Most reviews of salmonid escapement estimation techniques have been based on logistical
considerations or site-specific applications and not on statistical first principles. We reviewed …

We evaluated the estimation of six free parameters in the state-space non-linear logistic
production model, using two approaches: likelihood estimation and Bayesian posterior …

The feasibility of using sonar in Alaska's lower Kvichak River, a region with a 3.8 m tidal flux,
to assess the abundance of adult Sockeye Salmon Oncorhynchus nerka was evaluated as a …

Systematic hourly sampling is a logistically favorable method for hydroacoustic estimation of
fish passage through constricted passageways or finite sections of a river monitored by fixed …

Unless accounted for in the estimation, tag loss will cause mark–recapture methods to
overestimate the true abundance of a closed population and to underestimate the …

The upstream migration of adult sockeye salmon (Oncorhynchus nerka) in the Horsefly River
was monitored by a DIDSON imaging sonar during the dominant stock-cycle year 2005 …

Abstract As Pacific salmon (Oncorhynchus spp.) continue to decline across much of their
range, it is imperative to further develop reliable tools to quantify trends in population …

Using a simulation program and video census data (2004–2018) from the Bois Brule River
fishway, Wisconsin, USA, we compared alternative sampling designs to estimate spawning …

Fifteen years of video census data from a fishway at Winchester Dam on the North Umpqua
River, Oregon, were used to evaluate sampling designs to estimate abundance of spring …
