Friday's Innovation Inspiration - Fish mating calls?

I'm going to handle this Friday's Innovation Inspiration a bit differently from the way I usually do; rather than helping you find information so that you can try this on your own, I'd like to know what you would use to display fish mating calls. Obviously you would need a few fish who're willing to let you in on their sweet talking. Tell me and the other users in the comment section below.
