Title of Thesis: SPATIAL ECOLOGY OF BLUE CRAB (CALLINECTES SAPIDUS) IN CHESAPEAKE BAY Olaf P. Jensen, MS, 2004 Thesis Directed By: Professor Thomas J. Miller, Marine, Estuarine, and Environmental Science Department Spatial heterogeneity is a striking feature of the blue crab life history and fisheries in Chesapeake Bay. However, a quantitative assessment of their spatial distribution and the fa...
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 کاملDiet selectivity of juvenile blue crabs (Callinectes sapidus) in Chesapeake Bay.
Shallow coves in Chesapeake Bay have abundant food and serve as nursery grounds for juvenile blue crabs. In this study, we examined the relationships between the diet of very small (4-40 mm CW) juvenile blue crabs and the benthic infauna in shallow, unvegetated nursery coves. We compared infauna in benthic samples with gut contents of juvenile blue crabs from six shallow coves in each of two su...

Blue crabs Callinectes sapidus (Rathbun, 1896) > 100 mm carapace width were sampled from a constructed oyster reef (1996 and 1997), a sand bar (1997) and a natural oyster bar (1997) in the piankatank River, Chesapeake Bay, USA to describe habitat use, sex ratios, and demographics across a gradient of habitat types. patterns of blue crab catch-per-unit-effort (CpUE), and demographics were simila...
متن کاملThe Effects of Derelict Blue Crab Traps on Marine Organisms in the Lower York River, Virginia
—Derelict (abandoned or lost) traps targeting blue crab Callinectes sapidus have the potential to affect the blue crab fishery and other marine-oriented species. We used sidescan sonar to locate derelict traps and assess their extent and accumulation rate. Experimental traps were monitored at four locations to calculate catch rates of marine organisms and trap degradation rates. In 2006, 635–67...
