Habitat use of American eel (Anguilla rostrata
) in a tributary of the Hudson River, New York

Abstract.—Hudson River tributaries serve as spawning areas for substantial numbers of anadromous and potamodromous fishes, and are critical habitat for at least alewife Alosa pseudoharengus, sea lamprey Petromyzon marinus, white sucker Catostomus commersonii, and smallmouth bass Micropterus dolomieu. Those species that are resident in tributary mouths are often common, widespread taxa in the Hudson River system but they are rarely present in large numbers. We document high densities of American eel Anguilla rostrata in one tributary mouth (>13,000 eels/ha; 15–30 g/m2) and present observations supporting that this is typical of Hudson River tributaries. We suggest that the biology of American eel substantially determines the structure of the fish community and energy flow within these habitats. The presence of barriers and high density eel populations limit the import of marine and estuarine nutrients into Hudson River tributaries.

Electron Microanalysis

The Hudson River commercial striped bass (Morone saxatilis) fishery has been closed since 1976 due to high polychlorinated biphenyl (PCB) contamination. Accurate forecasting of PCB levels in striped bass has been confounded by high variance in contamination among individuals. We investigated the relationship between habitat use and PCB contamination in Hudson River and Long Island Sound striped bass using electron microanalysis of otolith strontium to generate time series of individual salinity habitation. Males with highly contaminated levels (mean PCB = 8.3 ppm) showed freshwater resident behavior, rarely experiencing salinities >5 ppt. Several individuals showed large habitat shifts. Shifts from brackish or marine habitats to freshwater habitats were often associated with high PCB levels. A third pattern was apparent in large females, where polyhaline/euhaline salinity habitation was associated with lower PCB levels. Total PCB body burden was inversely correlated with mean salinity encountered during the most recent growth season prior to capture. Fish with recent exposure to polyhaline salinities showed high variability in PCB body burdens (0.4-9.0 ppm), suggesting a local source of PCB contamination in the New York Harbor region.

The Relationship

In the first half of the 19th century scientific philosophers in the United States, such as Emerson and Thoreau, began to pursue the relationship between man and nature. Painters from the Hudson River School discovered the rural spaces to the north of New York and began to celebrate the American landscape in their paintings. In many places at this time garden societies were founded, which generated widespread support for the creation of park enclosures While the first such were cemeteries with the character of parks, housing developments on the peripheries of towns were later set in generous park landscapes. However, the centres of the growing American cities also need green spaces and the so-called «park movement»reached a first high point with New York's Central Park. It was not only an experimental field for modern urban elements, but even today is a force of social cohesion.
