Investigations of Day-Night Distributional Changes of Striped Bass in Hudson River Interpier Areasby John A. Tiedemann, New Jersey Marine Sciences, Consortium, Sandy Hook, NJ, USA,
Abstract: As part of a Hudson River fisheries study, investigations were made in an attempt to assess whether onshore-offshore movements could change the number of juvenile striped bass using interpier areas along the Manhattan waterfront during the day or at night. In an attempt to determine the presence, or absence, of striped bass in these interpier areas a series of bottom trawl surveys was conducted along the shoreline from New York Pier 59. Without exception, trawls conducted during the day produced higher numbers of fish and higher numbers of striped bass than trawls conducted at night. The consistently higher daytime catches of striped bass indicate that some sort of onshore-offshore movement was occurring in these interpier areas.
