Chef Sensory Perspectives And Consumer Acceptance Of Fermented Green Crab Sauce, Bryson J. Mcdonough Aug 2023

Chef Sensory Perspectives And Consumer Acceptance Of Fermented Green Crab Sauce, Bryson J. Mcdonough

Electronic Theses and Dissertations

The European green crab (Carcinus maenas) is an invasive species responsible for immense ecological and economic damage along the Northeastern coast of the United States. Despite multiple population control methods explored, intensive indiscriminate trapping has been the only effective approach However, this type of trapping is currently not financially viable because of the low price and demand for hard-shell green crabs due to their small size and difficult-to-extract crabmeat.

To address this issue, researchers have investigated green crab sauce, a fermented condiment inspired by fish sauce. This umami-enhancing condiment has the potential to raise hard-shell green crab value …


Sustainability Practices In Aquaculture: Using Algae Turf Scrubber Biomass To Raise Black Soldier Flies As An Alternative Feed In Blue Tilapia, Oreochromis Aureus, Culture, Michelle C. Lowery Jan 2023

Sustainability Practices In Aquaculture: Using Algae Turf Scrubber Biomass To Raise Black Soldier Flies As An Alternative Feed In Blue Tilapia, Oreochromis Aureus, Culture, Michelle C. Lowery

Electronic Theses and Dissertations

Since the 1980s, non-algal aquaculture has grown to encompass 49% of all seafood production in response to a growing human population and increased seafood demand (FAO, 2022). Hurdles exist to aquaculture sustainability, including dependence on wild sourced fishmeal (FM) and the impacts wastewater discharge. It takes 4-5 tons of wild forage fish to produce one ton of dry FM (Miles and Chapman, 2006) and as aquaculture is primarily conducted in earthen ponds and public open water bodies (FAO, 2022), finfish culture can have a high impact on the surrounding environment by discharging excess nutrients. This study used algae turf scrubber …


Using Zebrafish (Danio Rerio) To Evaluate The Use Of Food Waste Based Feed In Sustainable Small-Scale Aquaculture, Caitlin May Jan 2021

Using Zebrafish (Danio Rerio) To Evaluate The Use Of Food Waste Based Feed In Sustainable Small-Scale Aquaculture, Caitlin May

Electronic Theses and Dissertations

Food waste is rich in nutrients and a valuable resource, but currently its primary method of disposal in the United States (US) is unsustainable. In 2018 the US Environmental Protection Agency (EPA) estimated that the commercial, institutional, and residential sectors of the US economy wasted 63 million metric tons of food, most of which was sent to landfills. Instead, food waste could be recycled and used to supplement or replace commercial feed in aquaculture to sustainably stimulate production of fish. Zebrafish (Danio rerio) are a well characterized animal model closely related to other fish species that are important …


Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana Jan 2020

Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana

Electronic Theses and Dissertations

Human actions such as overgrazing, the development of cities at the expense of forests, high intensity and poor agricultural management, and so forth, reduce the resources available for future generations. Because Earth has limited resources, it is important to judiciously use and manage natural resources. Human actions towards nature are the focus of my research in Africa. Increased demands for grazing, agriculture, and ecosystem services led some farmers in developing countries to use unsustainable practices, which may lead to low incomes and poor food nutrition for households. Farmer managed natural regeneration (FMNR) may be a solution to these issues. FMNR …


Broth: Enhancing Market Opportunities And Improving Sustainability Of Maine Farmed Seaweed, Zachary M. Bonelli Aug 2018

Broth: Enhancing Market Opportunities And Improving Sustainability Of Maine Farmed Seaweed, Zachary M. Bonelli

Electronic Theses and Dissertations

Seaweed is becoming popular across the world as consumers learn about the variety of seaweed-based products and their health benefits. Sugar kelp is one of Maine’s seaweed varieties that is locally grown each year. Sugar kelp and similar species contain many useful nutrients including iodine, calcium, magnesium, iron, and vitamins A, B, C, and E. Even though the health benefits of seaweed have been proven, locally-sourced seaweed has not yet become any more popular in Maine. Part one of this study identified suitable processing steps for a sugar kelp-based broth. Part two assessed how consumers’ demographics and food neophobia, as …


T Socio-Ecology Of Managed Honeybees (Apis Mellifera) In The Louisville Metro Area., Haileigh M. Arnold May 2018

T Socio-Ecology Of Managed Honeybees (Apis Mellifera) In The Louisville Metro Area., Haileigh M. Arnold

Electronic Theses and Dissertations

Humans have a long history of the practice of beekeeping to harness the power of pollination. This managed pollinator system consists of beekeepers, honeybees, and their environment. However, recent disease, pesticide use, and land use factors honeybee threaten this relationship. In the face of such concerns it is important to examine the factors that impact and can help sustain our managed pollinator systems. In this thesis, the national and Kentucky state-level policies that affect managed pollinator systems were examined and socio-ecological factors that may contribute to honeybee hive growth and losses were assessed along an urban development gradient in Louisville, …


Financial Investment Management For Forest Sustainability, Zarina Ismailova Jan 2016

Financial Investment Management For Forest Sustainability, Zarina Ismailova

Electronic Theses and Dissertations

This is paper is discussion about main problems of forest management, whether financial investment has a substantial impact on the long term perspective of forest landscape restoration and, more specifically, what strategy and what financial options are available to make the forest projects more sustainable. A few relevant questions to ask are: who are the main actors in the implementation of FLR projects; which steps have to be taken; and, which financial options would more suitable and would be feasible to implement. There are three main parts of this research to be investigated:

  1. forest issues along with their respective solutions, …


Energy In The Corn Belt: Is Maize Production Sustainable?, Matthew Bernau Jan 2013

Energy In The Corn Belt: Is Maize Production Sustainable?, Matthew Bernau

Electronic Theses and Dissertations

Technological and scientific innovation has transformed agricultural production. Corn production methods changed from a sustainable, nutrient recycling production system to one reliant on imported fossil energy inputs. Located in the Western Corn Belt, Union County, South Dakota was chosen as the study area. Changes in production methods are represented by four technological epochs: 1) The Draft Horse Epoch, 1890-1920; 2) The Tractor Epoch, 1920-1950; 3) The Fertilizer Epoch, 1950-1980; and 4) The Biotechnology and Precision Agriculture Epoch, 1980-2010. The energy budget method was used to measure the energy sustainability of corn production. The findings show that the volume of corn …
