Physical, environmental, and chemical methods of disease prevention and control

Abstract

Disease prevention is a primary and cost-effective method in fish health management. It is more effective and economical than attempting to stop a disease that has already set in. Preventive measures have always big advantage over curative practices. Moreover, the drug may not provide remedies under all circumstances. Also, the drug may not help the host survive the infection until the environment is improved. Ideally, fish culturists should strive to decrease the stress-causing factors and eliminate and prevent the entry of pathogenic organisms by strictly adhering to the fish health monitoring programme.
