Japanese Hatchery-based Stock Enhancement: Lessons for the Chesapeake Bay Blue Crab

A Model for the Population of the Blue Crab in the Chesapeake Bay

We model the population of the Blue Crab in the Chesapeake Bay by using differential equations. Blue crabs are inherently cannibalistic of juveniles, while also in competition with juvenile blue crabs for resources. These differential equations describe the intraguild predation consistent in the blue crab food web, as well as the cannibalistic nature of the blue crab. We introduce an aging and ...

Landscape-based geostatistics: a case study of the distribution of blue crab in Chesapeake Bay

Geostatistical techniques have gained widespread use in ecology and environmental science. Variograms are commonly used to describe and examine spatial autocorrelation, and kriging has become the method of choice for interpolating spatially-autocorrelated variables. To date, most applications of geostatistics have defined the separation between sample points using simple Euclidean distance. In ...
