Is Spanish mackerel a deep-sea fish
Spanish mackerel is not a deep-sea fish, but an offshore fish, belonging to warm pelagic fish, with sharp teeth, fast swimming speed and fierce temperament. Generally, Spanish mackerel live in groups in the waters near Bohai Bay.
Offshore is generally an area where the water level is below 500 meters. Deep-sea fish, belonging to more than ten families, are characterized by large mouths and eyes, and some parts of the human body have luminous bodies. Freshwater fish of the class teleosteichthys, common in the depths of the ocean, generally below 2000 ~ 9000 feet. Flashers are not only used to trap prey, but also to lure immediate family members. In the whole evolution process, deep-sea fish have produced this unique growth habit in order to integrate into the living environment with high working pressure, extremely cold and dark weather. The habitat of deep-sea fish is the most unique in the world. Because the market competition on the seabed is not as fierce as onshore or offshore, many initial populations are enough to survive to this day. The most important marine fish groups are deep-sea fish, viper and hairy mouth fish. According to the scientific research of the Department of Agriculture of Tokyo University, the protein content of deep-sea fish is the same as that of general seafood and freshwater fish, but the lipid is generally less, so deep-sea fish is a low-calorie and high-protein food. The essential amino acid composition of protein is basically the same as that of bonito, mackerel and tuna, and they are all completely protein.
Deep-sea fish generally need high concentration of water in their daily life, and their taste is not as delicious as that of offshore fish. Spanish mackerel, as a common freshwater fish near the sea, can cook all kinds of delicious food. Many of them rely on Spanish mackerel, which is common in big cities at sea, as a special food to attract tourists. It has been praised by many customers in different places and in the East and West. This is a special food for all ages in Xian Yi.
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.
Benthic fish are white from bottom to top, and if their bellies are white, they are also hidden. Although they sometimes dive deep into the seabed to hunt, they still stay in the upper and middle waters for a long time.
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.
4. Bite food.
There are four ways for fish to eat: swallowing, sucking and pecking. Spanish mackerel has sharp teeth, which shows that it mainly bites food. That is to say, when it meets its prey, it bites it first, tears it into pieces, and then swallows it into its stomach.
