Are you thinking of a different movie? Perhaps you're thinking of:
* "The Killer Fish" (1966): This was a short film about a man who gets attacked by a fish.
* "Piranha" (1978): This was a popular horror film about a group of piranhas that are accidentally released into a lake.
* "Jaws" (1975): This is the classic movie about a great white shark that terrorizes a beach town.
If you could provide more details about the film, I can help you pinpoint the correct title and provide information about its release date.
