It's about time: A multistate semicontinuous time mark–recapture model to evaluate seasonal survival and movement rates of juvenile Coho Salmon in a small coastal watershed
Nicholas P. Van Vleet, Darren Ward, Nicholas A. Som, Daniel C. Barton, Colin Anderson, Mark J. Henderson
2024, Transactions of the American Fisheries Society (153) 541-558
ObjectiveMany mark–recapture models assume that releases and recaptures are discrete events, and researchers often aggregate continuous recapture data (e.g., passive integrated transponder [PIT] detections) into coarse temporal scales to satisfy this assumption. This temporal discretization could result in parameter biases by ignoring the individual heterogeneity in the...
