Biologists began studying sockeye salmon on Kodiak Refuge's Akalura River in 2015, gaining valuable information on salmon enumeration for a remote river system last monitored in 2002. The study uses still photographs and video in a two-stage sample study to establish an estimator and calculate the total run size as well as basic run characteristics. Results from this project also allow biologists to gain more experience with the methodology and development of an estimator, and potentially expand monitoring to other small salmon systems.
