2. Take the spawning pond and incubation pond as examples, with an area of 200m2, in which an incubation pond with a width of 1.8m and a depth of 0.35m is built in the middle of the pond. The pond should be kept clean, free from any pollution, and quiet at the same time, otherwise it will affect the spawning of the parent frog and the hatching of fertilized eggs. Different hatcheries are different in site construction.
After a hibernation, the temperature rose to above 16℃ in late March, and frogs began to feed. At this time, they should be fed with solid feed, so that frogs can quickly recover their physical strength and facilitate the next stage of reproduction and incubation.
If the breeding bases of Siwagou are all "back" ditches, there are some shortcomings such as inconvenient water intake and drainage, poor water circulation and inconvenient management, so it is planned to be transformed into a three-level "single ditch" to improve the effect.
Five rice planting density Rice and shading shed have their own advantages and disadvantages. Rice has additional benefits and good ecological benefits to the breeding environment. The disadvantage is that the density in the middle is too high, and no dead frogs can be seen, which is a great hidden danger. The benefit of shading shed is not high, but the frog situation is simple and intuitive, which is easy to manage and saves time and effort. Although most of them are mixed farming models of rice frogs, the purpose of rice cultivation is to shade frogs, not to increase income. Eat the harvested rice yourself, and don't worry about eating pesticides. The pattern of doubling the income of rice frogs is rare in frog farmers.
6 market conditions Compared with crayfish, the current frog market is rather chaotic. The price of the pond is very low in peak season, and 9 yuan/kg is normal. But in the restaurant, the average price is 25-30 yuan/kg, and the difference in the middle is earned by frog dealers, which makes frog farmers lose confidence and enthusiasm. So what needs to be done now is to stabilize the frog market and reassure frog farmers if the primary, secondary and tertiary industries can be combined. ?
