Purple Urchin Removal Events on the North Coast

Someone please help me with the math:

The purple urchin take limit was changed from 35 to 40 gallons per diver in April 2018. According to Cynthia Catton, a State Fish and Wildlife environmental scientist, “Each diver can fill four five-gallon buckets.”

40 gallons = 4 x 5 gallon buckets????

Correct.
The limit was increased from 35 urchin to 4 five gallon buckets

4 x 5 gallons= 20 gallons.

Hmm...

It's an error in the article.  The limit was changed from 35 individual urchin to 20 gallons.  She probably got confused because we were pouring the crushed urchin into 40 gallon barrels to haul out.

The new common core method......just go with it! lol

Thanks again for everything you and Matt did to organize. Pretty amazing to see the small army of people who showed up, although there are a hell of a lot of coves and urchins to go.
I saw on FB that you are already organizing the first Mendo one at Albion. I had a question on that. Now that I have some experience both smashing and collecting, I am convinced any diver can destroy with a hammer a multiple of the number of urchins he or she can collect, bring to surface, and move to shore, much less dispose of there. And of course it was impressive that up at Ocean Cove you had organized a jet ski and that other small skiff, but most of us can't count on that. I know you said DFG was afraid smashing would trigger spawning. My question is, when DFG (or other) figures out the science of spawning, can we have events that are outside that spawning window (I assume it's a calendar thing, hours of daylight or water temp triggered). For instance, if it's safe to smash them in Sept, then why not do a big event then? Or April or whenever works? Also I heard several times people mentioning that it seems somehow more appropriate to be crushing them in the ocean where they immediately become part of the (deprived) local food chain. Not complaining at all, just hoping we can increasingly leverage the available manpower!
Thanks!

My Son and I had so much fun diving Ocean Cove for the last urchin event,
 I just made my reservation for Albion in July for the next one.
For the next dive I am bringing my Wife and our kayaks to help out too

Crushing is the preferred method all over the world. The fear in the department that crushing would cause a massive spawning event is not shared by any other biologists that I know of.  I have to do what I can with what I'm given. Cynthia Catton has said that she will never approve a recreational smashing event and I believe that is the opinion of the department and the commission.  That said, I have submitted a scientific collection permit application that would allow us to smash if the department goes in the week before to sample and rate the probability of spawning due to crushing.
