Distribution of Juvenile Horseshoe Crabs in Subtidal Habitats of Delaware Bay Using a Suction-Dredgeiculties with sampling in this habitat. A suction-dredge was constructed consisting of a “T”-shaped sampling head; an 8-hp trash pump, a 15.2-m-long non-collapsible hose-pipe; and a gunwale-mounted catch-basin to survey newly hatched juvenile horseshoe crabs in shallow subtidal habitats of lower Del窗帘等 发表于 2025-3-24 18:27:03
