Berg’s assistant Eric Black, first team coach Iain Brunskill and goalkeeping coach Bobby Mimms are also seeking pastures new.
A statement from the Championship club, who axed Steve Kean earlier this season, said: “This decision has been taken following a very disappointing sequence of results.
“The club thanks the four men for their efforts and wishes them every success for the future.”
Berg, who signed a three-year contract on October 31, oversaw his 10th match of the season on Boxing Day as Rovers slipped to a 1-0 defeat at Middlesbrough.
