Distribution Of Shell-Boring Polychaetes At Shellfish Aquaculture Sites Along The Northeast Coast Of The Us, Samantha Silverbrand
Distribution Of Shell-Boring Polychaetes At Shellfish Aquaculture Sites Along The Northeast Coast Of The Us, Samantha Silverbrand
Honors College
Coastal shellfish aquaculture has expanded substantially in recent years in Maine and New England as traditional wild fishery stocks have declined. As shellfish aquaculture has expanded, producers have become more concerned about marine worm pests (i.e., polychaetes) that infest cultured bivalves. In particular, worms from the genus Polydora (also known as “polydorids”) burrow into oyster and scallop shells where they feed and deposit mud. Bivalves cover over the muddy burrows creating blisters that can decrease their market value and hinder growth. Farmers and researchers have identified methods to control infestations of P. websteri, one common species of shell-boring worm. However, …

Maine Lobstermen's Association Whale Update, Amber-Jean Nickel, Maine Lobstermen's Association
Fisheries
The Maine Lobstermen's Association “has been closely following the death of Right Whale 5120 found dead on Martha’s Vineyard on January 28th. The MLA was shocked and dismayed when NOAA Fisheries announced on February 14th that the rope removed from the deceased whale 'is consistent with the rope used in Maine state water trap/pot buoy lines.’”
“Maine lobstermen have made many changes to how we fish to avoid harming a Right whale which makes this news hard to believe. As we move forward, MLA will push back on NOAA’s finding until the industry’s questions about the entanglement and how NOAA …

Unbridled Insights: Exploring Equine Behavior Through Gps Tracking And Analysis, Madison L. Philbrick
Electronic Theses and Dissertations
Horse behavior in pasture and grazing environments remains understudied, despite the substantial domestic horse population in the United States. This paper explores the utilization of Global Positioning System (GPS) technology to detect equine behavior, specifically focusing on grazing behaviors. By analyzing GPS data from (n=9) Standardbred horses, this study aims to establish the capabilities and accuracy of the Columbus P-1 data logger as a low-cost GPs unit for equine research, without the use of accelerometers. Through the data provided by the GPS unit, a model to distinguish grazing, resting, drinking, walking, trotting, and running was developed with satisfactory detection rates. …

Assessing The Role Of The Microbiome, Parasite Infections, And Movement In Avian Health, Olivia N. Choi
Electronic Theses and Dissertations
Avian health encompasses the physical, physiological, and behavioral well-being of birds. Assessing avian health is not only important for the conservation and management of wild birds and the recreational economy, but also for the management of infectious diseases that threaten public health and agriculture. Birds, comprising approximately 10,000 species and an estimated 50 billion individuals worldwide, are known to be involved in the spread of pathogens, some of which are zoonotic (from animals to humans), such as avian influenza and West Nile viruses. Individual measures of avian health may include physical measurements (e.g., body mass, wing length), pathogen infection status, …

The Sociocultural Significance Of Maine's Oyster Based On Media Coverage Analysis, Syeira Clark
Honors College
Throughout the last decade, the oyster aquaculture industry in Maine has boomed, with 6 million pounds of oysters being harvested in 2021, about the amount that was harvested in 2016 (Cough, 2022). According to the founders of the Maine Oyster Trail, there are over 150 oyster farms currently operating on Maine’s coast, which is about twice as many as there were in 2016 (Maine Sea Grant). With this boom in the industry has come a wave of opportunity, as well as news coverage about the shellfish. This study examines the socio-cultural significance to the state of Maine. While the oyster …

Effects Of Wilting Extent On The Phytoestrogen Levels, Nutritional Value, Microbial Populations, And In Vitro Ruminal Methane Emissions Of Red Clover Hay And Silage Across Stages, Diego Zamudio Ayala
Effects Of Wilting Extent On The Phytoestrogen Levels, Nutritional Value, Microbial Populations, And In Vitro Ruminal Methane Emissions Of Red Clover Hay And Silage Across Stages, Diego Zamudio Ayala
Electronic Theses and Dissertations
The main objective of this thesis is to improve the understanding and awareness of methodologies to decrease phytoestrogens in conserved legumes without sacrificing forage nutritive value. In chapter 1, we discussed the main factors influencing each stage of hay production and our current understanding of the hay microbiome dynamics. The primary objective of haymaking is to dry forage enough (80-85% DM) to inhibit the growth of undesirable microbes and halt residual plant enzymatic activity that causes nutrient losses. During the field and storage phases of haymaking, the environment, management practices, and other factors influence the extent of DM losses. This …
Collaborative And Engaged Research To Strengthen Equity And Adaptive Governance In Co-Managed Fisheries, Gabrielle V. Hillyer
Collaborative And Engaged Research To Strengthen Equity And Adaptive Governance In Co-Managed Fisheries, Gabrielle V. Hillyer
Electronic Theses and Dissertations
Small-scale, co-managed fisheries are found throughout the world and often represent intertwining cultures, societies, communities, economies, institutions, and governments. They face complex issues, derived from ecological and social sources. Solving these issues requires diverse expertise, often developed through engaged methodologies which can facilitate collaborative solution creation between researchers, community members, and others. In this dissertation, I demonstrate the benefits of these engaged methodologies and review how they, when coupled with anticolonial approaches to research, can create more equitable solutions to complex issues. This dissertation focuses on multiple projects within the wild clam fishery in Maine including: (1) the creation of …

