Estuarine Ingress of the Blue Crab Callinectes Sapidus
… investigated ingress of postlarval blue crabs Callinectes sapidus to the Newport River estuary, North Carolina, USA. Data from C. similis, Menippe mercenaria, Pachygrapsus transversus, and Arenaeus cribrarius are included in some chapters for comparison. Changes in tolerance to low salinity …

Anaerobic/aerobic pretreatment of blue crab (Callinectes sapidus) cooker wastewater
Wastewater from the pressure cooking of blue crabs presents a difficult treatment challenge. COD concentrations in the range of 15,000 to 30,000 mg/L are found in this wastewater, with TKN concentrations above 2,000 mg/L. Direct discharge of the wastewater, which is currently allowed, adds …

Instrumental Methods for Determining Quality of Blue Crab (Callinectes sapidus) Meat
The purpose of this study was to find an alternative instrumental method to sensory analysis and to further investigate the aroma properties of spoiling blue crab meat. This was accomplished by use of a Cyranose 320™ Electronic Nose, Draeger-Tubes®, and solid-phase microextraction gas …

Characterization and treatment of wastewater from blue crab (Callinectes sapidus) processing facilities
The process wastewater from three blue crab processing plants in Virginia was characterized. Most of these effluent streams were highly concentrated. For example, the retort water from the cookers exhibited the following concentrations: BOD₅ = 14,000-29,000 mg/L, TSS = 650-6,200 mg/L, TKN-N = …

A technology analysis of the U.S. Atlantic blue crab (Callinectes sapidus) processing industry
The dehydration rates of crabs during low temperature storage and various cooking processes were determined. Season, cooking time, and cooking method significantly affected the weight loss of crabs. The thermal energy (F250 ) crabs received during a commercial cooking process was evaluated by …

Abundance and Distribution of Early Life Stage Blue Crabs (Callinectes sapidus) in Lake Pontchartrain
… in the abundance of early life stage blue crabs (Callinectes sapidus). Collections were made using a 1 m2 throw trap and data showed that C. sapidus numbers varied over time and among sites. Two recruitment events occurred during the study. During the first recruitment in May-June, C. sapidus …

Sub-Lethal Effects of Hypoxia/Hypercapnia on Callinectes Sapidus in the York River Estuary, Virginia
… effects of hypoxic environments on blue crabs, Callinectes sapidus in an estuarine environment. Hypoxic conditions were treated as a multiple stressor involving low dissolved oxygen (D.O.), increased carbon dioxide (hypercapnia), and low pH concurrently. The objectives were to: 1) identify …

Detection, activity and resistance to thermal inactivation of peroxidase in the blue crab (Callinectes sapidus)
Peroxidase is one of the most heat resistant enzymes and may cause undesirable quality changes in thermally processed foods. Peroxidase activity and its resistance to thermal inactivation in fresh and pasteurized lump, claw and flake meat of both male and female blue crabs was determined …

Feasibility study for packaging and pasteurizing meat of the blue crab, Callinectes sapidus, in retort pouches
The purpose of this research was to determine the feasibility of pasteurizing crabmeat in retort pouches compared to cans. Retort pouches and cans were packed with various amounts of crabmeat, pasteurized to an internal temperature of 185°F (85°C) for 1 min, and subsequently cooled. The criteria …

Linkages between Marsh Fragmentation, Prey Availability, and Blue Crab (<i>Callinectes sapidus</i>) Abundance and Mortality
… newly created open water areas. Blue crabs, <em>Callinectes sapidus</em>, use both marsh edge and SAV habitat during the juvenile stages and support one of the largest fisheries in the Gulf of Mexico, worth over $70 million in 2015. This thesis studied the linkages between habitat type, SAV …

Sodium and glucose transport across the in vitro perfused midgut of the blue crab, Callinectes sapidus Rathbun
… across the midgut as well as the hindgut of Callinectes sapidus and the functioning of these two regions of the gut in osmotic and ionic regulation of the animal, and (2) to elucidate the mechanism of glucose absorption across the midgut of C. sapidus and to assess its role in nutrient …

Effects of high hydrostatic pressure processing on Bacillus cereus spores in fresh blue crab meat (Callinectes sapidus)
The Food and Drug Administration has recently expressed concern for the safety of seafood and seafood products. One of the concerns is the presence of Bacillus cereus in fresh blue crab meat. Bacillus cereus is a spore-forming pathogen whose spores survive the customary thermal treatments applied …

Recruitment of Blue Crab, <i>Callinectes sapidus,</i> Postlarvae to the Back-Barrier Lagoons of Virginia's Eastern Shore
… on the early life history of the blue crab, Callinectes sapidus, has been conducted in large partially stratified estuaries such as the Chesapeake Bay. In contrast, little is known about the recruitment dynamics or habitat requirements of blue crab postlarvae (megalopae) in shallow well-mixed …

The Effect of Thermal Processing Schedules and Unit Operations on the Quality of Blue Crab (Callinectes sapidus) Meat
… on the microbiological quality of blue crab (Callinectes sapidus) meat were determined in a commercial crab processing facility. Thermal processing was evaluated at 5, 7, and 8 minutes at 250ï °F for the destruction of microorganisms, including Listeria monocytogenes. F-values calculated …

Changing Fecundity and Reproductive Output in Females of a Chesapeake Bay Population of Blue Crab, <i>Callinectes sapidus</i>
<p>The Chesapeake Bay blue crab, <em>Callinectes sapidus</em>, is an important species both ecologically and as a fishery. Fishery dependent and independent data indicate that the population declined abruptly in the mid-1990s and has remained low. Previous work prior to the decline in population …
