Authorities said the cull was necessary after six people were killed in shark attacks.
No great white sharks, to whom most of the attacks were attributed, were caught.
Australia`s state government said the cull was successfully restoring confidence among beachgoers.
It is seeking to continue the programme for three more years.
"I think the strategy`s gone very well, bearing in mind that it`s a very broad strategy, and that`s basically to protect those people that swim in those popular areas," Western Australia Fisheries Minister Ken Baston said.
"While of course we will never know if any of the sharks caught would have harmed a person, this government will always place greatest value on human life."
Protesters argue that a shark cull is not the answer and would only damage the sea`s delicate ecosystem.
"The policy is very unpopular, it has hardly caught any of the sharks it was destined to catch," said Labor fisheries spokesman Dave Kelly.
