Can small fry breed in wild ponds? What do you need to pay attention to in fish pond farming?

1 A few days before the fingerlings are stocked, add the pond water to a depth of 20 cm and apply quicklime.

Pond disinfection to prevent fish diseases.

2 before the stocking of fish fingerlings, should be reapplied basal fertilizer, generally per mu of water surface should be applied after fermentation of human, livestock, poultry mixed fertilizer 1000 kg to 1500 kg, fertilizer 30 kg to 40 kg, in order to cultivate a large number of plankton.

For fish to feed. 3 Fingerlings should be stocked in a way that is herbivorous.

Fish is the mainstay, supplemented by fertilizing and omnivorous fish, and the stocking quantity is considered according to the water source conditions, aeration equipment, fish fingerlings, large water and breeding technology.

Fish. 4 .Newly dug ponds for fish farming are generally muddy and turbid, which affects fish respiration and plankton reproduction.

Quicklime is sprinkled every 10-15 days, which has a good effect of sedimenting and clean water, and also plays a role in preventing fish diseases. The dosage is 20-30 kg of chemical water per mu of pond each time, and sprinkle the whole pond each time.

5 .Regularly disinfect and clean the fish body, bait table (field), tools, etc., to eliminate pathogens and improve the disease resistance of the fish body. Once fish disease is found, measures should be taken in time to treat the symptoms**, usually feed some leeks, garlic, onions, wild perilla, calamus, etc., can prevent and ** fish enteritis, rotten gills and parasites.

and other fish diseases. <>

Fish. 6 .It takes a long time to improve the ecological environment such as dissolved oxygen of fish in newly dug fish ponds, so morning and evening inspections should be strengthened and new water should be injected frequently.

Pond to do no weeds, no debris, no residual bait, etc., the early stage of aquaculture water environment is poor, the later fish carrying capacity is large, in the rainy or hot weather, easy to float head or even flood pond dead fish, should take measures to eliminate as soon as possible.

In order to remove toxic and harmful substances such as heavy metal salts that endanger the fish body, the pond must be soaked in water before stocking the fish fry, soaked for several days and then discharged, and repeated after exposure for a few days. 7-10 days before stocking fish fingerlings with quicklime thoroughly disinfected, generally dry pond per mu with 75 kg of quicklime slurry evenly sprinkled in the whole pool, or with water according to the water depth of 1 meter per mu with quicklime 150 kg of water sprinkling the whole pool.

Fish. Before the fry go down to the pond, the water depth is required to be about one meter, the water color is gray-white, and the general transparency is kept at about 30 cm; The water quality should not be too fertile, otherwise it will cause the death of the floating head of the fry. Fingerling stocking should be done:

Herbivorous fish are the mainstay, supplemented by fertilizing and omnivorous fish, and the fingerlings should generally be stocked in winter, and the size of the fry is required to reach more than centimeters, and the deeper water body should reach 20 centimeters.

Fish.

It can be reproduced, but it is necessary to pay attention to the time of rearing small seedlings, as well as the cleaning and disinfection of the pond before releasing the fry, as well as the selection of the quality specifications of the fingerlings, and according to the different types of fish, the stocking density has a reasonable control.

It is difficult to breed small fry in wild ponds, fish pond fish farming should first clean and disinfect some sludge in the fish pond, and then let the small fry slowly adapt to the new environment, feed them first and then put them into the fish pond, so that the survival rate of small fry is relatively high.

To be able to reproduce, fish pond fish farming should first keep the water in the fish pond clean and free of bacterial infection, and try to have live water in.

There will be fish in the fish pond without fry, which may be due to the fact that the pond is not cleaned, resulting in some of the eggs still in the pond, or they enter the water body with the help of birds and insects, so as to hatch into fish. Usually in order to avoid some harmful species to the fish pond, it is necessary to clean the pond first, and the pond must be cleaned thoroughly, splashed with quicklime or bleaching powder, and the fish can be released after a week or two. <

1. Seedling: Fish pond fish farming should first be put into the seedling, choose high-quality seedling, if it is a set of breeding, you need to prepare a variety of fish fry, such as grass carp, carp, silver carp, etc. Fry need to be disinfected before restocking to prevent it from being infected with insect diseases in the future.

Normally, a batch of fry will die after the fry are released, usually due to transportation.

2. Water transfer: Fish farming must be water, especially when high-density farming, food must be sufficient. Therefore, in order to fertilize the water for a certain period of time, bacillus and photosynthetic bacteria can be used to promote the reproduction of microorganisms, so that the fry have enough food and can also inhibit the growth of harmful bacteria.

3. Feeding: After the fry grow to a certain size, they need to eat feed. Usually choose ryegrass, but not too old, otherwise it will cause enteritis, and do not throw overnight grass, the day is not eaten need to be fished out at night, so as not to be eaten by fish the next day.

One acre of fish pond can be stocked with 400-840 fish fry. The reason why there is such a big difference is because the yield per mu pursued is different, and the way of stocking is also different. If the yield per mu is 700 catties, you need to put 400 fish fry, if the yield per mu is 1000 catties, you need to stockpile 560 fish, and if the yield per mu is 1500 catties, you need to stockpile 840 fish.

It should be noted that stocking fry must pay attention to collocation. <

1. Control the water temperature: the stocking fry should first control the water temperature, the fry are different from the adult fish, and they are not resistant to low temperatures, so the temperature is usually kept between 20-25, because it is transported, in order to avoid death after entering the pond, it is necessary to put the bag containing the fish into the pond water and soak it for 20-30 minutes.

2. Pay attention to density: although the fry are small, they will reduce their survival if they are raised more, and the economic benefits will be relatively low if they are raised, so it is necessary to pay attention to the feeding density. This is generally based on the size of the fish pond and the type of fry to choose, if the fry ***, the fish pond bait is sufficient, the feeding density can be larger.

3. Full food in the pond: before preparing to put the fry into the fish pond, it should be fed with egg yolk, after eating enough to go down to the pond can improve the ability to feed, but also conducive to adapting to the environment, it is easy to die if you go down the pond on an empty stomach.
