Among bass, there are both marine fish (such as sea bass) and freshwater farmed fish (such as California bass). 1. Sea bass: Mainly inhabits the junction of salty and fresh water in estuaries. The main production areas are the Sea of ??Japan, Yellow Sea and Bohai Sea in Asia. 2. Matsue Bass: Mainly distributed in the southern bay of Japan, the west coast of the Korean Peninsula, and the northeastern coastal areas of China. It enters freshwater areas for fattening in April and migrates to near the estuary from November to December. 3. California bass: Mainly inhabiting shallow waters of warm lakes and ponds, it is an important freshwater cultured fish species in China.

1. Is seabass a sea fish?

There are many varieties of seabass, including sea bass, Songjiang seabass, California seabass, river bass, etc., among which there are seawater fish (such as seabass) , and freshwater farmed fish (such as California bass).

1. Sea bass

(1) Sea bass mainly inhabits the junction of salty and fresh water in estuaries, and can also live in fresh water.

(2) At present, the main production areas of sea bass are the Sea of ??Japan, Yellow Sea, and Bohai Sea in Asia, as well as the west coast of the United States, the Peruvian fisheries in South America, and the British North Sea fisheries.

(3) In my country, the main producing areas of sea bass include Qingdao, Shidao, Qinhuangdao and Zhoushan Islands, and the fishing season is spring and autumn every year, with October to November being the peak fishing season. .

2. Songjiang perch

Songjiang perch is mainly distributed in the southern bay of Japan, the west coast of the Korean Peninsula, the northeastern sea area of ????China's coast, and the corresponding downstream waters of rivers. It is transported from the Yangtze River around April every year. They enter freshwater areas for fattening, wait until around December to January of the next year, and then migrate to estuaries or offshore waters.

3. California bass

(1) California bass (largemouth bass) mainly inhabits lakes with warm water temperatures and shallow waters of ponds.

(2) California bass originates from the United States and Canada. It has now become an important freshwater cultured fish species in China, with Guangdong Province accounting for about 75% of the country’s cultured fish.

4. Perch

(1) Perch lives in rivers and lakes with dense vegetation. It is mainly divided into two groups. One of the groups lives in shallow water areas along the coast, mainly as It feeds on invertebrates and is smaller in size, while the other population lives in deep water areas and feeds mainly on small fish and is larger in size.

(2) Perch is widely distributed throughout Europe and Siberia. In my country, it is mainly distributed in the Irtysh River and Ulungu River systems in Xinjiang.

2. Characteristics of Bass

1. Bass has a long body and flat sides, a medium-sized head, a large mouth, the lower jaw is longer than the upper jaw, and the upper jaw reaches below the back edge of the eye. The back is slightly raised and is blue-gray in color. The abdomen is round and blunt, and is silvery white like the sides of the body. There are black spots on the upper side of the body and dorsal fin, but these gradually decrease with age.

2. The bass is covered with tiny scales and has two dorsal fins. The first dorsal fin is harder (12 hard spines) and is almost attached to the back, but is relatively small. The second dorsal fin is smaller. Soft (1 hard spine and 11-13 soft fins), but relatively large. The tail fin and pectoral fin are relatively short, so the bass appears very rounded overall.
