The Chesapeake Bay has traditionally been one of North America's most productive fishing grounds, supporting the world's largest blue crab fishery. During the last several decades, fishing mortality and environmental degradation led to ∼ 70% drop in the bay's blue crab abundance, 84% decline in its spawning stock, and historically low levels of juvenile recruitment as well as nursery habitats being below carrying capacity. This situation makes the Chesapeake Bay blue crab an appropriate… 

Importance of Blue Crab Life History for Stock Enhancement and Spatial Management of the Fishery in Chesapeake Bay

Due to over-harvesting and habitat degradation, spawning stock abundance and biomass of the Chesapeake Bay blue crab (Callinectes sapidus) has declined over 80% in the last 15 years. In addition,

Stock Enhancement and Carrying Capacity of Blue Crab Nursery Habitats in Chesapeake Bay

Marsh-fringed nurseries are apparently below carrying capacity for the blue crab and could be enhanced through the release of hatchery-reared juveniles, suggesting that alternative prey did not deter predation on juvenile crabs, but instead led to higher densities of cannibalistic crabs through bottom-up control.

Release Strategies for Estuarine Species with Complex Migratory Life Cycles: Stock Enhancement of Chesapeake Blue Crabs (Callinectes sapidus)

This paper summarizes ongoing research to develop effective release strategies for hatchery-reared juveniles to augment the spawning biomass of Chesapeake Bay blue crabs, which has declined > 80% in 15 years and appears to be recruitment limited.

Population level differences in overwintering survivorship of blue crabs (Callinectes sapidus): A caution on extrapolating climate sensitivities along latitudinal gradients

In a widely distributed, commercially valuable marine decapod, temperature, salinity, size, estuary of origin, and winter duration were important predictors of winter mortality and the results suggest that extrapolation of a Chesapeake Bay based survivorship model to crabs from New York estuaries yielded poor fits.

Identifying future restocking options for Blue Swimmer Crabs (Portunus armatus)

The literature review demonstrated that, in general, portunids are highly fecund, fast growing, short-lived species, with high natural mortalities and are opportunistic predators.

Ionic Requirements of Blue Crabs (Callinectes sapidus) in Environments Containing Low Concentrations of Total Dissolved Solids

It was observed that blue crabs can survive and grow in a simple aqueous solution containing 1 g/l TDS, and this growth is equivalent to that of crabs in 1–8 g/L dilute seawater, which indicates that blue crab culture in inland ponds containing 1 G/L TDS may be feasible.

A Three-Phase Approach to Production of Shedding Crabs (Callinectes sapidus) in Low Salinity Ponds in Mississippi

Simulation results at various stocking densities indicated that production of shedding crabs could be economically feasible and individual culture runs in the current research approached survival rates that would ensure profitability, routine survivorship is currently below the projected estimates necessary to achieve that goal.

Abundance and population structure of the blue crab Callinectes sapidus (Decapoda, Portunidae) in Thermaikos Gulf (Methoni Bay), northern Aegean Sea

The blue crab Callinectes sapidus is an alien decapod established in the Mediterranean Sea. Since 2007, increased abundance has been reported from the northern Aegean Sea sustaining local scale

Assessing the potential for stock enhancement in the case of the Chesapeake Bay blue crab (Callinectes sapidus)

This study suggests ways to improve success of hatchery-raised individuals that can be broadly applied across taxa, and contributes specifically to determining whether large-scale stock enhancement is possible in the case of the Chesapeake Bay blue crab.
