How can we improve the water quality of fish ponds?

Fish farming in fish ponds has high economic benefits. In order to ensure the growth of fish, farmers must pay attention to water quality management to avoid causing fish illness or death. So how can we maintain good water quality in fish ponds? Let’s take a look with the editor below.

1. Feed properly

Develop a feeding plan based on the fish's growth stage, number, weather, and water quality. Avoid overfeeding to reduce feed residue and fish feces accumulation. Choosing easily digestible, nutritious feed will help fish absorb nutrients better and reduce the production of excrement.

2. Change water regularly

Change the water in time according to the water quality of the fish pond. It is generally required to add fresh water once every 7 to 10 days, with the amount of water added each time being 20 to 30 cm; change the water once every 15 to 20 days, and you can use the method of adding and draining at the same time. It is best to drain the bottom water. Make sure the new water is clean and unpolluted, and the temperature difference should not be too large to avoid causing stress to the fish.

3. Control algae growth

Clean algae from your fish pond regularly to prevent it from overgrowing and consuming oxygen in the water. Biological methods such as releasing algae-eating fish can be used to inhibit the reproduction of algae.

4. Reasonable use of oxygen enrichment equipment

During the main growing season of fish, extend the operation time of the aerator to ensure sufficient dissolved oxygen content in the fish pond. Check dissolved oxygen levels regularly to ensure they are within the appropriate range.

5. Strengthen daily management

Patrol the pond every day to observe changes in water quality, fish growth and activity. Record various data during the breeding process in detail, such as feeding amount, water quality indicators, fish growth, etc., in order to summarize experience and lessons. Regularly clean the silt and leftover bait at the bottom of the fish pond to keep the water clean.

6. Reasonable use of quicklime

Regular use of quicklime in aquaculture ponds can play an important role in purifying water quality, adjusting pH value, improving the aquaculture environment and preventing fish diseases. It is usually used once every 15 days, with a dosage of 10 to 15 kg per mu.

The above is an introduction to how to maintain good water quality for fish ponds. If you want to maintain good water quality for fish ponds, you can also plant aquatic plants in moderation, such as water plants, water hyacinth , etc., which can effectively improve and maintain the water quality of the fish pond and provide a good growth environment for fish.
