Feed shrimp 80% full body and save money
According to the practice, if we feed less and more meals and stop feeding 1-2 tons of feed every 7-10 days, we can not only make the shrimp grow healthily and gain weight normally, but also save the feed cost of raising shrimp.
Feed less and raise shrimp more often. Feeding less and eating more refers to changing the original 4 meals a day into 5-6 meals. Although the number of daily feeding has increased, the amount of feed each time has been relatively reduced, and the feed that used to be eaten in 1.5 hours can now be eaten up in 1 hour. The advantages are as follows: first, the retention time of feed in water is shortened, which can reduce the loss and pollution to the water. Because the feed is soaked in water for a long time, it is easy to become loose, and the nutrition is lost in the water, which will cause water pollution and feed waste. The second is to keep the shrimp at 7-80% full, and the shrimp will maintain a strong appetite, so that the vitality of the shrimp will be good, and it will grow fast.
Properly cut off the method of raising shrimp. Practice has proved that the proper suspension of 1 meal every 7 to 10 days will not affect the growth of shrimp, but will have the following benefits: first, shrimp can fully eat zooplankton and phytoplankton in water, which, to a certain extent, shrimp can purify the water by itself. Second, before feeding drugs or nutritious baits, stop feeding for 1 or 2 tons and then mix them to feed, which can improve the absorption rate of shrimp and enhance the efficacy and nutrition. The third is to stop feeding properly, while not affecting the growth rate of shrimp, raising a crop of shrimp can also save a considerable amount of feed money, so as to effectively reduce the cost of raising shrimp.

Breeding method of yellow edge box tortoise
To raise yellow edge box turtles, it is best to buy turtles from April to August every year, during which the number of turtles is large, the price is low, and it is suitable for domestication and breeding. During the period from January to March, the tortoise is hibernating or about to hibernate, so it is difficult to observe the turtle's activity, food, feces and so on. It is difficult to grasp the survival rate of turtles. The source of adult yellow box turtles mainly depends on the acquisition of wild turtles. Wild turtles are thin, timid and have many wrinkled skin on their limbs. Turtles can be selected from the appearance and feces of the turtles. Healthy turtles have bright eyes.

What should we pay attention to when catching pond fish in autumn?
First, pay attention to the weather. In autumn, the fishing must be carried out before and after the dawn of sunny days, cool climate and non-floating head of the pond fish, which has the least impact on the fish in the pond and can supply the fresh fish caught in the morning market in time. Haze, muggy weather is not suitable for net fishing, so as not to cause a large number of dead fish. In addition, it is not suitable to catch fish in ponds when they have floating heads or fish diseases. Second, feed should be restricted before arrest. After the fish is full, the oxygen consumption increases, and it will jump and flee when pulling the net, which is easy to cause casualties. Therefore, the catch was made by pulling the net.
