Antibiosis fishing medicament processing method

Abstract

The invention discloses an antibiosis fishing medicament processing method, and has the advantage that the antibiosis fishing medicament prepared by the method contains a macro-molecule system of starch / chitosan / gelatin, and the system can form a macro-molecule interpenetrating network structure, thereby the antibiosis fishing pills prepared by the method have an obviously improved stability in seawater and are not easy to be dispersed; in addition, gelatin, chitosan and starch three compositions belong to natural large molecules which are friendly to environment, and in the preparation process, water is used as a solvent for starch dextrinization at first, and then another two compositions are gradually added; according to detection, the antibiosis fishing medicament obtained by the processing method has the advantages of uniform internal porosity structure, large porosity, uniformly distributed apertures, good connectivity between apertures, thereby the fishing medicament can be uniformly distributed in the carrier.

Description

technical field [0001] The invention relates to a processing of fishery medicine, in particular to a processing method of antibacterial fishery medicine. Background technique [0002] In coastal cities, aquaculture plays a pivotal role in economic development, and in order to prevent diseases of aquatic animals, antibacterial drugs (such as florfenicol, etc.) must be put into the breeding area. The current drug delivery method is generally to put it directly or mix it into the feed, but because the antibacterial drug is easily dissolved in the water after contacting the waters, first of all, its drug delivery efficiency is too low to ensure that fish, shrimp and other aquatic animals eat it, and it cannot Estimate the amount of food and medicine for each aquatic animal, so its efficacy cannot be guaranteed, and it is very blind; secondly, it is also easy to pollute the water quality of the water area. Since the water area is mobile and public, it will also affect the health ...

Problems solved by technology

The current drug delivery method is generally to put it directly or mix it into the feed, but because the antibacterial drug is easily dissolved in the water after contacting the waters, first of all, its drug delivery efficiency is too low to ensure that fish, shrimp and other aquatic animals eat it, and it cannot Estimate the amount of food and medicine for each aquatic animal, so its efficacy cannot be guaranteed, and it is very blind; secondly, it is also easy to pollute the water quality of the water area. Since the water area is mobile and public, it will also affect the health of other farmers. Breeding quality

[0003] For this reason, an antibacterial fish medicine and its processing method are disclosed in the Chinese invention patent specification whose application date is September 29, 2010, and the patent number is ZL201010296388.6. Sugar, 18-80% starch and 1.2-20% veterinary antibacterial drugs; the advantage is that this method uses chitosan and starch as carriers, and veterinary antibacterial drugs as drug models to make antibacterial fish medicines. The drug carrier made of polysaccharide and starch is insoluble in water, has no pollution to water quality, and can be naturally degraded in water or fish, and the degradation products have no toxic side effects on the environment. Drugs stored in this carrier are released slowly in water. It can ensure that most of the medicines are eaten by the farmed aquatic animals, and at the same time avoid the adverse effects of veterinary antimicrobials on the entire aquaculture waters; however, in actual use, it is found that the structure of the above antibacterial fishery medicines is not yet compact, and it is easier to sprinkle into seawater If it is not swallowed by the cultured animals immediately, it will easily lead to the loss of the drug in the seawater
