Jackfish is a fish, and the figures here describe it raw. It mainly provides protein, with some fat, alongside vitamins and minerals. Per 100g, it contains 22g of protein, 2.4g of fat, 13µg of vitamin D and 5µg of vitamin B12. It also supplies minerals including phosphorus, potassium and iodine.

Protein contributes to the growth and maintenance of muscles and other body tissues. Vitamin D helps the body absorb calcium and supports bones and muscles, while vitamin B12 is needed for normal nerve function and red blood cell formation. Cooking methods and added ingredients can change the nutritional content, particularly fat and salt. Full nutritional figures for raw jackfish are in the tables below.
