AFSC/RACE/SAP/Pathobiology: 2016 Bitter crab disease prevalence in Chionoecetes spp. from eastern Bering Sea upper continental slope

AFSC/RACE/SAP/Pathobiology: 2016 Bitter crab disease prevalence in Chionoecetes spp. from eastern Bering Sea upper continental slope

This dataset contains crab data from a field survey of Chionoecetes spp. collected during the 2016 NOAA/NMFS/AFSC/RACE groundfish and invertebrate resources bottom trawl survey of the eastern Bering Sea continental slope (EBSS). Crabs were taken opportunistically, at any station regardless of location and depth, and at random. Blood samples were taken from collected crab using non-lethal methods and were preserved in 100% ethanol. Samples were tested in a laboratory with a DNA test to detect the presence of the parasite Hematodinium sp., the causative agent of Bitter Crab Syndrome (BCS). The data includes sampling year, sampling station information, species, crab morphometrics, Hematodinium sp. parasite presence/absence based on PCR assay results.
