The power of entire DNA sequences to secure the future of seafood

A new review of the contribution of genomics to seafood management reveals how new questions may be addressed by genetics. Genomics involves sequencing the complete DNA of organisms, which has a great variety of applications, including greatly enhancing our ability to define management units, tracing whether seafood is being labelled correctly when sold, identifying how often salmon stray from their streams of origin, detecting seafood diseases, and measuring the extent of fisheries-induced evolution. The authors conclude that the application of genomic methods to fisheries management and aquaculture should be expanded. The paper was coauthored by SAFS professor Kerry Naish and appeared in Trends in Ecology and Evolution.
