Lobster

Homarus americanus (American); Homarus gammarus (European)

A large marine crustacean — once a poor person's food in colonial New England, now an iconic luxury seafood and the foundation of major Maritime fisheries on both sides of the North Atlantic.

From poor man’s food to luxury

The transformation of lobster from cheap food to luxury is one of the most dramatic in food history:

  • Colonial New England: lobster was so abundant it washed ashore in piles. Used as fertilizer, bait, and prison food. Some Massachusetts servants negotiated contracts limiting lobster meals to twice weekly maximum.
  • 1800s: railroads and canning enabled wider distribution. Lobster’s reputation began to improve.
  • Early 1900s: still primarily for working-class eating in coastal areas.
  • Mid-1900s: tourism, refrigeration, and changing tastes elevated lobster to mid-tier seafood.
  • Late 1900s onward: lobster became iconic luxury food, particularly in New England and Atlantic Canada.

A typical Maine lobster boat can produce 100,000+ pounds of lobster annually, supporting major Maritime fishing economies.

Two distinct species

Two main commercial lobsters represent distinct species:

  • American lobster (Homarus americanus) — North Atlantic from Labrador to North Carolina; larger; more abundant
  • European lobster (Homarus gammarus) — eastern North Atlantic from Norway to Morocco; smaller; less abundant

Several other “lobster” species exist (rock lobsters, slipper lobsters, spiny lobsters) but lack the iconic large claws of true lobsters.

Continuous growth

Lobsters grow throughout their lives — they never stop growing. The growth is achieved through molting:

  • Shedding old shell every few years (more often in young animals)
  • Body expanding while shell is soft
  • New shell hardening over weeks
  • Growth continues for life

Some old lobsters reach 10-15+ kg in sheltered cold waters. The largest verified American lobster weighed 20.1 kg (caught in Nova Scotia, 1977).

Possibly biologically immortal

Lobsters exhibit negligible senescence — they don’t appear to age in the way most animals do:

  • Reproductive capability increases with age
  • Telomerase activity remains high throughout life
  • No documented “old age” diseases
  • Death typically from external causes: shell disease, predation, fishing, molting failures

This has led to claims of biological immortality — though that’s an overstatement. Lobsters do eventually die, but the death is typically from environmental factors rather than aging.

The longest-lived documented lobsters have lived 140+ years in cold protected waters.

Mating dance

Lobster mating involves an elaborate courtship:

  • Females select a male’s territory
  • Female enters male’s burrow during her receptive period (just after molting)
  • Males protect females during their vulnerable post-molt softness
  • Pair-bonding lasts about a week
  • Males then return to solitary life

The mating system is unusual — most invertebrates don’t have any pair-bonding behavior. Lobster pair-bonds are short but real social relationships.

Sustainable fishery success

The American lobster fishery is a remarkable sustainability success:

  • Legal minimum size prevents catching juveniles
  • V-notch program protects breeding females
  • Trap-only fishing (no nets, lower bycatch)
  • Limited entry licensing controls effort
  • Population stability maintained for decades

The Maine lobster fishery is among the most carefully managed wild fisheries globally. Population assessments show healthy or growing populations in most regions.

Maine vs Canadian harvest

Maine produces about 50% of US lobster harvest but Atlantic Canada actually produces more lobster than the US:

  • Maine — 50,000-60,000 tons annually
  • Atlantic Canada — 50,000-80,000 tons annually
  • Massachusetts, New Hampshire, etc. — additional 10,000-15,000 tons

Atlantic Canadian lobster is generally similar to Maine lobster (same species), but legal sizes and seasons differ between jurisdictions. Most premium restaurants and exporters source from both regions interchangeably.

Climate change concerns

Despite recent population health, climate change is affecting lobster populations:

  • Southern New England population collapse (2000s-present) — warming waters
  • Maine population shift — moving north to colder waters
  • Atlantic Canada increasing — lobsters migrating into newly suitable waters
  • Shell disease prevalence — increasing with warming
  • Long-term outlook uncertain for southern range

The fishery’s economic future depends substantially on how warming progresses and whether lobsters can continue migrating to maintain populations.

The clawed claws

American lobsters have two distinct claws:

  • Crusher claw — larger, slower, used for breaking hard prey
  • Cutter (pincer) claw — smaller, faster, used for cutting meat

Each lobster develops crusher and cutter on different sides — about 50% are right-hand crushers and 50% left-hand crushers. The claw asymmetry develops in juvenile lobsters and is permanent.

Ethical concerns

Modern lobster preparation raises ethical questions:

  • Live boiling — traditional but increasingly questioned
  • Pain perception — research suggests lobsters can feel pain
  • Switzerland (2018) banned boiling live lobsters
  • Italy and several jurisdictions require humane killing methods

Alternative humane killing methods include electrical stunning, freezing, or mechanical destruction of nervous system. These approaches are increasingly required by some commercial operations and welfare-conscious home cooks.
