Ongoing production issues in shrimp farming, part 2

Effective implementation of biosecurity protocols in shrimp farming requires awareness, discipline and a commitment by farm owners to implement them. The authors take a close look at intensive nurseries and how to exclude pathogens, predators and competitors.

Dutch shellfish farmers bringing the sea onto land

Bivalve shellfish culture is a low-impact form of protein production, and in many cases is a net-positive for water quality. So why move it indoors? Smit & Smit in the Netherlands has a good argument for doing so.

On-site diagnostic kit identifies WSSV in shrimp

Loop mediated isothermal amplification (LAMP) is a highly specific technique that can amplify DNA in isothermal conditions. The kit can amplify the target gene of the pathogen using a single temperature and give results in one hour.

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.
