Abundances, size-frequency distributions, sexual composition and molt-stage composition of blue crabs Callinectes sapjdus were measured during 1983 to 1985 in the Rhode River, a subestuary of central Chesapeake Bay, USA. Crabs at the mouth and head of the river basin were sampled with monthly triplicate otter trawls. Crabs in the principal tidal creek of the river were sampled 3 d a week with a fish weir, which caught crabs moving upstream and downstream separately. Crabs exhibited consistent, marked seasonal cycles in abundance as well as considerable annual variation in July peak abundances. New recruits entered the subestuary in late fall …

A Multispecies Aggregation Of Cirrate Octopods Trawled From North Of The Bahamas, Michael Vecchione
A Multispecies Aggregation Of Cirrate Octopods Trawled From North Of The Bahamas, Michael Vecchione
VIMS Articles
Two cruises in the western North Atlantic collected 38 trawl samples between the Bahamas and New England. Of the 22 cirrate octopods taken in these samples, 17 came from the area north of the Bahamas. Pooled catch rate (specimens per hour of bottom trawling time) was significantly higher north of the Bahamas than in any other area sampled. Although the taxonomy of these gelatinous benthopelagic cephalopods is not yet settled, morphological characters from these specimens indicate that this aggregation includes at least four species. Only one species (Cirrothauma murrayi) was widely distributed in these samples.

Research has been carried out on sea turtles in Chesapeake Bay and adjacent waters since 1979. Chesapeake Bay supports populations of juvenile loggerhead, Caretta caretta (Linnaeus) and Kemp's ridley, Lepidochelys kempi (Garmon) sea turtles during summer. Data from our aerial surveys and biotelemetry studies show that turtles migrate northward from south of Cape Hatteras and enter the Bay during spring. We estimate between 2000 and 10,000 loggerheads utilize the Bay during summer, where they forage for abundant invertebrate fauna. Fifty to 200 sea turtles strand dead on shore each year. At least one-third of the deaths are attributable to human …
