Every year for the last 20 years a team of scientists has studied shorebirds and horseshoe crabs of Delaware Bay. We celebrated our 20th year with a workshop on all the work taken place in the last 20years and what comes next. In 2017 the killing of horseshoe crabs continued to prevent restoration while a new threat from oyster aquaculture remains unresolved because state agencies have failed to regulate. Instead they left the conservation of shorebirds and horseshoe crabs up to federal agencies Weather also acted against the crabs, leaving tens of thousands dead after a freak wind storm at high tide. The shorebirds left the bay in poorer condition.
