No. Kolyoz is chub mackerel, a different species from Atlantic mackerel; the two names are sometimes confused. Both are oily mackerels and can work in similar recipes, but they are not interchangeable names for the same fish.
Kolyoz works well grilled, baked, or pan-fried because its oily flesh stays flavorful during cooking. Pat it dry first and avoid overcooking, which can make the meat dry. Lemon, herbs, and a little salt are simple seasonings that suit it.
Kolyoz has a central backbone and smaller pin bones, so it is not a boneless fish. Remove the backbone after cooking or ask the fishmonger to fillet it; check each portion carefully before serving it to a child.
Kolyoz has a rich, savory taste and firmer, darker flesh than many mild white fish. Its flavor is strongest when fresh, and grilling or baking with lemon can complement it without masking the fish.
Yes, kolyoz is an oily fish and a source of omega-3 fats, as well as protein and vitamin B12. Baking or grilling it keeps preparation simple; the amount of added oil depends on how you cook it.
Kolyoz should not be eaten raw unless it has been handled and prepared specifically for raw consumption. Freezing at home does not guarantee that parasites or harmful bacteria are eliminated, so cooking it thoroughly is the safer choice.
Refrigerate cooked kolyoz promptly in a covered container and keep it separate from raw seafood. Eat it within a few days, and discard it if it has been left at room temperature for too long or develops an unusual smell.
Yes, you can freeze kolyoz after cleaning and drying it. Wrap it tightly to limit air exposure, thaw it in the refrigerator, and cook it soon after thawing; do not refreeze it raw once thawed.
Kolyoz contains some mercury, but it is not the same fish as high-mercury king mackerel. Mercury varies among fish and with fish size, so pregnant people should follow current local seafood guidance when choosing how often to eat it.
Fresh kolyoz should have clear, bright eyes, firm flesh, and a clean sea-like smell. Avoid fish with a sour or ammonia-like odor, cloudy eyes, or a slimy surface, and keep it cold from purchase through preparation.

Kolyoz, often called chub mackerel, is a close relative of mackerel found in the Mediterranean and nearby waters. Its rich, oily flesh has a pronounced savoury flavour and stays tender when cooked; pan-frying gives it a crisp exterior, while grilling brings out a smoky edge. In Turkey and across the Mediterranean, it is commonly served as a main dish with lemon and salad, or alongside greens and other simple sides.
Kolyoz is high in protein and provides omega-3 fats, with no carbohydrates. For a lighter meal, bake or grill it rather than frying, and pair it with vegetables.
Very high
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
