The leeches refer to the two major classes of zooplankton, such as the larvae and the copepods, which are rich in nutrients and easy to digest. They are palatable feeds for fry and fingerlings. Artificially cultivated otters feed fish at low cost, have a fast growth of fish, and have a good yield increase effect. The method is:
First, the pool was built earthen ponds and concrete ponds can be. The depth of the pool is about 1 meter. The size of the rectangle is 10 square meters to 30 square meters.
Second, the water in the pool water of about 50 cm deep. Daphnia Suitable water temperature of 18 ℃ ~ 25 ℃, pH value of 7.5 to 8, dissolved oxygen saturation of 70% to 120%.
Third, fertilizing the soil pool water per cubic meter throw four kilograms cow, horse manure or other livestock manure, 1.5 kg of straw, wheat straw or other non-toxic plant stems and leaves as basal dressing 10 days after the first, with the amount of basal fertilizer, after which, where appropriate, in accordance with color Topdressing to keep the color brown. The cement pool will cast 1.5 kg of cattle, horse dung or other animal excrement per cubic meter of water, and 1.5 kg to 2 kg of geotextile. After every 8 days, it will be top-dressed once again. The top dressing will be 0.75 kg of cattle, horse manure or other animal manure.
IV. Breeding Whether it is an earthen pond or a mud pool, a mixture of yeast and inorganic fertilizer can be used. For each cubic metre of water, 20 grams of yeast is inoculated, and the yeast can be soaked in water for 3 hours to 4 hours before being poured into the pool. 65 grams of ammonium carbonate and 37.5 grams of ammonium nitrate per cubic meter of water are applied. After every 5 days, the yeast is applied. Its usage is half of the beginning. After the yeast is put in, the water is exposed for 1 to 3 days, and then the leeches can be planted. The amount of seeds used is 30 g to 50 g per cubic meter of water.
5. After 15 days to 20 days into the pool for fishing, the species can be covered in the entire pond after extensive breeding. At this time, feed fish in batches. Usually every 1 day to 2 days to fish once, once the total amount of 10% to 20%. In the water temperature of 18 °C ~ 20 °C environment, you can often fishing, continuous.
Antipyretic:
Something that reduces fever or quells it.
There are 3 classes of antipyretic medications that are sold OTC (over-the-counter) without prescription:
Salicylates -- aspirin (acetylsalicylic acid), choline salicylate (Arthropan), magnesium salicylate (Arthriten), and sodium salicylate (Scot-Tussin Original);
Acetaminophen (Tylenol); and
Nonsteroidal anti-inflammatory drugs (NSAIDs) -- ibuprofen (Advil), naproxen (Naprosyn, Aleve), and ketoprofen.
From anti-, against + the Greek pyretos, fever from pyr, fire. The same root gives rise to pyrexia, a medical term for fever.
Antipyretic, from the Greek anti, against, and pyreticus, pertaining to fever, are substances that reduce fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, resulting in a reduction in fever.
Most antipyretic medications have other purposes. The most common antipyretics in the United States are ibuprofen and aspirin, which are used primarily as pain relievers. Non-steroidal anti-inflammatory drugs (NSAIDs) are antipyretic, anti-inflammatory, and pain relievers.
Pain-killer:
Painkiller is any member of the group of drugs used to achieve analgesia, relief from pain.
Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which reversibly eliminate sensation. Analgesics include paracetamol (known in North America as acetaminophen or simply APAP), the non-steroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, and opioid drugs such as morphine and oxycodone.
In choosing analgesics, the severity and response to other medication determines the choice of agent; the World Health Organization (WHO) pain ladder specifies mild analgesics as its first step.
Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants.
