We invite you to join us for the 10th Symposium on Diseases in Asian Aquaculture (DAA10), the popular triennial event of the Fish Health Section of the Asian Fisheries Society (FHS-AFS), to be held from 28 August to 1 September 2017 at The Anvaya Beach Resort, Kuta, Bali, Indonesia.
With the chosen theme of “Enhancing Aquatic Animal Health Research and Services through Public-Private Sector Partnerships” we anticipate to cover topics from classic parasitic, bacterial and viral diseases to emerging trends and cutting-edge research in aquatic animal health.
Three satellite workshops: FAO’s Inter-regional Workshop, NACA’s Meeting of the Asia Regional Advisory Group on Aquatic Animal Health, and a Bioinformatics Workshop are being organised back-to-back with DAA10.
Hepatopancreatic microsporidiosis (HPM) caused by Enterocytozoon hepatopenaei (EHP) is a newly emerging disease of cultivated shrimp in Asia. Current evidence indicates that it can be associated with severe growth retardation that may not be clearly evident until the second month of culture and that it may even cause low continuous mortality in the case of very severe infections.
Here we present a new method for detecting Enterocytozoon hepatopenaei (EHP) that has superior specificity to the first generation SSU-PCR developed in 2009 when the genetic information of EHP was still limited. Due to the urgency in stemming losses to HPM, we have decided to release this method for free, non-commercial use to the global shrimp farming community.
The second generation EHP detection method presented here is based on a gene encoding a spore wall protein (SWP) of EHP (SWP-PCR). Results from our laboratory work revealed, in contrast to SSU-PCR, that the SWP-PCR method did not give cross reactions with DNA from crabs infected with H. eriocheir and E. canceri. From these results, we recommend that the new SWP-PCR method replace the first generation SSU-PCR method.
The sequences of the primers for the SWP-PCR method (nested PCR) are given below and can be used freely for non-commercial applications to detecting EHP. Please contact Centex Shrimp (ornchuma.its 'at' mahidol.ac.th) to obtain a free positive control plasmid (pGEM-EHPSWP).
Prizes include: Power banks, fitness watches, USB sticks and t-shirts
FishVet Group Asia Limited is collecting data on the geographic spread and impact of EHP (Enterocytozoon hepatopenaei).
All farmers who complete a short survey form by 30 June 2016 will be included in a prize draw with the following prizes:
All data will be kept strictly confidential.
The Second International Technical Seminar/Workshop on AHPND: There is a way Forward! will be held from 23-25 June 2016 at the Sukosol Hotel in Bangkok, Thailand.
The purpose of the meeting is to update knowledge and exchange experiences in dealing with AHPND, to validate current concepts and models under different systems and environmental conditions and to put into action the responsibilities of the different sectors (i.e. government, producer and academe) as a way forward to deal with AHPND.
The meeting will consist of three technical sessions looking at EMS/AHPND through the lens of the industry, the academe and the government sectors and a fourth session on the way forward.
All interested stakeholders are welcome to attend. A catering fee of US$40 / day applies (includes lunch plus morning and afternoon tea). Reservations will be accepted until close of business on 10 June; places are limited.
Audio recordings of the presentations from the Special Session on Regional Cooperation for Improved Biosecurity, held at the World Aquaculture Adelaide 2014 conference, are available for download. 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.
Effective health management is a shared responsibility that requires a coordinated approach from all countries, particularly with regards to emergent pathogens such as "EMS" (acute hepatopancreatic necrosis disease of shrimp), where containment requires a rapid response from the international community. There are good reasons to believe that wide and increasing inbreeding is also a significant factor in the epidemics frequently observed in the aquaculture industry.
NACA would like to thank the Australian Centre for International Agricultural Research for providing a travel grant that allowed the speakers to attend the conference.
