I commercial dove for 20yrs and harvesting octi was a great way to make a few extra bucks,about a dollar a pound in the 80's, my first expereince with these critters is one i won't soon forget ,the other guys i was with at the time were all versed onthis and of course being the new guy i was to proud at the time to ask for advice ,all i new is they were worth money ,the first one i see is about 30lbs out in the open ,i,am harvesting cucumbers ,i've got a mesh bag to put them in ,so i crab this octi and start making my way to the surface ,one problem he's got a couple of legs on a rock holding me down then he begins to intertwine his legs through the cuc bag and around my arms pinning them to my chest and then up to the mask and then pulling on my reg,iam shitting myself i can't grab my knife or try and pull the legs off,so i hit the inflator valve and hope the presue will pull him off,sure as **** it works i'am sure i had somebody looking over my shoulder that day,i dump air out as i hit the surface the dive boat comes alongside there laughing there bags off ,the human prezzel it was very very soon after i learned the proper technique ,you stab them between the eyes ,not even a week later iam off saltspring island diving for swimming scallops and i come across this huge den 2 ft of shells piled up and 3 large box crab shells as well, i go back up and let the other divers know and the most expereinced guy says he will give me hand with him,get back to the spot and i bleach him out and this thing keeps coming and coming its fricken massive12ft plus arms,ive seen and caught 100 lbers and this one was still the biggest ive ever seen,this thing finally comes out and hes pissed bright red and ready to roll i look back for buddy and hes bailed on me mr expereinced ,so its me and him and considering my last try he was left in peace,in hit the surface buddy says that was the biggest octi he's ever seen and there was know way in hell he was tangling with that,i killed thousands of them to support the commercial fishery in the day and now its come full circle as a guide arguing over the right to fish.
