Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Blue gill in tank

In Lima, OH, there's a refinery called Premcor (it used to be BP).

In their visitor's lobby, they had a fish tank with blue gill and LMB. While I was waiting for my meeting to happen, I dug a few worms from the dirt outside the lobby and dropped them in the tank; both the blue gill and the LMB were eating them.

The refinery was trying to make a point that the water they were taking and using from the local river was actually cleaner (due to their environmental controls) when they discharged it back into the river.
