The Vibrio bacteria in shrimp: how a common pathogen in shrimp farming became the leading character in the EMS story. During the past year, evidence has accumulated on how the ongoing outbreak of early mortality syndrome (EMS) or more precisely acute hepatopancreatic necrosis disease (AHPND) is caused by a specific strain of the Vibrio parahaemolyticus bacteria. That this newly emerged disease is ...

Introduction Cyanobacteria, blue-green algae, harmful algae, and toxic algae are words that can confuse people who are trying to decide on pond water safety. Certain algae can cause serious problems when they become very abundant in drought, hot weather, unusual rainfall patterns, or after nutrient accumulation in pond water. Fortunately, most ponds do not experience toxin problems or dense algal ...

A phytobiotic was able to reduce Vibrio counts in intestine and hepatopancreas leading to an increase in survival and better health. Shrimp farming is growing very fast in recent years, due to the high profit margins which present a good opportunity for those with interest in this sector. In Asia the production of Pacific white shrimp (Litopenaeus vannamei) was more than 3 million tonnes in ...

With phytobiotics not always the best dose is the higher. Plants can have a strong flavour and sometimes animals just reduce the intake because of that, that is why lower doses sometimes shows better resul ...

1. Hot summer limit the oxygen dissolved in the water even you add more paddle wheels it will not work effective as partial covering by orchis mesh - farmers has started partial cover of the ponds in the hot season instead of adding more paddle wheels.2. After big raining the algae collapsed that resulted in exhausted DO in the bottom and favorable pathogen bacteria bloom plus stressful from pH, s ...

Feed management and Aeration at the rate of 1 HP paddle wheel/ 10 Kg of feed/ day is the key. Applying standard probiotics in pond water and through feed will support the system effectively.
