I have told the story before on here about the Fisheries catching a guy who had a lot of guys catching the huge breeders and bringing him the eggs that he packaged them in his Vancouver, WA motel and sending back east to Chicago to a company that finished making caviar and selling. They figured (can't remember the exact number although I have the article up in my rod room) he and his group killed 25% of the breeders on the Columbia river system. This is so sad because of the very long time it takes a Sturgeon to reach a maturity to lay eggs which I have read approximately a 6' fish and 25 years. Way longer than the 3 to 5 years for a salmon to spawn. When Salmon fishing in WA fell on its lips many years ago many fishermen started fishing for Sturgeon, me included and were in my view over fished and now limits have been drastically reduced.
