Evaluating the Effectiveness of Fyke‐Net Sampling to Characterize an Anadromous Rainbow Smelt Population in the Fore River, Massachusetts, USA
Abstract Rainbow Smelt Osmerus mordax are a small anadromous species that is native to the northwest Atlantic Ocean, and their populations have declined rangewide. A small, mid‐channel survey fyke net is annually deployed to collect demographic information on Rainbow Smelt in several rivers in Massa...
