  Cost-effective biosecurity crucial for shrimp farming

  Many shrimp producers give only perfunctory attention to routine biosecurity at hatcheries and farms. A cost-effective biosecurity program for farmed shrimp requires reliable diagnostic tools to make timely decisions to control or exclude pathogens.

  Four AHPND strains identified on Latin American shrimp farms

  Two virulence genes are known to encode a binary photorhabdus insect-related toxin that causes acute hepatopancreatic necrosis disease in shrimp. The pathogenicities of these V. campbellii strains were evaluated through laboratory infection and subsequent histological examination in P. vannamei shrimp.

  As ocean temperatures rise, so too will vibrio outbreaks

  A study using a half-century of data has linked climate change and warming sea temperatures with an increase in illnesses from the common vibrio bacteria. Shellfish growers, fighting a particularly virulent strain of Vibrio parahaemolyticus, are changing their harvest protocols.

  Low-salinity culture water controls Vibrios in shrimp postlarvae

  In a survey of Vibrio concentrations in white shrimp postlarvae at two inland farms, hatchery postlarvae were acclimated in water with salinity reduced from 30 and 5 ppt to 2 ppt at the farms. One farm stocked postlarvae in nursery

  Polymerase chain reaction: How useful is it?

  Polymerase chain reaction testing is a powerful tool that can detect very low levels of pathogens, but its ability to screen and produce results that represent the population is often oversimplified. Screening of the wrong tissues or too few animals

  Do current shrimp practices favor EMS?

  After refilling ponds, surviving microorganisms – including Vibrio parahaemolyticus, which causes EMS in shrimp – may benefit from the availability of nutrients in sediment and water and lack of competing microorganisms.
