Managing a fishery starts with assessing the abundance and types of fish in the sea. For more than 25 years, the Connecticut Department of Energy and Environmental Protection (CTDEEP) has conducted a trawl survey throughout the Sound to track the size of fish populations. On each trawl, the crew of the research vessel John Dempsey works quickly and precisely to count, weigh, and measure finfish and invertebrates before returning them to the water and moving on to the next site. The samples enable resource managers to compare year to year the relative abundance of dozens of species living in Long Island Sound’s varied habitats.
