The basic role of fishery drugs The ultimate goal of the use of fishery drugs is to improve the disease resistance of aquatic animals and control the occurrence of aquatic animal diseases. Its basic role can be roughly divided into three categories: 1. Suppress and kill pathogens. Anti-microbial agents and anti-parasitic drugs, etc., are absorbed into the body and organ tissues and directly act on pathogens. 2. Improve the culture environment. It aims to improve the breeding environment by killing pathogens in water, improving water quality and sediment quality, and purifying the breeding environment. 3. Regulate the physiological functions of aquatic animals. In order to increase the feed conversion rate, some drugs that can regulate metabolism and promote growth are often added to the feed. These additives generally do not have the function of diagnosing and treating diseases, and are mostly used to improve the utilization of feeds. At present, the commonly used drugs for regulating the metabolism and growth of aquatic animals in aquaculture production include minerals, vitamins, amino acids, lipids, hormones, and enzyme preparations. Fishery drug administration 1. Splash method: also known as the whole pool sprinkled. Use a method that has a relatively large killing effect on certain pathogens, and uses drugs that are safe for animals, such as fish and shrimps, to sprinkle evenly in culture tanks with a certain concentration. When using this method, the volume and dosage of aquaculture water must be correctly calculated. 2. Suspension method: also known as hanging basket (bag) method. That is, the drug is contained in microporous containers or cloth bags, hung around the food or where aquatic animals often appear, and the purpose of administering the animals is to use the habit of feeding the animals to food in the food field or living activities. 3. bath method: also known as dipping method. The cultured animals are concentrated in a smaller container or body of water, a higher concentration of the drug solution is prepared, and the drug is forcibly received within a relatively short period of time to kill the pathogens on the body surface and the sputum. 4. Dipping method: The collected Chinese herbal medicines are tied into bundles and placed in the vicinity of the food field in the culture pond, or in the inlet of the pond, at the upper wind head, etc., and the active ingredients in the dip are spread into the culture pond. Inhibits or kills pathogens in the water and on the surface of the fish and on the gills. 5. smear method: also known as rubbing method. Collect the sick aquatic animal, wrap the aquatic animal with wet gauze or towel, and then directly drip the drug at the lesion or smear with cotton swab to kill the pathogen or prevent the wound from being infected. 6. Oral administration method: The drug is uniformly mixed into the bait, and a palatable bait is prepared after feeding. Dosages are generally calculated based on the farmed species and their body weight, and some are calculated on the weight of the bait. 7. Filling method: Actually it is a compulsory method of oral administration. The method is to anesthetize aquatic animals, then use a rubber catheter to infuse the prepared liquid into the stomach or intestine, and place it in a container filled with clean water until it is cured or until it is cured for the second time. medicine. This method is generally only applicable to a small number of large aquatic animals. 8. Injection: There are two major intramuscular injections and intraperitoneal injections.
