Fishing in Lake Michigan for anything that swims by. Steelhead, menominee, perch, salmon. If you're lucky you may catch something. Sheephead, goby. If you catch a goby, don't throw it back. These prolific little fish do not belong in the Great Lakes ecosystem. They arrived by mistake and threaten to overtake niches that should belong to other fish. People who catch gobys dispose of them.
You never know whether anything will bite. That's fishing.
