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.

| Abstract: |
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. |
| Purpose: |
To track the presense of Hematodinium within Chionoecetes spp. in the eastern Bering Sea upper continental slope. |

Process Steps
Process Step 1
| Description: |
This dataset contains randomly chosen samples of crab collected from the 2016 NOAA/NMFS/AFSC/RACE groundfish and invertebrate resources bottom trawl survey of the eastern Bering Sea continental slope (EBSS). The survey area extended from Unalaska and Akutan Island to the U.S.-Russian maritime boundary and was divided into six geographic subareas. Each tow is one-half hour in duration with a standard speed of 2.5 knots - exact tow duration and distance fished for each haul can be found in RACEBASE.HAUL. |
|---|
Process Step 2
| Description: |
The sex of the crab is identified (1 = Male, 2 = Female). Individual crab carapaces were measured (± 1 mm), excluding spines, and are reported as size. Shell condition class serves as a semi-quantitative index of molt status and time in shell post-molt. Carapace shell condition was assigned to one of six classes according to specific criteria (0 = premolt or molting, 2 = new hardshell both firm and clean, 3 = oldshell slightly worn, 4 = oldshell worn, 5 = very oldshell). Chela height is measured on right chela at greatest distance (± 0.1 mm) excluding spines. Null or blank fields in data represent no chela height information reported for crab specimen. |
|---|
Process Step 3
| Description: |
Female crab abdomens were evaluated to determine reproductive condition based on the color of the eggs (0 = no eggs, 4 = orange, 9 = no egg color information reported or does not apply), the condition of the eggs (0 = no eggs, 1 = uneyed, 9 = no egg condition information reported or does not apply), and the size of the egg clutch (0 = immature, 1 = mature female no eggs, 2 = trace to 1/8, 3 = 1/4, 4 = 1/2, 5 = 3/4, 6 = full, 9 = no egg clutch information reported or does not apply). |
|---|
Process Step 4
| Description: |
DNA was extracted using modified Ivanova et al. (2006) protocol. Extracted DNA was assayed with two primer sets, targeting either 18S or ITS1 rDNA, to determine presence or absence of Hematodinium spp. Refer to metadata Point of Contact for PCR conditions. PCR Result is identified (0 = negative for Hematodinium DNA, 1 = positive for Hematodinium DNA, 3 = undetermined, at the limit of detection). |
