Abstract
The current trend in aquaculture development is towards
increased intensification and commercialization of aquatic
production. Like other farming sectors, the likelihood of major
disease problems occurring increases as aquaculture activities
intensify. Disease is now a primary constraint to the culture of
many aquatic species, impeding both economic and sociadevelopment in many countries. Addressing health questions
with both pro-active and reactive programmes has become a
primary requirement for sustaining aquaculture production and
product trade. It is reported that the principal diseases in cage
aquaculture of marine finfish and shellfish in Asia are caused by
environmental and management affects, nutritional causes, and
viral, bacterial, parasitic, and fungal pathogen
