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...

The proximate composition and element contents of claw muscle tissue of Atlantic blue crabs (Callinectes sapidus) were compared with the native warty crab (Eriphia verrucosa) and the commercially edible crab (Cancer pagurus). The scope of the analysis was to profile the chemical characteristics and nutritive value of the three crab species. Elemental fingerprints showed significant inter-specif...

Title of Document: THE EFFECTS OF WATER QUALITY IMPROVEMENTS ON A COMMERCIAL FISHERY: EVIDENCE FROMTHEMARYLAND BLUE CRAB FISHERY Sarah Ball, Ph.D., 2014 Directed By: Associate Professor Doug Lipton, Department of Agricultural and Resource Economics Developing and implementing total maximum daily loads (TMDLs) is a costly and controversial process. However, there are many potential benefits, suc...

In recent years~ severaL species of crab have come under increasing study by scientists. Fluctuations in populations of important commercial species (the blue crab) and the commercial potential of others (the rock crab and deep sea red crab) have led t o this increased attention. But in lab situations, researchers have had problems keeping their specimens alive and healthy for long periods. It ...

The parasitic dinoflagellate, Hematodinium perezi, negatively impacts the commercially important blue crab, Callinectes sapidus. The parasite is a host generalist, but it has not been reported from littoral fiddler crabs living within a few meters of habitat known to harbor infected blue crabs. In the first study, populations of three species of fiddler crab were screened for natural infections...

in this study, some external morphometric characters viz. carapace width (cw) and length (cl), chelar propodus width (chw) and length (chl) and abdominal width (aw) and also body weight (bw) of the blue swimming crab, portunus pelagicus (linnaeus, 1758), were examined. relative growth and regression slope compared among these parameters between 151 males and 158 females. specimens were collecte...
