These decreases cannot be explained by landings, disease, or survey variation. Reduced sampling efficiency due to storm driven changes to the seabed is most likely. Small oysters increased 2.3% and spat settlement was high. Bonamia infection was 6.6%, non-fatal infections 1.0%, and summer mortality 5.0%—similar to 2021.
