Nice idea, but I'd look for a bit more standardization between the 2 setups in order to draw any sort of conclusions. Same tank size, filters, substrate, decorations, shrimp species (this would be a big one), Male/female ratio, water parameters, feeding schedule, etc etc. With so much variance between the 2 tanks, you couldn't say with any real certianty that the Planaria were to blame for the lower yellow shrimp population even if it does happen. Unless you directly witness planaria eating some baby shrimp. They are mostly active at night though, so without a nightvision cam you may not even see that if it does happen.
To draw some real concrete conclusions you'd probably need like 10 tanks set up identically with 4 of them having planaria. that way if all 4 of the planaria tanks showed slower population growth than the other 6, and that was the only variable, you can reasonably conclude that the planaria were directly to blame for it.

I plan to do the same thing make a little money then move up to the more exotic, expensive shrimp. I mean I could just buy more RCS off aquabid, but I need to learn a little more about shrimp keeping. I really like the cardinal shrimp but those are $$$
