NAUBINWAY, Mich. — Two Upper Peninsula brothers accused of dumping fish remains for years into a Lake Michigan bay have been sentenced to six months of home confinement.

Carl and Donald Frazier process whitefish in Naubinway in Mackinac County. The government says they dumped barrels of fish guts into the water and shoreline of Epoufette Bay.

The Fraziers pleaded guilty last summer to negligent discharge of pollutants, a misdemeanor. Their company pleaded guilty to a felony.

A federal judge last week sentenced them to two years of probation, including six months of home confinement. Fines add up to $80,000, well below the maximum.

The government conservatively estimates that at least 216,000 pounds of fish remains were dumped.
