Discover the current status and what it means for the future.
1. What is the American Lobster and Where Does It Live?
Yes, the American lobster, Homarus americanus, can be found in Long Island Sound, although their numbers have declined. These crustaceans inhabit the cold waters of the Northeastern US and Canada, ranging as far south as Virginia. There are three distinct lobster stocks recognized in US waters: the Gulf of Maine (where they are abundant), Georges Bank (stable or increasing populations), and southern New England (where populations have significantly declined in the past decade). Lobsters are fascinating creatures with specific habitat preferences.
1.1 Lobster Habitats and Behaviors
Lobsters are social and territorial crustaceans. They prefer habitats with rocky or firm mud bottoms suitable for burrowing. Research indicates that inshore lobsters, like those in Long Island Sound, exhibit localized movements. Offshore lobsters, however, undertake seasonal migrations from the edge of the continental shelf to inshore waters to spawn in late spring and summer, according to research from the University of Maine’s Lobster Institute. This seasonal movement impacts lobster distribution and abundance in various regions.
2. Why Is Lobster Abundance Important?
Monitoring lobster abundance provides crucial insights into the health of the Long Island Sound ecosystem. Tracking lobster populations offers valuable ecological data, which streetsounds.net uses to inform our community about the environmental status of the Sound. It helps to differentiate between natural population fluctuations and declines caused by external factors like overfishing or habitat degradation.
2.1 Fisheries-Independent Assessment
The standardized catch data from the CT DEEP Long Island Sound Trawl Survey is used to assess the relative abundance of the local lobster stock. This trawl index offers a more precise representation of abundance compared to lobster landings, which can be influenced by factors like fishing gear, fishing frequency, and socio-economic conditions such as market prices. This approach minimizes biases, providing a clearer picture of lobster populations in the Sound.
3. What Is the Current Status of Lobster Populations in Long Island Sound?
The lobster population in Long Island Sound is in decline. Both the fall and spring indices for American lobster show a steady decrease. Since 2003, both indices have remained below the time-series average, and in recent years, they have approached or reached zero.

3.2 Factors Contributing to the Decline
One of the primary factors implicated in the lobster population decline is the increased summer water temperatures in Long Island Sound. American lobsters struggle to maintain their metabolism in waters above 20°C for extended periods. The LISS climate change indicator reveals that Niantic Bay has experienced water temperatures exceeding this threshold during the summer months for the past decade. This temperature stress significantly impacts lobster survival and reproduction.
3.3 Predation and Species Dynamics
The abundance of warm water species that prey on lobsters is increasing in the Sound, such as Black Sea Bass. Other species with high lobster consumption rates, like Smooth dogfish and striped bass, may also contribute to maintaining the current depressed lobster abundance levels. Changes in species distribution and predator-prey dynamics further compound the challenges faced by lobster populations.
4. How Does Climate Change Affect Lobsters in Long Island Sound?
Climate change significantly impacts lobster populations in Long Island Sound, primarily through rising water temperatures. Warmer waters can stress lobsters, making them more susceptible to disease and reducing their reproductive success. These climate-related stressors exacerbate the existing challenges faced by lobster populations, impacting their long-term survival.
4.1 Impact of Water Temperature
American lobsters cannot maintain their metabolism in waters above 20°C (68°F) for long periods. According to the Long Island Sound Study, water temperatures in certain areas have exceeded this threshold consistently over the past decade. This thermal stress weakens lobsters, making them more vulnerable to diseases and predation, thereby contributing to their decline.
4.2 Changes in Species Distribution
As water temperatures rise, warm water species that prey on lobsters are becoming more abundant in Long Island Sound. This shift in species distribution increases predation pressure on lobsters, further diminishing their numbers. The changing ecosystem dynamics present additional challenges for lobster populations to recover.
5. What Data is Used to Track Lobster Abundance?
The CT DEEP Long Island Sound Trawl Survey provides standardized catch data used to assess the relative abundance of the local lobster stock. This survey data is crucial because it offers a fisheries-independent estimation, minimizing biases associated with commercial fishing practices. The survey uses a geometric mean to account for patchy distribution of fish, providing a more accurate representation of abundance.
5.1 Geometric Mean vs. Arithmetic Mean
The survey employs a geometric mean instead of an arithmetic mean to determine the most frequently observed number of fish collected per tow. In a natural environment like Long Island Sound, fish distribution is “patchy,” meaning some areas have high abundance while others have very low abundance or none at all. An arithmetic mean can be skewed by unusually high or low values, misrepresenting the true center of the data set. The geometric mean minimizes the effects of these extreme values using a log transformation, providing a better average for this type of biological data.
5.2 Limitations in Data Collection
In 2020, the CT DEEP Long Island Sound Trawl Survey could not be conducted due to COVID-19 restrictions. Such gaps in data collection can create challenges in tracking trends and understanding the full extent of population changes. The Long Island Sound Study actively seeks data to fill data gaps and ensure the accuracy of the population assessment.
6. What Are the Implications of Declining Lobster Populations?
