1. Choose high quality fish species

Fish species are the primary material basis for fish farming, and stocking high-quality fish species is an important condition for achieving high yields. Quality fish must meet the following requirements: 1 good shape. Bright and shiny body, scales, fins intact, no damage, no illness. 2 good physical condition. Back abdomen is thick, muscles are plump and flexible, swimming is lively, and water is strong. In an intensive environment, the head swings downward and the tail swings upward. 3 The specifications are the same. Individuals of the same batch of fish are tidy and uniform in size. Those who do not meet the above conditions are regarded as poor quality fish species.

2. Master the timing of stocking

Generally, the best time for freshwater fish rearing fish species is from the winter solstice to the beginning of spring (from late December to early February). This is because the water temperature in winter is low, the fish's activity is weak, and the scales are tight. During fishing, transportation, stocking and other operations, the fish body is not prone to mechanical trauma, and in particular, it can reduce the infection rate of erythroderma and water mould. During this time, the fish's metabolism slowed down and it was not prone to hypoxia. In winter, stocked fingerlings are essentially stocked in advance, allowing the fish species to adapt to a new living environment for a longer period of time, ie extending the growth period. When the water temperature exceeds 10°C, the carps begin to ingest food and grow, so that they can make full use of the natural feeds of the water body to make up for the energy consumption during the winter and restore the normal physique before the prosperous period.

3. The best place to buy fish species

The fish species required for pond stocking should be based on local production, and it is advisable for the fish farms (households) to cultivate large-scale fish species on their own. As a result, production can be planned to meet the needs of stocking; secondly, long-distance transport can be avoided to cause the death of fingerlings and increase the survival rate of fingerlings.

4. Fish stocking precautions

When you put fish in winter, you must choose a windless, warm sunny day. Do not operate in windy, rainy or snowy weather to avoid frostbite and bleeding. The fish container is required to be smooth, and the fish should be moved lightly when it is under the pond. Thoroughly immerse the barrels (pots) containing the fish in the pond water so that the fish can swim into the fish ponds themselves to avoid injury to the fish. Fish seedlings must be soaked and disinfected with a solution of drugs before the ponds are tangled (for specific methods, see the disinfectant drugs and their methods of use described below) to kill the body surface parasites. Grass carp species also need to be vaccinated against disease.

IV Infusion

IV Infusion:

Intravenous simply means "within vein" (or "inside the vein"). Therapies administered intravenously are often included in the designation of specialty drugs. Intravenous infusions are commonly referred to as drips because many systems of administration employ a drip chamber, which prevents air from entering the blood stream (air embolism), and allows an estimation of flow rate.

Intravenous therapy may be used to correct electrolyte imbalances, to deliver medications, for blood transfusion or as fluid replacement to correct, for example, dehydration. Intravenous therapy can also be used for chemotherapy.

Compared with other routes of administration, the intravenous route is the fastest way to deliver fluids and medications throughout the body. The bioavailability of the medication is 100% in IV therapy.

Intravenous infusions are fluid solutions administered through a vein. There are numerous different types of solutions available, but they can be broken down into simple categories depending on the function they serve. Some replace lost fluids, and others provide nutrients, replace lost blood, and deliver medications.

One of the most common uses for intravenous infusions is to replenish fluids lost through dehydration. These infusions often contain normal saline solution, a combination of sterile water and sodium chloride. This solution is known as an isotonic crystalloid, or a solution that contains the same amount of electrolytes as plasma in the body. It is used in cases of moderate to severe dehydration, such as that caused by vomiting or diarrhea, when replacing the fluids quickly is vital.

When a patient`s gastrointestinal tract is compromised and nutrients cannot be absorbed - or eating can worsen the condition - intravenous infusions called total parenteral nutrition may be given. These solutions contain a mix of sterile water, electrolytes, sugar, proteins, fats, and other nutrients, depending on the needs of the patient. Diseases and disorders that commonly require total parenteral nutrition include late stages of Crohn`s disease, obstructive bowel disorder, and ulcerative colitis.

Intravenous infusions are also used to deliver medication directly to the blood stream. Certain medications, such as intravenous immunoglobulin, a type of antibody, can only be given through the vein. Other medications, such as certain narcotic pain relievers, are given intravenously because the method allows them to they work faster than when taken orally. Chemotherapy for treatment of cancer is also typically given intravenously.

When performed by a medical professional, intravenous infusions are typically safe. The most common reaction is mild pain and redness at the site of the injection, although different medications may cause different side effects. Any time the skin is punctured, there is a risk of infection. Having a medical professional, typically a nurse, monitor the intravenous infusion and change the injection site when irritation is evident can help prevent complications.
