A Comparative Study of the Bacterial Flora of the Hemolymph of Callinectes sapidus
The bacterial flora of blue crabs (Callinectes sapid us) from Chesapeake Bay was examined. Hemolymph of normal, healthy blue crabs was found non-sterile, with total bacterial counts ranging from <100 to >3.0 x 10 5 on a seawater-based medium and 0 to >10 5 on Standard Methods Agar. Counts of 0-10 3 were observed on TCBS agar. Vibrio spp., including Vibrio parahaemolyticus, were the major taxono...
متن کاملMolecular indicators of hypoxia in the blue crab Callinectes sapidus
Occurrence of hypoxia in estuarine waters is increasing, and recovery of impacted estuaries is slow. Detection of early effects of hypoxia is needed for timely remedial action to be taken. Here we examine the use of hypoxia-responsive gene and protein expression profiles in the blue crab Callinectes sapidus as early indicators of impacts of hypoxia. We cloned 23 potential hypoxiaresponsive gene...
متن کاملSexual Competition Among Male Blue Crab, Callinectes sapidus.
Experiments and field data on blue crab, Callinectes sapidus, from mid-Chesapeake Bay between 1991 and 1994 were used to test whether large males have advantages over small males in accessing females and in sperm competition. In the field, large males were paired more often, especially with large, more fecund females. However, the variance in the relationship between male and female size in mat...
متن کاملThe Involvement of Hemocyte Prophenoloxidase in the Shell-Hardening Process of the Blue Crab, Callinectes sapidus
Cuticular structures of arthropods undergo dramatic molt-related changes from being soft to becoming hard. The shell-hardening process of decapod crustaceans includes sclerotization and mineralization. Hemocyte PPO plays a central role in melanization and sclerotization particularly in wound healing in crustaceans. However, little is known about its role in the crustacean initial shell-hardenin...
متن کاملThe Influence of Diet Composition on Fitness of the Blue Crab, Callinectes sapidus
The physiological condition and fecundity of an organism is frequently controlled by diet. As changes in environmental conditions often cause organisms to alter their foraging behavior, a comprehensive understanding of how diet influences the fitness of an individual is central to predicting the effect of environmental change on population dynamics. We experimentally manipulated the diet of the...
