Detailed Description
Fish collection streams (n= 1,196) for 57 species within the Chesapeake Bay watershed (black outline).

A regional assessment of fish health in the Chesapeake Bay watershed
Fish diseases in freshwater ecosystems pose significant ecological and socioeconomic challenges; yet, monitoring them in wild populations is complex due to interactions between pathogens, hosts, and environmental conditions. External DELT (deformity, erosion, lesion, tumor, and parasite) data (fig. 1) provide a rapid and broad measure of fish health but are a relatively coarse indicator that...
