Crab populations within intertidal eelgrass (Zostera marina) beds were assessed during summertime 2017 (May-August). Data were collected on western Prince of Wales Alaska, at 21 sites. At each site, the coordinates, dates and times that the pots were set and pulled, crab species, and crab size were recorded. Crabs were sampled by setting three replicate strings of baited crab pots for 24-hrs, each with three different pot styles. Fish were sometimes captured, as well, and are reported in this dataset. The purpose of these data was to characterize the crab assemblage within eelgrass communities so that analysis of trophic interactions could be assessed along a gradient of sea otter occupation for an NSF-funded project: Apex Predators, Ecosystems, and Community Sustainability (APECS, http://apecs-ak.org/).
