| Abstract |
St. Anns Bank, situated offshore of Cape Breton, Nova Scotia/Unama’ki, was designated as a
Marine Protected Area (MPA) under the Oceans Act in 2017 to conserve and protect benthic,
demersal, and pelagic habitats, in addition to the high biodiversity and productivity in the area.
Since 2015, the annual Snow Crab Survey (SCS) has been supplemented with enhanced
stations inside and adjacent to the MPA, which, in addition to Snow Crab, provide length and
weight data on fish and invertebrate bycatch, as well as diet data collected from fish stomachs.
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. |
