Genetic improvement programs for shrimp vary between Asia, Americas

There is a clear difference between the shrimp postlarvae traits that are economically important in Central and South America versus those of Asia, creating a challenge for breeders to satisfy the somewhat opposing breeding goals the regions demand.

Realizing economic benefits from selective breeding

Although not universally practiced, the potential benefits of selective breeding in aquaculture outweigh all other options for improving animal performance. The genetic potential of aquaculture animals is plastic and can be improved over a relatively short timeframe.

China rebuilds fleshy shrimp industry

In China, fleshy shrimp have had much higher market value than other shrimp species. China’s aquaculture scientists and fishery agencies have therefore worked closely with shrimp farmers to rebuild the farming industry for F. chinensis.

Finfish genetic improvement

Although the application of selective breeding and genetics can yield dramatic results, the use of genetically improved stock varies widely among aquaculture sectors. Virtually all Atlantic salmon and rainbow trout producers use improved stock, while use of genetically improved tilapia

Genetic diversity of HPV parvovirus

Hepatopancreatic parvovirus is linked to growth retardation in shrimp. In a study, the genomic sequences of HPV from Mad­agascar and Tanzania were com­pared to those from Australia, Thailand and Korea.
