Interesting indeed. All the old timers my pop fished with referred to sandlance as candlefish back in the day. I guess we know better now that they are two different species. I know the Columbia river smelt populations have been down for awhile now, but seem to have rebounded a bit this year. I can remember filling up a 5 gallon bucket with two scoops of the net back in the day on the Cowlitz. Floured, seasoned and fried up in butter, those those smelt were delicious.
