Dietary Shifts And The Need For Increased Sustainability Approaches In The Global Aquaculture Seafood System, Darien D. Mizuta

VIMS Articles

Recent shifts in the global dietary preferences have indicated the fast-growing choice for plant-based, or meat-reduced diets. Among the motivations for such choices, which are increasingly advocated by nations and environmental institutions, is the major concern with global environmental sustainability and impacts of food production systems. Incontestably, the animal food source industry is extremely diverse, and seafood production through the aquaculture value chain remains unfamiliar to key stakeholders possibly leading to an uncomprehensive view and often biased perception of the farming industry within the environmental context. Accordingly, I discuss the importance of seafood production systems, such as the fastest seafood …

"Smells Fishy": Exploring Sense Of Place Salience In Community Rejection Of Closed Net-Pen Aquaculture In Frenchman Bay, Maine, Gabriella Gurney

Electronic Theses and Dissertations

The global population is rising, and with it, demand for protein, particularly seafood. Aquaculture, the farming of aquatic species such as finfish, shellfish, and kelp, has been proposed as an alternative to wild-catch fisheries, of which 75% are overfished or at capacity. In Maine, aquaculture is growing, but often faces mixed community response when new or expanded projects are proposed. In the summer of 2020, a large-scale closed net-pen farm for Atlantic salmon (Salmo salar) was proposed for Frenchman Bay, Maine. Community reaction was instantaneous and overwhelmingly negative. The strong, unified response from residents in the towns of …

The Art Of Not Being Freshened: The Everyday Politics Of Infrastructure In The Mekong Delta, Timothy Gorman

Department of Sociology Faculty Scholarship and Creative Works

With the growing threat of climate change, states are increasingly turning to large-scale infrastructure projects in order to control environmental conditions, especially in coastal areas. These projects are often planned and implemented in a centralized, top-down manner and sometimes fail to achieve their stated objectives in the face of “everyday resistance” from local residents and farmers. This study draws on interviews and secondary research to examine the contentious everyday politics of infrastructure in the Mekong Delta region of Vietnam, focusing specifically on how small-scale, surreptitious acts of “counter-infrastructuring” on the part of farmers, such as the construction of illicit wells …

Aquaculture Extension Capacity In The Usda North-Central Region: Results From A Survey, J. Stuart Carlton, Amy M. Shambach, Kwamena Quagrainie

Journal of Human Sciences and Extension

We surveyed Agriculture and Natural Resources Extension staff across the USDA North-Central Region about aquaculture programming. Overall, 47%, 35%, and 15% of respondents indicated that stakeholders had contacted them about aquaponics, finfish aquaculture, and shrimp aquaculture, respectively. Approximately 8% of respondents indicated that they offered aquaculture or aquaponics programming; 45% and 55% indicated that they did not offer aquaculture and aquaponics programming, respectively, but were interested in offering it. These results indicate that there is interest in increasing Extension capacity in fish farming either by hiring new staff or through train-the-trainer models.

Developing Sustainable Aquaculture At Scale, Shauna A. Bulger

Dartmouth College Master’s Theses

Abstract

The United Nations Food and Agriculture Organization (FAO) reported that commercial aquaculture production has outpaced wild fisheries since 2013, and in 2018, aquaculture became the fastest growing food production sector in the world (FAO SOFIA, 2018). Wild fishery landings have not meaningfully increased since the 1980s. As a result, international development organizations and environmental non-governmental organizations (ENGOs) have pitched the industry as a sustainable alternative to wild fisheries and the most promising option for the future of seafood production. Governance and transition scholars, however, are skeptical about if and how the presumed benefits of the fisheries-to-aquaculture will materialize for …

Monitoring Bull Kelp (Nereocystis Leutkeana) Remotely At High Resolutions, Hannah E. Joss

Cal Poly Humboldt theses and projects

Bull kelp (Nereocystis leutkeana) is a foundational seaweed in nearshore, marine systems, traditionally supporting economically important fisheries, extracting nutrients in its vicinity, and sequestering carbon and transporting it great distances to subsidize shallow and deep-sea environments. Bull kelp is also a culturally important species for some indigenous peoples along the northeastern Pacific coastline and provides a harvestable product with growing demand. Global trends in kelp distribution show patterns of decline, and the immense loss of northern California bull kelp forests in response to climatic changes have highlighted the need for alternative sources of kelp, both for the product …

