European green crabs have started expanding into Puget Sound here in Washington in recent years. Part of the problem is that some people–such as myself–would happily catch and eat them, but as an invasive species, they’re illegal to catch/possess. I imagine our huge Asian population would also happily eat them. The fish and wildlife department really ought to carve out an exception so that we can all help slow their spread. They have the potential to destroy our native dungeness crab population (the green crabs eat the baby dungeness crabs), which is a huge commercial and recreational fishery.
