Weekly Overview: New Technology Proven to Reduce EMS Bacteria in Shrimp Ponds

2 December 2014, at 12:00am

GLOBAL - New water treatment technology has been found to reduce successfully the amount of Vibrio parahaemolyticus bacteria, which causes Early Mortality Syndrome (EMS), in shrimp ponds, writes Lucy Towers, TheFishSite Editor.

The new technology from Silver Bullet has been proven by third party researchers in lab and field trials.

The system has proven to be safe to shrimp and is designed in a way that is easy to install, user friendly and affordable. The Silver Bullet also generates its disinfectant from ambient air onsite, so does not involve the risks and dangers associated with storing and handling toxic chemicals.

Dr Silvia Gomez, Centro de Investigación en Alimentación y Desarrollo A.C. (CIAD) Government lab in Hermosillo, Mexico, verified a dramatic increase in shrimp survival from the use of the Silver Bullet Water Treatment System.

Dr Donald Lightner, University of Arizona Shrimp Pathology Research Lab, has also analysed and validated the Silver Bullet Water Treatment’s effect.

“We verified in our lab that the Silver Bullet was able to successfully reduce the amount of Vibrio parahaemolyticus without having a toxic effect on the shrimp.”

Plans to build a marine trout farm in Cornwall, UK, have been dropped. The plan for a demonstration farm began in September 2013.

Over the summer and early autumn, Cefas, The Crown Estate and the British Trout Association managed the process of selecting a commercial operator for the Cornwall Aquaculture Demonstration Project. While there were several expressions of interest in taking forward this work, they did not meet the project's terms of reference in the given timescale to deliver a project of the highest standard.

It was, therefore, decided that the current demonstration project would not be continued.

After thousands of wild and farmed salmon tests, US scientists have found no evidence of the Infectious Salmon Anaemia (ISA) virus in Pacific waters along Washington's and Alaska's coasts.

It is vital that fish farm operatives who are responsible for farmed fish are trained in their health and welfare. This will help to ensure that fish are free from disease and suffering whilst at the same time promote good productivity and comply with legislation.