Reflections On A Career Unplanned, Robert A. Glazer

Gulf and Caribbean Research

Sometimes life takes unexpected turns. I never planned to be a marine biologist; yet, after a long and unpredictable journey, that’s exactly where I found myself. After obtaining my B.S. in Fishery Biology from Colorado State University, I found myself meandering from job to job like a golden retriever following some vague scent. At first, I was hired by the Wyoming Game and Fish Department to work seasonally in Grand Teton National Park on the freshwater trout fisheries. Soon thereafter, I found myself cultivating oysters, clams, and other shellfish in California. The skills I developed there as an algologist led …

Is Aquaculture A Path To Community Resilience In Maine?, Benjamin J. Cotton, Caroline L. Noblet, Bruce Wyatt, Keith S. Evans, Mario F. Teisl

Maine Policy Review

Coastal towns across Maine face a number of challenges maintaining resilience, posing a threat in their response to disaster. Aquaculture has been presented as a potential solution for some coastal communities; however, the question of ‘fit’ is a source of debate within Maine. Decision-makers may seek further understanding of citizens’ perceptions of their community’s resilience and marine aquaculture, including preferences for supporting growth of the sector across the state's coastal region. To provide this information, we analyze data from a survey of Maine citizens. We assess residents’ perceptions of community resilience and whether marine aquaculture supports resiliency goals along the …

Aeromonas Phage Research And The Public Health Impact Of Antibiotics In Aquaculture Workers, Madelyn Merchant

Honors Projects

One of the most common fish diseases in aquaculture is Aeromonas infection. The most common way to treat this infection is through antibiotics. The bacteria in the fish can become antibiotic-resistant and perpetuate the disease. The diseases in fish create a huge financial loss and the industry loses $6 billion per year due to diseases in fish. An alternative to antibiotics is bacteriophage which causes less environmental degradation and is better for human gut flora. In aquaculture there have been examples of aquaculture workers becoming sick from the water in aquaculture ponds as well as from people eating the fish. …

Blue Growth: A Transitions Approach To Developing Sustainable Pathways, Christina Kelly, Ben Mcateer, Frances Fahy, Liam Carr, Daniel Norton, Desiree Farrell, Rebecca Corless, Stephen Hynes, Zacharoula Kyriazi, Agnès Marhadour, Regis Kalaydjian, Wesley Flannery

Journal of Ocean and Coastal Economics

The sustainable management of Blue Growth is an urgent issue for coastal states. Marine industries have rapidly expanded over the last two decades and this is projected to continue with the European Green Deal and post-COVID economic recovery policies. The intensification of Blue Growth could have adverse socio-ecological implications and must, therefore, be managed in terms of sustainability, natural resource boundaries, and coastal community well-being. Managing Blue Growth in a sustainable manner however, is challenging due to the longstanding inefficiencies and inertia of existing marine governance regimes. Adopting a transitions approach has been advanced as a way of steering regime …

Sentience Politics : A Fishy Perspective, Culum Brown

Animal Sentience

The plight of fishes has almost certainly got worse since Bentham (1789) coined the phrase “The question is not Can they reason? nor, Can they talk? but Can they suffer?” Despite the fact that fishes are increasingly recognised as sentient animals worthy of protection under animal welfare legislation in many countries around the world, fishing practices are almost universally exempt activities. The human population continues to grow, and, surprisingly, per capita intake of fish is still increasing (FAO 2020). The source of this fish is not wild stocks (catches of which have remained more or less stagnant for …

Behavioral Patterns Of Goldfish (Carassius Auratus) Exploring A “Fish Tower”, Sasha Prasad-Shreckengast

Theses and Dissertations

Fish are held in captivity at some of the highest numbers of any taxa, but their curiosity is rarely studied. With this study, we set the groundwork to investigate the presence and nature of curiosity in goldfish (Carassius auratus) via novel free-choice exploration opportunities by creating a “fish tower."

