PCR-based tools aid biosecurity via detection of WSSV
Offering high sensitivity and specificity, polymerase chain reaction (PCR) assays are the most accepted molecular method for white spot syndrome virus (WSSV) detection.

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 nutrition from feed.

Biosecurity: Not just a word
Most aquaculture farms rely on general strategies for biosecurity that implement protocols learned from others. Establishing effective biosecurity, however, can be complicated due to multiple interacting variables.

Strategies for managing large integrated shrimp farms
Integrated shrimp farming is desirable due to its ability to provide food safety and traceability. Production planning is the most essential exercise in integrated systems.

Disease risk evaluation
Assessing disease risk at an aquaculture facility allows the anticipation of possible outbreaks and subsequent production losses. It can also help to identify weaknesses of the production system.

Biosecurity principles for sustainable production using SPF shrimp
Basic components of biosecurity include knowledge of diseases, adequate detection methods and the use of “clean” shrimp stocks.

Biosecurity for shrimp farms
With the global spread of viruses, biosecurity has become an essential element of every shrimp farm. Biosecurity starts with quality of farm design.

Designing a biosecurity plan for shrimp aquaculture, part 2
The objective of a contingency plan is to quickly recover production through rapid initial response and effective implementation of biosecurity measures. Such plans depend on whether the detected pathogen or disease is exotic or endemic, its potential economic impacts and whether it is to be eradicated.

Designing a biosecurity plan for shrimp aquaculture, part 1
The development of an effective biosecurity plan requires full understanding of facility design and operations, and knowledge of the animals’ health status and the transmission modes of pathogens in order to identify the risks and define meaningful measures.

Bacterial testing improves biosecurity at marine hatchery
Microbial surveys of hatchery operations at Oceanic Institute found a strong correlation between hatchery success and cultivable bacteria levels in the water supplied to the larval-rearing systems.

Advancing shrimp farm technologies support greater efficiencies, sustainability
Todays' shrimp farm technologies include biosecurity protocols, stocking densities according to pond design and aeration levels, and best practices for pond preparation and feed and water management.
Responsibility
Health management in recirculating systems
Recirculating systems and health management schemes should be designed concurrently to maximize their effectiveness.

Effective biosecurity requires more than window dressing
Biosecurity in aquaculture involves actions designed to maintain the health of aquatic animals by reducing the introduction of pathogens to facilities.

Biosecurity in intensive aquaculture: Don’t build without it
Construction of an intensive aquaculture production facility without serious attention to biosecurity nearly guarantees outbreaks of infectious disease.

Biosecurity basics for shrimp aquaculture
Biosecurity in shrimp aquaculture is achieved by preventing the presence, growth, and spread of pathogenic microorganisms.

Biosecurity and closed recirculating systems
Effective biosecurity requires environmental isolation in a closed system, like RAS, to culture cephalopod species (squid, cuttlefish and octopus).
