Northern white shrimp
Considering samples from North Carolina (USA) to Campeche (Mexico) there is some evidence of genetic separation of a population of northern white shrimp on NW Atlantic (U.S. Atlantic coast) from a population in the Gulf of Mexico (Ball & Chapman, 2003). US stocks are assessed at federal level and management measures can be defined at federal and/or stadual levels: Northern Gulf of Mexico and NW Atlantic. A distinct assessment unit exists in Campeche Bank (Ramos-Miranda et al., 2009).
