That's a good idea.
I was fortunate enough to spend some time playing, "fisher gatherer" out of Juneau in early July, we had our pots rigged similar to "slabhunters" image.
I found it interesting that the State of Alaska requires all sport Dungie gear to be rigged as follows.
Copied and pasted from Alaska regulations.
(1) A sidewall, which may include the tunnel, of all shellfish pots must contain an opening equal to or exceeding 18 inches in length, except in shrimp pots the opening must be a minimum of 6 inches in length. The opening must be laced, sewn, or secured together by a single length of untreated, 100% cotton twine, no larger than 30-thread (see illustration). The cotton twine may be knotted at each end only. The opening must be within 6 inches of the bottom of the pot and must be parallel with it. The cotton twine may not be tied or looped around the web bars. Dungeness crab pots may have the pot lid tie-down straps secured to the pot at one end by a single loop of untreated, 100% cotton twine no larger than 60-thread, as a substitute for the above requirements; the pot lid must be secured so that, when the twine degrades, the lid will no longer be securely closed.
