Funny for you

Parks Board warden finds an Indian man at the Blue Lagoon with ten shadfish in a bucket."That's way over the limit," he says. "You're under arrest."
"But lahnee, please," the man says, "these are my pet fish from home. Ijust bring them down here to let them swim free once a week. When I whistle, they all come back and get into the bucket to go home."
"I don't believe it." says the warden.
"OK... I will show you." The man promptly dumps the shad into the sea and gazes after them as They swim away.
After a minute, the warden says, "OK, so how long?"
"How long what?" says the man.
"How long till you call the fish back?"
"What fish?"
