Emerging diseases • Hepatopancreatic necrosis syndrome • Clinical signs • In early stages of the mortality, clinical signs were almost not clear. • P. monodon died at the age of 20-30 days post stocking (35-45 days age), • while white leg shrimp L. vannamei died at the age of 30-35 days (45-50 days age). • slow growth rate, • loose shells, • and discoloration, • swelled and soften liver, • atrophied hepatopancreas, • occasionally black spots in the necrosis hepatopancreas
Emerging diseases • Hepatopancreatic necrosis syndrome: Findings (Prof. Dr. Don Lightner) • Histology: • No lesions diagnostic of infection by the Necrotizing hepatopancreatitis bacteria G. {HP-B) or by microsporidians, were detected. • The main pathologies found within these hepatopancreas tissues are suggestive of a toxic syndrome. • The toxin responsible could possibly come from the environment (water, feed, etc.) or from some type of bacteria. • PCR: • ALL submitted samples negative with: • NHP, • Spiroplasma penaei, • Microsporidian: Enterocytozoon hepatopenaei

3. Strategy for Development of Aquatic Animal Health 5 years (2011 to 2015)
National strategy for five years development of aquatic animal health (2011 to 2015) • 1) to build up management system of aquatic animal health; • 2) to improve human capacities and technical authority; • 3) to strengthen national cooperation; and • 4) to strengthen international co operations and private sector involvements
National strategy 1) to build up management system of aquatic animal health: • Fully operation from central government to localities; • Legislations and regulations • Sufficient man-power for management; • Sufficient infrastructures; • Investment on: • Development and application of the eradication programmes for important diseases of aquatic species • Strengthen of aquatic animal disease surveillance system base on OIE guidelines • Application of GMP in veterinary drugs production • Strengthen quarantine and inspection of fish and fisheries products import/export based on OIE guideline on aquatic animal health code
National strategy 2) to improve human capacities and technical authority and capability on: • Epidemiology and surveillance, • disease reporting • risk analysis, • laboratory diagnosis, • disease control and warning; • quarantine and inspection; and • drug management.
National strategy 3) to strengthen national cooperation between DAH with: • National Agro Forestry Fisheries Quality Assurance Department (NAFIQAD); • Directorate of Fisheries; • Research Institutes for Aquaculture No.1, 2 and 3 (RIA.1,2&3) • Can Tho University; • Nong Lam University, Nha Trang University; • Fisheries colleges • Private sectors: VASEP, VINAFIS,…
National strategy 4) to strengthen international cooperation: • OIE • Disease reporting • Reference laboratories: diagnostic assistance, supports and consultancies; trainings and education; calibration programmes; and finding new diseases/problems • FAO/NACA • Consultancies, Trainings and education, finding new diseases • Assisting for financial support to strentheng aquatic animal health system and application of OIE standards • WCS (Wild Animal Conservation Society) • CITES • CODEX • WTO/SPS • Privates and Associations
