What kind of fish is mackerel
The mackerel is one of the important freshwater fish in China, a fish of the genus mackerel in the family Carpidae.
The mackerel is a very common freshwater fish in China, living mainly in the lower and middle waters, with a longer, larger body, a dorsal fin above the ventral fin, a flat exterior, and a greenish-gray body color, with a slightly darker back, and a grayish-white belly. Mainly distributed in China, Vietnam, Austria, Czech Republic, Malaysia and the United States, cyprinids are one of the four traditional freshwater fishes in China.
The mackerel is a carnivorous fish, taking the mollusks surviving underwater as its main food source, and especially likes the meat of snail nymphs, so it is also called snail master mackerel. Cyprinids have teeth, and the teeth are relatively sharp, can bite the hard shells of snail roach and other crustaceans, very voracious. It is now on the list of the world's protected animals.
How to raise mackerel is as follows:
1, pond construction
Farming mackerel should be chosen to have good water quality, adequate circulation of water, and water quality with the culture of standard conditions of the local culture. Setting up ponds also requires smooth drainage and irrigation, good ecological environment, no pollution and abundant feed resources.
The breeding area is about 20 acres, the water depth is about 2.3m, the thickness of the silt in the pond is best controlled at about 20cm, and it is also necessary to equip every ten acres with an oxygen machine and a feeder.
Winter needs to be drained from the pond, sunshine for about 20 days, injected 20cm of water for disinfection, sprinkle lime water, and so the water quality is completely dissolved can be, and then add water to release the fish to feed.
2, selection of fry breeding
In the selection of cyprinid fry, it is best to choose robust and proportionate, lively and active fry, the development of these fry and physical fitness are better and stronger. Note that if the fish species introduced from outside need to be tested and sterilized before they can be put into the pond for free-range cultivation.
You can use chlorine dioxide immersion for disinfection treatment, you can also use potassium permanganate about 20 mg, usually about 30 minutes can be disinfected, or with salt immersion for about 20 minutes can also be disinfected, and finally put when you can be put in the ratio of 8:2 can be put in the fish species.
3, the scientific proportion of bait
Mackerel generally to the waters of the edible water plants and active organisms for food, artificial breeding, we need to rationalize the use of scientific proportion of bait ingredients, to improve the conversion rate of the mackerel feed, do not because of a large number of food and lead to the accumulation of food in the bottom of the pond, resulting in decay and deterioration, thus affecting the quality of the water.
When building fish ponds, in order to reduce the cost of feeding, we can add a certain amount of fish grass powder, which can meet the special requirements of the mackerel on the mackerel fiber, but also conducive to the healthy and rapid growth of mackerel.
