Grass carp fingerlings high yield technology

In recent years, in order to increase the breeding efficiency, the majority of farmers have changed the past stocking mode, from the previous carp to the current submerged fish. At the end of the year, grass carp is more popular. Therefore, the seeds of grass carp have been better sold in recent years. In order to adapt to the situation and to increase the benefits, the fish breeding in our field in recent years has also increased the proportion of grass carp seed culture and stocking density. Through the exploration in recent years, the level of fish species reared by grasshoppers in our farm has been greatly improved. The average yield per mu has reached 400kg, and the high yield has exceeded 500kg. This is a brief introduction to the technology of grass carp seeds that I farm at the farm.
1, the preparation of Tangkou. The Tongkou in my field is after the end of the summer flower. The fish species will be cultured in ponds. In some places, summer flowers will not be cleaned as they were before. However, the new water must be added during the summer. A week or so before the pond, when adding new water, use an 80-mesh sieve to filter in the water.
2, stocking mode and proportion. In order to maintain a good grassy fish species of the year, the stocking pattern is very important. If the number is too small, the yield will not be able to keep up, and if the number is too large, it will not grow long. At the same time, attention should be paid to the mix of varieties. In general, the grass carp is 8000 to 10,000 in summer, and a small amount of carp is also stocked. Each mu can stock about 2000, and other varieties do not need to be increased.
3, daily feeding management. Feeding should be combined with fine and green materials. The fine material should be fed with pellet feeders using a feeding machine. The green material should be fed to duckweed (our locals are commonly called “秧花”). Concentrated feeds should be fed early, and feeds should be fed first (ie, small pellets, broken feeds), fed twice a day, once in the morning and once in the afternoon, and the feeding time determined based on the fish’s eating and drinking conditions. Usually, each half hour Up to 1 hour, the feeding amount and interval time can be adjusted. The green material is directly fed into the pond, but it is also necessary to use a bamboo raft for a place. When the food is almost enough, it can be returned to the river for feeding.
4, fish disease prevention. The duckweed fed because it was fished from the river, with many germs, and no disinfection, so feeding more will have enteritis, rot. Normally, once every 10 days or so, bleaching powder can be used for Quanchiposa disinfection. The dosage can be 1-2kg per mu per meter of water depth. During the high incidence period of fish diseases, copper sulfate and ferrous sulfate are also used to disinfect and sterilize. 0.7ppm (copper sulfate: ferrous sulfate = 5:2), in order to prevent hepatobiliary syndrome, can be added in the feed Baogan Ning, vitamins, Qianggan powder and other drugs bait. If the fish is in the attack stage, stop feeding green feed. Of course, there may be parasites, such as trichomonads, etc. At this time, trichlorfon, wheel nets, wheel nemesis, etc. should be used. When used at the beginning, it should be used in accordance with the instructions on the instructions, and it cannot be increased, otherwise it is easy to develop drug resistance.
After several months of meticulous feeding, the end of the year will be able to harvest grassy species of the year.

Antimalarial:

Antimalarial medications, also known as antimalarials, are designed to prevent or cure malaria. Such drugs may be used for some or all of the following:

Treatment of malaria in individuals with suspected or confirmed infection

Prevention of infection in individuals visiting a malaria-endemic region who have no immunity (Malaria prophylaxis)

Routine intermittent treatment of certain groups in endemic regions (Intermittent preventive therapy)

Some antimalarial agents, particularly chloroquine and hydroxychloroquine, are also used in the treatment of rheumatoid arthritis and lupus-associated arthritis.

Current practice in treating cases of malaria is based on the concept of combination therapy, since this offers several advantages, including reduced risk of treatment failure, reduced risk of developing resistance, enhanced convenience, and reduced side-effects. Prompt parasitological confirmation by microscopy, or alternatively by rapid diagnostic tests, is recommended in all patients suspected of malaria before treatment is started. Treatment solely on the basis of clinical suspicion should only be considered when a parasitological diagnosis is not accessible.


Antiparasitic:

Antiparasitics are a class of medications which are indicated for the treatment of parasitic diseases, such as those caused by helminths,amoeba, ectoparasites, parasitic fungi, and protozoa, among others. Antiparasitics target the parasitic agents of the infections by destroying them or inhibiting their growth;[4] they are usually effective against a limited number of parasites within a particular class. Antiparasitics are one of the antimicrobial drugs which include antibiotics that target bacteria, and antifungals that target fungi. They may be administered orally, intravenously or topically.

Broad-spectrum antiparasitics, analogous to broad-spectrum antibiotics for bacteria, are Antiparasitic Drugs with efficacy in treating a wide range of parasitic infections caused by parasites from different classes.
