Calibrating virtual population analysis for fisheries stock assessment
(EDP SCIENCES, 2008-04)
Virtual population analysis (VPA) is often used for assessing freshwater and marine fisheries resources. One important component in VPA is to calibrate abundance estimates with a time series of abundance indices. One of ...
A production modeling approach to the assessment of the horseshoe crab (Limulds polyphemus) population in Delaware Bay
(National Marine Fisheries Service Scientific Publication Office, 2006-04)
Horseshoe crab (Limulus polyphemus) is harvested commercially, used by the biomedical industry, and provides food for migrating shorebirds, particularly in Delaware Bay. Recently, decreasing crab population trends in this ...
Relationships between Pacific salmon and aquatic and terrestrial ecosystems: implications for ecosystem-based management
Pacific salmon influence temperate terrestrial and freshwater ecosystems through the dispersal of marine-derived nutrients and ecosystem engineering of stream beds when spawning. They also support large fisheries, particularly ...
