متن کاملUsing a fisheries ecosystem model with a water quality model to explore trophic and habitat impacts on a fisheries stock: A case study of the blue crab population in the Chesapeake Bay
Recent calls for the development of ecosystem-based fisheries management compel the development of resource management tools and linkages between existing fisheries management tools and other resource tools to enable assessment and management of multiple impacts on fisheries resources. In this paper, we describe the use of the Chesapeake Bay Fisheries Ecosystem Model (CBFEM), developed using th...
متن کاملA 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 ...
متن کاملMatrix-Based Modeling of Blue Crab Population Dynamics with Applications to the Chesapeake Bay
Blue crab (Callinectes sapidus) plays an important ecological and economic role in estuaries from South America to New England. It supports a large commercial fishery in the United States with approximately one third of the landings taken from Chesapeake Bay. I developed a stage-based matrix model of the blue crab population to address three key questions: What is the ability of blue crab popul...
متن کاملBlue Crab Summary_Blue Crab Status02001-8.5x11
The blue crab, Callinectes sapidus, is a keystone species which plays an integral ecological, economic, and sociological role in Chesapeake Bay. The blue crab functions as both predator and prey in the Bay’s complex estuarine foodweb and occupies a variety of critical habitats impacted by human activity. Blue crabs exhibit a complex life history, disperse between estuarine and marine habitats, ...
