Comparative Ecology Of The Parasites Of The Spot, Leiostomus Xanthurus Lacepede, And The Atlantic Croaker, Micropogonias Undulatus Linnaeus (Sciaenidae), In The Cape Hatteras Region, Dennis A. Thoney
Dissertations, Theses, and Masters Projects
Parasite communities of spot, Leiostomus xanthurus, and Atlantic croaker, Micropogonias undulatus, were examined to determine if (1) their structure changed with host age, (2) geographical location affected community structure, (3) food habits affected community structure, and (4) their parasite communities are predictable. Juvenile fish were collected monthly from Chesapeake Bay and Pamlico Sound. Adult fish were collected offshore north of Cape Hatteras in fall, and offshore south of Cape Hatteras in spring and fall. A total of 21 parasitic species occurred in juvenile spot and 19 in juvenile croaker from Chesapeake Bay and Pamlico Sound. The parasite communities of juvenile …
The Influence Of Tributyltin On Various Aspects Of Activation And Reactive Oxygen Formation In Oyster Toadfish (Opsanus Tau) Macrophages, Charles D. Rice
The Influence Of Tributyltin On Various Aspects Of Activation And Reactive Oxygen Formation In Oyster Toadfish (Opsanus Tau) Macrophages, Charles D. Rice
Dissertations, Theses, and Masters Projects
The effects of tributyltin (TBT) on phorbol myristate acetate (PMA)- and calcium ionophore (A23187)-stimulated peritoneal macrophages from oyster toadfish (Opsanus tau) were evaluated in a luminol-dependent chemiluminescence (CL) assay. PMA-stimulated CL responses were increased by in vitro exposure to 50 ug/L TBT, but depressed to baseline values by 500 ug/L TBT. A23187-stimulated CL increased with 5 ug/L and 50 ug/L TBT, and depressed by 500 ug/L TBT. Responses stimulated by synergistic doses of PMA and A23187 were increased by 50 ug/L TBT and depressed by 500 ug/L TBT. Enhanced PMA- and A23187-stimulated CL following TBT exposure returned to baseline values …
