1. Water
The fishes in Ganghsin pond feed on small zooplankton such as rotifers and nauplii. Therefore, 3 to 5 days before the fishes are planted in ponds, the manure should be splashed with water in an amount of 22.5 to 45 kg per 100 square meters. Fertilizer to meet the nutritional needs of fry.
There is a certain correlation between the growth rate of fry and the biomass of rotifers. The rotifer biomass was in the range of 0-30 mg/l, and the daily growth rate of fry was accelerated with the increase in the number of rotifers. There was a positive correlation between the two; the rotifer biomass was in the range of 32-160 mg/l. The greater the number of rotifers, the lower the daily growth rate of the fry and the negative correlation between the two. Therefore, controlling the rotifer biomass is extremely important. For fish fry ponds, the biomass of rotifers is 20-30 mg/l (7000-10000/l).
Water body rotifer biomass inspection method: In the sunny noon, a small number of graduated cylinders randomly take a few milliliters of pond water. Looking at the light, the milky white dots with large dust are the rotifers and count the number of them. The number of milliliters of water. Take a few more points to average, such as 10 rotifers per milliliter of water, that is, to achieve fertilizer standards. Observing water quality is best in grayish-white waters, yellow-green, greenish green, and yellow-brown.
2. Stocking
Once the aquaculture waters and fry are ready, they can be stocked. The method is to put the fry in the container first, and after the fry is in normal operation, splash the egg yolk water (boiled duck egg or egg yolk, wrap with 2 layers of gauze, rinse in the container), make it satiation (fish fry can be digested visually A light yellow line appeared in the road. After about 10 to 20 minutes, the seedlings were placed in the upper wind. When laying the seedlings, place the container into the pool water, slowly pour it out, and then use your hands to disperse the fry.
The amount of culture is generally based on the size of the outlet. If cultivating 3.3 centimeters of summer flowers, 150,000 tails will be cultured per 667 square meters of water; if a fingerling of more than 7 centimeters is cultivated once, 80,000 to 100,000 tails per 667 square meters will be raised; if it is to be raised once in a short period of time For fish species above 10 cm, it is appropriate to breed 50,000 to 70,000 fish per 667 square meters of water surface. If three stages of cultivation are adopted, generally the amount of 200,000 to 300,000 fish per 667 square meters of water is used to raise the fry and fish seedlings, cultivate for 10 to 15 days and reach 2 centimeters or so; and then press 30,000 to 50,000 yuan per 667 square meters. The rearing amount of the fish is raised for ten to fifteen days, and then it is divided into summer flower specifications and the fish species are cultivated. If the ponds are in good condition, the amount of baits and fertilizers will be high, the date of polyculture will be early, and the cultivation techniques will be high. The culture density can be larger.
3. Precautions
The water in the fry pool should be strictly filtered, and the net should be pulled out 1 time before the breeding to remove the predators. One day prior to the release of the fry, the cage was placed in the pond and a small amount of fry was placed. The water was tested for half a day or one night. If the fry was safe, the fry was expected to be reared. The water temperature of the fish pond and the water temperature in the transportation tool must not differ by more than 2°C. Otherwise, the water should be added slowly until the fry is adapted to the stocking. Fry generally dominated by monoculture.
Antiviral:
Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics and broad-spectrum antibiotics for bacteria, most antivirals are used for specific viral infections, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit their development.
Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, or antiviral drugs based on monoclonal antibodies. Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from viricides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Antivirals also can be found in essential oils of some herbs, such as eucalyptus oil and its constituents.Related Products:antiviral drugs,anti-cancer drugs.
Anti-cancer:
Anticancer, or Antineoplastic, drugs are used to treat malignancies, or cancerous growths. Drug therapy may be used alone, or in combination with other treatments such as surgery or radiation therapy.
