a couple of lake wide

Does this take into account the number of fishermen? Is that a valid factor to consider? 

I don't quite get the harvest graph.  Looks to me that the harvest of kings is very high and quite stable while all the other species have ups and downs - often double the number of cohos harvested. It also looks as though brown trout are the most harvested species.  What am I missing? (Besides someplaces in the lake catching a whopping number of kings and browns.) 

It's a stacked graph, every band is additive to 100%.  So that tiny sliver of  pinkish/salmon color at the top is brown trout (the least harvested species at about 5% or less of the total)

Look at the far right year to understand how it works. The purply steelhead on the bottom is about 10-12% of the harvest, and the blue lake trout is another 10-12%, and combined they make up 25% of the harvest. 

Then the green coho band goes from about 25% to just under 50%, so the coho was 25% of the harvest.  Then that ugly brown color is chinook, and it represents about 50% of the harvest. Then the tiny slice of browns at the top. 



Regarding Fusky's question , the reason it is in percent is to control for the number of anglers and keep everything apples-to-apples over time. Since obviously total harvest is in part dependent on the amount of fishing, in addition to the amount of fish and other factors.  This particular graph is interested in the composition of the harvest, not the total amount of harvest.
