Use of ocean and estuarine habitats by young-of-year bluefish (Pomatomus saltatrix) in the New York Bight
Young-of-year (YOY) blue-fish (Pomatomus saltatrix) along the U.S. east coast are often assumed to use estuaries almost exclusively during the summer. Here we present data from 1995 to 1998 indicating that YOY (30–260 mm FL) also use ocean habitats along the coast of New Jersey. An analysis of histo...
