Queen Charlotte Islands

Herring – ShoreZone Analysis


The shorezone coastal dataset as a research tool

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


The shorezone coastal dataset as a research tool

  • 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
