TH12754B - Methods for reducing bacterial contamination in aquaculture - Google Patents

Abstract

in an invention-based method Live organic food for aquaculture, such as rotifers and, in particular, Artemia, is treated with derivatives of Bacterial-killing isothiazol in order to inhibit Bacterial contamination Isothiazolin derivatives should be derivatives of 4-isothiazolin-3- transfer, in particular 5-chloro-2-methyl-4-isothiazolin-3. -Transfer and/or 2-methyl-4-isothiazolin- 3-transfer these derivatives. It can be added in such a state to an organic food growth medium, or coated on an organic cyst and/or incorporated into an enrichment product. Prepare the Enrichment Intermediary The invention also deals with cysts of coated living organic food. with the derivative of Isothiazolin that kills bacteria and with enrichment products which has such derivatives, drug patents

Claims (2)

1. Methods for reducing bacterial contamination during early embryo culture. Start in aquaculture Due to the effect of the addition of organic food life into it by treating the food These organic compounds with bactericides. Which is unique in that Prior to being added to such aquaculture, the live organic feed was raised in a growing medium in the presence of a derivative of Bacterial isothiazolinic in concentrations is effective for reducing the growth of bacteria in it. 2. Method according to claim 1 is unique in that organic food has grown. From cysts in the culture medium Where the bacteria-killing isothiazolin derivative is added. 3. The method according to claim 2 is unique in that such isothiazolin derivatives are By adhering to the cyst in quantity, obtaining such an effective dose in the culture medium is achieved. 4. Methods of claim 1 to 3. There is a peculiarity in that the quantity is used once. The result is between 1 and 7 parts per million. Ideally, it should have a value of 1.5 to 4 parts per million, and a more specific value, approximately 2 parts per million. 5. One of the 1 to 4 Claims Methods is unique in that. Organic food They are further enriched in the enrichment medium where the derivatives of Isothiazolin Killing such bacteria has been effectively added to reduce the bacterial growth in the medium. Enrichment of this 6. The method according to claim 5 is unique in that the isothiazolin derivative that kills Such bacteria It has been included in the Central Enrichment Preparation Product. 7.
