Many harbours around P.E.I. were still ice-bound around the first of May, and some harbours started more than a week late.
The P.E.I. Fishermen's Association asked for an extension of the season to make up for the late start, and on Thursday Fisheries and Oceans Minister Gail Shea announced a four-day extension.
"This four-day extension strikes the right balance between ensuring we protect our precious resource while allowing our fishermen to get more days out fishing," said Shea in a news release.
The season was due to end July 1. Fishermen have been waiting anxiously for the decision, because they need to prepare for the extension.
There are concerns about extending the season, because lobster begin to moult in July, and newly-moulted lobster generally do not survive to get to market.
