Is this different than the smelt we catch in places such as deception pass?
1. Environmental factors man has caused 2. Commercial overharvest - in that order..Smelt are one of the main food sources for sturgeon too especially on the Columbia (NOT GOOD!)

and pulp mill discharge, light pollution, rising ocean temperatures due to climate change.....Still somewhat on topic. I'm not trying to determine the impacts as much as trying to make sure my timeline is somewhat on.So maybe a few of you can correct me where I'm wrong on this....but back when logging was first practiced here in the northwest (late 1800's/early 1900's), it was much less environmentally conscious----built roads, crossed streams, cut every tree standing. They pretty much kept similar logging practices until what the 1960's? 1970's? And huge runs of nearly every kind of fish were still reported year after year. These declines in fish stocks they keep talking about all seem to focus on mid-1990's on. So....the fish were still doing great during, what 90 years of 'horrible' logging practices; but in the years (more than 5 cycles of runs worth) with 'better', eco-friendly logging methods the fish are now not hacking it? Is my timeline off? Were the runs dropping noticeably back in the 30's? Or the 70's?
