Preparation methods of several Earthwork Fish drugs

In the prevention and treatment of fish disease, if the fish medicine can be prepared by using green plants or traditional Chinese medicine on the spot, it can prevent red skin disease, enteritis, Gill rot and other common diseases, avoid toxic side effects, and save expenses. In this paper, the simple preparation methods of several kinds of fish medicine are introduced as follows: Sanhuang powder rhubarb, Huangmeng and Huangzen are prepared by the proportion of 5 ∶ 3 ∶ 2. When in use, add 1 kg of "Sanhuang powder" and 0.4 kg of salt to every 10 kg of fish concentrate, and add appropriate amount of water to make granular bait for feeding once a day.

Poison bait has a good effect on trapping and killing beetles.

The copper green beetle has miscellaneous food habits, such as citrus leaves, mature peaches and grapes, etc., and the harm is quite serious. At present, there is a lack of effective pesticides. For this reason, we used poison bait to trap and kill, and achieved good results. When a large number of beetle adults appear from May to July, cut the mature watermelon (inferior melons) into several pieces, sprinkle a small amount of 3% Furadan granules on the surface of the pulp, separate them in soil pans, bamboo baskets and other containers, and place them on citrus tree forks. In a few days, a large number of beetles will be poisoned to death in watermelons. Change once a week

Scientific application of fishery medicine

Fishery drugs are all substances used to prevent, control and treat diseases, insects and pests of aquatic animals and plants, promote the healthy growth of cultured varieties, enhance disease resistance and improve the quality of aquaculture water. This paper introduces several correct methods for the prevention and treatment of aquatic animal diseases: first, there are many kinds of fishery drugs, and their physical and chemical properties are different. Therefore, before using fishery medicine, we must first accurately diagnose the main diseases and pathogens of the breeding and control objects, make a treatment plan, and then choose the right medicine to the case, otherwise not only

Misunderstanding of soaking and disinfection of eel seedlings

In many years of fishery production, aquaculture technicians have accumulated rich aquaculture experience. Using salt water to soak and disinfect fish fry is one of the traditional experiences of farmers everywhere. However, in practice, Chinese culture experts and some rice field eel farmers have found that the method of soaking and disinfecting fish fry with salt water, which is widely used in other fish, is not suitable for rice field eel culture. In early 2000, a scholar put forward the view that it is not safe to disinfect ricefield eel with salt water based on experiments. The experiment shows that the body of ricefield eel is treated with salt water.

Correct use of fishery medicine

With the rapid development of aquaculture, the problem of disease prevention and control has become increasingly prominent, so it is particularly important to master the correct use of fishery drugs. First, fish drug ① poisoning, including pesticide poisoning, red tide poisoning, seaweed poisoning, fishery drug poisoning, etc., different poisoning conditions, different treatment methods. ② malnutrition, chronic, long-span, should choose high-quality feed, should not be misdiagnosed as other diseases. ③ bacterial disease has the same symptoms as bacterial disease, and most antibiotics are effective. There is almost no ④ virus disease.
