What points should be paid attention to when breeding loach? Is there any good way?

As we all know. Misgurnus anguillicaudatus has tender meat, delicious taste, rich nutrition and high market value, and is known as "ginseng in water". With the improvement of people's living standards, the demand for loach is increasing. So, what should we pay attention to in loach farming? First of all, we should have a deep understanding of loach, including its living habits, feeding habits and so on. Misgurnus anguillicaudatus belongs to the bottom warm-water fish, which inhabits the bottom of rivers, rice fields and ditches. When the water temperature is too high or too low, it dives into the mud and floats to the surface when the weather changes dramatically or it is sick. Misgurnus anguillicaudatus has a special respiratory function. Besides breathing through gills and skin, it can also breathe through intestines. Its intestinal wall is very thin and densely covered with blood vessels. When the water is short of oxygen, it will swim to the surface and swallow air directly, exchange gas in the intestine, and then discharge waste gas from the anus, so it has strong adaptability to harsh environment.

First, build aquaculture ponds.

The loach pond should have sufficient water, fresh water and no pollution, which is convenient for water intake and drainage. The subsoil is neutral or slightly acidic clay. The area of adult loach culture pond should be 100 ~ 300m2, and the periphery of the pond must be 40cm above the water surface. The fence material is preferably cement board, brick, hard plastic board, etc.

Second, pool cleaning and disinfection and fry stocking

The waters where loach is cultured are cleaned and disinfected with quicklime and bleaching powder to eliminate wild fish and enemy damage. After drying to the bottom of the pond, dig a small pit around the pond, and clean the pond with quicklime for disinfection before stocking loach. Pour large pieces of quicklime into ash with water and sprinkle it while it is hot. The dosage is generally about 50 kilograms of quicklime per mu of water. Then fresh water is added, the water storage depth is 20-30cm, base fertilizer is piled on the sunny side of the loach pond, the fertilization amount is 30-40kg/mu, then the pond water is deepened to 40-50cm, and loach seeds can be released in a few days.

Four. Diet and feed

The loach is omnivorous. Small animals, plants, microorganisms and organic debris in the water are all his favorite foods. Fish meal, blood meal, animal viscera, wild fish, shrimp and crab meat, snail meat, earthworm, silkworm chrysalis powder, Tenebrio molitor and grain, rice bran, bean dregs, bean cake, vegetable cake, wheat cake, distiller's grains, soy bean dregs and vegetable leaves are all mud. However, under the condition of artificial breeding, animal bait should not be fed alone, and it is best to feed it together with animal and plant bait. Otherwise, Misgurnus anguillicaudatus is prone to gluttony and indigestion, with abnormal intestinal breathing and "flatulence" and death.

V topdressing and water quality management

Topdressing can promote the reproduction of plankton in water, make up for the shortcomings of malnutrition and uneven feeding of artificial bait, increase the immunity of loach on the one hand, and reduce the cost of bait on the other. Therefore, loach should be topdressed in time according to the water quality after it is planted in the pond. Make the water body always in a state of "fat, alive, tender and cool". The transparency of the pool water is 30 ~ 40 cm, and the water color is yellow-green. Top dressing can pile up fermented and decomposed organic fertilizer or sprinkle manure around the pond.

Daily management of intransitive verbs

Daily management includes patrolling the pond to check the water quality, watching the water color, observing the activities and feeding of loach. In addition, the loach has a strong escape ability, so it is necessary to check whether the escape prevention facilities are perfect and whether there is leakage on the pond ridge, especially in rainy days.

The above are some personal views on matters needing attention in loach breeding for your reference.
