Canada V9V 1N8 david.welch@kintama.com File list: Tags_metadata.csv Detections_data.csv Detection_efficiency_69kHz.r Detection_efficiency_180kHz.r Count_detections.r Survival_using_180kHz_tags.r generate_capture_histories.r util.r Instructions: It is simplest to put all files into a single working directory for all R scripts to work. In addition to the packages listed at the top of the R scripts, Program Mark must be installed to run Survival_using_180kHz_tags.r (http://www.phidot.org/software/mark/rmark/). See publication for detailed analytical methods. File descriptions: Tags_metadata.csv-- each row represents a steelhead smolt from Seymour River hatchery that was acoustic-tagged in 2015. fish_id=concatenation of the 69 kHz and 180 kHz codes transmitted by the acoustic tags implanted into this inidividual; code_label_69 and tag_id_69=identification codes transmitted by the V9 69 kHz tags; code_label_180 and tag_id_180=identification codes transmitted by the V4 180 kHz tags; fl=fork length in mm; weight=fish weight in air in g; treatment_type=not populated; utc_release_datetime=date and time the tagged fish were released in universal coordinated time yyyy-dd-mm hh:mm:ss. Detections_data.csv-- each row represents a recorded transmission from an acoustic tag implanted into a steelhead smolt from Seymour River hatchery in 2015. tag_id and code_label= unique identification codes transmitted by the tag; receiver_sn= serial number of the receiver that recorded the transmission; detection_datetime= date and time the detection was recorded in universal coordinated time yyyy-mm-dd hh:mm:ss; subarray= name for the group of receivers deployed at the same general location (see Figure 2 in publication for map); subsubarray= adds detail to subarray name; position= for subarrays deployed in lines, this is a numerical position from east to west or south to north; kintama_nickname= a shortened name the receiver subarray and position; final= direction of migration; tag_type= tag implated (V9-1H or V4-1H); utc_release_datetime=date and time the tagged fish were released in universal coordinated time yyyy-dd-mm hh:mm:ss; tag_id2= unique identification code transmitted by the other tag implanted into this individual; fish_id=concatenation of the 69 kHz and 180 kHz codes transmitted by the acoustic tags implanted into this inidividual. Detection_efficiency_69kHz.r-- R script that calculates the detection efficiency of the 69 kHz V9 tags implanted into steelhead smolts from Seymour River hatchery in 2015. Detection_efficiency_180kHz.r-- R script that calculates the detection efficiency of the 180 kHz V4 tags implanted into steelhead smolts from Seymour River hatchery in 2015. Count_detections.r-- R script that counts the number of detections of each tag recorded at the Discovery Islands subarray and its component south and north subsubarrays. Survival_using_180kHz_tags.r-- R script that provides empicial estimates of the conficence intervals on the survival estimates that would have been obtained had fish been tagged only with V4 180 kHz tags and had exited the study area prior to tag expiry (i.e. as in a regular study). generate_capture_histories.r-- R function that generates a simulated frequency distribution for all possible capture histories and returns a data frame that can be passed to RMark. util.r-- R function called from generate_capture_histories.r
