Picture a big flat one of these.

It'll work until you start drowning otters and caimen.

I'm thinking, using PVC tubing for a frame with a 4'X4' foot print and about 1'-2' high, mesh or netting all around (top, bottom, sides). On one side, at the bottom have a 4''-6'' hinged door that can only open inward & once the ray is in and the door closes it can't be pushed to open outward.
The door would have to be made with a material that is not too flexible but not too heavy so the rays can push it open to enter. Rays are quite strong and determind so I think they'd have no trouble pushing it open but other fish besides catfish would have trouble swimming against the door to open it.
You could place bait at the opposite end and susspended by a string from the top and hanging down midway to attract others in because the 1st ray in will eat all the bait.
Basic idea drawing for this concept.

This is similar to what I came up with, except I had the spring trapdoor hinged at the bottom instead of the top,probably made of plexi, and the bait in a small anchored container so they can sense it but not get it. I also think only the front ( door) panel would need to be constructed, the rest could be improvised with a wire frame and netting or some kind of local basket weave and all held together with wire or fishing line. It wouldn't have to last forever, just a few weeks.
The door itself could be constructed to allow only smaller rays in , or larger ones too, by adjusting its size
So I guess the intricacies and details of the front door design are next.

Something out of coated metal mesh would work well. Keeping it as flat as possible will be the other trick to this as a lot of the competition fish are going to be more verticle than flat like the rays. The spring door being flush to the river bed is also a good idea.
This was my idea, sorry for the drawing in paint. Let me know about any questions or anything, or cant read it.
Also, I forgot to enter a small tube through the black part that would bring the scent about the half circle more easily
