The american lobster is the most valuable fishery in the U.S. And represents a fishery that has shown a history of inconsistent biological stock definition and climate change impacts

This Cooperative Agreement award from the National Oceanic and Atmospheric Administration (NOAA) under the Sea Grant Support program (CFDA 11.417) provides $416,369 to the Gloucester Marine Genomics Institute Incorporated (GMGI) to conduct a genomic population structure evaluation on the American lobster. The project aims to assemble an improved lobster genome, collect 550 lobster tissue samples from 22 locations in New England and Canada, assess the genetic population structure and environmental adaptations, and share the results with the Atlantic States Marine Fisheries Commission to improve stock management. The award period is from October 1, 2024 to September 30, 2026. The outcomes will include an enhanced lobster genome, high-quality genetic data on the lobster population, and a better understanding of how lobsters are adapting to changing environmental conditions, which will aid future research and sustainable management of this valuable fishery.

The purpose of the project is to conduct a genomic population structure evaluation on american lobsters collected throughout the gulf of maine, georges bank, and southern new england to establish biologically accurate stock boundaries. Project activities will include 1) assembling an improved lobster genome, 2) collaborating with commercial lobstermen and regional lobster biologists to collect a total of 550 lobster tissue samples from 21 locations throughout new england and one canadian location, 3) assessing the lobster genetic population structure and responses to environmental conditions recorded in the genome, 4) sharing results with the atlantic states marine fisheries commissions american lobster technical committee and soliciting feedback to improve stock boundaries and management strategies. Project outcomes will include an improved lobster genome assembly, high-quality genetic population structure data for lobster in new england, and a better understanding of how lobsters are adapting to shifting environmental conditions. Project results will aid in future investigations of lobster biology and contribute to the sustainable management of lobster for the benefit of the fishing industry, researchers, and the public.
