A fish wholesaler and his son pleaded guilty in the largest investigation of illegal commercial fishing in the Chesapeake Bay and Potomac River. The Justice Department said Robert Moore Sr. and his son Robert Moore Jr. entered their pleas yesterday in U.S. District Court in Washington. The elder Moore owns Cannon Seafood Inc. in Georgetown, where his son also works. Prosecutors said the Moores and at least three fishermen illegally harvested and sold hundreds of thousands of pounds of striped bass, which are highly protected. Under terms of a plea agreement, Cannon Seafood has agreed to pay a fine of $80,000 and pay $28,000 in restitution to the National Fish and Wildlife Foundation. Moore Sr. has agreed to pay a $40,000 fine and pay $15,000 in restitution to the NFWF, and Moore Jr. has agreed to pay a $30,000 fine and pay $10,000 in restitution to the same foundation. The court set a sentencing date of May 8.
