How many meters are deep-sea fish underwater?

Usually below 600 ~ 2700 meters (2000 ~ 9000 feet).

There are more than ten kinds of deep-sea fish, such as tiger grouper, green grouper, pink grouper, Jiali fish, Majia fish and safflower fish. The most common fish in restaurants are groupers, including sesame spots, sea tiger spots, oil spots, blue spots, oriental star spots, Antarctic orange snapper and Antarctic red shrimp. These fish belong to groupers, but they are far from each other in appearance.

The most precious fish in seafood pool belongs to Napoleon wrasse, which can be divided into big Napoleon wrasse and small Napoleon wrasse. The weight of big Napoleon wrasse can reach eight or nine catties. The yield of small Samui is extremely low, and the price can be as high as 600-800 yuan per catty.

In the seafood restaurant, you can also see small fish species close to seafood, such as marlin, sand tip fish, yellow crucian carp, small yellow croaker, silver pomfret and so on. These fish are abundant and mostly chilled, so the price is very cheap. But their meat is white and tender, and it tastes delicious. However, it is said that it can be caught in moderation, so that we can eat really fresh large yellow croaker again.
