How to mix fishery medicine
With the increase of fish species and stocking density in ponds, the chances of simultaneous occurrence of different diseases of different fishes in ponds are greatly increased. In general, the effect of single use of fishery medicine is not good, but the method of mixed use of fishery medicine can obviously improve the curative effect. 1. The principle of mixing. It does not affect the chemical stability of the active components of the drug; does not increase the toxicity, the ideal effect is not to increase the toxicity; the efficacy is reasonable, the advantages are complementary; do not increase the cost of drug use. 2. Points for attention

Fish species are knowledgeable about autumn tube.
First, clear the pond in time. After 2 ~ 3 months of fish breeding ponds, the water quality has generally aged, natural bait decreased, hydrogen sulfide and other harmful gases and pathogens increased. After entering autumn, the fish species should be transferred to the pond which has been cleaned and sterilized for cultivation. Where there are difficulties in the turnover of water sources and fish ponds, all the fish can be temporarily reared, then the original ponds can be disinfected with 75kg ~ 100kg of quicklime for every 667 square meters, and the water quality will be fattened according to the conventional method, and the fish will be returned after the medicine disappears.

Introduction of commonly used drugs for fish 1
At present, there are many kinds of drugs commonly used in fish culture in the market. As the production of fish medicine is not standardized, some of the products of various manufacturers are not marked with active ingredients, and the trade names of some similar proprietary medicines are not unified with the corresponding chemical names. This is not conducive for us to understand the effective components of drugs, and it also causes some difficulties for the scientific and rational use of drugs. In order to popularize the technology of prevention and control of fish diseases, we will introduce the knowledge of commonly used drugs in fish culture one after another. In order to improve our understanding and understanding of commonly used drugs, we can use drugs scientifically and rationally in production.
