Surveys of long spined sea urchin (Centrostephanus rodgersii) and barrens habitat, Kent Group, Tasmania 2000

Quantitative surveys were undertaken at four sites in the Kent Group, north eastern Tasmania (southern and northern shores of East Cove at Deal Island, Winter Cove at Deal Island, NE coast of Dover Island) by divers using underwater visual census methods to survey the reef habitat.

Purpose
To determine the distribution of the long spined sea urchin (Centrostephanus rodgersii) and associated barrens habitat on the east coast of Tasmania; to compare the standing stock of black lip abalone (Haliotis rubra) and southern rock lobster (Jasus edwardsii) in barrens habitat with that in adjacent seaweed beds.

Resource lineage

Statement
At each site, four belt transects were laid 50-150 m apart perpendicular to the shore over 3 - 18 m depth. Depth, percentage cover of different substratum types (including Centrostephanus rodgersii barrens) and algal species or guilds, and counts of all sea urchins (Centrostephanus rodgersii, Heliocidaris erythrogramma), rock lobsters (Jasus edwardsii) and abalone (Haliotis rubra and Haliotis laevigata) were recorded in consecutive 5 m sections of each transect. Each transect was 2 m wide (1 m to each side of the laid line) and varied in length depending on the extent of reef to a maximum possible of 100 m. Note that transects ceased whenever the tape reached the reef edge (0-100m). Additional spot dives at two other sites in the Kent Group (Little Squally Cove and the northern side of West Cove) were used to record the extent of Centrostephanus rodgersii barrens. Similar observations were made on a drift dive in Murray Pass. These results can be found in the report (uploaded).
