Queen Charlotte Islands Herring – ShoreZone Analysis
Queen Charlotte Islands Herring Spawn Dataset • 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)
Moresby Island Englefield Bay Herring spawn polygon data were snapped to Shore Units
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).
Expanded view of Juan Perez Sound shows frequency of occurrence relative to Shore Units – 11 km of High Frequency Spawn Occurrence are shown.
Comparison of Island-wide Occurrence to High-Spawn Occurrence Occurrence of BioBands (island-wide) Where relative proportion of spawn locations are greater than island-wide occurrence, a spawning preference is indicated: Fucus Ulva Soft Brown algae Zostera Macrocystis
