Secondary Production of Macrobenthic Invertebrates from Delaware Bay and Coastal Waters
Abstract Secondary production of benthic invertebrates was estimated for Delaware Bay and coastal Delaware. Production and turnover ratios were highest in Delaware Bay ( P = 46,572 mg AFDW m −2 yr −1 , P:B = 6,O) and progressively lower at two coastal stations ( P = 7,501 to 30,124 mg AFDW m −2 yr −...
