Spanish mackerel is one of the common fish in China and belongs to marine fish. The distinction of marine fish can be made according to the depth of the sea where they are distributed. Deep-sea fish are distributed in the deep sea, while shallow-sea fish are distributed in the shallow sea. According to this standard, Spanish mackerel can be divided into shallow water fish, usually living in shallow water and rarely going to deep water. The water pressure in the deep sea is relatively high, and Spanish mackerel cannot adapt to its environment.
Specifically, Spanish mackerel is generally distributed in the water with a water depth of less than 100 m, and some Spanish mackerel are distributed in places with a water depth of less than 50 m. Spanish mackerel is distributed in the middle and upper layers of seawater, and most of the time it moves in these two water layers, generally not in the bottom. Only in winter, Spanish mackerel will spend the winter in deeper places because of the lower water temperature.
At this time, although it is distributed in the depth, the overall depth will not exceed150m. When the water temperature starts to rise in spring, they will move to shallow water.
The habits of Spanish mackerel
1, which belongs to pelagic fish and mainly swims in the middle of water. Its ivory belly and blue-green back are its camouflage colors. Most pelagic fish in the ocean are of this color, because when the prey in the air, such as birds, look down, the blue-green fish back is consistent with the color of the sea water, so it is difficult to be found.
2, feeding on small fish, like chasing live food, not interested in static and rotten food.
3. Keep swimming. Unlike benthic fish, Spanish mackerel doesn't hide in caves on rocks, waiting for a small fish to come and suddenly open its mouth and swallow it. It must keep swimming, because once it stops swimming, it will lack oxygen. This is similar to a shark. Therefore, Spanish mackerel prefers flowing waters, so it can get enough oxygen without swimming hard.
