Text:
The expansion of aquaculture in the last 10 years has made it an important source of protein worldwide. However, increased production, and the culture intensification it carries, results in higher risk of infectious disease due to poor water quality and high stocking densities. Disease has several negative effects on fish, which include reduced feed efficiency, impaired growth and death, representing a direct loss of investment in feed, labour and other inputs.
