● Asian Clams are small, averaging less than 1.5 inches and rarely exceeding 3 inches.
● Their shells can either be light green or light brown with distinctive elevated concentric ridges on their shell.
● They were first reported in the United States in 1930, and have since spread to over 39 states.
● These clams are a prolific and highly competitive species, capable of growing fast and spreading.
● Their existence can displace native species, reduce biodiversity, alter the food chain, and damage equipment such as boat mortars, intake pipes, diving gear, and commercial water systems.● Mechanical methods, such as screens and traps can be used.
● Chemical control uses chlorine to kill juvenile clams but can be limited due to chemical restrictions.
● Temperature alteration can also be used in water intake pipes to reduce clam presence.
