Thailand: Cold Spell Exacerbates EMS Epidemic
Daniel Gruenberg reports: Record cold temperatures in Thailand have exacerbated the EMS epidemic, resulting in widespread emergency harvests (including a significant one at my farm).
I did a quick survey of hatchery managers, feed suppliers and processors that confirmed continued significant mortalities due to both EMS and WSSV in southern and eastern Thailand. A major feed mill reports that it's only operating its mill two days a week, and processors report that they are operating at less than 20% of capacity.
Interestingly, I have heard countless reports of "cures" or fixes for EMS, and yet I have not been able to confirm that even one of them works. There still remains a paucity of good research on management strategies for EMS that's based on good scientific methods, not just pseudo-science and rumors.
EMS is
early mortality syndrome, WSSV is
White spot syndrome
A bit more from the article:
A Thai newspaper reports: On Thursday, January 23, 2014, "Bangkok hit its coldest record in 30 years when the temperature fell to 15.6° Celsius (60°F)," said Songkram Aksorn, Deputy Director General of the Thai Meteorological Department. This year's cool season has been the longest for a decade, lasting for almost three months, Songkram said.
Boots on the ground measurement instead of reading the results of a computer model run. Big big difference.
