What are the breeding conditions of Pseudosciaena crocea?
When breeding, you can choose the breeding pond, but the pond should be set close to the water source and convenient for irrigation and drainage, and the water should be changed every day, and the area and breeding scale of the pond should be determined according to the number and density of breeding, and the depth of the pond should be 2 to 3 meters.
Put some high-quality water sources in the aquaculture pond, and the transparency of these water sources should be more than half a meter, the water temperature should be guaranteed to be between eight degrees and 28 degrees, and the dissolved oxygen should be guaranteed to be more than five millimeters per liter. And before stocking fry, the fish culture pond should be completely disinfected to prevent some harmful substances, bacteria and microorganisms in the pond from endangering the health of fry.
Can Pseudosciaena crocea be cultured in fresh water?
The body structure of Pseudosciaena crocea is only suitable for seawater survival, and freshwater culture has not been successful.
Most farmed Pseudosciaena crocea build canals in coastal cities to introduce seawater or mix seawater.
What's the difference between cultured and wild yellow croaker?
1, the difference in appearance:
Wild yellow croaker has a yellower body color, a brighter mouth, a slimmer body and a smaller belly. Because of the living environment, the mouth and eyes of wild yellow croaker will appear larger, the scales will be thick, and the meat quality will be relatively closely arranged. It tastes "chewy" and tastes delicious.
Artificial cultured Pseudosciaena crocea is relatively leisurely living in cages, lacking exercise, with a fat body, a bulging belly, dark yellow or gray skin color and light lips.
2, the difference of meat taste:
The fins of wild Pseudosciaena crocea are generally clean and complete, and the fins are long. Moreover, when fishing from the sea, the swim bladder is killed due to the explosion of air pressure, and there is little painful struggle. The taste is good, and the scales and fins on the body will not leave traces of congestion. Those fins look a little red and broken, and the fins are short;
Artificial cultured Pseudosciaena crocea is usually kept in cages, and it is easy to be injured when swimming in a narrow space. At present, some deep-sea cultured Pseudosciaena crocea are similar to wild Pseudosciaena crocea in appearance, but the meat tastes a little soft and the taste is not as pure as wild Pseudosciaena crocea.
3. Yellow croaker is divided into large yellow croaker and small yellow croaker, which are one of the four major marine species in China. Pseudosciaena crocea is also called Daxian, Jinlong, Huanggua Fish, Red Melon, Huang Jinlong, Osmanthus crocea, King Fish and Rhubarb. Small yellow croaker is also called Plum, Plum Fish, Xiaowang Fish, Xiaoxian, Koharu Fish, Small Yellow Croaker, Thick Scaled Fish and Flower Fish. They all belong to the fish class, the grouper family.