The Effects Of Probiotic Therapy On Stress Coping Styles Of Triploid Juvenile Farmed Chinook Salmon, Oncorhynchus Tshawytscha, Brendyn M. St. Louis

Electronic Theses and Dissertations

Triploid salmon – fish with three sets of chromosomes – are regularly used in aquaculture as they are functionally sterile and therefore avoid the decline in flesh quality associated with sexual maturation. However, triploid fish exhibit many immune, behavioural, and physiological drawbacks which reduce their condition and survival in aquaculture environments. My research examines the effects of probiotic treatment to promote behavioural and stress-related (termed ‘coping styles’) traits more suited for aquaculture environments in triploid fish with the ultimate goal of increasing fish yield. In this study, Chinook salmon (Oncorhynchus tshawytscha) crosses were developed in a 3x3 and 3x2 design, …

Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler

The Cardinal Edge

This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …

Marine Aquaculture In Maine: Understanding Diverse Perspectives And Interactions At Multiple Scales, Melissa L. Britsch

Electronic Theses and Dissertations

Coastal oceans are changing and experiencing increased use. The social and ecological benefits of healthy coastal oceans are well documented and include habitats for marine species, storm protection, and recreational opportunities (MEA, 2005). As the impacts of human activities are recognized, questions about how ocean spaces should be used are becoming more common. These questions are complex and involve many tradeoffs. Understanding the values people hold about uses, and how activities and ecosystems overlap, is critical for weighing tradeoffs and improving future management. I use the northeastern U.S. state of Maine to study human interactions with coastal oceans. Maine is …

Internet Of Things Based Messaging Protocols For Aquaculture Applications - A Bibliometric Analysis And Review, Rupali Shete, Anupkumar M. Bongale Dr., Arunkumar Bongale Dr.

Library Philosophy and Practice (e-journal)

Internet of Things (IoT) which connects real-world physical objects with various identities involves different technologies and research areas. As it is an integration of different standards and technologies with numerous capabilities, the implementation phase needs to consider important parameters of communication. In IoT this is achieved through messaging protocols. Each object has its own limitations in terms of sensing capability, storage capacity, connectivity, power utilization, etc. And hence when such objects are deployed for different applications, they need to perform well in terms of their various capabilities. Messaging protocols at this stage need to consider these diverse elements. One of …

Fishing And Rural Livelihood: A Philippine Context, Rosalina Palanca-Tan, Sheila Bongat-Bayog

Economics Department Faculty Publications

The Municipality of Lake Sebu in Mindanao; Philippines offers various opportunities for income-generating fishing activities with its abundant surface water bodies. Lake Sebu is particularly known for good quality tilapia; farmed in fish cages. This study employed primary data collection methods; namely key informant interview; focus group discussion and a comprehensive livelihood household survey to assess the conditions and problems constraining fishing households in Lake Sebu. The study found that fishing-related benefits were mainly derived from aquaculture. Capture fisheries are essentially very small-scale; low gear open fishing done by local fisher folk that generates only subsistence income. Local residents are …

Economic Vulnerabilities Of Fishing-Dependent Households Around Laguna Lake, Philippines, Rosalina Palanca-Tan

Economics Department Faculty Publications

The study characterizes the mainly subsistence fishing communities surrounding Laguna Lake and provides empirical evidence of the economic deprivation that they are experiencing using survey data. Following a multi-dimensional approach, the paper focuses on consumption expenditures as the prime indicator of economic well-being – together with assets ownership, financial behavior, and social engagements. Regression analyses are conducted to identify the factors underlying consumption and to determine how different forms of household capital (physical, financial, and social) and fishing activities affect the capacity to generate income or livelihood. The study finds that: 1) food consumption (mainly rice) accounts for half of …

The Influence Of Message Type, Environmental Attitude, And Political Ideology On Perceptions Of Aquaculture In The United States, Tabitha C. Boze

Electronic Theses and Dissertations

In the United States, aquaculture receives varying degrees of support based on individuals’ perceptions of the industry. This study analyzes the factors that contribute to those perceptions; namely, message type, affect, political orientation, and environmental attitude. We collected data through a nationwide survey, distributed by Qualtrics, which recruited a representative sample of U.S. residents. The survey included multiple-choice, Likert scale, and open-ended questions regarding individual characteristics (e.g., age, income, political orientation, etc.) and opinions on aquaculture. In order to study message type, we employed four experimental conditions (narrative video, narrative text, infographic video, and text) and one control group with …
