摘要：
THE PRESENT INVENTION RELATES TO A METHOD OF CONTROLLING INFESTATION OF FISHES (110) BY LEECHES (120) DURING A CULTURE CYCLE OF THE FISHES (110) IN A CAGE (320). THE METHOD INVOLVES BREAKING OF THE LIFE CYCLE OF THE LEECHES (120) FOR CONTROLLING THEIR POPULATION WITHIN THE PERIOD OF THE CULTURE CYCLE. THE METHOD INCLUDES THE STEPS OF: A) PROVIDING A SUBSTRATE (210) WITHIN THE CAGE (320) SUCH THAT THE LEECHES (120) CAN FORM COCOONS (220) ALSO ON THE SUBSTRATE (210), AND B) TAKING THE SUBSTRATE (210) OUT OF THE CAGE (320) ON A DAY BEFORE MOST OR ALL JUVENILE LEECHES (120) ARE HATCHED FROM THE COCOONS (220). THE METHOD HELPS IN PREVENTING THESE JUVENILE LEECHES (120) FROM INFESTING ON THE FISHES (110). THE PREFERRED STRUCTURE AND MATERIAL FOR THE SUBSTRATE (210) ARE ALSO PROPOSED. THE MOST ILLUSTRATIVE DRAWING: FIGURE 3C
