Abstract
Habitat deterioration is consistent with perceived population declines for several resident and anadromous finfish species in Chesapeake Bay that are subjected to different levels of fishing pressure (e.g., striped bass versus blueback herring). Diminution of habitat quality has natural and anthropogenic roots that are difficult to separate. Recent contaminant effects studies focused on Chesapeake Bay fishes can be grouped as follows: (a) mathematical and statistical modeling studies aimed at elucidating contaminant and stock trend relationships using extant data and theoretical insights, (b) biological and chemical field surveys in selected areas to demonstrate spatio-temporal associations between levels of toxic organic and inorganic chemicals and absence or reduction of sensitive species, (c) measurements of condition factors and tissue residues of chemical contaminants in juvenile and older fishes, (d) laboratory studies of life stage and species sensitivities to an array of toxic contaminants, and ( e) in-situ field studies designed to measure the effects of habitat quality on specific life stages of selected species.
