Controlling parasitic diseases in aquaculture: new developments.

Abstract: The expanding global aquaculture industry is urgently in need of more effective methods for the control of parasitic diseases. Advances in our understanding of parasite biology, host parasite interactions and improved diagnostic methods using new technologies which contribute to better management and control are highlighted in this chapter. There is an increasing volume of research pointing to effective control without the use of chemical interventions. The processes leading to increasing regulation and cost of drugs and chemicals are described. Their integration into a more sustainable pest management strategy is discussed and the imperative for the inclusion of resistance management principles in any strategy is emphasised.
