Vibrio control in shrimp farming: Part 2

Strategies to control Vibrio bacteria at aquaculture farms must revolve around limiting inputs, including those from postlarvae suppliers, those that come in with the water, those that remain in the soil between crops and those in the feed and accumulated

Vibrio control in shrimp farming: Part 1

Control of Vibrio bacteria should focus on minimizing overall bacterial loads and the potential for horizontal transmission. The challenge for hatchery managers is identifying gaps in biosecurity and plugging them without creating niches for other potential pathogens.

Microsporidian impacts shrimp production

Enterocytozoon hepatopenaei (EHP), a microsporidian parasite widely found in Asia and other areas, is impacting aquaculture by severely retarding the growth of cultured shrimp. EHP infects the tubules of the hepatopancreas in shrimp, which damages the organ’s ability to gain

Common-sense biosecurity measures head off crop failures

Biosecurity can be defined as the operating procedures that shrimp hatchery and farm personnel use to minimize the impacts of disease on their animals. Proper biosecurity measures slow the movement of pathogens and protect unaffected areas.
