconsistent across several sites. For a 100 gram/3.5 oz. serving, the calories seem to range from 82 to over 96.

This seafood store says that tilapia has "93 calories in a 3-1/2 oz. portion and 1.1 grams of fat." That would give it about 20.7g protein. They list some counts for other fish and seafood as well.

The University of FL says that "Approximately four ounces [roughly 115g] of raw edible portion yields 110 calories, 2.5 g total fat, .5 g cholesterol, 55 mg sodium.~ It also contains 1 g total carbohydrate, 21 g Protein, Vitamin A-2% *DV, Calcium-6% DV and Iron- 2% DV."

I'm not sure where that 1g of carbs is coming from, though!
