Grandpa my apologies.... my intent was to point out that the use of the word "extinction" in the case of geoducks was misleading. Approximately 75% of the resource will go untouched by harvest as pointed out by my post. Like I said there's a ton of info available....please check it out.

Geoduck depending upon location it takes about 5 to 6 years to grow one of you to a 1 kilogram or 2.2 pound whole live weight.....just exactly what the market wants.

BTW the commercial shellfish industry is currently culturing geoducks in the intertidal and within the next couple years will be producing 2 million pounds annually themselves. The technology already exists to rebuilde harvested wild stocks if needed or produce them as a crop nearly seperate from wild stocks. Knowing that some may raise the issue I would like to point out that recent studies on geoduck genetics has not been able to identify genetically seperate stocks. I could explain why but just don't feel like spending hours on the internet teaching a class on geoduck reproduction and life history.
