Maryland Offshore Wind Farm Could Become Stop-Over Region for Migrating Fish
Phoenix666 writes:
For the endangered Atlantic sturgeon and the commercially and recreationally important striped bass, the Delaware-Maryland-Virginia coastal shelf serves as an important spring and fall "flyway." Typically thought of as an established aerial route used by migratory birds to travel between feeding and breeding grounds, a recent study by scientists at the University of Maryland Center for Environmental Science applies the term to fish species of concern. Authors suggest that the development of wind farms on the Delmarva coastal shelf, 17-26 miles from Ocean City's shoreline, may alter the migratory behavior of these fish as new wind turbines in this otherwise featureless region could create habitat around which fish linger.
[...] Scientists also deployed 20 acoustic receivers in the Maryland Wind Energy Area. When a tagged fish swims past a receiver, a listening device about the size of a liter soda bottle, the receiver records the "ping" sent out by the tag. Each "ping" transmits its unique ID and the depth at which the fish was swimming to the receiver, which also records the time and date. The array of receivers allows scientists to monitor the movements of tagged fish. During the study, "pings" from 352 individual Atlantic sturgeon and 315 individual striped bass were recorded by receivers.
Scientists believe that Maryland's future offshore wind farm could become a stop-over region where striped bass and sturgeon might linger longer. The DelMarVa coastal shelf is a fairly barren area. The development of high relief wind turbines would provide structure around which fish may gather and linger during migrations.

If the data pans out, the offshore wind farms can do double duty as a power source and wildlife refuge.
