The Top Contenders for Shellfish Protein
When evaluating which shellfish offers the highest protein content, it is important to consider the serving size and preparation method. While no single shellfish is definitively the highest in all contexts, some consistently outperform others on a per-gram basis. Among the most impressive are clams, shrimp, and scallops, each offering a substantial protein boost with minimal fat and calories.
Clams: A Protein Powerhouse
Clams often emerge as one of the top protein contenders in the shellfish category. Certain sources indicate that clams can offer up to 25.5g of protein per 100g serving, making them particularly potent for muscle repair and recovery. Beyond their high protein count, clams are exceptionally rich in vitamins, especially B12, and contain more iron than beef. They are also a good source of omega-3 fatty acids, making them a well-rounded nutritional choice. Clams are highly versatile and can be steamed, grilled, or added to soups and pasta dishes like spaghetti alle vongole.
Shrimp: The Lean and Versatile Option
Shrimp are a widely popular seafood choice known for their lean protein content. A 3-ounce (around 85g) serving of cooked shrimp provides roughly 24 grams of protein, while being remarkably low in fat and calories. They are also a good source of iodine, which is essential for thyroid health, as well as selenium and vitamin B12. The high protein and low fat make shrimp an ideal option for those seeking to build lean muscle or manage their weight. Shrimp can be quickly sautéed, grilled, or boiled and added to stir-fries, salads, or pasta for a fast, protein-rich meal.
Scallops: Small but Mighty
Scallops are another powerful source of lean protein. Various sources cite cooked scallops as providing 20 to 24 grams of protein per 3 to 4-ounce serving. They have a sweet, buttery flavor and are very low in fat and calories, similar to shrimp. Scallops also provide key minerals like selenium and zinc, which are crucial for a strong immune system. They cook quickly and can be seared or grilled to bring out their natural flavor. The combination of high protein and delicate taste makes scallops a favorite for healthy gourmet meals.
Other Notable High-Protein Shellfish
While clams, shrimp, and scallops are top contenders, other shellfish also offer significant protein. Lobster, for instance, provides about 19 grams of protein per 3-ounce portion and is also packed with omega-3s, phosphorus, and vitamin B12. Crab meat, such as that from the Alaskan king crab, offers about 26 grams of protein in a similar serving size and is rich in zinc and B vitamins.

Maximizing Nutritional Benefits from Shellfish
To ensure you are getting the most protein and nutrients, pay attention to how you prepare your shellfish. Steaming, grilling, or baking are healthier cooking methods that preserve the lean protein profile and keep fat content low. Conversely, breading and deep-frying add significant calories and saturated fat, diminishing the health benefits. Incorporating shellfish into salads, stews, or pasta dishes is an excellent way to boost your protein intake.

Conclusion
When it comes to answering which shellfish is the highest in protein, the answer isn't a simple one. Based on various nutritional data, clams and shrimp often provide the most protein per serving, with scallops and lobster not far behind. The best choice ultimately depends on your dietary goals, taste preferences, and the rest of your meal plan. However, incorporating any of these shellfish into a balanced diet is a fantastic way to boost your lean protein intake and gain a wide range of other essential nutrients.
A Note on Shellfish and Mercury
Concerns about mercury levels in seafood are common. Most shellfish, including clams, shrimp, and scallops, are on the low-mercury list, making them safe choices to include regularly in your diet. The USDA and FDA offer guidelines on safe seafood consumption, recommending 1-2 servings per week as part of a healthy diet.
Final Thoughts on Protein and Shellfish
From the high-protein lean meat of shrimp to the impressive nutrient profile of clams, shellfish offers something for everyone. They are an accessible, nutrient-dense source of high-quality protein that can support muscle growth, provide energy, and contribute to overall health. Whether you choose the versatile shrimp or the mineral-rich clam, you can be confident that you are making a healthy dietary choice.
