From the months of September through June, inclusive, commercial fishermen must fish in water depths of at least 5 fathoms (30 feet) or deeper to minimize incidental catch of salmon and trout.

c) During the months of August and September, all gill nets set in the Illinois portion of Lake Michigan in waters up to 20 fathoms (120 feet) in depth shall not be set prior to sunrise and must be removed from the water prior to sunset on the same day.
d) During the month of July, all gill nets must be placed in waters greater than 20 fathoms (120 feet) in depth to minimize the incidental catch of yellow perch.
