Spanish mackerel is a shallow sea fish, not a deep sea fish. They live in the shallow sea, and the water pressure in the deep sea is so high that Spanish mackerel can't adapt to this environment. Spanish mackerel usually lives in a relatively shallow sea area, not more than 100 meters, and some Spanish mackerel even live in the sea less than 50 meters deep. They like to move in the middle and upper layers of the water, and only when winter comes will they go to the bottom for the winter. In winter, their distribution depth is generally not more than 150 meters, which is not particularly deep.
1. Is Spanish mackerel a deep-sea fish or a shallow-sea fish
? Spanish mackerel is one of the common fish in China and belongs to marine fish. Marine fish can be distinguished according to the depth of the sea area where they are distributed. Those distributed in the deep sea are deep-sea fish, and those distributed in the shallow sea are shallow-sea fish. According to this standard, Spanish mackerel can be divided into shallow sea fish, which live in relatively shallow waters and seldom go to deep water areas. The water pressure in the deep sea is relatively high, and the Spanish mackerel can not adapt to the environment.
Specifically, the water depth of Spanish mackerel is generally not more than 100 meters, while some Spanish mackerel are distributed at a depth of no more than 50 meters. Spanish mackerel is distributed in the middle and upper layers of the sea area, and most of the time it is active in these two layers, generally not to the bottom. Only when winter comes, Spanish mackerel will spend the winter in a deeper place because of the decrease of water temperature. At this time, although they are distributed in deeper places, the overall depth will not exceed 150 meters, and when the water temperature begins to rise in spring, they will move to shallower places. As mentioned
above, in the season when the water temperature is suitable, the distribution depth of Spanish mackerel generally does not exceed 100 meters, and there are many Spanish mackerel whose distribution depth does not exceed 50 meters. Other Spanish mackerel live near the estuary and are distributed in shallower waters. When the water temperature drops sharply, that is, when winter comes, Spanish mackerel will go to a slightly deeper sea area for winter, but generally it will not exceed 150 meters, mostly concentrated in 80-150 meters. After the water temperature rises, the depth of the water in which the Spanish mackerel lives will change again and move to a shallower place.
