Ways to clear wild fish in ponds
It is known that fish ponds under artificial rearing have more or less wild fish. Their presence, to a certain extent, directly or indirectly affects the normal growth of the fish cultured, and brings about a certain degree of fishery production. Economic losses. Because they not only compete with the farmed fish for food, fighting for habitat space, but also consume a lot of oxygen. Therefore, removing trash fish is an important task. Wild fish come into the fish pond mainly in two ways: First, it enters with water (refers to juvenile fish or fertilized eggs that contain wild fish in the river water source); Second, it is mixed with some wild fish. The former is only required to add a suitable mesh sieve mesh filter at the inlet; the latter can use wild fish intolerant of the characteristics of low oxygen environment, the wild fish "trapped" dead fish out, and then, to put the fry. In addition, you can use the thorough clear pond disinfection method to kill wild fish. One week prior to the release of the fry, the pool water was drained, and then 10 cm of fresh water was added. The whole pool of 100-150 kg of lime per acre was evenly sprayed and the sediment of the pond was turned. In addition to killing wild fish, quicklime clear ponds can kill mollusks, parasite eggs, grasshoppers, and pathogens.
