Lobstermen are worried that last summer’s low prices could return this year. The Portsmouth Herald said lobstermen have been telling Maine Marine Resources Commissioner Patrick Keliher at recent meetings that something needs to be done should prices dive again. They are not sure what the answer is, but they oppose limiting lobstering to three days a week. More than 50 lobstermen filled the meeting room of York Public Library on Thursday. Some expressed frustration over the price difference last summer between what they were receiving for lobster and what restaurants were charging. Keliher said Maine lobstermen last year caught 123 million pounds of lobster, up 18 million from the year before, but worth $3.7 million less.
