Would you eat invasive species if it helped protect your local environment?

Fishermen have begun catching invasive European green crabs to create a new commercial seafood product. By harvesting the destructive species, they hope to mitigate its impact on coastal eelgrass beds and native shellfish populations.

Why it matters

Green crabs are an invasive species that cause significant economic damage to the shellfish industry by outcompeting native crabs and lobsters. Promoting their consumption serves as a dual-purpose strategy to lessen their ecological threat while supporting fishermen.

A female green crab releases up to 185,000 eggs per spawning, while Washington state allocated over US$38 million for eradication through 2027. Market prices currently range from US$0.08 for hard-shell crabs to US$3 for soft-shell specimens.

The players

Washington state

This state government declared a green crab emergency and has allocated over US$38 million for eradication efforts.

Massachusetts

This state provides fishermen an incentive of US$0.40 per pound to catch green crabs and supports culinary innovation.

The details

Fishermen identify crabs that are about to shed their hard shells and place them into specialized tube networks in lobster crates to await moulting. This process creates the more valuable soft-shell crab, which chefs are increasingly using in culinary applications as restaurant offerings have grown 10-fold since 2021.

In 1978, Maine soft-shell clam landings exceeded 3.6 million kilograms.
Advocates began observing a growth in restaurants offering green crab in 2021.
Washington state declared a green crab emergency in 2022.
By 2025, Maine soft-shell clam landings had dropped to 572,644 kilograms.
Nearly two million green crabs were caught in Washington state in 2026.

Culture Shift

This culinary trend represents a shift toward using invasive species as a sustainable food source, mirroring broader environmental efforts to manage ecosystems. This approach moves beyond traditional eradication, positioning the consumption of these crabs as a viable method to support local biodiversity.

Consumers may start seeing soft-shell green crab appearing on more restaurant menus as a result of these harvesting efforts. These options provide a way for diners to directly participate in supporting coastal ecosystem restoration through their own purchasing decisions.

The takeaway

Incorporating invasive species into the food supply chain can transform a destructive environmental threat into a valuable economic resource. By choosing to eat these crabs, consumers can help protect native habitats like salt marshes and eelgrass beds.
