・殺菌方法としては、ろ過器よび薬剤の添加による方法
が最も一般的で広く行われている。Conventional technology Purification and sterilization of water is an important issue in raising and raising fish in a healthy manner. As a conventional method for purifying and sterilizing water for raising and breeding fish, the most common and widely used method is to use a filter and add chemicals.
発明が解決しようとする課題
ろ過による方法は用水の浄化と除菌の効果はある程度期

、筐た薬剤に要する費用も比１咬的高価である。It cannot be expected to have a sterilizing effect on fish pathogens such as mold. When using small-scale drug administration or chemical bathing methods, it is necessary to appropriately select the drug to be used depending on the type of fish pathogen, and to be careful in adjusting the dosage.Furthermore, when using fish for food, In order to prevent the drug from remaining in the fish body, we have strictly set limits on the fish species that can be used for each drug, upper limits on dosage, and a prohibition period for drug use (somatic drug period) before the fish can be shipped for human consumption.
This must be strictly observed. Furthermore, although the effectiveness of several vaccines against viral diseases has been reported, there are currently no commercially available vaccines in Japan, and the reality is that there are no effective drugs. Furthermore, when chemicals are added to the water used for raising livestock and rearing, it is difficult to sterilize the water under running water, and the cost of the chemicals is comparatively high.
