Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level. Rapid environmental changes typically cause mass extinctions. The age of the Earth is about 4. There are microbial mat fossils found in 3. Since life began on Earth , five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. In the Carboniferous , rainforest collapse led to a great loss of plant and animal life. The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity.

It began with the Native American tribes who celebrated annual fish runs, and continued with colonial settlers, whalers, and the modern fishing fleet.

Fishing still defines our culture today, with lobsters, sea scallops, crabs, and a variety of fish filling our menus and attracting tourists from all over the world. New Bedford, Massachusetts, is consistently among the highest value ports in the United States, thanks to the lucrative scallop fishery. Recreational fishing is a popular pastime, contributing billions to our economy. Many fishermen still fish in the same places and for the same species as their ancestors hundreds of years ago. We are also dedicated to conserving, protecting, and rebuilding endangered and threatened marine and anadromous species in rivers, bays, estuaries, and marine waters off New England and the Mid-Atlantic.

Our work to maintain sustainable fisheries and protect marine life is a joint effort of the Greater Atlantic Regional Fisheries Office and Northeast Fisheries Science Center, offering sound science to help inform management decisions in an ever-changing environment. Since then, our research has promoted recovery and Riverss sustainability of marine life in the region and sustaining coastal communities. Through our comprehensive marine science program, we study fishery species and fisheries, monitor and model ocean conditions and habitats, develop aquaculture, and provide reliable advice for policymakers.

We work cooperatively with the New England and Mid-Atlantic Fishery Management Councils, and the Atlantic States Marine Fisheries Commission to develop, review, and implement fishery management plans in federal waters from 3 to nautical miles. Our research and research surveys provide the necessary information needed to evaluate the overall health of more than 50 fisheries with 14 fishery management plans in our region, from Maine to North Carolina, an area about the size of California. We are dedicated to research management to conserve, protect, and rebuild endangered and threatened marine and anadromous species in rivers, bays, estuaries, and marine waters of the Northeast and Mid-Atlantic.

Our work helps ensure the survival of protected marine species for future generations. Healthy habitats are Diveraity foundation of healthy fisheries. We work to protect, conserve, and restore habitats for fishery resources under our stewardship. We also conduct research on marine life to determine how habitat loss, degradation, restoration, and mitigation affect ecosystems. Our vision is for healthy and self-sustaining coastal and marine habitats that support vital ecosystem functions, including abundant living marine resources, human uses, and resilient coastal communities.

We work cooperatively with a wide variety of federal, state, and local agencies and non-governmental organizations to protect and restore habitat to sustain fisheries, recover protected speciesand maintain resilient coastal ecosystems and communities. We manage 42 commercial and recreational fish and shellfish for sustainable use. We protect and conserve dozens of marine mammal, sea turtle, and endangered fish species from Maine to North Carolina.
