18 Dan Leus, Fisheries and Oceans Canada, Urchin Fishery Manager “Personally, I see the future of the [ShoreZone] database as being a bible for the shellfish group here. ” Urchin Barren Distribution Fisheries and Oceans Canada using kelp and urchin barren biobands to represent urchin habitat capability. Model complements fishers’ log-book data and DFO dive site data to establish catch quota. “old data”

20 Queen Charlotte Islands Herring – ShoreZone Analysis Queen Charlotte Islands Herring – ShoreZone Analysis

21 The Queen Charlotte Islands shoreline is 4,660 km in length There are 7,895 mapped ShoreZone units Fisheries & Oceans Canada has mapped spawn locations for 27 years (1970 to 1997) Queen Charlotte Islands Herring Spawn Dataset

22 Herring spawn polygon data were snapped to Shore Units Moresby Island Englefield Bay

23 Summary indicates a total of 753 km have had spawn in at least one year of the 27 year dataset. Map shows a few significant locations where spawn was very frequent (16-21 yr of the 27 year data record).

24 Expanded view of Juan Perez Sound shows frequency of occurrence relative to Shore Units – 11 km of High Frequency Spawn Occurrence are shown.

25 Occurrence of BioBands (island-wide) Comparison of Island-wide Occurrence to High-Spawn Occurrence Where relative proportion of spawn locations are greater than island- wide occurrence, a spawning preference is indicated: Fucus Ulva Soft Brown algae Zostera Macrocystis
