Data on green crabs collected and trapped from Makah Bay to Coos Bay in 2017.
Data included: Estuary, site, date, sex, carapace width, weight, molt state, estimated year class, missing limbs, collection method and collector.
Overview:
Photographic evidence collected over the past decade indicate that seagrass abundance at Valino Island in South Slough National Estuarine Research Reserve has declined over recent time. Is seagrass wasting disease the culprit, and what are the ecological impacts of reduced seagrass abundance?
The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990’s. After the arrival of a strong year class in 1998, significant recruitment to the populations occurred only in 2005, 2006, 2015, 2016 and 2017. Warm winter water temperatures, high Pacific Decadal Oscillation...
