Biophysical Mechanisms of Larval Fish Ingress into Chesapeake Bay
Selective tidal stream transport is hypothesized as a dominant mechanism by which larvae of marine animals move through estuarine openings. For larvae moving from the shelf to estuarine habitats, selective tidal stream transport proposes that larvae are higher in the water column during flood tide and lower in the water column during ebb tide. Although a number of studies conclude that selectiv...
متن کاملPatterns of Larval Atlantic Croaker Ingress into Chesapeake Bay, USA
We compared ingress patterns of Atlantic croaker Micropogonias undulatus larvae into Chesapeake Bay, USA, with published ingress patterns through barrier island inlets, the accepted model for larval fish ingress. This model asserts that larvae ingress on night flood tides at the flooddominated side of the inlet and at all depths. At the Chesapeake Bay mouth and in the adjacent coastal waters, w...
متن کاملMycobacteria as Environmental Portent in Chesapeake Bay Fish Species
Infection with environmental mycobacteria is increasing among many Chesapeake Bay fish species. Prevalence in juvenile Atlantic menhaden differed between tributaries and ranged from 2% to 57%. Mycobacterial infection may be a syndromic sentinel of altered environmental conditions that threaten aquatic animal health.
متن کاملI – Recent Fish Health Issues in the Chesapeake Bay Watershed
A northern snakehead Channa argus population was documented within a 23km reach of the tidal freshwater Potomac River and associated tributaries in 2004 when 20 snakeheads were collected with several gears including hook-and-line and electrofishing. An additional 271 snakeheads were collected in 2005 primarily with various electrofishing gears. Boat electrofishing mean catch rate increased from...
متن کاملTransition metal-binding proteins from three Chesapeake Bay fish species.
Three species of Chesapeake Bay fish were collected, and endogenous levels of metal binding protein (MBP) were determined. In addition, the induction of metal-binding proteins by cadmium was studied. Livers from freshly caught fish were extracted and chromatographed on Sephadex G-75 to resolve MBP in the 5 to 20 kdalton range. All species studied exhibit measurable but varied levels of endogeno...
