5203 |a"Spatially-stratified acoustic surveys based on krill habitat characteristics were conducted by the F.G. Creed in the estuary and Northern Gulf of St. Lawrence from 2008 to 2017 to describe krill distribution and estimate biomass. To provide estimates of biomass after 2017, we aimed to rely on acoustic data recorded by the Teleost since 2012 during the multidisciplinary stratified-random surveys of the northern Gulf of St. Lawrence. This document aimed to evaluate methods to intercalibrate the two surveys to provide a continuous time series of krill biomass in the long term. We extended the F.G. Creed survey-based estimates of biomass up to 2017 and developed model-based methods for the two surveys. For the Teleost, the proportion of each krill species was biased and the predicted biomass was overall lower compared to the F.G. Creed survey. Nevertheless, the two data series provided similar interannual variations of krill biomass from 2012 to 2016 and linear models provided effective tools for the intercalibration of the two surveys"--Abstract, page vii.
