Tiny ocean plankton holds clues to the future of Maine lobster

UMAINE NEWS• August 21, 2026

The future of Maine’s lobster industry may depend on a creature the size of a sesame seed. Researchers at the University of Maine have discovered that planktonic baby lobsters, or larvae, preferentially feed on Calanus finmarchicus, a tiny, calorie-rich zooplankton species, during one of the most vulnerable stages of their lives. Their new study upholds a theory advanced by scientists in the past decade, and one that may be relevant to recent declines in Maine’s lobster harvest. Scientists have also observed declines in both the availability of this key food source and the number of young lobsters surviving into adulthood in the Gulf of Maine.
