A special session on Regional Cooperation for Improved Biosecurity was held at the World Aquaculture Adelaide 2014 conference, from 7-11 June. The session discussed i) regional cooperation in biosecurity, ii) dealing with emerging diseases, focussing on acute hepatopancreatic necrosis disease, and iii) domestication programmes and their implications for genetic diversity, disease susceptibility and resistance.

The emergence and spread of new or previously unknown infectious diseases has had very significant impacts on public health, food security and international trade. Disease emergence is the consequence of environmental and/or sociological changes that disrupt the ecological relationship between pathogens and their natural hosts. Understanding the drivers of disease emergence will help us develop policies and practices that will reduce opportunities for disease emergence in aquaculture and improve prospects of containment.

A new method for the detection of AHPND-bacteria (AP4) has been published and is available for download. The advantage of the AP4 method over the previously published AP3 method is that it has 100 times higher sensitivity. Because of its higher sensitivity, the bacterial culture enrichment step needed when using the AP3 with low levels of AHPND bacteria may be omitted. However, the AP4 method should not be considered as a replacement for AP3.
