Marine shrimp sessions at aquaculture America 2002: shrimp

摘要

Aquaculture America 2002, the national conference and exposition of the U.S. Chapter of the World Aquaculture Society (WAS), the National Aquaculture Association (NAA), and the U.S. Suppliers Association (USASA) was successfully held at the Town & Country Resort in San Diego, California, on January 27-30, 2002. Several excellent shrimp papers were presented covering topics like nutrition and feeds, health, genetic improvement, production and others. I will comment briefly on some of the most relevant papers, and those interested in additional information should refer to the Book of Abstracts, available from the World Aquaculture Society Home Office (phone 225-388-3137; fax 225-388-3493; wasmas@aol.com). Dhar et al. reported on a quantitative assayfor measuring TSV and YHV viral loads in shrimp by real time PCR using SYBR green chemistry. According to the authors, this assay is a rapid and sensitive method for the detection of shrimp RNA viruses. The method is highly robust and is amenable to high throughput assays, and could be a useful tool for diagnostic and epidemiological studies in shrimp aquaculture. Dhar et al. also discussed genetic and antigenic variation of TSV. Their molecular and immunological data suggest the existence of at leasttwo strains of TSV among the samples tested.
