ALBANY, N.Y. — New York is using clams and oysters to combat harmful algae threatening coastline ecosystems.

Governor Andrew M. Cuomo has announced $2 million in funding to support research on Long Island that would increase clam and oyster populations to fight brown tide.

Brown tide occurs when certain phytoplankton (FIGH’-to-plankton) species grow to high concentrations and color the water brown along the eastern coast of Long Island.

The condition can decrease the amount of sunlight that penetrates the water and limits survival of other plants and algae.

Clam and oyster populations have been shown to filter and improve water quality. The money would go toward seeding programs and other initiatives at Stony Brook Research Center in ocean health research.
