A still image taken from BRUV video (depth 160 m) to illustrate the potential for stripey trumpeter to be a key indicator species within the Flinders Marine Park, and the extent that canyon-head incisions in the shelf in this AMP are productivity hotspots that are actively targeted by stripey trumpeter. Presumably the bait fish species attracted to the hotspot are a significant source of food for the piscivorous trumpeter, and the exposed deep-water reef system at the canyon head appears to provide optimal habitat for the trumpeter. Upwelling (or downwelling) currents at the canyon head presumably keep the deep reef systems from being buried in sediments.
