Improving the survival rate of fry flowers

The cultivation of aquatic fingerlings is commonly referred to as “flowering,” which is the first important link in fish production. Aquatic fish fry body is small and tender, and it is poor in adaptability to the environment. It is a little careless and will cause a large number of deaths. Production needs to do the following: 1? Dredging and disinfection: for the flower pond, the fish should be drained about half a month before the release of pool water, clear debris in the pool, so that the sun exposure after a few days to pick Thick mud, keep 3 to 5 cm thick at the bottom of the pool. Then 60 to 80 centimeters of new water, 100 to 120 kilograms of lime with water clear pond, kill the harmful organisms and bacteria on the fry. 2? fertilizer water Fangmiao: Many years of practice has proved that the fertilizer water Fangmiao not only high survival rate of flowers, and fry growth is also fast, neat and consistent. Generally after 3 to 5 days of disinfection in the clear pond, the large manure that has been fermented is poured into the pool, which is about 100 kilograms per mu. After about 7 days of fertilization, the food rotifers in the pool water will reach a peak, and the fry can be released at this time. 3 test water Fangmiao: The day before the release of seedlings to test whether the toxicity of disinfectant drugs disappeared. The method is to use a large washbasin full of pool water, put dozens of tail water fish fry, 6 to 8 hours after the fry are still normal activities, indicating that the drug residue has disappeared, you can put seedlings. If abnormal fish fry or death is found, it indicates that the residual drug of Qingtang has not completely disappeared, and the fish should be released after the toxicity completely disappears. 4 : Sitting in a pot to eat, temperature adjustment under the pond: from the field to buy back the fry, because after transportation, in the next pond before the first "sitting pot" method is to use large fish pots (or large plastic pots, etc.) to install a small amount of water, Transfer the fry returned from the oxygen bag into the pot and allow it to return to normal. Then use 1 boiled egg yolk per 100,000 fry. Gently pour into the bowl with water and let it float. After the pond. When the ponds are to be tested by hand, whether the water temperature in the fish bowl is the same as the water temperature in the pond, if there is a significant difference in the hand feel, it is necessary to adjust the temperature. Otherwise, the fish will be caught in the lower pond due to a temperature change, resulting in a large number of deaths. The temperature adjustment method is: use a bowl or cup to dip the water in the pool into the fish bowl, add a bowl (cup) every few minutes, and add the bowl into the basin when the water temperature in the basin is nearly the same as the water temperature in the pool. Into the pond. When laying seedlings, it should be noted that windy weather should be placed in the windward winds of ponds, windless weather should be released in deep water, and fish should be prevented from falling from a height to the pool. Fish ponds should be moved into ponds. Hold the side of the pond by hand and tilt the bowl to allow the fish to swim gently into the pond. On sunny days with higher temperatures, do not put seedlings at noon. 5? Master the density, the implementation of a single raising: the density of fry flowers should not be too dense, not too thin, generally blue, grass fry to put 100,000 mu, oysters, clams and other fry acre 12 to 150,000 tail is appropriate. Fish fry flowers should only be raised in a single way and cannot be polycultured, otherwise it will affect the survival rate and the specifications will not be neat. 6? Strengthen management, timely ponds: fish ponds under the pond after the water according to the fertilizer, in line with the principle of a small amount of ground facilities, timely application of decomposed manure, or spilled milk, to ensure that the fry have enough food. Adhere to early, middle and late inspections. Walk around the pool every morning and use a washbasin to catch fish and observe its growth and activity. As the fry grows, fresh water is added every 5 to 7 days, and the depth of water injection is about 5 cm. After 15 to 20 days of floriculture, the fry can grow to 2 to 3 cm, which should be dilute in ponds to reduce the occurrence of diseases, accelerate the growth of fry and increase the survival rate. The fry flowering stage coincides with the Meiyu season. During this period, the fry is prone to whiteheads, trichotomosis, and white skin disease. We must pay attention to water quality management and do a good job of drug prevention. If a fish disease occurs, the cause must be quickly identified and the medicine should be prescribed.
