Bengal were 11 overs in arrears, including seven in the first innings, something that has happened for the second time this season after the match against Saurashtra.
Shukla's teammates were fined 50 percent of their match-fees for the same offence.
"As it has happened for the second time, it's termed as 'serious offence' and hence the captain is docked the full match fee," Match Referee Rajendra Jadeja told reporters.
In fact, Shukla has to ensure that the team bowls within the permissible limit in their semifinal against Maharashtra to avoid a ban in case Bengal make the final.
"Anything less than five overs is considered a minor offence and above that tantamount to fine. A repeat of a slow over rate for the third time may lead to a one-match ban."
Bengal face Maharshtra in the Ranji last four in Indore from January 18-22.
