Microencapsulated organic acids aid shrimp culture

A novel blend of organic acids (OAB) microencapsulated in a lipid matrix and supplemented in the diets of Litopenaeus vannamei enhanced their growth, phosphorus utilization, resistance to Vibrio harveyi and immunity. This may have implications as an eco-friendly prophylactic strategy.

Limited decomposition enhances PCR detection of AHPND Vibrio in shrimp

A study confirmed the utility for improved polymerase chain reaction (PCR) detection of the Vibrio bacteria that cause acute hepatopancreatic necrosis disease (AHPND) in asymptomatic shrimp by permitting the shrimp to expire and decompose for several hours prior to preservation

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.
