METHOD FOR PREVENTION AND CONTROL OF INFECTIOUS DISEASES OF SHRIMP SPECIES BY USING COBIAS

摘要

The present invention relates to the field of aquaculture, relates to a method for the prevention and control of infectious diseases of shrimp species by using cobias, comprising the following steps: deploying postlarvae of Penacus orientalis into seawater having a salinity between 2 and 33, where the amount deployed is between 30,000 and 100,000 postlarvae/are, and, when the Penacus orientalis develop to weights between 0.3 g and 0.7 g, deploying cobias weighing between 90 g/fish and 110 g/fish, where the amount deployed is 50 fishes/are. Numerous experiments proved that cobias weighing between 90 g/fish and 100 g/fish in shrimp farming ponds feed on diseased or deceased shrimps first, and that healthy shrimps have a minimal probability of being eaten due to habits thereof. This feature solves the problem of reduced survival rate of farmed shrimps due to healthy shrimps being preyed on.
