(1) Project description:

We provide adult cisco (Coregonus artedi) catch data and output from juvenile cisco multistage time-to-event survival modeling for restoration assessment. We also provide a program R script for demographic analysis and population viability analysis for the reintroduced cisco population in Keuka Lake, New York, USA.

DATA FILE 1: MCMC samples from multistage juvenile survival analysis mcmc_samples.rds

Study years: 2019-2021 Location of data collection: Keuka Lake, New York, USA

Description: This .rds file contains an R object of the MCMC output (a list of three MCMC chains) from the top-ranked multistage time-to-event model to estimate juvenile cisco survival in Keuka Lake. 

An acoustic telemetry study of hatchery-reared juvenile Cisco was conducted following acoustic transmitter implantation procedures by:

McKenna Jr., J.E., et al. 2021. "Acoustic tag retention and tagging mortality of juvenile cisco Coregonus artedi." Journal of Great Lakes Research 47(3): https://doi.org/10.1016/j.jglr.2021.03.020.

Time-to-event data was collected and analyzed via a whole-lake acoustic telemetry experiment described by:

Koeberle, A.L., et al. 2023. "Whole-lake acoustic telemetry to evaluate survival of stocked juvenile fish." Scientific Reports 13: https://doi.org/10.1038/s41598-023-46330-6.

We fit a suite of candidate 1-, 2-, and 3-stage time-to-event models (n = 16 total models) that investigated 'size' (length), 'release age' (0 or 1), and 'condition factor' (K) covariate effects on survival. Models were implemented in a Bayesian framework using JAGS with the R package 'rjags'. Full model specifications, example code, and Keuka Lake Cisco time-to-event data (provided by NYSDEC) applied to this analysis are available here:
