About Lobster Conservation
Dedicated to the science, management, and preservation of the American lobster (Homarus americanus) species and their marine environments.
Our Mission
At Lobster Conservation, our mission is to bridge the gap between scientific research and practical application. We believe that sustainable fisheries and healthy marine ecosystems are built on a foundation of knowledge.
We strive to provide accurate, accessible, and up-to-date information on lobster biology, fishery management strategies (overseen by organizations like the Atlantic States Marine Fisheries Commission (ASMFC)), and conservation status. By empowering educators, industry professionals, and the public with this knowledge, we can work together to ensure thriving lobster populations for generations to come.
Key Lobster Statistics & Data
| Statistic/Metric | Value | Source/Context |
|---|---|---|
| Annual Maine Harvest | 110 million pounds | Valued at approximately $740 million. Maine is the epicenter of the American lobster industry. |
| Gulf of Maine / Georges Bank Stock Trend | 34% Decline (since 2018) | Per ASMFC 2025 benchmark stock assessment. The stock is not depleted, but overfishing is occurring. |
| Optimal Temperature Range | Below 20°C | Warming oceans are reducing populations of American lobsters which prefer cooler temperatures. |
| Shell Disease Prevalence | Epizootic shell disease (ESD) | Associated with a polymicrobial infection, characterized by shell erosion, pitting, and melanization. Exacerbated by rising water temperatures. |
Frequently Asked Questions
Who manages the American lobster fishery?
The American lobster (Homarus americanus) resource and fishery in the U.S. is assessed and managed by the Atlantic States Marine Fisheries Commission (ASMFC).
What is the current status of the Gulf of Maine / Georges Bank lobster stock?
According to the ASMFC 2025 benchmark stock assessment, the Gulf of Maine / Georges Bank stock is not depleted, but overfishing is occurring. The stock has seen a 34% decline since 2018.
Where are American lobsters found in the US?
The American lobster is found along the Atlantic coast of North America, from Labrador to New Jersey. Maine is considered the epicenter, boasting over 110 million pounds of American lobster annually, valued at approximately $740 million.
How do climate change impacts and ocean acidification threaten the American lobster?
Warming oceans are reducing populations as American lobsters prefer temperatures below 20°C. Additionally, rising water temperatures and environmental pollution are contributing factors to Epizootic shell disease (ESD), which degrades the shell and can be fatal.
What We Do
- Scientific Communication: We translate complex marine biology research into clear, understandable guides for non-scientists.
- Fishery Support: We provide summaries of regulations and best practices to help fishers operate sustainably and legally.
- Educational Outreach: We develop curriculum materials and field kits for teachers and community leaders to inspire ocean stewardship.
- Data Aggregation: We compile data on population trends and environmental threats to present a clear picture of the state of lobster conservation.
