Forage Fish – Open Water/NY and CT Coastlines

The forage indices measures the productivity of small fish in the Sound, which is the basis of the food supply for larger fish, including game fish. View Indicator

Finfish Biomass and Species Richness Indices

Fish biomass indicates the productivity of the Long Island Sound fishery. Species richness measures the diversity of species supported within the Sound's various habitats. View Indicator

Invertebrate Biomass Index

Invertebrate biomass is an indicator of the productivity of the Long Island Sound. View Indicator

Game Fish

The abundance of game fish is a reflection of the productivity of Long Island Sound and the effectiveness of coast-wide fishery management plans that seek to stabilize populations while maximizing harvest opportunities. View Indicator

Shad & River Herring—Long Island Sound

Abundance of American shad and blueback herring, as reported in the Long Island Sound Trawl Survey. View Indicator
