Can genetics help solve a limiting factor for China’s shrimp sector? We look at a study examining the high rates of non-spawning females in hatcheries. 

En ocho programas de mejora genética de camarón en siete países diferentes, las mejoras en el crecimiento han sido constantes en todos los programas, con tasas de mejoría anual entre 5 y 12 por ciento. Las mejoras en las tasas de supervivencia son menos previsibles y menos consistentes. 

In eight genetic improvement programs in seven different countries, growth improvements have been constant in all programs, with annual improvement rates between 5 and 12 percent. Improvements in survival rates are less predictable and less consistent. 

Las medidas de bioseguridad y las estrategias preventivas son esenciales en cualquier cadena de producción biológica. Los programas de bioseguridad adecuadamente planificados e implementados mejorarán la sanidad animal, la producción y la economía. 

El siguiente paso para la cría de camarones será el desarrollo de animales que no sólo están libres de enfermedades, sino que son cada vez más resistentes a múltiples patógenos. La industria se está globalizando, con proveedores estableciéndose en el extranjero. Pero su lugar de nacimiento siempre será Hawaii. 

Biosecurity measures and preventive strategies are essential in any biological production chain. Properly planned and implemented biosecurity programs will enhance animal health, production and economics. 

The next step for shrimp breeding will be developing animals that aren’t just disease-free, but increasingly resistant to multiple pathogens. The industry is globalizing, with suppliers setting up shop overseas. But its birthplace will always be Hawaii. 

Accurate PCR testing of shrimp seedstock assures shrimp farmers that their seedstock is clean of major diseases. Ring tests verify that labs conducting PCR testing are obtaining correct, reliable and reproducible results when testing for specific shrimp diseases. 

The presence of AHPND-Vibrio parahaemolyticus can be detected both in fecal DNA samples and in the enriched bacterial broth with samples of enrichment broth showing increased sensitivity. 

Since 2001, Moana Technologies has worked toward providing domesticated, genetically improved and specific pathogen-free (SPF) black tiger shrimp to farmers in Asia. Based in Hawaii, USA, Moana built a breeding base on wild-caught broodstock from seven locations in Asia. 

A five-year project was undertaken in Brunei Darussalam to develop advanced technology for the production of large black tiger shrimp. A combination of technologies has enabled efficient production of large-sized black tiger shrimp, which could lead to a resurgence of this species in Asia. 

For a five-year project undertaken in Brunei Darussalam to develop advanced technology for production of large black tiger shrimp, a comprehensive disease diagnostic laboratory was developed to enable detection of known and emerging shrimp pathogens by molecular and histological methods. 

The quality of postlarvae supplied by a shrimp hatchery can vary considerably. Common myths, such as acceptance of low survival and insufficient concern for water quality, can contribute to lower animal quality. 

As research on WSSV continues, commonsense steps can lessen the potential impacts of white spot syndrome virus on shrimp-farming operations. 

Basic components of biosecurity include knowledge of diseases, adequate detection methods and the use of “clean” shrimp stocks.
