CATDOLL : CATDOLL: What are the common deep-sea fish?

1. What are the common deep-sea fish?

Marine fish can be divided into deep-sea fish, offshore fish, and cold-water fish. For example, Norwegian salmon is a fish from the cold deep sea. There is less pollution in the deep sea, and most deep-sea fish grow naturally. Cold-water fish have a longer growth period, so they have more nutritional value.

The main species of deep-sea fish include tiger grouper, blue grouper, pink grouper, garry fish, maca fish, red fish, etc. There are more than ten kinds of deep-sea fish in restaurants. The most common one is grouper, which includes sesame grouper, sea tiger grouper, oily grouper, blue grouper, star grouper, etc. These fish are all grouper, but they look very different. Star grouper is the beauty among groupers, with fiery red scales and blue dots. The production is not large, so it is very precious, mostly 300 to 500 yuan per catty. Tiger grouper is dressed in white tiger skin stripes, with white and tender meat, and it tastes very delicious. There are also some grouper fish that look very ugly, such as the boss fish often mentioned in northern seafood restaurants, which has uneven body growth and is really unbearable to see. But this fish is not easy to move, crawling on the bottom of the water all day, and its eyes never roll around, which makes it look very calm, hence the name. In addition, the most common one is the flatmouth fish, which is also divided into left-mouth fish and turbot. This type of fish is flat and ugly, but when it swims in the water, it looks like a big butterfly with a beautiful posture. The most valuable fish in the seafood pool is the humphead wrasse, which is divided into large humphead wrasse and small humphead wrasse. The large humphead wrasse can weigh up to 8 or 9 kilograms; the small humphead wrasse has a very low yield and the price can be as high as 600-800 yuan per kilogram.

In seafood restaurants, you can also see small fish species from offshore, such as silver tuna, sandfish, yellow crucian carp, small yellow croaker and silver pomfret. These fish are produced in large quantities and are mostly frozen, so the price is very cheap. But their meat is white and delicate, and they are also very delicious. There are fewer yellow croakers now, but it is said that they can be caught in moderation, so we can eat real fresh yellow croakers again.

2. How to cook red grouper?

Grouper. It's good. I think it's just like stewing a big sea bass. Slowly stewed. It's very satisfying to eat with the soup. It's better to have a big pot. However, all groupers grow up eating corals on the seabed. They are toxins. []

3. How to breed grouper

Groupers like to live in the sea areas with rocky reefs, gravel and coral reefs near coastal islands. They usually do not live in groups. The water layer they live in rises and falls with the water temperature. In spring and summer, they are distributed in waters 10-30 meters deep, and in midsummer, they can also appear in waters 2-3 meters deep. In autumn and winter, when the water temperature drops, they swim to deeper waters of 40-80 meters. The suitable temperature range is 15-34℃, and the most suitable water temperature is 22-28℃. The suitable salt range is wide, and they can survive in seas with salinity above 10‰. They are carnivorous and ferocious fish, and they prey on benthic crustaceans, various small fish and cephalopods by surprise.

4. Which one is better, red snapper or grouper?

There are many types of grouper, such as the eastern star grouper, the cloud grouper, the blue melon seed grouper, and the hawksbill grouper. Anyway, each has its own attractions. Leopard gill perch, also known as red stripe, red grouper, and eastern star grouper. This is the authentic eastern star grouper. It was first called the eastern star grouper because it was abundant in the Dongsha Islands in the South my country Sea. It is bright red in color, with many blue spots on the head and body. The biggest feature is that there is a nearly complete blue ring around the eye socket. The maximum length is 120cm, and the maximum weight is: 23.6 kg. Because of the bright red color and festive feeling, the price is the most expensive among all the star groupers.

The skin of the grouper is smooth. When the fish is cooked, the skin cracks open and the white fish meat is exposed. You can pour oil on the fish or keep it as it is. The meat of the grouper is very delicious. The fish meat is chewy and slightly sweet. The gelatin of the fish skin is so sticky that you can't open your mouth.

6. What are the nutritional values ​​of grouper? What are the benefits to the human body?

Grouper is easy to digest and has a high absorption rate. 85%-90% of it meets the needs of the human body and helps the development of the human brain and vision. The meat of deep-sea grouper contains more than 20 trace elements and vitamins needed by the human body, and is high in protein, low in fat and low in cholesterol. The gelatinous layer of the fish skin contains a large amount of "hornbene", which is a special beauty element. The fish bones also contain precious "brain gold" ingredients that can activate brain cells, improve memory and delay brain aging.

Deep-sea grouper nourishes the liver and kidneys and prolongs life. It grows naturally in the deep sea below 100 meters, with little pollution and a long growth period of about several decades. Therefore, its meat is very chewy and its nutritional value is unmatched by other seafood.

The Eastern Grouper is a member of the Serranidae family. The Eastern Grouper is brightly colored and is well suited to being kept in a mixed tank with aggressive fish. Groupers are very aggressive predators and will eat any fish they can. They will also eat ornamental shrimp and other crustaceans. Unlike triggerfish, groupers swallow their prey whole rather than biting them. They will not harass fish they cannot swallow and can be kept with other species of grouper, but will fight with other groupers. Their diet includes various marine fish, squid, shellfish and shrimp. They need to be provided with some live food regularly, and sufficient nutrition will maintain their color.
