Harm of Rotifer to Adult Fish and Its Control

In recent years, when carrying out technical services, the author found that rotifers were rampant in adult fish ponds in some areas, which had a lot of impact on farmers, especially in some old areas or places farmed with sewage. This phenomenon is particularly serious and should be paid enough attention to.

Harm of rotifer to adult fish

The harm of rotifer to adult fish is mainly as follows: rotifer has a super reproductive speed, and it will form a dominant population in a short time, eat most of the algae, reduce photosynthesis, weaken oxygen production capacity, and consume a lot of oxygen at the same time. As a result, it is very easy to cause anoxia and even death of fish; second, it needs to be killed frequently, resulting in an increase in culture costs. Third, due to the difficulty of thorough removal in the pond, the pond water is often anoxic, affecting the growth of fish; fourth, rotifer decay and decomposition after death will also corrupt the water quality, affect the growth of fish, and even cause disease, resulting in fish death.
