PORTLAND — There are some new restrictions for trap fishermen as their Gulf of Maine shrimp season gets under way.

Maine Marine Resources Commissioner Patrick Keliher lowered the daily limit from 800 pounds to 500 pounds for trappers for their season beginning Tuesday. Trappers will be allowed to haul around the clock, Monday through Saturday.

Late last week, Keliher also lifted time-of-day restrictions on trawlers, allowing them to cast nets around-the-clock on Mondays and Wednesdays, the days they’re allowed to fish.

The shrimp season got under way on Jan. 23 with a big quota reduction that lowered the limit to 1.4 million pounds, a 74 percent decrease from 5.3 million pounds last year.
