Population Dynamics Of The Sub-Arctic Copepod Calanus Finmarchicus In The Gulf Of Maine: Demography And Mortality Estimation, Cameron R. S. Thompson

Electronic Theses and Dissertations

Calanus finmarchicus is a widely distributed copepod species that dominants the zooplankton community in the Gulf of Maine. It is of particular interest in its role as a major food source for the endangered northern right whale and stocks of herring, mackerel and cod. More accurate coupled models to predict its distribution requires better life history models. However, due to the difficulty in estimating it, mortality is often used as a closure term in those models; the value is justified mathematically rather than ecologically. Instantaneous mortality is difficult to measure, but the Vertical Life Table method (VLT) has gained some …

Gentrification And Vulnerability Of Maine Fishing Communities, Cameron R. S. Thompson

Electronic Theses and Dissertations

Maine hosts numerous small fishing villages that contribute greatly to the States economy and culture. The cumulative effects of state and federal regulation, stock depletion and other socio-economic trends threaten these communities. Drawing on ethnographic research and interviews, we examine how gentrification is affecting the vulnerability and resilience of fishing communities. This study has revealed gentrification to be a complex process, which is merely the most readily recognizable symptom of forces that are reshaping the post-industrial landscape. Fishing communities can no longer be thought of as discrete entities isolated from broad social and economic changes. Technology and new markets have …

Characterizing Fish Assemblage Structure In The Penobscot River Prior To Dam Removal, Ian Andrew Kiraly

Electronic Theses and Dissertations

The Penobscot River drains the largest watershed in Maine, and once provided spawning and rearing habitats to at least 11 species of diadromous fish. The construction of dams blocked migrations of these fish and likely changed the structure and function of fish assemblages throughout the river. Further alteration to fish assemblage structure likely occurred as a result of habitat fragmentation and alteration. The proposed removal of two main-stem dams, improved upstream fish passage at a third dam, and construction of a fish bypass on dam obstructing a major tributary is anticipated to increase passage of diadromous and resident fishes. To …

Marine Ecology Of Gulf Of Maine Atlantic Salmon -- Summary Document From A 2008-2010 Series Of Workshops, Maine Sea Grant

Maine Sea Grant Publications

Present-day Atlantic salmon losses at sea are higher than documented prior to 1990 but scientists and managers are often overwhelmed at the scale of the issue and multiple unknowns. This is confounded by the small biomass of salmon in a large ecosystem-- a needle in a haystack.

Maine Sea Grant provided convening and facilitation services to a project sponsored by NOAA Fisheries to bring together marine scientists of multiple disciplines to discuss and develop:

1) testable hypotheses to advance our understanding of current low marine survival of Atlantic salmon and

2) management prescriptions to increase marine survival. A series of …

Maine Sea Grant: Facts At A Glance 2012, Maine Sea Grant

Maine Sea Grant Publications

Maine Sea Grant supports scientific research that is relevant to the issues and needs of coastal communities in Maine and the northern Gulf of Maine region. Research in our program is accomplished in three ways, which are often connected:

(1) competitive research grants from both Maine research funds and national solicitations;
(2) program development grants to investigators in the state and region; and
(3) research activities of the Marine Extension Team.

Reaching Into The Past For Future Resilience: Recovery Efforts In Maine Rivers And Coastal Waters, John Lichter, Ted Ames

Maine Policy Review

John Lichter and Ted Ames discuss how analysis of environmental histories of human activities affecting Maine’s estuary, river, and coastal marine ecosystems can shed light on the role key fish species may play. Through Maine’s Sustainability Solutions Initiative, a group of researchers from Bowdoin, Bates, Univer­sity of Southern Maine, and Penobscot East Resource Center have teamed up to examine ecological recovery in the state’s waterways and coastal fisheries. Several river restoration efforts were already underway, and others are being planned as a direct result of this inter­disciplinary project.
