In practice, many farmers do not have the awareness of preventing fish diseases, so they should pay more attention to prevention and treatment. Farmers often think that fish do not get sick in the water, and there is no need to prevent it, but wait for fish disease to occur and then go to medication, at this time already sick into plaster. Unlike terrestrial organisms, aquatic animals are not so easy to administer drugs, and the measurement is difficult to grasp. Drugs can only save a small number of diseased fish, but they still have no effect on most diseased fish. As a result, economic losses are often caused to farming production.

Misconceptions in administration methods

Drug use without looking at symptoms: Drug use blindly without a clear diagnosis of the condition, which may lead to other diseases. It not only fails to achieve the goal of disease control, but also causes economic waste.

Urgent and indiscriminate medical treatment: the problem does not follow the objective law when it comes, and medical treatment everywhere causes drug damage, which not only does not solve the problem, but also aggravates the death.

Blind dispensing of drugs: Some farmers randomly mix drugs without paying attention to drug taboos, resulting in weakened or enhanced efficacy, and may also have side effects.

Drug spraying is not uniform: some farmers sprinkle drugs on the edge of the pond at will, resulting in drug poisoning in part of the water beyond the tolerance of fish, while some fish can not get timely treatment, delaying the opportunity of treatment.

Use expired medicines: Some high-Year egg breeders take out expired or ineffective medicines without looking at the shelf life, which can not play a role in preventing and treating fish diseases, but also produce some toxic and side effects.

Drug resistance is not considered: long-term use of the same drug in the treatment of fish diseases in aquaculture results in drug resistance in fish. Repeated use of this drug will reduce or ineffective the efficacy of the drug.

Fear Psychology: Excessive disinfection, insecticide, random increase of drug dosage, adverse effects on future healthy growth.

Blind cost reduction: in order to save costs, leading to slow down the growth rate of farmed animals. Instead of reducing costs, it increases costs and reduces economic benefits.

Water quality is regulated by a fixed mode: the whole aquaculture process is regulated by a single scheme. Not only did our eggs fail to improve water quality, but they also increased the cost of breeding.

Pursuing individual indicators: a superficial understanding of physical and chemical indicators, ignoring the importance of water balance.

Ignoring water quality analysis: Some high-Year egg-raising farmers do not consider the impact of deterioration of water environment on fish. They blindly use fishing drugs whenever there is a disease. They often neglect the link of water quality regulation. As a result, the effect of preventing and controlling fish diseases can not be achieved, but it is harmful and unhelpful.
