1. It is best to build a pond and a loach in a well-watered place. It is best to use mud pools for cement. The trike should be used around the pond and the bottom of the pond should be tight. Before stocking, the pool should be filled with 30 centimeters of fertilizer and 30 centimeters of deep water. Ingress and egress of the water should be surrounded by wire mesh to prevent the mud from fleeing.
Second, the method of mud loach breeding loach natural reproduction is simple. After the spring, fix the fish pond, disinfect it with quicklime, and then inject new water. After the medicinal properties of the pool disappear, put the broodstock 1:2 into the pool, put about 300 grams per square meter, when the pool temperature rises to about 20°C It is necessary to place fish nests in the pool, and frequently check the cleaning of the dust and dirt on them to avoid affecting the adhesion of eggs when laying eggs. Muddy prefers spawning and laying eggs in thunderstorm days or when the water temperature suddenly rises. Mostly in the early morning, until the end of 10 o'clock in the morning, the spawning process takes 20-30 minutes. After spawning, fish nests with eggs should be promptly removed, and the other pool should be spawned to prevent the pro-fish from swallowing eggs. At the same time, make up new fish nests and continue spawning the unspawned broodstock.
The artificial propagation method of the loach is the same as that of the domestic fish. The culling season can be performed from late April to June. Before the oxytocin production, the selected male and female loach should be placed in two porcelain pots, and then the loach should be wrapped in gauze and the tail should be exposed. The oxytocic acid is injected again. The back muscles and abdominal cavity can be selected for injection. The species and dose are calculated in terms of females: 0.5-1 for carp pituitary or 2-3 for frog pituitary, 10-15 international units for chorionic gonadotropin, or similar (LRH-A) 5- 10 micrograms. Half of the dose was halved. After the parent injected the aphrodisiac drug, it began to heat in 6-8 hours in lukewarm water. It showed that the loach was invigorating the egg and then in vitro fertilization.
Muddy eggs are gray-yellow, slightly heavier fertilized eggs can normally hatch in the water temperature range of 20-30 °C, usually about 2 days to hatch fry, with a small container of static water, ground water change (2 times a day) hatching effect is good, 400-600 eggs per litre of water are preferred. The seedlings can be eaten within two days of hatching and need to eat some easily digestible nutrient-rich concentrates, preferably cooked egg yolks. As soon as the seedlings grow to about 1 cm, they can be fed into a breeding pond. By the end of the year, the average length of each tail can be about 2.5 grams, which will be used as a breeding species for the following year.
Third, feeding and management Mud Mu stocking capacity is about 150 kg, before clearing the pond to disinfect before planting, and then spread fertilizer mud about 30 centimeters, and apply enough basic fertilizer to cultivate food organisms, water surface to support algae, water lilies and other aquatic plants , Or use branches, grass, etc. to cover the surface of the water, shade, and feed peanuts, rice bran, bean dregs, distiller's grains, bran, etc. In order to increase the food organisms, several black light traps can be installed above the pool. At 7 o'clock, the overseas compatriots turned on the light at 5 o'clock on the morning and the insects were able to satisfy the needs of the loach for bait. Ponds should pay attention to constantly adding water or changing water, and it is strictly prohibited that pesticides and fertilizers flow into the pool. When the temperature rises to 25-28 °C in May-September, the muddy will dig into the mud to avoid the heat. At this time, it is necessary to pay attention to the irrigation of fresh water to increase the oxygen in the water and adjust the temperature of the water. If the water in the pool is brown or muddy, it is On the surface of the water, it shows that there is lack of oxygen in the water, it is necessary to stop fertilizing, and timely inject fresh water.
IV. Common diseases prevention and control Parasitic diseases: Common trichomonads, third-generation parasites, and other parasites that are attacked by parasites during the fry stage often float on the surface of the water. They are rapidly disturbed, or they turn around on the surface. 0.5 g/cubic water is used for treatment. Copper sulfate or 0.2 grams of ferrous sulfate Quanchiposa; or crystallized with five-tenths of the enemy trichlorfon (0.5 grams in a cubic meter of water) Quanchiposa.
Bubble disease: This disease is caused by excessive levels of oxygen or other gases in the salmon stage. The fish floated on the water, and a belly bubble appeared. Four to six kilograms of salt are sprayed per acre, which can also be flushed with fresh water or mud water.
Red fin disease: This disease is extremely harmful to fleas. After the loach is infected, the fins, abdominal skin, and anal area are congested and ulcerated. The caudal fins and pectoral fins are white and rot. You can dissolve 20 grams of furanes per cubic meter of water, bath for 15-20 minutes, or use 0.04% (drugs). The ratio of furanets to bait is 3 days for baits. It can also be sprinkled with furazolidone or bleach (1 gram per cubic meter of water or 1 gram of bleach).
V. Capture When the loach grows to 15-20 grams per tail, it can be picked up and listed. Generally, the water is released once every two months, but each time you do not catch too much, the catcher then discharges the water, generally about 1000 kg per mu.
