How to remove duckweed in the pond?

1. If the number of duckweed in the fish pond is small, you can salvage it by yourself with some fishing tools.

2. If the duckweed in the fish pond is serious, you can go to the store to buy some drugs to remove it.

3. Adopt ecological management, cultivate some bream, grass carp or crucian carp in the fish pond, let the fish eat, and remove the duckweed.

4. Duckweed usually overwinters under the stems and leaves of Alternanthera philoxeroides, and its overwintering survival rate is high. In winter, the water peanuts on both sides of the river can be fished out, which will destroy the overwintering environment of duckweed and reduce the number of duckweed overwintering, so as to reduce the harm of duckweed in the next year.

Matters needing attention for duckweed feeding fish:

1. Don't feed duckweed and cover the water surface of all fish ponds. When feeding duckweed in a fish pond, it is best to enclose a water surface with bamboo poles in one corner of the fish pond as a feeding ground, and the area of the feeding ground is generally not more than 1/5 of the pond water area. Put duckweed in the feeding area for fish to eat. If there are too many duckweeds in the fish pond and there is no special feeding place, so that duckweeds float and cover all the water surface, it will affect the photosynthesis of algae in the water body and cause hypoxia in the pool water.

2. Don't feed duckweed in large quantities in hot or thunderstorm days. When the weather is sultry or there is a thunderstorm, the dissolved oxygen in the pool water will drop. If duckweed is fed in large quantities at this time, the dissolved oxygen in the pond water will be further reduced, which will easily lead to the death of fish in the pond.

3. Don't feed duckweed in the evening or at night. It is best to feed duckweed in sunny morning, and avoid feeding in the evening or at night. Duckweed thrown into fish ponds in the evening or at night, on the one hand, will consume a lot of dissolved oxygen in the water by its own respiration, on the other hand, after fish are full at night, it will also increase the respiratory oxygen consumption, both of which will lead to hypoxia in the pool water.

4. You can't feed the polluted duckweed. The duckweed fed to the fish pond should be clean and pollution-free, and it is advisable to eat fish within 2 ~ 3 hours. Otherwise, the polluted duckweed will be put into the fish pond. After eating the fish, the growth of the fish will be slightly affected, and if it is serious, the fish will die.
