Detailed Explanation of Fish Farming Methods and Technical Points for Still-Water Fish Ponds

Anyone who has some understanding of rural areas is also fairly familiar with the many still-water fish ponds in the countryside. So how do farmers make use of these still-water fish ponds? How can fish be farmed in still-water fish ponds? What kinds of fish are suitable for farming there? Let us take a look together below.

1. Sludge Cleanup

There is quite a lot of sludge in still-water fish ponds, so if these ponds are to be put to use, the workload is also relatively large. After the large fish are sold each year, a thorough cleanup of the pond sludge is needed, so that stocking can continue the following year. If the excess sludge is not removed, a large number of the fry stocked the following year will die. Generally, the depth of sludge in a fish pond must not exceed 15 cm, and during normal farming, if there is too much sludge in the pond, it should also be drained and removed in time.

2. Pond Disinfection

Still-water fish ponds in rural areas are generally harvested only once a year, that is, before the Spring Festival each year, when price levels are relatively high and the fish taken from the pond can fetch a good price. At this time, all the still water in the pond needs to be drained, and after the sludge is cleaned out, disinfection and pond drying should be carried out. The disinfection period is generally about one week, and a common disinfection method is to add an appropriate amount of quicklime to the pond.

3. Filling with Water and Farming Fish

After disinfection is completed, clean, pollution-free water can be poured into the fish pond for farming. When farming fish in a still-water fish pond, the stocking density in the pond must be well controlled; the density must be neither too high nor too low. If the density is too high, there will not be enough oxygen in the pond, causing death from oxygen deprivation, while if the density is too low, of course, no money can be made. The most important thing is to observe changes in water quality and change the water in time.

4. Fish Species Selection

Farming fish in a still-water fish pond also has requirements for the species of fish. After all, the farming conditions do not meet the standard, and many fish species cannot be farmed, otherwise the losses will be very large. Therefore, before farming, it is necessary to choose fish species suitable for local still-water fish ponds. Generally, relatively common fish such as catfish, bighead carp, common carp, crucian carp, and grass carp can all be farmed. It is best to adopt mixed farming of multiple species, which can also help regulate water quality.

5. Points to Note

When farming fish in still-water fish ponds, there are also many points to note. Still-water fish ponds often experience oxygen deficiency, so when conditions permit, an oxygen-increasing agent or an oxygen supply machine can be added to the pond. Water quality in still-water fish ponds is also a relatively serious problem, so attention should be paid to changing the water frequently, and some aquatic plants such as duckweed should be planted in the pond, which can purify the water quality.

The above is all the content compiled by the editor for everyone about fish farming in still-water fish ponds. I believe everyone now has a rough understanding of how to farm fish in still-water fish ponds. In terms of rearing, still-water fish ponds are consistent with flowing-water farming, except that daily management is more troublesome and requires a great deal of patience.
