What to catch in the management of fish species in autumn
Clear the pond. Transfer the fish to a pond that has been cleaned and sterilized for cultivation. If there are difficulties in the turnover of water sources and fishing ponds, all the fish species can be transferred out of temporary culture, then disinfect the original ponds with 75 kg ~ 100 kg quicklime per mu, and fertilize the water quality according to the conventional method, and return the fish species after the medicine disappears. Separate cultivation. Adjust the fish species according to different specifications, so that the specifications of the fish species in the same pond are the same.

The problem of slow growth of small fish
The proportion of colorful immortals infected with nematodes and flagellates is relatively high, especially in the growth stage of small fish, the growth rate of small fish slows down after infection; adult fish will suddenly lose appetite, lose weight day by day, abdominal swelling and weight loss on the back, and can also cause enteritis and ascites. Capillary nematodes and flagellates have good effects. Growing fish and breeding fish can be fixed and used interchangeably with Baibi every month. When the colorful immortal is infected with capillary nematode disease, if it has been obviously anorexic and emaciated that it has been severely infected, it should be quarantined regularly with capillary nematode agent.

During treatment, red potion can be applied directly to the injured area (which should not be applied to the eyes), or diseased fish can be soaked in 1/1000000 to 2 dilute solutions of antibiotics (such as tetracycline, furacillin, etc.). Anti-inflammatory ointment (such as erythromycin ointment, tetracycline ointment) can also be applied to the injured area.

Five methods to improve the efficacy of fishery medicine
The viscosity of the improved adhesive should be strong, otherwise the drug is easy to be lost in water. Standard wheat flour is a better raw material for adhesive. It is best to make pellet bait or ball bait for swallowing fish. Fish with food attractants have such a keen sense of smell that they can still be identified even if 1 gram of alanine is dissolved in 1 million liters of water. For example, Chinese herbal medicine with strong flavor, such as star anise and Angelica dahurica da

It is fastidious to cast fish in early spring.
The quality of fish species of the same age requires the same specifications, similar body length and weight, thick back muscles, bright color, intact scales and fins, normal activity, strong traceability, Gill cover not stretched in the basin after leaving the water, the tail does not bend, beating more than, there are no scars and parasites on the body surface. Fish species disinfection some farmers do not disinfect fish seeds at all, resulting in high incidence, and the effect of drug control is not ideal. in fact, as long as we do a good job in disinfection of fish species, we can often get twice the result with half the effort in the prevention of fish diseases.

Relationship between disease of eel culture in soil pond and water environment
The water environment is the decisive factor for raising eel. The water environment not only determines whether eel can be cultured, but also directly affects the yield, and finally affects the economic benefits of eel culture. Therefore, only by improving the water environment can we raise eels well. The following focuses on analyzing the relationship between eel disease and water environment from the following aspects. 1. The pH value in pH water is an important comprehensive water quality index, which directly affects the physiological status of eel. When the biological, chemical or physical composition of the water body changes, it will be shown in the pH value, and the eel in the soil pond requires the pond water.
