Fish ponds are prone to insects after adding water, how to effectively kill insects?

Pay attention to grasp the timing of adding water to the fish pond, should grasp the time of adding water, add water according to the weather changes, temperature, water quality conditions flexible mastery: breeding ordinary fish, generally every 7 days or so to the pond to add water 1 time. You can put some disinfectants against insects in the water, to ensure that there is no damage to the fish, and some fish can be added according to the proportion to eat insects, and some can be properly raised.

In the practice of aquaculture, according to the change of seasons in a timely manner to adjust the water level, control the water temperature, such as the spring temperature is low, the water level of the fish pond should be shallow, which is conducive to improving the pond water temperature, but also conducive to fish feeding, growth and the cultivation of natural bait organisms. If you want to make the water in the fish pond reach the environment where the fish grow, you must first replace the old water in the fish pond, then disinfect, and then change the water, so that the water quality can be purified, and it is not easy to grow insects.

There are these small insects, indicating that the water quality in this pond is too fat, so that although the fish grow relatively fast, but the quality of the fish is not good, the taste is not good, you can replace the water in the fish pond, let the fresh water into the pool, replace the fertilizer water, the small worms will disappear. Algae.

Bacteria, protozoa.

Organic crumbs. The richer algae, bacteria, protozoa, and organic detritus, the more zooplankton will grow. Therefore, in some ponds with relatively fertile bottoms and water bodies, and rich in bacteria and organic debris (bottom feed residues), it is inevitable that there will be many of these zooplankton.

It should be fine to disinfect with lime, but the amount of disinfection should be grasped before adding water, splash the whole pond with bleaching powder, quicklime.

It is also possible to inject water after a few days of precipitation, but the subject's problem is that there are worms after water injection, which can also be remedied, and trichlorfon can be used.

It is best to clean up the silt in the fish pond, replace it with clean water, and install an aeration pump to see the size of the fish pond, and then regularly disinfect and add water to the fish pond to avoid necrosis of water quality.

Before adding water to the fish pond, splash the whole pond with bleaching powder, quicklime can also be used, and then fill the water after a few days of precipitation. After water injection, this can also be remedied, you can use trichlorfon, the whole pond is sprinkled, solid trichlorfon can effectively kill most of the insects, some fish pathogenic bacteria, but the best is to splash bleaching powder before water injection, dry the bottom of the pond for more than half a month.

First of all, we have to disinfect the fish pond, after the fish are fished out, melt with some quicklime and water, and sprinkle it into the pond while it is hot, which can not only eliminate the harmful organisms in the fish pond, but also avoid the death of the fish fry.

You can use trichlorfon to splash the whole pond, solid trichlorfon can effectively kill most of the insects, it is best to clean up the silt in the fish pond and replace it with clean water.

First of all, we can add some appropriate fry in the fish pond, which can have the effect of eating insects, and secondly, we can add some insecticides that do not harm the fish in the fish pond, which can effectively kill insects.

Hello dear, pond insecticide and disinfection call for fish growth is fast after destruction. After pond insecticide and disinfection, the speed of fish growth is related to a variety of factors, including fish species, water quality, feed, water temperature, etc. In general, the water after disinfection is cleaner, which is conducive to the growth and health of fish Sakura.

However, if the concentration of disinfectant used is too high or used incorrectly, it can cause harm to the fish, affecting their growth rate and health. Therefore, it is recommended that when disinfecting the pond, choose the appropriate disinfectant and concentration, use it according to the instructions, and carry out adequate cleaning and water quality adjustment after disinfection to ensure the health and growth of the fish. At the same time, the water quality and fish body condition should be regularly monitored to identify and solve problems in time to ensure the healthy growth of fish in the pond.

Hello dear, I am happy to serve you<>

The fish pond is fertilized for a few days after killing insects, depending on the size of the fish pond, the number of insects, the type of agent used and the amount of agent. Generally speaking, if the fish pond is smaller, the number of insects is smaller, and fewer pesticides are used, then after killing the insects, the fertilizer water can return to normal within 1-3 days. If the fish pond is larger, the number of insects is higher, and more pesticides are used, then it may take 5-7 days for the fertilizer to return to normal after killing the insects.

In addition, it should be noted that before the fertilizer water returns to normal, the water quality should be checked at the banquet period to ensure that the water quality meets the requirements of fish growth.

Fish pond insecticidal timing 1, the first insecticidal timing from mid to late March to around Qingming, the water temperature is 18-20, and the first insecticidal can be carried out for 3 days on a sunny day. For the first insecticide, it is recommended to use trichlorfon (prohibited for scaleless fish, shrimp and crabs such as mandarin fish, pomfret pomfret and California perch, forktail and largemouth catfish) or phosphine copper sulfate. 2. If the timing of the second insecticide is to kill the ring worm, the water temperature is less than 20 degrees, and the second insecticide is carried out at an interval of 7 days after the first insecticide; When the water temperature is higher than 22, the second insecticide should be carried out at an interval of 3 days; If it is a wheel insect killer, the second insecticide is carried out at an interval of one day (the ring worm can hatch in 3 days when the water temperature is 22 26; The reproduction cycle of the wheel worm is only 24 hours).

For the second insecticide, it is recommended to use powdered Sophora sophora. The day after the second insecticide, the whole pool was disinfected with chlorine dioxide tablets to prevent secondary bacterial infection.

Improve the environment after winter fishing or before the arrival of the spring rainy season with quicklime disinfection, the amount of 25 40 grams of cubic meters, at this time less medicine, can save investment. Appearance.

After disinfection, use conventional insecticides to kill insects once 90% crystal trichlorfon grams cubic meters or new insecticides, and the dosage is as indicated.

Before releasing the fish, the medicated bath is disinfected with 20 grams of potassium permanganate soaked for 15 20 minutes or 500 grams of crystal trichlorfon cubic meters soaked for 15 minutes.

Reasonable stocking density is too large or unreasonable combination will make the activity space of fish relatively reduced, and the fish will secrete too much adrenaline hormones, and the physical strength will decrease, thereby increasing the chance of enrichment and dispersal. Strengthen management to avoid stress response and improve the resistance of the fish itself.

Feed the bait. 100 grams of trichlorfon mixed into 30 kg of bran or compound feed for 4 days.

Trichlorfon, 500 grams of 667 square meters of water surface.
