Demographic data from introduced crab in Seadrift Lagoon 2015 (NCEI Accession 0278283)

browse graphicPreview graphic
This dataset contains biological and survey - biological data collected at Central_CA_Coast during deployment Grosholz_2015 from 2015-02-19 to 2015-12-03. These data include sex, taxon, and taxon_code. The instruments used to collect these data include Fukui fish trap. These data were collected by Catherine de Rivera and Gregory Ruiz of Portland State University and Edwin Grosholz of University of California-Davis as part of the "RAPID: A rare opportunity to examine overcompensation resulting from intensive harvest of an introduced predator (Invasive_predator_harvest)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-01-14.

Supplemental Information
Acquisition Description:
We conducted monthly trapping of invasive European green crabs to gather demographic data in Seadrift Lagoon, Stinson Beach, CA (lat 37.907440 long -122.666169). All sites were accessed by either kayak or by foot via shore entry. At each of six sites, we placed 10 baited traps (folding Fukui fish traps) in shallow (<2 m) subtidal areas. Traps were retrieved 24 hours later and were rebaited and collected again the following day. Trapping was continued for three consecutive days with traps removed on the final day. Each day, data for crab species, size, sex, reproductive condition, injuries, and presence of marks were collected for all crabs in the field. Following data collection, all crabs were returned to the lab, frozen overnight disposed of in commercial agricultural compost.

For each date and site, crabs from all traps (e.g. 10 traps per site) are pooled for counting and measuring.
Traps Used for each date (some with macroalgae "Ulva"):
02/19/2015 10 baited traps + 5 traps with ulva
02/20/2015 10 baited traps + 5 with ulva
03/05/2015 10 baited traps + 5 traps with ulva per site
03/06/2015 10 baited traps + 5 traps with ulva
03/24/2015 10 traps/site
04/08/2015 10 traps/site
04/15/2015 10 baited traps + 4 traps with ulva
04/24/2015 10 traps/site
