All the pots I've seen have the same ports to let them in, about 2"x2". None have entrapment doors like crab pots. I think they'd be too heavy for shrimp to push through. Although easier to get in (with the ramped entrance access) than out, I think the water pressure when retrieving is what keeps them in.
Thanks for the reply!
