| Comments | The crab had been long dead and little more than a shell remained. It was entangled in the net. I only found it while removing as much marine plant life as I could before estimating weights. |
Additional Information
This area is so full of net and cloth fragments, almost all entangled around and all along a long pipe that comes from underground just off shore and runs out to about 3-4 meter depth. The pipe runs along the bottom but has several 1 meter vertical sections that hang up alot of nets.
mesh bag. Ironically a mesh bag with operational zipper. Using trash to clean trash! However on this dive I didn't use it.

Comments and Feedback
I spent great effort to work with a knife and cut free these sections. 2 of them were from the same much longer piece that was wrapped around a pipe. The 3rd darker colored section was a piece of a much larger chuck of mostly tangled ropes and cloth I spent 30 minutes alone working on. The "base" if I might call it that was embedded/tangled in a dark corner of two rocks and I was a bit too scared to stick my hand in there to try to free it. Next week I'll try again with some type of long hard tool. Also note that I did my best with this report, but the pictures show so many tiny things all mixed in there. To completely free everything and give a 100% accurate report would have meant basically cutting the nets into tiny pieces and risk those small pieces finding their way back to the ocean. I chose to make the report " conservative" on the numbers in light of that, but zoomed in examination of the pics will reveal so much more pieces and types than reported.
Need a better knife/scissors for next site. I initially began trying to free what could only be called a "massive" mass of rope and cloth, but the ropes holding it together were heavy and simply too much for my knife. Next time also need to take a second tank, as constant cutting/pulling caused me to use air quickly. I often switched between snorkel and air using air for mostly on the bottom where I was holding myself under my the mass to cut free.
