Release technology of silverfish in reservoir
As far as possible, the choice of release site is in the reservoir bay with a certain distance from the shore, a water depth of about 2 meters, and rich in small-scale bait organisms such as hard sediment or gravel bottom and insects, and several delivery sites should be selected at the same time to avoid failure caused by improper delivery of one point. Fish egg delivery method when the fertilized eggs are transported to the destination, the nylon bag containing the fertilized eggs is first put into the water. When the water temperature in the bag is basically the same as the water temperature in the reservoir (the temperature difference is less than 3 ℃), the fertilized eggs are dispersed into the water slowly and evenly, and each input point should have a certain standard.

Fishing techniques of beach enclosure on large water surface
Due to the large area and difficult fishing, most farmers still release water to fish during New Year's Day and Spring Festival every year, which not only wastes water, but also affects the income because of the concentration of fresh fish on the market. In order to solve this contradiction, the technicians of the farm in Linhai Farm of Jiangsu Agricultural Reclamation have explored the new technology of beach culture and fishing in large water surface after years of practice. Taking advantage of the habit of fish swimming at the top, a fishing pond with a width of 3 meters, a length of 5 meters and a depth of 2.5 meters is built at the water change outlet of the fish pond, leaving a water outlet 1 meter wide on one side of the pond.

Analysis of Drug use in Fish Culture
In recent years, the aquaculture industry in China has developed rapidly, and the intensive degree of aquaculture is also improving rapidly. at the same time, the aquaculture environment is also deteriorating, which makes the immunity and disease resistance of breeding objects decline, and the incidence rate is significantly improved. and due to the mutation of pathogens and other factors, new diseases and difficult diseases appear frequently. At present, these diseases are mainly treated with drugs. In this paper, the development, classification, factors affecting the action of fishery drugs and the problems existing in the use of fishery drugs in China were discussed. I. the distribution of fishery medicine

Local method to save fish poisoning
In real life, we often see the phenomenon of fish poison fish in small rivers and streams. If we are not careful, it often threatens the raised pond fish. At this point, the best way is to block the toxic water into the pond first; at the same time, human urine on the whole pool of water splash. The dosage is about 25 kilograms of human urine per mu of water surface at an average depth of one meter (i.e. 667 cubic meters). After the water reaches 50 kilograms, the whole pool is evenly sprinkled, which has obvious effect on rescuing newly poisoned or unpoisoned fish. 2. Tea bran poisoning Tea bran is usually used in poison ponds or in small amounts to prevent fish diseases

Application of simple facilities for temporary Fish Culture
At present, there are many flowing aquaculture farms in Sichuan, which mainly breed some cold-water fish, and most of their breeding facilities are cement ponds. In the earthquake, these cement pools are damaged to some extent by the earthquake destructive force, which may cause pool leakage and so on. If it is not repaired in time, the water in the pond may be lost, which will cause a crisis to the survival of aquaculture aquatic organisms, and even all the water in the pond will run out, resulting in the death of aquaculture aquatic organisms and huge economic losses to farmers. If you want to

How to save the fake dead pig

Problems easily overlooked in the process of selecting and retaining reserve pigs
(1) The selection and retention procedure is unreasonable and the selection and retention process is simplified: in some pig farms, the selection and retention process of reserve pigs is very simple, and there is no fixed procedure. Only after the breeding pig knot test is completed, the selection and retention can be simply evaluated, which is easy to cause imbalance in the selection and retention amount of each bloodline and decline in breeding pig production performance. Therefore, the selection and retention of reserve pigs should have a fixed procedure as a basis. Generally, the selection and retention of reserve pigs should go through three processes: primary selection, middle selection and fixed selection. Primary selection refers to the selection group with 4 times the number of reserved seeds when the farrowing segment is transferred to the breeding segment; middle selection refers to the development from young breeding to fattening.

The operation chose to cut the skin backward along the midline from the last pair of nipples 2cm, and the size of the incision depended on the size of the testis. Bluntly peel off the subcutaneous tissue to expose one side of the total sheath and press the testis close to the incision with your fingers.
