What do you need to pay attention to when using aquaculture in aquaculture? Recently, some netizens wrote to Xiaobian that when they are breeding aquatic products, can they use river water culture? The answer is that it can be farmed in river water, but it is not used casually. The use of river water in aquaculture is also required. For example, the use of contaminated river water, or the disease of ponds and the discharge of water after spraying the pesticides, etc., cannot be used. Today, Xiaobian will specifically talk about the precautions for using aquaculture in aquaculture. Let’s take a look at it with Xiaobian.
1. First of all, first look at whether there are industrial manufacturers in the upstream and downstream of the river. Because there are industrial manufacturers downstream of the river, industrial waste will be discharged to the river. It is treated, but it will also cause some pollution. It is not recommended to have a farm near an industrial production plant.
2. Secondly, attention should be paid to the growth of surrounding farmland. If the farmland is in the stage of prevention or treatment of certain pests and diseases, pesticides will be used, and pesticide residues will flow into the river along with irrigation, so it is not recommended to be near farmland. Set up a farm.
3, pumping and drainage should try to be in the rivers of two different river basins.
4, the farm should set up a reservoir, requiring the reservoir to account for about one-tenth of the total aquaculture area. At the same time, after inputting the river water, spray 2-5ppm of bleaching powder on the whole pool and stir evenly. At the same time, turn on the aeration pump, turn off after about 24 hours, wait for the reservoir to precipitate and volatilize the gas for 3-5 days. Breeding.
5. Finally, it is necessary to observe whether there are farmers in the surrounding area, because some farmers have diseases in the ponds and if they are used after spraying the medicines, if they are used, they may cause cross-infection of the fish in their own ponds and cause diseases.
