Catfish is a popular freshwater fish known for its mild flavor and firm texture, but how much protein does it actually deliver? This calculator helps you determine the protein content in catfish based on your serving size and preparation method. Whether you're tracking macros, planning a high-protein diet, or just curious about the nutritional value of your dinner, this tool gives you accurate estimates in grams and calories.
Simply enter the weight of your catfish portion, choose the unit (grams, ounces, or pounds), and select how it's prepared — raw, baked, fried, or grilled. The calculator uses standard USDA nutrition data to compute protein, calories, and fat per 100g, then scales it to your portion. You'll also see a breakdown of protein per serving and per 100g, making it easy to compare with other protein sources.
Perfect for athletes, bodybuilders, and anyone following a high-protein meal plan, this tool takes the guesswork out of portion sizing. Use the quick-fill buttons for common serving sizes, or enter your exact weight for precise tracking.

How to Use This Tool
Using the catfish protein calculator is straightforward. Start by entering the weight of your catfish portion in the input field. You can choose between grams, ounces, or pounds using the dropdown next to the input. Next, select the preparation method that matches how your catfish is cooked — raw, baked/broiled, fried (breaded), or grilled. The calculator then uses standard nutritional data to estimate the protein, calories, and fat content for your specific serving.
For quick reference, the tool includes preset buttons for common serving sizes like 100 g, 150 g, 200 g, and 8 oz. Clicking one of these automatically fills the weight field and sets the unit to grams (or ounces for the 8 oz button). This is handy when you're following a recipe or a meal plan that specifies a typical portion.
After clicking the Calculate button, you'll see the total protein in grams, along with a breakdown of calories and fat. The result also shows the protein per 100g for the selected preparation, which helps you compare catfish to other protein sources. Use the Reset button to clear all inputs and start a new calculation.
Nutritional Profile of Catfish
Catfish is a lean source of protein, making it a popular choice for those looking to increase their protein intake without excessive fat. A 100-gram serving of raw catfish contains approximately 17.4 grams of protein, 2.9 grams of fat, and about 95 calories. When cooked, the protein content per 100g increases slightly because water is lost during cooking, concentrating the nutrients. For example, baked or grilled catfish provides around 20.1 grams of protein per 100g, while fried catfish (with breading) offers about 18.2 grams but significantly more calories and fat due to the oil and coating.
Catfish is also rich in essential nutrients like vitamin B12, selenium, and phosphorus. It's low in mercury compared to many other fish, making it safe for regular consumption. However, the exact nutritional values can vary based on the fish's diet, farming practices, and cooking method. The figures used in this calculator are based on USDA FoodData Central averages, which are widely accepted for dietary planning.
Formula Explained
The calculation is simple: the calculator takes the weight you enter, converts it to grams if necessary, and then multiplies the per-100g values by the ratio of your serving to 100 grams. For instance, if you enter 150 grams of baked catfish, the protein is calculated as (150 / 100) × 20.1 = 30.15 grams. The same logic applies to calories and fat.
This proportional scaling assumes that the nutritional composition is uniform throughout the fish, which is a reasonable approximation for most fillets. Keep in mind that if you're eating a whole fish with bones and skin, the edible portion will be less than the total weight. In that case, you may want to weigh only the edible meat for more accurate results.
Worked Examples
Example 1: You have a 6-ounce (170 g) grilled catfish fillet. Using the calculator, select 'grilled' and enter 170 g. The protein would be (170/100) × 20.1 = 34.2 g. Calories: (170/100) × 130 = 221 kcal. Fat: (170/100) × 5.0 = 8.5 g.
Example 2: You're meal-prepping and use 250 g of raw catfish. Select 'raw' and enter 250 g. Protein: (250/100) × 17.4 = 43.5 g. Calories: (250/100) × 95 = 237.5 kcal. Fat: (250/100) × 2.9 = 7.25 g.
Example 3: A fried catfish fillet weighs 4 oz (113 g). Select 'fried' and enter 113 g. Protein: (113/100) × 18.2 = 20.6 g. Calories: (113/100) × 195 = 220.4 kcal. Fat: (113/100) × 11.3 = 12.8 g.
Tips for Accurate Tracking
- Weigh your catfish after cooking if you're tracking cooked portions, as water loss changes the nutrient density.
- If you're using a recipe with breading or marinades, remember that these add extra calories and carbs. The 'fried' option accounts for a standard breaded coating, but homemade versions may vary.
- For the most precise results, use a kitchen scale rather than estimating portion sizes by eye.
- Compare catfish to other protein sources like chicken breast or tilapia to diversify your protein intake. You can use our tilapia iron calculator for a similar fish, or check the scallop protein calculator for shellfish options.
Frequently Asked Questions
Is catfish a good source of protein? Yes, catfish is an excellent source of high-quality protein, providing all essential amino acids. A 100g serving of cooked catfish offers about 20g of protein, which is comparable to chicken breast.
Does cooking method affect protein content? The protein content per 100g increases slightly when cooked because water evaporates, concentrating the nutrients. However, the total protein in the piece remains the same; only the density changes.
Can I use this calculator for other fish? No, this calculator is specifically calibrated for catfish. Different fish have different nutritional profiles. For other types, you might want to use a general nutrition calculator or check specific tools like the tuna calorie calculator.
How accurate are the values? The values are based on USDA FoodData Central averages and are accurate within a reasonable range. Actual values can vary due to factors like fish size, diet, and cooking time.
