5/15/2013 9:08:00 AMHave you ever noticed that virtually all the fish you catch are sexually maturing adults. This means with the exception of some late season juveniles the fish not caught last year would have spawned and died last fall and would not be available this year. Thus the fish supporting a given year's fishery are those that were able to survive from small fry to the last year of their life.. If excessive harvest via the 10 fish limit is occurring to the degree to effect the fishing this early in the season that harvest would have to occur before this time of year
How has been the fishing been this winter and early spring?
Are lots of fish being before this time of year?
I spend a fair amount of time fishing Stevens and talk with lots of anglers. Given the catch rates that are the "Norm" between the first of the year and early May the daily limit would have to reduced to less than 2 fish/day to significantly reduce the harvest before this time of the year (how many are actually catching even 5 fish during the early season..
Is that what folks are suggesting or what they want to see?

5/15/2013 11:22:00 AMThat, the derbies, and multiple guides, plus the crappy water condition in the creeks and lakes, its kinda surprising there is still a population of fish. Im sure the biggest problem is pressure though. I wont point fingers at anyone but there are a couple people that started catching and taking at least 2 or 3 limits of fish a day (twice a day) all summer long, for a couple summers.
Just like every other body of water, the guides sniffed up a little money, took way too many fish and brought too much attention to the lake.

5/15/2013 12:01:00 PMIf proof is provided that bass are a significant contributing factor (there's typically more than one culprit) kokanee fishers may need to start engaging in population control. If some SMB end up on my line I may have to take a peak at their stomach contents, my grandfather and I kept and ate bass all the time growing up. They may appear on the menu again....
Anyhow, those look like nice kokanee Steelheadin360! Good work!
f_n_f - report them to authorities if you can! That's not right or justifiable anyway ones looks at it.

5/15/2013 2:41:00 PMThe smallmouth have been in Stevens for approximately 3 decades. So it is hard to believe that they suddenly have become a problem. Generally speaking the smallmouth and the kokanee use to very different parts of the lake with the kokanee suspended over the deep water so in theory at least there should be little interaction between the two. Now the interactions between the smallmouth and say the cutthroat is a different story.
Artic Fox -
I too noticed the much heavier infestation of those parasitic copepods in the kokanee the last two years (maybe even worst this year). In the 5 or 6 years for last year rarely saw any of those critters on the kokanee - the coho and sometimes rainbows would have heavy infestations. Generally speaking those parasites cause only minor problems for fish like kokanee but a clear indication that something different is going on in the lake's ecology. Could be something as subtle as changes in the timing of the phytoplankton and zooplankton" blooms".

5/16/2013 6:28:00 AMThankfully there are no mykiss shrimp in Stevens.
The spawning areas for kokanee in Stevens is very limited. There are no know beach areas in the lake (need upwelling springs and gravel) for the fish to use. There is limited areas in Mitchell/kokanee creek where most of the fish spawn. A few spawn in Lundeen Creek and while some us the outlet the fry that hatch there are unable to swim back upstream so those don't contribute to the lake population. Those spawning in the two inlet streams do contribute to the lake population though those numbers vary quite a bit (depending on stream flows while the eggs are in the gravel/flooding). It may be that the variability in contribution is accounting for the differences we see in adult abundances.
In terms of the fishing in any given year the catch of the hatchery fish (which come form :ake Whatcom) is not effected by the total angler harvest (bag limits no difference). While the harvest can limit the numbers of fish escaping to spawn in the tributaries. However before jumping to any conclusions we should consider the limited spawning habitat available and the significant differences in the fecundity (# of eggs/female) of kokanee. An 11 inch female will have something like 300 eggs while a 15/16 inch fish will have more than 1,500 eggs. In other words have a 1/3 as many large spawners as small spawners may actually result in more eggs being put in the gravel.
In other words it is hard to make the case that the 10 fish bag limit is limiting future fishing of either hatchery or wild kokanee. There are so social aspects of Lake Stevens kokanee management that could argue for a lower limit - it would make it easier for more anglers to catch the "limit". Lower the limit would potentially reduce the catch of the more successful anglers and result in a few more fish being available to the less skilled/experienced anglers. But I stress such arguments are not conservation/biologically based but social.
