title: Integrating acoustic telemetry and demographic modeling to inform cisco (Coregonus artedi) restoration in Keuka Lake, New York

description: Stocking is an important conservation tool to restore fish populations.
 Yet, assessing restoration success is often limited by a lack of
 field-based demographic information at low abundance, particularly for
 juvenile fish. Using outcomes from a cisco (Coregonus artedi)
 reintroduction to Keuka Lake, New York, USA, we demonstrate a data-driven
 approach to assess fish stocking performance and evaluate the likelihood
 of achieving conservation goals. This project includes data and code for a
 multistage time-to-event survival model and population viability analysis
 with a Leslie matrix life-stage model to evaluate re-establishing a cisco
 population in Keuka Lake.

 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](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](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: Sethi, S.A., et al. 2024.