Biophysical Factors Impacting Sea Lice Settlement And Survival, Eleanor R. Glahn
Biophysical Factors Impacting Sea Lice Settlement And Survival, Eleanor R. Glahn
Electronic Theses and Dissertations
Atlantic salmon (Salmo salar L.) aquaculture production in Maine is a valuable contributor to the economy, the expansion of which has been challenged by the parasitic salmon louse Lepeophtheirus salmonis. As planktonic organisms, the life of the salmon louse is primarily dictated by the physical conditions of the environment: the temperature for development time, salinity for survival, and current velocity for transport. Salmon lice are obligate parasites for whom the successful infection of a suitable host is critical to completion of their life cycle. However, little is understood about the effects of current velocity on infection success. Hydrodynamic …

Post-Harvest Treatment Effects On Physicochemical Quality Attributes Of North Atlantic Squid Doryteuthis Pealeii And Illex Illecebrosus, Caitlin M. Hillery
Electronic Theses and Dissertations
Doryteuthis pealeii (longfin inshore squid) and Illex illecebrosus (Northern shortfin squid) are the two most commercially important species of squid harvested in the United States. They are also the only two species of squid in the world certified sustainable by the Marine Stewardship Council. Despite their pivotal role in the U.S. seafood industry, very little research has been performed on their quality in decades. Two common methods of freezing and secondary processing applied to squid in the U.S. industry are blast-freezing either at sea or on land; and leaving the squid whole, or fully cleaning and then brining them. To …

Endothermy allows species to decouple body temperature from environmental
temperatures but does not equate to endothermic species maintaining those constant temperatures. Instead, heterothermy fluctuating body temperatures, both in and outside of torpor is common and allows endotherms to expand the limits of thermoneutrality. Thermolability is likely to be more common in the tropics and subtropics, where species live within or above their thermoneutral zone. My dissertation research focused on the heterothermic-homeothermic continuum, specifically quantifying where on the continuum different species fall at certain times and why those species have evolved to be at those points. I quantified the thermal profile …
Optimizing Strategies To Hydraulically Plant Atlantic Salmon Eggs Based On Fry Dispersal Patterns, Ernest J. Atkinson
Optimizing Strategies To Hydraulically Plant Atlantic Salmon Eggs Based On Fry Dispersal Patterns, Ernest J. Atkinson
Electronic Theses and Dissertations
The Gulf of Maine Distinct Population Segment of Atlantic Salmon has suffered from habitat loss and exploitation over the last century. Hatchery supplementation has prevented the extirpation of the species, but stocking methods represent tradeoffs between survival, domestication, and logistics. Egg planting, the use of eyed embryos, maximizes natural rearing opportunities which can be important for adaptation. This method, however, is logistically demanding and requires significant labor over large spatial, but short temporal, scales dictated by the ontogeny of the fish. However, the survival and dispersal behavior of Atlantic Salmon fry immediately after emergence from eggs planted in artificial nests …

Expression Of The Rag-1 Gene In Larval Yellowtail Kingfish, Gabriella Peluso
Honors College
Aquaculture has taken over from capture fisheries as a primary global provider of seafood products. Seriola lalandi, or Yellowtail kingfish, has become a species of interest, as it is a fish notable for its marketability and culinary desirability. With the expansion of aquaculture and the increased amount of high-level operating facilities comes an increased risk of disease outbreaks. There are methods commonly used within these facilities for disease control, including incorporating nutritional feeds into the fishes’ diets, safe husbandry practices, and vaccinations. While these methods can be effective, they have caveats that must be considered. Adequate diets and improved …

I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy
Honors College
Littorina littorea is an intertidal, invasive gastropod species common in the Gulf of Maine. In this paper, I studied the avoidance and risk-reducing behavioral responses of L. littorea to predation risk by invasive crustacean species Carcinus maenas. Avoidance and risk-reducing behavior in this study are defined by the tendency to move towards the edge and out of a simulated tide pool and the tendency to reduce feeding. The goal of this study was to determine whether the exposure to chemical cues of predators resulted in an increase in avoidance behavior, risk-reducing behavior, and a reduction in the time before the …
