Origin
The scomber scombrus is a pelagic fish that lives in shoals in the sea near shorelines.
It has a length between 30 – 50 cm and can reach the age of 11 years.
The distribution area of the mackerel is in the coastal waters of North America, the North Sea, the Mediterranean Sea and the Black Sea.
Feeding Mackerel
They feed on plankton and the brood of other fish (e.g. herrings)
It also prefers with fish, crustaceans and mollusks.
Features Scrub
It has a full body, elongated, almost cylindrical, covered with small scales, a large head without scales, a large mouth, terminal, oblique, with poorly developed teeth. Behind the corners of the mouth has a triangular cut. The adipose eyelid does not cover the pupil of the eye.
The upperside of the forewings is greenish-blue with metallic glows. The sides are white with pinkish sheen. The belly is white. Ordinary weight 100g, exceptional 300-700g. ordinary length 17-30cm, exceptional 50cm.
For its caloric and mineral content, it is recommended in the diet of diabetics because it thins the blood, favoring circulation. 100 grams of scrubs contain 230 calories, 20 grams of cholesterol, 3000 mg of omega 3 acids and 250 mg of omega 6 acids, essential for heart health.
The scrub also contains vitamins A, C, D, E, K, but also B6 and B12. It is rich in magnesium and selenium, with important benefits in treating certain types of cancer. Besides these, scrubs at lunch also signify the intake of calcium, iron, phosphorus, potassium, zinc and sodium necessary for a healthy body.
Unlike other fish, scrubs do not have a swim bladder, which on the one hand helps them quickly change depth. The disadvantage of the lack of a bladder is that in order not to dive, you need to swim without interruption.
Blue mackerel is migratory, does not tolerate temperature variations. It lives in the southern regions of the sea, at deep. They gather in shoals, close to the N and N-V coasts of the sea, when the water reaches 8 degrees C, standing here if the temperature does not rise more than 16 degrees C, to fatten.
It approaches and moves away from these coasts relative to temperature and freshwater current. A small part of them stay all year round in the Black Sea, wintering here without reproducing. Most of them arrive in spring, around mid-May, from the Marmara Sea, completing the migration of stable cards from the Black Sea. When they come, they are very weak.
Experts believe that the diet with mackerel is 1,500 times more effective in preventing heart attacks, if there is a risk of relapse, than a drug treatment.
Reproduction Of Mackerel
In spring, during the breeding migration, the Danube scrubs gain a lot of weight, becoming rounder.
After spawning many of them die, and those that return to the sea are very weak.
Males reach sexual maturity at the age of 2 years, and females at 3-4 years, when they lay 10 000-150 000 eggs.Being semi-pelagic, the eggs float in the water and are driven by the current to the river mouth, where they hatch.
The chickens stay here all summer. Sometimes, when the waters of the Danube are high, the eggs are taken to puddles and floodplains. The chicks stay here and drain with the floodwaters, summer or fall.
