2018:  13 August, SSRAA Coho Returns

Because of the lag between harvest and coded wire tag processing and tag expansions, it is still too early to assess the current coho season…except that the return of SSRAA’s stock of fall coho is stronger than last year.  Considering 2017 may have been our all-time worst coho survival, this does not mean the run is exceptionally large; at the least, it is much closer to normal.  Things are going in the right direction.  In another couple of weeks we will know how far they have gone in that direction.

Klawock coho are showing in harvest when and where you would expect them.  The numbers may be a little down from last year; but, as with the SSRAA falls, it is too early to draw a meaningful conclusion.  These fish are found in the southern outside troll quadrant in decent numbers.  They are also harvested in D103 and D104 seine.

We will miss a week’s data/harvest because of the coho closure; if all is well harvest should build quickly after the 15th.

2018:  6 August, SSRAA Coho Returns

Stocks:  SSRAA releases a number of different coho groups including: summer (Snow Pass) coho at both Neck Lake (Whale Pass) and Whitman Lake Hatchery; Klawock River Coho at Klawock Lake and the Klawock River estuary; Crystal Creek Coho from Crystal Lake Hatchery; and, SSRAA fall (Chickamin Stock) coho from Nakat, Anita, Whitman Lake Hatchery, and Neets Bay.  The releases vary in size from the largest at Klawock and Neets Bay to relatively small broodstock releases at Whitman Lake. These coho stocks are different .

It is still too early in the season for the attached graphics to have much meaning, the numbers are growing quickly.  It looks as if the return is better than what we experienced in 2017…which was dismal.  Things have gone in the right direction.  Klawock coho are starting to show in harvest when and where you would expect them; likewise for the larger releases of SSRAA fall coho.

The coho closure will happen shortly, and if all is well harvest should build quickly after the closure.

As is always the case with coho coded wire tag recovery/processing; generally the most recent week is dramatically underrepresented in the data.

We will update this information weekly as the information is available.

16 July 2018:  Snow Pass (summer) Coho Update:

After the poor return of these fish last summer we were only guardedly optimistic about the 2018 run; and, it has started slowly (6,700 coho harvested through stat 28).  The coho/boat harvest in D106 (70 fish/boat) is only about half of what it was at this date last year.  In addition, effort in D106 is also only about half of what it was last year.  D106 is a large area where the drift fishery can target sockeye, chums returning to Burnett Inlet and Neets Bay, and/or “Snow Pass” coho returning to Whale Pass.  And, effort is likely down because opportunity (time D106 is open) is down. Individual boats fish differently related to which of these returns they are targeting.  With so little participation, coho catch/boat, is not as meaningful without knowing how many boats are targeting these fish.  Whatever the case, the return generally lasts until mid-August and related to a recent extended period of high pressure, the return is probably later than usual.

We just completed our first cost recovery harvest from the raceway on Neck Creek – about 2,100 fish were removed.

Anecdotal information:  sport fishing in Whale Pass is good with a lot of participants.
