The Great Lakes are home to a variety of fish, including trout, bass, sturgeon and sucker fish. Although the sucker fish may not be as popular as other fish, it is a tasty source of protein and other essential nutrients. The fish that you eat should only be from clean waters, and it has the most health benefits when you eat it in moderation as part of a balanced diet.

The white sucker, or Catostomus commersoni, is also known as the common, eastern or grey sucker, the mullet or bay fish, according to the University of Wisconsin. It is native to Lakes Michigan, Huron, Erie, Ontario and Superior, and it can grow up to 20 inches in length and 4 lbs. in weight. White sucker is just as edible as other fish, and its name may help explain its lack of popularity. You can use it fresh or preserve it after you catch it.
Each serving of 159 g, or nearly 6 oz., has only 146 calories, 3.7 g total fat and 0 g carbohydrate. The white sucker provides 27 g high-quality protein. Each serving has 604 mg potassium and 64 mg sodium, and a high-potassium, low-sodium diet can help you control your blood pressure, according to the 2010 Dietary Guidelines from the U.S. Department of Health and Human Services. The fish has 111 mg calcium, or 11 percent of the daily value, 2 mg iron, or 11 percent of the daily value, and 3.2 mcg vitamin B-12, or 53 percent of the daily value.
Fats and Cholesterol
The white sucker has only 0.7 g cholesterol-raising saturated fat, and it provides 0.3 g eicosapentaenoic acid, or EPA, and 0.5 g docosohexaenoic acid, or DHA. EPA and DHA are long-chain omega-three fats, from fat in fish, which may lower your risk for cardiac death. Healthy adults should eat two servings of seafood per week to meet recommendations in the 2010 Dietary Guidelines from the U.S. Department of Health and Human Services. The white sucker is high in cholesterol, with 65 mg per serving, and healthy adults should have no more than 300 mg per day.
You can eat fresh white sucker just as you would eat other white fish, such as grilled, baked or in soups, chowders and stews, according to the University of Wisconsin. You can freeze fresh white sucker for later use, and the University of Minnesota recommends freezing it as soon as possible after catching it. Follow standard safety precautions for canning to avoid contamination with Clostridium botulinum. Another option is to brine and smoke the fish.
