Do Fish Pee?

[burgerchow]

OK, I've caught tons of fish, and when gutting them, never have seen a pee bladder. Where does the pee come out? Same place as the poop I guess?

osmoregulation (fluids/salts/dissolved gases) primarily exchanged at gills and secondarily through GI system

You'd never see the urinary bladder cleaning a fish, but they do have one. In the vent of the fish there are two openings; one for the "poop" that is connected to the digestive tract (anus), and the second (urogenital aperture),where the "pee" comes out, is connected to the urinary and reproductive systems.
