7 acres of farming in Meizhou by Boss SunYellow catfishIn the pond,Yellow catfishThe phenomenon of swimming began to appear on the 2nd, and there were only a few at first, but it was not taken seriously at the time, thinking that it was a stress reaction caused by a sudden drop in temperature. However, the next day, the number of fish began to increase and the fish died. Microscopic examination revealed that the fish was only infectedSmall melon worms, but at this point it isSmall melon wormsRampage on the 9th day, almost allYellow catfishThey have all been wiped out.
For this catastrophicSmall melon wormsOutbreak, we have to understand that this is not an isolated case, similar situations inAquacultureMedium is not uncommon. In winter and spring, the temperature is lower, exactlySmall melon wormsThe best time to breed has led to many fish ponds suffering from it not long after the seedlings are releasedSmall melon wormsof pond infestation.
Small melon wormsIt is a cryptonuclear parasite that produces a layer of cysts to protect itself after maturity, which makes it difficult for the drug to penetrate the cysts, resulting in limited efficacy. In addition,Small melon wormsAlso known as the irritating cryptonucleus, the rate at which it reproduces is directly proportional to the degree of stimulation, which results in more intense insecticidal effortsSmall melon wormsThe number is also increasing. In addition,Small melon wormsIt stimulates the fish to secrete mucus, which can also affect the arrival and use of the drug.
In order to preventSmall melon wormsIn view of the treatment experience over the years, the following methods can be used for reference:
Dried chili peppersThe use of: can beDried chili peppersAfter cooking, pour water directly into the fish pond. Use 9 catties per acre of fish pondsDried chili peppersThe method of use is to splash water once on the first day, and then once on the second day, and then once after about 3 days.
Dried chili pepperswithGingerThe combination of use: after cookingDried chili peppersAdd an appropriate amount to the mixGingerand then splash water on the fish pond. Use 5 catties per acre of fish pondsDried chili peppersand 3 poundsGinger, use once every other day, three times in a row.
Copper sulphatewithBromochlorohydantoinCombined use: Use firstCopper sulphatebefore adding the solutionBromochlorohydantoin。The specific use method is the first time to use 05 poundsCopper sulphateand 200 gramsBromochlorohydantoin, distributed on the water surface per acre, the second use of 07 poundsCopper sulphateand 200 gramsBromochlorohydantoin, the third time to use 1 cattyCopper sulphateand 200 gramsBromochlorohydantoinand use once every other day. In the interval between the use of these drugs, some multi-organic acids can be used for detoxification, three times in a row, for a total time of 6 days.
Currently for:Small melon wormsMethods are still limited, and no specific drugs have been found. Therefore, prevention remains paramount. Topical administration can be used to inhibit parasite growth. Stubborn insect net is a kind of purityTraditional Chinese medicineThe extract, which has the effect of repelling parasites with high efficiency, does not produce an antidote, and does not cause harm to the fish body and water quality. In this way, the negative effects of the use of highly irritating insecticides on fish and water quality can be avoided.
Small melon wormsThe problem of pond drainage is inAquacultureIt often appears in the fish pond, which poses a huge threat to the health of the fish pond. Although currently targetedSmall melon wormsThere are limited methods, but they can be effectively reduced by paying attention to preventive measures and using drugs rationallySmall melon wormsinvasion, reduce losses. At the same time, we should strengthen the management of aquaculture water quality and maintain the hygiene of fish ponds to provide a healthy environment for fish to grow.
InAquacultureIn order to continuously learn and explore new prevention and control methods, and to share experience, can it be helpful to deal with itSmall melon wormsproblems. Only by strengthening cooperation and working together can we protect fish ponds from itSmall melon wormsof violations.
