First, the source and quality requirements of fingerlings
1. Source of fingerlings: Fingerlings are generally derived from fingerlings raised in fingerling pools and fish fingerlings in adult fingerlings. Alien fingerlings must be produced from pollution-free aquaculture bases.
2. Quality requirements of fish species: Fish species require strong physique, no disease or injury, and exercise.
3.Strong physique, disease-free and injury-free: Well-prepared fish species are plump and full of muscles, normal body shape, complete scales, smooth body surface, body color and eye crystals, fresh lustrousness, and the hand is not covered and the tail is not bent. The beating is fierce, and it is strongly backwatered in live water boats. It swims intensively in cages. The head is down and the tail is up. It seems that only the tail is not seen. The fish with poor physique, the muscles are thin, and the scales are incomplete. The watch is less glossy and its activity is weak. To try to choose good fish species, in order to ensure a higher culture yield.
4. After exercise: The fish species are trained and screened in the fingerling ponds by pulling nets. After cages are densely raised before putting them into adult fish ponds, their resistance to adverse environments can be enhanced. Such fish species have a high survival rate for transportation and rearing.
Two species quarantine
Fish species should be properly quarantined at the place of origin. If any disease is detected, they should be treated in the original pool. After the fish species are recovered, they can be discharged to prevent the spread of fish diseases. Ensure the health of fish species.
Three species of fish under the pool
Before fish ponds, use 2~3% of salt water to disinfect the fish body for 2~5 minutes. Put the fish species into the pool at the upwind mouth of the fish pond. Do not stack the fish. The fish movement should be light and fast. When in the lower pool, the water temperature in the container and the temperature in the fish pond may not exceed 3°C. Different types of fingerlings should be fed in batches into different adult fish ponds.
Before the pond is cleared, the fish ponds of the fish species are stocked, and a small amount of fish is used to test the water in the adult fish pond. After half a day or one day, if the fish lives normally, it indicates that the drug toxicity of the pond pond has disappeared before it can be decided. All fish species were released into adult fish ponds.
For the treatment :
[Of all the diseases of the nervous system, the most common difficulty that people have is pain, and much of that is nerve-related," according to Dr. Shai Gozani, founder and CEO of NeuroMetrix, a medical device company. [There are 100 million people who live with chronic pain."
According to the Mayo Clinic, patients with nerve disorders experience functional difficulties, which result in conditions such as:
Epilepsy, in which abnormal electrical discharges from brain cells cause seizures
Parkinson's disease, which is a progressive nerve disease that affects movement
Multiple sclerosis (MS), in which the protective lining of the nerves is attacked by the body`s immune system
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a motor neuron disease which weakens the muscles and progressively hampers physical function
Huntington's disease, which is an inherited condition that cause the nerve cells in the brain to degenerate
Alzheimer's disease, which covers a wide range of disorders that impacts mental functions, particularly memory.
Mayo Clinic also noted that the nervous system can also be affected by vascular disorders such as:
Stroke, which occurs when there is bleeding on the brain or the blow flow to the brain is obstructed;
Transient ischemic attack (TIA), which are mini-type strokes that last a shorter period of time but mimic stroke symptoms; and
Subarachnoid hemorrhage, which is specifically bleeding in the space between your brain and the surrounding membrane that can be the result of a trauma or rupturing of a weak blood vessel;
Infections such as meningitis, encephalitis, polio, and epidural abscess can also affect the nervous system, the NIH noted.
Treatments vary from anti inflammatory medications and pain medications such as opiates , to implanted nerve stimulators and wearable devices, Gozani said. [Many people also turn to herbal and holistic methods to reduce pain, such as acupuncture."
