The Effects Of Probiotic Therapy On Stress Coping Styles Of Triploid Juvenile Farmed Chinook Salmon, Oncorhynchus Tshawytscha, Brendyn M. St. Louis
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, …
Marine Aquaculture In Maine: Understanding Diverse Perspectives And Interactions At Multiple Scales, Melissa L. Britsch
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 …
Social And Ecological Factors Affecting The Adoption Of Aquaculture, Karen Pianka
Social And Ecological Factors Affecting The Adoption Of Aquaculture, Karen Pianka
Electronic Theses and Dissertations
Commercial fishermen in Maine are increasingly dependent upon the American lobster fishery, and this reliance on a single species poses a threat to working waterfronts. Aquaculture represents a potential opportunity for commercial fishermen to diversify their income. Literature on the adoption of innovation suggests that factors such as age, education level, fishing experience, diversification, and leadership are important predictors of early adoption of innovation. However, few studies have examined whether such factors affect the adoption of aquaculture by commercial fishermen. Our marine policy research studied fishermen enrolled in two pilot shellfish and seaweed aquaculture classes held in 2013 in Harpswell …
