Assuming its the same as what I had in the 70's (it looks identical) the shrimp swim up over the opaque baffles (attached to the dish bottom)and down under the clear baffles (removable) until they reach the center. The removable upper baffles need to be clear (or at least translucent) so that the shrimp can see the light and move toward it.
Note the Hobby Hatchery does have a place to insert an air tube, and the old ones came with an airstone, but when I used it then egg shells would end up in the middle. So instead I bent a piece of stiff air tubing (heat over a candle) at a right angle and placed it so it would blow ON (not under) the surface. This kept a slight current circulating around the outermost ring, which might (or not) have helped hatching, without getting shells in the middle. Anyway, it looked good and made me feel better.
