Structured habitat provides a refuge from blue crab, Callinectes sapidus, predation for the bay scallop, Argopecten irradians concentricus (Say 1822)
Predation in estuarine systems is an important source of mortality for benthic organisms. In laboratory mesocosm experiments, we assessed the survival of bay scallops (Argopecten irradians concentricus) of various sizes (10–19mm, 20–29mm, 30–39mm, and 40–50mm shell height; SH) as a function of femal...

| description | Predation in estuarine systems is an important source of mortality for benthic organisms. In laboratory mesocosm experiments, we assessed the survival of bay scallops (Argopecten irradians concentricus) of various sizes (10–19mm, 20–29mm, 30–39mm, and 40–50mm shell height; SH) as a function of female blue crab, Callinectes sapidus, predation as it varied with habitat (oyster shell, sand, Gracilaria spp.) and predator size (>140mm, ≤140mm carapace width; CW) in a balanced two-by-three factorial design. Scallops of all sizes were afforded higher proportional survival with small female crabs (0.61, SE=0.05) compared to that with large female crabs (0.36, SE=0.05), and the proportion of scallops surviving was highest in oyster shell (0.61, SE=0.08), as compared to the Gracilaria spp. and sand treatments, at 0.41 (SE=0.06) and 0.42 (SE=0.07), respectively. Subsequent field-tethering experiments conducted in the Lynnhaven River sub-estuary of the lower Chesapeake Bay further illustrated the effect of habitat on the survival of juvenile bay scallops ( |
