Underwater Videographic Observations of Cultured Delta Smelt in Field Enclosures: Video Clips and Summary Data

All data is part of a pilot study aimed to observe Delta Smelt behavior within enclosures deployed in the wild. The enclosures used were designed by The California Department of Water Resources and UC Davis as part of their ongoing Delta Smelt enclosure deployment studies. Study 1: This data includes 16 17:43 minute videos of observations of Delta Smelt behavior in a floating field enclosure and an associated .csv file with data generated from the video clips. The videos were recorded using a Gopro Hero 4 Black digital action camera in a field enclosure located in a controlled agriculture pond at the University of California, Davis’ Center for Aquatic Biology and Aquaculture (CABA), Putah Creek Facility, Davis, California, between September 10 and 18, 2019. The data file contains information on the occurrence and duration of alarm behaviors exhibited by Delta Smelt. Four cameras were mounted to the interior of the enclosure at approximately mid height of the enclosure. Viewing area of the cameras extended from approximately the midpoint of the cage bottom to about halfway up the adjacent wall. A video began recording approximately 10 minutes prior to the simulated cage visit and recorded until battery failure resulting in 4, 17:43 minute videos per event. After 17:43 minutes the GoPro camera recorded footage as a separate video file, however they are still part of the same sampling event. Videos were recorded by one camera at a time and consecutive recordings alternated between cameras. Study 2: This data includes 59 10-min video clips of observations of Delta Smelt behavior in a floating field enclosure and an associated .csv file with data generated from the video clips. The videos were recorded using a Gopro Hero 4 Black digital action camera in a field enclosure located in the Sacramento River near Rio Vista, California, between October 12, 2019 and November 2, 2019. The data file contains information on the occurrence and duration of alarm behaviors exhibited by Delta Smelt and the occurrence, duration, and intensity of three types of disturbances: boat noises, noises associated with physical disturbances to the enclosure (e.g., clanking, rattling and banging of the enclosure), and vertical movements of the enclosure associated with wave activity. Two cameras were mounted to the interior of the enclosure at approximately mid height of the enclosure. Viewing area of the cameras extended from approximately the midpoint of the cage bottom to about halfway up the adjacent wall. A video clip of 10-min in duration was recorded at intervals of every 120 min between the hours of 09:00 to 18:00 from 12 October to 02 November 2019. Videos were recorded by one camera at a time and consecutive recordings alternated between cameras.
