Cement pond breeding muddy quick effect

There is less investment in feeding muddy, quicker results, and higher returns. The following describes how to build a mud pool for breeding mud louse. Interested ones can try it.

First, build the pool. Fish ponds can be made of bricks and stones, and the size and shape of the fish ponds can be determined by themselves. Pool depth requires one meter or more. The entrance and exit of the fish pond should be surrounded by wire mesh or plastic net. The bottom of the pond should be inclined slightly toward the outlet for drainage and fishing. After the tanks are built, they are leveled with cement and put into a clay slurry of 16-20 cm after being solidified, and 35-50 cm of fresh water is poured into the tanks. The edge of the pool must be more than 50 cm above the water's surface, because the mud is active to prevent fleeing.

Second, selection. The annual “summer solstice” is the best time for breeding. The seedlings can be purchased on the market or artificially propagated and captured. The amount of seed can be 0.5-0.75 kg per square meter. To choose a strong, harmless, uniform size of the seedlings, and with a ratio of a female and male. The identification method of male and female carp: you can see its appearance, male and female seedling tip, narrow and long pectoral fins, body length and tail thickness as the tail tip upturned, fin base with a thin slice of bone; and female pods oval head, rough body The tail is thin, the pectoral fins are wide and short, and the ends are rounded. The breeding season of the loach is from May to August each year, with 7000-10000 eggs per end. If artificial oxytocin production is used, 2-3 frog pituitaries are injected into each loach. At a water temperature of 20-25°C, eggs can be laid after 24 hours. Brown leaves can be used as an egg attachment tool. The fertilized eggs emerged in about 2 days. One day after emergence, the eggs were fed every 100,000 fry, and they were ground into a sauce after grinding. Change the water twice a day, and put it into the fish pond 10 days later. The hatched seedlings should be single-cultivated and can be used as the second-year-old fish species.

Third, management. Loach is omnivorous fish, fish meal, bean cake, bean dregs, rice bran, bran, cow dung or fly maggots can be used as bait.

In the feeding process, the amount of mud loach is generally determined according to the feeding conditions. It is sufficient to feed the feed 4 times a day, and it should be dispersed along the pool when spreading the bait. Prevent squid from snatching the blunder. Appropriate supplements can also be applied to organic fertilizers, but when fertilizing, do not overdo it too often. The water quality of the pool must maintain a certain degree of freshness. If the pool water appears dark brown or dark brown, the muddy water will continue to float to the surface to swallow the air, indicating that the water quality is aging. Fertilization and feeding should be stopped. The water must be changed in time, and the water is changed every month. 3 times.
