Testing the efficiency of different sweep types on fishing nets was the focus of twin trawling operations August 18-28 aboard the F/V Karen Elizabeth from Point Judith, RI. The target species: summer flounder, with red hake and winter flounder a secondary priority. Summer flounder, also known as fluke, is a flatfish that tends to stay on the ocean bottom. A valuable commercial and recreational fishery, it is found in offshore waters in the winter and in inshore waters throughout the summer.
