Reasonable Fertilization Method for Fish Ponds



Introduction of reasonable fertilization method for fish ponds

You may use fertilizers directly and let them dissolve slowly. Water currents help to disperse the dissolved chemicals through the entire pond area. In small ponds one may use at least one fertilizing point per 1000 m2 of water area. In case of larger ponds , use 2-3 points per hectare, tentatively.


Reasonable Fertilization Method for Fish Ponds

1. Retain the fertile water

When the pond is cleared in winter, the pond where the fish are grown should try to retain the fertile water of the original pond, so that once the fish species are put into the fish pond, there will be richer feed for consumption.


2. Avoid using raw fertilizers

The fertilizers used in fish ponds must be fermented, and raw fertilizers must not be applied.


3. Fertilize according to the weather and water quality

The amount of fertilization depends on the weather and water quality. In spring and autumn, the weather is cool, the water temperature is low, the decomposition of organic matter is slow, the oxygen consumption is low, the fish's food intake is small, the activity ability is poor, and the dissolved oxygen in the water is also large. Vigorous, the amount of fertilization should be small and many times. The specific method should be considered according to the conditions of the fish pond itself and the activity of the fish observed in the early morning in the pond, as well as the weather.

When the water quality is fertile, the weather is sultry, and the air pressure is low, most of the fish float their heads. At this time, the application should be stopped or less applied; if the water quality is thin, the weather is cool, and the fish are active in the water, more fertilizer should be applied.

If human and animal manure is used as fertilizer, it must be fermented to prevent the rapid fermentation of immature fertilizer at high temperature and a large amount of oxygen consumption, causing pond fish to float and die due to lack of oxygen.


4. Sprinkling the whole pond

Fertilizer should avoid the food court, adopt the method of sprinkling the whole pond, and avoid pouring the whole bucket of fertilizer into the pond.


5. Sewage should be tested first

If domestic sewage is used, it must be tested first, and then used after it is determined to be non-toxic.


6. Fertilization of fingerling ponds

The fertilization of fingerling ponds is slightly different from that of adult fish. After clearing the pond, irrigate the pond with water, and then apply a certain amount of fertilizer, in order to cultivate the food that the small fry can eat. 

The timing of fertilization must be mastered, either sooner or later. If it is applied early, the individual plankton will grow too large and the fry cannot be swallowed; if applied late, the fry will not be able to eat, which will affect the growth.
