Accumulation and depuration of geosmin and 2-methylisoborneol in Japanese seabass (Lateolabrax japonicus) fed diets containing different dietary protein and lipid levels in a recirculating aquaculture system
(Master thesis, 2021)Muddy flavour caused by microbially synthesized geosmin and 2-methylisoborneol (2-MIB) represents a quality challenge for production of fish in recirculating aquaculture systems (RAS). The current study was conducted to ... -
Accuracy of genomic prediction using group recordings
(Master thesis, 2022)Group records are the alternative solutions for traits that are affected by group interaction and are difficult or costly to measure on individuals. We aimed to investigate how group size, group composition, and validation ... -
Answering the Call : Motivation and Experiences of Leaders in the Global Regenerative Forestation Movement
(Master thesis, 2020)Forestation, the planting and cultivation of trees, is an important strategy utilized by community groups, farmers, NGOs, and governments, to counteract catastrophic climate change. Regenerative forestation is an ecological ... -
Apparent Digestibility of key feed ingredients by largemouth bass (Micropterus salmoides)
(Master thesis, 2021)The aim of this project was to determine apparent digestibility coefficients (ADC) of macronutrients, amino acids (AA), phosphorus (P) and energy (EN) in protein-rich ingredients in extruded diets for largemouth bass ... -
Characterization of Functional Physical Properties of The Dry Pet Food Manufactured with Animal, Plant, and Microalgae Ingredients
(Master thesis, 2021)The aim of the thesis is to gain better understanding on the effects of defatted microalgae biomass (Desmodesmus sp.), vital wheat gluten and potato protein on physical qualities of extruded dry pet food. Two experiments ... -
Creating a typology of U.S. organic grain farmers using reduced tillage
(Master thesis, 2020)Despite an increasing number of studies demonstrating the feasibility and value of integrating reduced tillage practices into organic cropping systems, adoption of these practices has been slow, with tillage and cultivation ... -
Cultivating human beings : natural farming in South Korea
(Master thesis, 2019)Although having achieved an unprecedented rise in food production, the ecological, social and health impacts of industrial agriculture have led numerous scholars and activists to question its desirability. Regarded as a ... -
A descriptive study of the physical quality of commercial broiler pellets across the world
(Master thesis, 2021)This thesis work intends to give a general insight into commercial broiler pellets' physical quality and discuss the differences from a scientific point of view. The samples were delivered to the Norwegian University of ... -
Developing a soft systems methodology for comparing the sustainability performances of ecologically active concrete to those of the traditionally used stone as scour protection material
(Master thesis, 2020)Sustainability is one of the ‘hottest’ topics of our times: governments, scientists and public opinion have all been actively involved in the conversation for decades now, and, as a consequence, also companies are experiencing ... -
Effect of dietary protein and lipid sources on technical quality of pellets for Atlantic salmon
(Master thesis, 2022)The purpose of the research was to examine technical quality of pellets added protein (P) and oil (O) sources of vegetable (V) or marine (M) origin. Four different diets for Atlantic salmon smolts were produced with 1) ... -
Effect of using insects as a dogfood ingredient: A perspective on technology and nutrition on focus to Lumbriculus variegatus, Hermetia illucens and Tenebrio molitor- A literature review
(Master thesis, 2021)The use of insect as food and feed has been in existence for a very long time as it was used as an alternative protein source for food and feed production. The current food crises has caused researchers to find ways of ... -
Effects of day and night temperature and lighting conditions on growth, nutritional status and tipburn of lettuce (Lactuca Sativa L.`Frillice´) cultivated in controlled environment
(Master thesis, 2022)Growth chamber experiments were conducted with Lactuca sativa crisphead lettuce:`Frillice´ growing in nutrient film technique (NFT). The main objective was to study energy-efficient cultivation strategies without reductions ... -
Evaluation of the use of fractional abundance of stable carbon and nitrogen isotopes and indigestible inert marker in diets and faeces to calculate apparent digestibility of carbon and nitrogen
(Master thesis, 2018)The study carried out to test the feasibility of calculating apparent digestibilities (AD) of carbon and nitrogen with diets in fishmeal (FM), soybean meal (SBM), and rapeseed meal (RSM) as the main sources of protein by ... -
Farm-based education for food system transformation
(Master thesis, 2022)Food systems education is being studied as a “vital strategy” in transforming the current food system paradigm away from globalization and industrialization and towards a system which enables community-level food sovereignty, ... -
Fillet quality of Atlantic salmon (Salmo salar) as affected by dietary and environmental treatments
(Master thesis, 2020)Fillet quality of Atlantic salmon (Salmo salar L) is crucial for both salmon producers and consumers. There are endogenous and exogenous factors that affect fillet quality. This thesis mainly focuses on exogenous factors: ... -
