What happens to Innsmouth's gold and fish?

I apologize if this is a known thing (I haven't had access to a lot of Innsmouth stories), but the deal is, the Deep Ones get women, and Innsmouth gets gold and fish, right? The town is in a perpetual state of decay, so they're not spending money on that. I guess they could be eating all the fish, but where's the money going?
