Mean catch per swept area (CPSA) and relative abundance, which normalizes mean CPSA on a 0-1 scale based on the minimum and maximum values for each species & season of fish species in U.S. Atlantic for the Northeast Regional Habitat Assessment (NRHA) using the 2010-19 survey data. The hexagons are color-coded by relative abundance.<\/SPAN><\/P>
