KX Perspectives from Kitasu Bay

Bread basket for Klemtu
Major settlement area for Kitasoo people
Major FSC harvest for KX – produces over 95% for food/trade.

Most reliable spawn area on coast. Fished for millenia

A “spring” or “source population” for herring
Fished heavily for RH from mid 70 s to 1990. Avg. 1500 ton/year .

Significant conflict and confrontation with FSC fishery.

Used continuously by KX since early 1980’s for commercial SOK
Defended through legal/direct action since early 1990’s (post

Sparrow)

In 1990’s KX more active in mgt. diverted herring fisheries to
ther areas to preserve Kitasu Bay.
Began recording FSC catch in 1993
From 1993 - 2003 – the 3 significant RH fisheries resulted in

major reductions in FSC catch.

Kitasu Bay is a major staging and spawning area (over 10,000 ton
n a regular basis)

KX perspectives on Aristazabal Herring Stocks

Aristazabal stock differs from Kitasu Bay stock in

space and time (often earlier).

Difficult area to fish due to weather and rugged

poorly charted coastline.

Generally a smaller stock than Kitasu Bay (1000-

3000 t).

2013 – 950 tons observed spawning
2014 – Fished by GN – 700 ton (100 ton spawned)
2015 – Very few fish observed (small spawn)

SLIDE 12

KX perspectives on East Higgins Herring Stocks

East Higgins stock differs from Kitasu Bay stock in space

but usually similar timing.

Unsure if it is related to Kitasu or Reid Pass stock.
Generally a smaller stock than Kitasu Bay but is typically

reliable.

KX uses most years for commercial SOK.
Fished heavily by RH prior to 2008. KX diversion.
Stock crashed with almost no spawners from (2008 -

2014) – serial depletion?

2015 – Spawn finally returned – 9.5 km but some

mortality observed.

Summary KX Herring Observations

1. Major Roe Herring Fisheries and FSC Fisheries cannot easily exist in the same space without impact to the FSC harvest. 2. Areas must be set aside as Sanctuaries for FSC harvest. 3. Closed SOK fisheries co-exist well and appear to enhance FSC harvest. 4. Herring in the KX Territory are made up of multiple stocks that differ in time and space. 5. Staging populations/areas often differ from spawning populations/areas. 6. Intermingling of stocks is likely but there are anchor (source) populations. “Herring spring” 7. Persistent gillnet selective harvesting reduces size at age of herring. 8. Serial depletion of herring stocks is a concern. 9. Managing areas 6 – 8 (central coast major stock area) as a single stock may be leading to serial depletion.
