Analysis of the enhanced snow crab survey for monitoring conservation priorities in St. Anns Bank Marine Protected Area / Nicholas W. Jeffery, Rémi Daigle, Brent J. Cameron, Amy Glass, Jaimie Harbin, Harri... : Fs97-6/3650E-PDF

"Here we investigated trends in biomass, species richness, and animal size data inside and outside the MPA between 2015-2023, as well as community composition and predator diets. Species richness from the SCS continues to increase as additional stations are sampled. Power analyses of the trawl data to investigate catch per unit effort in several key species revealed that additional stations would be required to adequately monitor changes in animal abundance and richness in the MPA at high power (>80%). Overall, the SCS provides vital information for monitoring the MPA’s conservation objectives related to biodiversity and productivity, but additional years and stations or new supplementary data streams will be needed to confidently identify trends over time"--Abstract, page ix.
