Mexico - shrimp farming is facing a mysterious disease problem

UPDATE 17/08/13: Laboratory results reported as follows

"The preliminary findings of the official laboratories in shrimp analyzed show a wide variety of genres such as Vibrio and Aeromonas bacteria that affect the body called the hepatopancreas, which were also identified high concentrations of heavy metals such as cadmium, lead and arsenic and a high viral load for Hypodermic disease and Infectious Hematopoietic Necrosis, IHHNV, "the statement added.

Excerpt from article:

A state official reported that there were 520 farms in the state with 35,000 hectares of ponds.  On farms, mortalities varied from 15 to 85 percent.

The states of Sonora and Nayarit face similar problems.

Ten different laboratories are attempting to determine what is causing the mortalities, including Dr. Donald Lightner’s laboratory at the University of Arizona in the United States.

Mexico has EMS

UPDATE 20 March 2014

Neil Gervais in an interview with Shrimp News International says;

How EMS got into Mexico is not known and probably will never be known.  Why they’re susceptible is because of the way they were selected.  Now hatcheries in Mexico are looking for animals that are disease tolerant in non-biosecure environments.  I don’t think EMS will be as devastating when—and I do mean “when”, not “if”— it crosses the borders into Central and South America.  I believe this because no country south of Mexico is using animals that were exclusively SPF and selected for growth only.

To quote Huffington's post, Periplaneta japonica has special powers: it can withstand the New York winter, outdoors in the freezing cold.

Whilst the subject is still debated, there are some who say that, as any other invasive species, this cockroach should be monitored.

Will competition with other American cockroaches eliminate the new comer? Or will it multiply and thrive as it did in Asia, where this is a common pest?

Only time will tell... and perhaps the horizon scanning function of IBIS will help come up with an answer faster.

Viral nervous necrosis is resulting in severe economic impacts on the farmed marine finfish sector across South East Asia. It seems as marine finfish aquaculture increases throughout the Asia/Pacific so do problems associated with VNN. You could safely say that nearly everyone in the Asia/Pacific marine finfish aquaculture industry has encountered problems associated with a nasty nodavirus. The recent problems on a grouper farm in the Philippines (de la Pena /et al/. Bulletin of the EAFP 2011, 31, 129-138) is a timely example of how VNN manifests to impact heavily on an emerging and potentially lucrative industry. In this case the source was the farms' stockfeed influents, trash fish. VNN or no VNN, the practice of feeding aquatic animals of unknown health status to other aquatic animals seems to be at the root of this and many similar health problems in aquaculture.

Forecast: VNN will most likely be the biggest bottleneck to grouper production in the S.E. Asian region until better health management can be implemented across this aquaculture sector.
