The high temperature season is the golden season for aquaculture, and it is also a critical period for aquaculture management. Due to strong sunlight, high temperature and water temperature, the metabolism of fish is strong, the water quality of the water body changes rapidly, and fish diseases frequently occur, which seriously affect the production efficiency of fishery aquaculture. Now mainly introduces the prevention and control methods for the morbidity and fulminant epidemics. Grass carp Symptoms: Also known as "Aconitum argentatus", the main hazard is 1 to 2 years of grass carp. The scorpion septum is caused by bacterial infections caused by parasites such as ringworms, third-generation parasites, or mechanical injuries such as pulling nets. The diseased fish is rotted, the end cartilage is exposed, the zygomatic flap is grayed or white, and dirt or mucus is attached to the edge of the zygomatic flap; the inner epidermis of the zygomatic is often congested, and the epidermis of the middle part is often corroded into a round shape when severe. Or irregular transparent skylights, also known as "open skylight." Control measures: The first day (sunny days) with copper sulfate and ferrous sulfate mixture 0.7 g / cubic meter (5:2) Quanchiposa or sprinkle with insecticide. The second day to the fifth day of feeding rotten spirit or intestinal fistula. On the third and fifth days Quanchip spilled dibromohydantoin, bleach, chlorine killing spirit and so on. Fulminant epidemic Symptoms: The main hazards are salmon, squid, head lice, and grass carp. In early onset and acute infection, the fish were anorexia, motionless, or mad at swimming pools, chaos, and failure. Diseased fish, the upper and lower jaw, mouth, lid, eyeball, fin base and fish on both sides of congestion, anal swelling, abdominal swelling, abdominal cavity water. Prevention and control measures: The disease has an acute onset, a long duration of disease, a widespread epidemic, and a heavy hazard. Comprehensive treatment measures must be adopted to achieve satisfactory therapeutic effects. The steps are as follows. 1 On the first day of killing fish ectoparasites, crystal trichlorfon (90%) can be used, 0.5 grams per cubic meter of water, or spilled to stop bleeding. 2 Feed the baits on the second to sixth days and feed them for 5 days or three yellow powders. 3 On the third and fifth days, Quanchiposa Chloride, Bromochlorohydantoin and Chlorine Dioxide (1 or 2 types are optional). 4 On the eighth day, the water quality was adjusted, and the whole pond was splashed with lime slurry to improve the water quality, adjust the pH of the water body, create a good water environment, and meet the fish growth requirements. 10000Hz High Frequency LiDAR Module 10000 Hz is one of our 2021 new solutions products,which can be widely used in drone postioning, car anti-collision, intelligent traffic monitoring etc. with high accuracy.
