Fish are selfish. They like to eat when they’re hungry, swim wherever they want and they don’t care whose place they’re taking in the stream.
They’re bullies, really.
Unfortunately, there are other bullies in the world, like some corporations who care more about making a buck off fish hatcheries than making sure our salmon stocks are safe.
A bill that lets any corporation put fish into Alaskan waters without stringent oversight is a very bad idea.
