What are some things that have been tried to stop the impact of zebra mussels, and why or why not have they worked?
In enclosed situations like in a power plant, zebra mussels are more easily controlled by chemicals such as chlorine and using filters. But in open environments like lakes and rivers, there is little we can do to control them. We cannot treat with chemicals in those situations. That is why it is so important not to spread zebra mussels by boats or any others means. Once there, they are impossible to eliminate. Unfortunately we are going to have to live with them.
