Unless I'm mistaken, the fish head upstream to die. None of them will encounter the cannon twice, unless the same river has multiple dams on it.

Similar to how the salmon "learned" to swim back to where they were born, the increased survival frequency of salmon who can efficiently negotiate such a cannon would be expected to change the population.
