Importance Of Predation By Crabs And Fishes On Benthic Infauna In Chesapeake Bay, Rw Virstein
Importance Of Predation By Crabs And Fishes On Benthic Infauna In Chesapeake Bay, Rw Virstein
VIMS Articles
The significance of large motile predators in controlling the distribution and abundance of the macrobenthic invertebrates within the sediments (the infauna) in a shallow subtidal sand community was tested using manipulative field experiments. The blue crab (Callinectes sapidus) and 2 species of bottom—feeding fishes, spot (Leiostomus xanthurus) and hogchoker (Trinectes maculatus), were either excluded from or confined to small areas using wire mesh cages. Callinectes and Leiostomus effectively reduced infaunal desnities; Trinectes did not. The infauna responded to decreased predation with a large increase in density and diversity within 2 mo. The large population increases were exhibited by opportunistic species, …

Assessment Of Surf Clam Stocks In Nearshore Waters Along The Delmarva Peninsula And In The Fishery South Of Cape Henry, Joseph G. Loesch
Assessment Of Surf Clam Stocks In Nearshore Waters Along The Delmarva Peninsula And In The Fishery South Of Cape Henry, Joseph G. Loesch
VIMS Articles
In 1974 the abundance of surf clams was sampled from Delmarva Peninsula, Delaware south to North Carolina. Surf clams were not found in commercial densities in the inshore waters along the Delmarva Peninsula. Off shore and south of Cape Henry, an area of intense surf clam fishing, the estimated standing crop was IO million bushels. A length-age relationship was estimated and it implies that recruitment to the fishery occurs at approximately age 2, at an average annual rate of about 8%. It is concluded that because of the low recruitment rate relative to the heavy fishing pressure that Virginia surf …
