Why does walmart tell you to hold fish over the theft detector?
 
They work by using radio tags on the items and a reader at the door.

It may have something to do with the radio waves?

I dunno but my local pets at home has these detectors and I don't have to lift mine.
 
most of my fish are from walmart and was told almost every time I purchased fish to hold above theft detector while exiting
 
Lol. The cashiers at my walmart ALWAYS say the same thing when I buy fish... "Buying some fish huh?".... I can never think of anything witty to say to reply tho.... doh! Me and my simple mind :)

Nope, just taking them for a walk.
