A 6oz serving of Atlantic Mackerel can contain over 445 calories, making it a frontrunner for the fish with the highest calories. This dense energy comes from its high concentration of healthy fats, highlighting that not all fish are low-calorie choices.

According to USDA data, Atlantic mackerel contains approximately 205 calories per 100-gram serving, making it one of the highest-calorie fish available. This high energy content is primarily due to its rich supply of healthy fats, which also makes it a powerhouse of beneficial omega-3 fatty acids.
