Conceptual and practical advances in fish stock delineation
Pita, Alfonso; Casey, John; Hawkins, Stephen J.; Villarreal, Manuel Ruiz; Gutiérrez, María-José; Cabral, Henrique; Carocci, Fabio; Abaunza, PabloThe fish stock delineation concept has now evolved informed by knowledge affordable from a variety of new genetic and geochemical life cycle tracers in addition to traditional morphometric, parasitological and life history trait approaches. These can be coupled with better definition of oceanographic processes enhanced by GIS-related modelling tools. Population structure and stock delineation are central consid...
