Investigating Present-Day Health Issues Of The American Lobster (Homarus Americanus), Deborah A. Bouchard May 2018

Investigating Present-Day Health Issues Of The American Lobster (Homarus Americanus), Deborah A. Bouchard

Electronic Theses and Dissertations

The American lobster, Homarus americanus, H. Milne Edwards, 1837, supports the most economically valuable fishery along the North Atlantic coast of North America. A collapse in lobster populations in Southern New England (SNE) has coincided with increasing ocean temperatures and emerging diseases. This research investigated the etiologies of limp lobster disease (LLD) and epizootic shell disease (ESD), two diseases that continue to cause significant mortality in natural lobster populations. Mortality from LLD is associated with the bacteria Photobacterium indicum and is more intense in impounded lobsters. To more clearly define the community ecology of this suspected opportunistic pathogen, the microbial ...


Spatio-Temporal Dynamics Of Atlantic Cod Bycatch In The Maine Lobster Fishery And Its Impacts On Stock Assessment, Robert E. Boenish May 2018

Spatio-Temporal Dynamics Of Atlantic Cod Bycatch In The Maine Lobster Fishery And Its Impacts On Stock Assessment, Robert E. Boenish

Electronic Theses and Dissertations

Of the most iconic fish species in the world, the Atlantic cod (Gadus morhua, hereafter, cod) has been a mainstay in the North Atlantic for centuries. While many global fish stocks have received increased pressure with the advent of new, more efficient fishing technology in the mid-20th century, exceptional pressure has been placed on this prized gadoid. Bycatch, or the unintended catch of organisms, is one of the biggest global fisheries issues. Directly resulting from the failed recovery of cod in the GoM, attention has been placed as to possible sources of unaccounted catch. Among the most prominent is ...


Incorporating Environmental Variability Into Assessment And Management Of American Lobster (Homarus Americanus), Kisei Tanaka May 2018

Incorporating Environmental Variability Into Assessment And Management Of American Lobster (Homarus Americanus), Kisei Tanaka

Electronic Theses and Dissertations

The American lobster (Homarus americanus) support one of the most valuable fisheries in the United States. A growing body of literature recognizes the importance of environmental variables in regulating this species’ biogeography and population dynamics. However, the current lobster stock assessment and management do not explicitly consider the impact of environmental variables such as water temperature and assumes spatiotemporal variabilities in the lobster environment as random background noises. Furthermore, while climate-induced changes in marine ecosystems continue to impact the productivity of lobster fisheries, studies that model lobster response to altered environmental conditions associated with climate change are lacking. As such ...


Twenty-Five Years Of Change In Spruce Grouse Occupancy At Their Southern Range Margin In Maine, Usa, Christopher J. Gilbert May 2018

Twenty-Five Years Of Change In Spruce Grouse Occupancy At Their Southern Range Margin In Maine, Usa, Christopher J. Gilbert

Honors College

Species at their southern range margin are often dispersed throughout fragmented populations where they experience less optimum conditions compared to their central range. Spruce Grouse (Falcipennis canadensis) are boreal forest obligates distributed throughout the Northern United States and Canada and reach their southeastern range extent in Maine. I resurveyed 18 Black Spruce (Picea mariana) – Tamarack (Larix laricina) stands on Mount Desert Island, Maine, to observe changes in Spruce Grouse occupancy and abundance between the early 1990s (Whitcomb et al. 1996) and present day. I conducted two rounds of call back surveys within each stand from April to May, 2017. I ...

Sea Lamprey (Petromyzon Marinus) As A Functional Link Between Marine And Freshwater Ecosystems, Daniel M. Weaver Aug 2017

Sea Lamprey (Petromyzon Marinus) As A Functional Link Between Marine And Freshwater Ecosystems, Daniel M. Weaver

Electronic Theses and Dissertations

Anadromous sea lamprey Petromyzon marinus are native to Atlantic coastal systems and serve as a functional link between marine and freshwater ecosystems. Sea lamprey spend 1–2 years in the ocean parasitizing marine vertebrates before migrating into freshwaters during the spring to spawn. There they construct nests, spawn, then die shortly afterwards. Larvae hatch, bury into fine sediments and reside in streams for generally 6–8 years, but up to 14. Larvae then undergo metamorphosis, a non-feeding period characterized by a series of physical and physiological changes. The juveniles (macropthalmia) then migrate to the ocean to begin the parasitic juvenile ...

The 11th International Conference And Workshop On Lobster Biology And Management, Richard Wahle, Kari L. Lavalli Jun 2017

The 11th International Conference And Workshop On Lobster Biology And Management, Richard Wahle, Kari L. Lavalli

Maine Sea Grant Publications

As large, charismatic species, lobsters of all stripes often find themselves at the center of scientific research and in the media spotlight. Lobster fisheries are important economic drivers of coastal communities around the world. Indeed, lobsters are poster children of a marine environment increasingly under the pressures of human exploitation and environmental change. The 200+ abstracts in this program reflect the activity of a vibrant international community of researchers and industry members striving to understand what makes lobsters tick and keep their fisheries sustainable.


Measuring Fertilization In Populations Of Sea Scallop (Placopecten Magellanicus): Developing And Testing Methods In The Laboratory And Field, Skylar Bayer May 2017

Measuring Fertilization In Populations Of Sea Scallop (Placopecten Magellanicus): Developing And Testing Methods In The Laboratory And Field, Skylar Bayer

Electronic Theses and Dissertations

Most marine organisms are broadcast spawners, releasing their sperm and eggs into the water column. Methods of measuring in situ fertilization have proven successful with a few model species, which are reviewed in my introductory chapter. However, many commercially exploited species, such as the sea scallop Placopecten magellanicus, have been neglected. Sea scallop populations have greatly increased from fishing closures, but the mechanism behind this response is uncertain, particularly in regard to fertilization. In this dissertation I developed a methodology of measuring fertilization success and spawning events of P. magellanicus, tested it in laboratory and field settings, and developed a ...


Ecosystem Metabolism Modeling Of Estuaries In Maine: Using Dissolved Oxygen As A Tool For Aquaculture Site Assessment, Katherine Miller May 2017

Ecosystem Metabolism Modeling Of Estuaries In Maine: Using Dissolved Oxygen As A Tool For Aquaculture Site Assessment, Katherine Miller

Honors College

The net primary productivity (NPP), also known as the net ecosystem metabolism, of an estuary is a value indicative of the growth and activity of an estuary’s primary producers, relative to the metabolic activity of its consumers. When NPP is high, estuaries exhibit autotrophic conditions that have the capacity to support fruitful bivalve aquaculture. For oyster farmers, the ability to monitor an estuary’s NPP would allow them to predict and prepare for seasonal changes to oyster growth that result from changes to their phytoplankton food source and access to dissolved oxygen (DO). Not only would this aid farmers ...

Clamming In Maine, Brunswick High School Jan 2017

Clamming In Maine, Brunswick High School

Maine Sea Grant Publications

To become good environmental stewards and gain knowledge of viable economic opportunities, students need opportunities to learn about their local ecosystem and natural resources. The project leader will provide Brunswick High School students with the hands-on experience and curriculum to directly learn about an important local marine habitat and resource. Drawing on curricula from organizations such as the Friends of Casco Bay, Downeast Institute, and the Island Institute, McCullough has designed a monitoring program in which students will take environmental measurements (oxygen, nutrients, temperature, salinity, predation, invasive species, and growth rate); monitor green crab populations; and collect wild oyster spawn ...
