  • Method for controlling infectious diseases in fish and other aquatic lifeforms in a closed culture system
    Patent number: 5643571
    Abstract: A method for controlling infectious diseases in fish and other aquatic lifeforms, regardless of their developmental stage. The method of controlling pathogenic organisms detrimental to aquatic lifeforms includes steps of adding fish which are pre-immunized against one or more organisms pathogenic to fish to the same aquatic medium and with normal fish. The pre-immunized fish continuously and increasingly release antibodies against the pathogenic organisms into the same aquatic medium and can protect or prevent naive (normal, non-infected) fish or naive aquatic lifeforms from infection and are able to enhance the recovery of infected fish or any aquatic lifeforms infected with the same diseases.
