Methods

We evaluated the importance of herring bait for lobster populations in the Gulf of Maine:

  • We sampled the diet of lobsters in fished vs. closed areas to assess how much herring is consumed by lobsters
  • We tagged lobsters in fished vs. seasonally closed areas to determine if herring bait augments the growth of lobsters

Left: Lobsters were dissected to obtain stomach and tissue samples for diet analysis. Right: Lobstermen used more than 60,000 metric tons (~300 thousand barrels) of herring bait per year.
