Shellfish aquaculture farms as foraging habitat for nearshore fishes and crabs

<p>This is the dataset used for the analysis in&nbsp;our paper. The file contains species counts and behavior classifications of nearshore fish and crabs taken from time-lapse underwater video. Also included are habitat transect data from each site. Presence/absence of zostera marina and zostera japonica eelgrass, algae, as well as eelgrass metrics were quantified in the transects.</p> <p>The metadata spreadsheet contains descriptions&nbsp;of each column in the datasheet.</p> <p>This data was collected at shellfish aquaculture farm sites across Puget Sound, Washington, USA in 2017, 2018, and 2019 using underwater timelapse video cameras and habitat transects.</p> <p>Transects were done with 1/4 meter^2 quadrat divided into 25 10x10cm^2 squares, each quadrat was measured 5 times along a 30 meter line parallel to shore.</p> <p>Video was recorded in 2 minute lengths every 10 minutes starting 1 hour before high tide, going to 1 hour after high tide,&nbsp;using cameras positioned approximately 18 inches off the substrate. PVC stakes were used to mark a 1 meter square of camera visibility and organisms observed within that 1 meter square were recorded.&nbsp;</p> <p>For more information, see my chapter 1 thesis.</p>
