If there is not much green algae in the fish pond, it can be removed manually. Generally, the green algae can be fished out of the pond with a nylon net. The fished green algae can be used as feed for chickens, ducks and pigs. However, the proliferation of green algae is very fast, if the scale is relatively large, manual removal is time-consuming and laborious, and has little effect.
The reason why green algae grow in fish ponds is essentially because the water body is too fat, and the nitrogen, phosphorus, and potassium elements in the ponds are too high. In this case, drugs can be used for treatment. Usually, copper sulfate is used to soak water or add water with quicklime and bleaching powder, and sprinkle the whole pond once a month, which can not only eliminate green algae, but also disinfect and sterilize.
In fact, the best choice for dealing with green algae is shrimp. Shrimps have a strong ability to eat algae. Therefore, as long as black shell shrimps are raised in fish ponds, the problem of algae explosion can be solved. It should be noted that shrimp farming must not conflict with fish farming, because some fish will eat shrimp, some shrimp will eat fish eggs, so we must ensure that the two can get along well.
Most of the upright green algae can only be managed for a while. Although it is impossible to prevent the green algae from exploding forever, regular cleaning can greatly delay the time of algae explosion. Generally, fish ponds can be washed every two months in spring and autumn, and in the breeding season of green algae, that is, from May to September, they need to be washed once a month, so as to prevent algae explosion.
