For anyone curious about this who didn't want to watch the video, the trap consists of:
1. A large woven cone
2. A smaller woven cone without a tip
The smaller cone is placed in the larger one; shrimp swim into the small cone to explore, but then get caught in the space between the two cones when they try to get out (presumably because it's difficult to find the single entrance).
He mentions that the only skill necessary is basketweaving -- I wonder if it would be possible to carve something similar (two interlocking geometric shapes) or if the trap being woven is essential to its function, for example, for allowing flowing water in to entice shrimp.
One of the parts that stood out for me was
> In practice, a long stretch of creek might have several traps collecting food each day without any effort on the part of the fisherman.
If he were to go whole hog long-term, shrimp traps would free up his time for doing other crafts in ways that spear fishing or actively hunting wouldn't, though I suppose the local yield of shrimp would factor into that (whether he could collect enough calories consistently to fund his other efforts).
