Abstract: European green crab, Carcinus maenas, trapped and collected in coastal Oregon and Washington coastal estuaries during the 2019. Data for individual crabs include: estuary, site, date of collection, sex, carapace width, weight, molt stage (color of abdomen), missing limbs, estimated year class, method of collection, and name of collector. This dataset has been re-coded for a standardized organization of carapace colors of the Carcinus maenas. 4. Date of data collection: 20190101-20201231 5. Geographic location of data collection: Grays Harbor, Willapa Bay, Tillamook Bay, Netarts Bay, Yaquina Bay, Coos Bay, 6. Funding sources that supported the collection of the data: Sylvia Yamada was primarily self-funded, but received travel funds from Pacific States Marine Fisheries Commission. For other sources, see acknowledgements in the 2019 green crab report. 7.

New data collected during the year 2020 was also included in the SimsDatasetMNR and can be found in the 2020 version soon to be archived. -------------------------- METHODOLOGICAL INFORMATION -------------------------- A description of the methods used for collection analysis and processing of data, and the environmental conditions under which the data were collected, can be found in the 2019 green crab report. The dataset was reviewed, and quality controlled by Sylvia Behrens Yamada, Shon Schooler and Clara Llebot. 1.

File List A. Filename: SimsDatasetMNR.csv Short description: Carapace width and re-coding of missing limbs and carapace color of crabs during trapping or oyster handling in Oregon estuaries and Willapa Bay and Grays Harbor Washington. All green crab reports from 2002 to 2016 have the individual crab data, such as carapace width, included as a table within the annual reports. Individual crab data from 2017 to 2019 were too numerous to include in the annual reports and thus were tabulated in accompanying data files. All the reports and data files are deposited in ScholarsArchive@OSU Green Crab Collection: https://ir.library.oregonstate.edu/collections/hd76s578s ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: SimsDatasetMNR ----------------------------------------- 1. Number of variables: 23 2. Number of cases/rows: 8975 3. Missing data codes: Sex 0= too small to sex; N/A = Sex not recorded. Width(mm), N/A = carapace was damaged or was not measured Weight(g), N/A = crab was not weighed Color, N/A = color of abdomen was not recorded Est. Year Class, N/A = not estimated Missing limbs, N/A missing limbs not noted Comments, 0 = no comments Trap Type, N/A = no trap was used. Crabs found while handling oysters 4. Variable List A. Estuary: Coos, Yaquina, Netarts, Tillamook, Willapa, Grays Harbor B. Site: name of study site within an estuary C. Year: 2019 D. Month: 1 (January) to 12 (December) E. Day: 1 to 31 F. Sex: M = male; F = female; 0 = too small to determine: N/A = not determined G. Width(mm) = Carapace Width in mm: maximum distance, as measured from 5th spine to 5th spine. Size was estimated as 30-40 mm in Bone River samples from Willapa Bay. H. Weight(g): wet weight of live crab measured in grams; N/A = no scales were available I. Color = color of abdomen: g, gr or green (newly molted); y or yellow; o or orange; r or red (close to molting); N/A or blank = not noted J. Est. Year Class: estimated year that larva settled from the plankton and metamorphized into a miniature crab. With 5 overlapping year classes it is not always possible to estimate year classes; N/A = not determined K. Missing Limbs: R = crab's right claw; L= crab's left claw: 1= claw, 2, 3, 4, 5 =last limb; r = regenerating limb; e.g. rL1 = left claw is regenerating; 0 =no missing limbs, N/A =not noted (Several N/A were entered incorrectly instead of using Ò0Ó and were therefore re-coded for Sims capstone project) L. Comments: additional information, presence of barnacles, soft = newly molted, eggs = female with eggs, maturity of small females: mature=abdomen can be lifted, immature =abdomen is attached, 0 = no comments M. Trap type: Fukui fish traps; Minnow = crayfish traps; pitfall traps at Stackpole = 5 gallon buckets, pitfall traps at other site = coffee cans; recreational crab rings; hand caught; gill nets, oyster seed pallets, oyster storage bins, tubs, N/A = not caught in trap, found while harvesting oysters. N. Collector: Name of person finding or reporting trapping data or crab sighting -----------------------------------------
