This paper tabulates the sterol, phospholipid, mineral content and the proximate composition of fifteen species of freshwater fish [Bass, Rock (Ambloplites rupestris); Bass, White (Morone chrysops); Bullhead, Brown (Ictalurus nebulosus); Burbot (Lota lota); Carp (Cyprinus carpio); Crappie, Black (Pomoxis nigromaculatus); Drum, Freshwater (Aplodinotus grunniens); Perch, White (Morone americanus); Perch, Yellow (Perca flavescens); Pike, Northern (Esox lucius); Pike, Walleye (Stizostedion vitreum); Smelt, American (Osmerus mordax); Sucker, White (Catostomus commersonni); Sunfish, Pumpkinseed (Lepomis gibbosus); Trout, Brook (Salvelinus fontinalis); Trout, Lake (Salvelinus namaycush); Trout, Rainbow (Salmo gairdneri)]. The fish contained an average 78, 19 and 1.1 percent moisture, protein and ash, respectively. Potassium, phosphorus and calcium averaging 400, 200 and 100 mg/100 g filet were the predominant mineral components. The lipid contents of filets ranged from 0.7 for rock bass to 7.2 for lake trout with most species averaging around 2.0% lipid. Phospholipids ranged from 185 to 875 mg/100 g filet and showed an inverse relationship to the total lipids. Cholesterol was the only sterol present and averaged 70 mg/100 g filet. Cholesterol showed a weak correlation with protein content of filet.
