Contrary to popular belief and myth, submarines (other than the one at Disneyland) do not have windows or any other means of looking at fish or other creatures in the ocean. Submarines are sophisticated weapons, and fish aren't they're primary mission.
Submarine Sonar Techs (myself included) do hear fish when boats come to periscope depth and biologics (the technical term for sea life) surround the boat. While a periscope can catch occasional glimpses of fish, that's not its primary function.
The notion comes from the old '60's movie and TV show "Voyage to the Bottom of the Sea", featuring the fictional submarines Seaview. It had transparent hull plates on the very front of the boat. However in reality, submarines don't spend that much time at depths where fish are visible, and even then they don't tend to get close enough to see.
Techically, that would be the U.S. Navy's first submarine, USS S-1 (SS-105) , built by John Phillip Holland. Though the first submarine that was used in combat, David Bushnell's Turtle (Revolutionary War), the U.S. wasn't in fact a country at that time.The Confederate submarine H.L. Hunley was also not technically an American submarine, effectively being used by the Confederate Army (manned by Confederate sailors), but it was never a commissioned vessel in any navy.
