2. Eastern star spot.

3. Spotted grouper.

5. Red melon seed spots.

6. Oblique grouper.

7. Su rat spot.

Grouper classification grades: tiger grouper, sea green grouper, pearl grouper, east star grouper, sesame grouper, mouse grouper.

1. Tiger grouper.

It belongs to the cheaper level, this kind of grouper breeds more places, when choosing to buy, pay attention to check the integrity of the fish, whether the color of the fish body is natural and uniform, and whether there are large and small white spots on the body surface of the fish.

2. Sea blue spots.

It belongs to the most inexpensive grade, and it is often sold in whole pieces on the market, which can be used for stewing soup and frying.

3. Pearl dragon barge.

It belongs to the most expensive class.

4. Eastern star grouper.

It belongs to the most expensive grade, this grouper is mostly farmed on the market, and there are few wild ones.

5. Sesame spots.

It is a high-end ingredient, and most of the best on the market are farmed, and there are fewer wild ones.

6. Mouse spots.

Grouper is a very high-end ingredient, the cost of breeding is high, and wild rat groupers are very rare.

Grouper farming methods

1. Seedling. Go to the regular farm to choose smooth lines, swim as much as possible, scales have obvious damage, the best luster of the fry, can be used cage farming, has the advantages of high breeding density, easy management, and high natural benefits.

2. Breeding conditions.

Choose the sea surface without wind, the waves are not big, there is no storm to disturb, the sand quality of the seabed is good, the reef, the coral reef is more in the sea area to breed grouper, the sea water transparency is in centimeters, and the traffic should also be convenient, which is convenient for the transportation of seedlings and feed.

3. Breeding density.

The culture density of grouper is related to the seawater flow rate, and the density can be increased appropriately in the sea area with fast flow rate. The general length is 3 meters, the width is 3 meters, and the depth of the cage is 3 meters, which can raise 2,500 fry.

Grouper. The nutritional value is extremely high, and some groupers will taste even better, so what species of grouper are delicious?

6. Sea red spots.

7. Tiger grouper.

8. Numbles. 9. Money spots.

10. Cedar spots.

11. Su rat spot.

12. Red melon seed spots.

What is the difference between red grouper, mackerel and tiger grouper? Today I know it.

Grouper, commonly known as grouper and fish in Guangdong, and commonly known as bighead carp and national fish in Fujian and Zhejiang. There are many kinds of grouper, there are about 100 kinds of groupers in the world, and more than 30 species have been recorded along the coast of China.

Thanks for adopting!

Groupers can be divided into many species: blue grouper (blue grouper) with spotted grouper

Oblique grouper, East star grouper, West star grouper, Tai star spot, leopard star grouper, mouse grouper, tiger grouper, green grouper, hemp spot, money grouper, cedar grouper, Su mouse grouper, red melon seed grouper, dragon grouper (giant grouper).

The types of grouper are as follows:1. Tiger grouper.

2. Eastern star spot.

3. Spotted grouper.

4. Red-spotted grouper.

5. Red melon seed spots.

6. Oblique grouper.

7. Su rat spot.

Grouper species are a bit grouper, red spotted grouper, blue grouper, oblique grouper.

1. Spotted grouper

The dorsal fin has 8-11 spines, no dark spots at the base, 5 inconspicuous transverse bands on the side of the body, and scattered spots on the side of the body and on each fin. It is a tropical middle and lower pelagic fish, which likes to inhabit the bottom sea area of rocky reefs and is a valuable fish in the South China Sea. Fierce in nature, carnivorous, likes to eat fish, shrimp, crabs, and cannibalism when hungry.

2. Red-spotted grouper
