AQUACULTURE AND THE BENTHIC HABITAT: BAY-SCALE VARIABILITY IN RESPONSE TO ORGANIC LOADING AND NOVEL APPROACHES TO INFORM REGULATORY MONITORING PRACTICES
(2021-08-16)Frequent assessment and revision of environmental regulatory methods is necessary to promote a sustainable approach to ecosystem management. This thesis focused on benthic monitoring practices presently utilized by the ... -
Effects of an Aquaculture Fish Farm on the Sediment Geochemistry of a Naturally Anoxic Basin
(2023-08-01)The Whycocomagh Basin, located in the Bras d’Or Lakes, Nova Scotia, is a naturally deep and anoxic basin that presently houses a Steelhead Trout (Oncorhynchus mykiss) aquaculture farm operated as an economic resource by ... -
EVALUATING ECOSYSTEM-LEVEL BENTHIC EFFECTS OF FINFISH AQUACULTURE IN COASTAL NOVA SCOTIA
(2021-08-13)Increased production of finfish aquaculture in coastal ecosystems is leading to greater concerns of the spatiotemporal effects of benthic organic enrichment. While the effects of organic enrichment have been studied ... -
Evaluating the Functional Trophic Level of the Global Aquaculture Sector
(2016-04)Previous studies have characterized the average trophic level of aquatic animals in culture at national, regional or global scales. All of these prior analyses, however, have assumed that the trophic level of an animal in ... -
EXPLORING LARVAL SETTLEMENT OF THE EASTERN OYSTER (CRASSOSTREA VIRGINICA) IN ATLANTIC CANADA
(2024-04-25)An ongoing issue for the Nova Scotia oyster aquaculture industry is the lack of reliable seed sources, which primarily relies on collecting wild seed. This thesis focuses on understanding and predicting the timing of ... -

Hybrid Landscapes: Nature, Architectural Form, and Cultural Programming for Resiliency in the Mekong Delta
(2020-08-18)The Vietnamese Mekong Delta is a region characterized by the entwined natural and human landscapes that are perpetually being redefined. From the colonial periods to postwar nation-building, homogeneous modernization ... -
LOCAL AND REGIONAL DRIVERS OF OXYGEN VARIABILITY IN COASTAL EMBAYMENTS ON THE SOUTHWEST SCOTIAN SHELF: IMPLICATIONS FOR NOVA SCOTIA ATLANTIC SALMON (SALMO SALAR) FARMING
(2022-08-30)Globally, the coastal ocean is increasingly threatened by climate change-related stressors, such as ocean warming and deoxygenation. As a result, anthropogenic activities such as sea cage aquaculture, which often occurs ... -
Morphological Variation and Genetic Differentiation in Wild and Domestic Atlantic Salmon from Southern Newfoundland
(2020-12-16)Adaptive divergence is an important force structuring wild populations and directly influencing species persistence and stability. Wild Atlantic Salmon (Salmo salar) have declined across their native range in recent ... -
Quantifying Transport of Aquaculture Particulate Wastes
(2019-04-08)Scientific understanding of aquaculture interactions with the environment is limited, especially with regard to the far-field transport and possible impacts of particulate wastes. Both modelling and field studies have ... -
The role of eco-certification in marine salmon farming
(2023-08-10)Eco-certification schemes are certifying an increasing volume of farmed seafood. These schemes promise to improve industry practices and sustainability by creating market incentives for producers to participate in ... -
Use of visual data in benthic enrichment classification
(2014-12-15)Artificial eutrophication continues to be a primary concern associated with aquaculture practices. In Canada, monitoring benthic health in response to organic enrichment is used to manage these impacts and maintain the ... -
Using eDNA to Track Microbial and Meiofaunal Communities in the Environment Surrounding Coastal Finfish Aquaculture in Nova Scotia
(2021-04-08)Finfish aquaculture has increased globally in recent years, leading to concerns about effects on the surrounding environment. Traditionally used biological environmental monitoring techniques are often time consuming and ... -
USING MACROALGAE, DISSOLVED NUTRIENT CONCENTRATIONS, AND NATURAL ABUNDANCE STABLE ISOTOPES TO TRACK SOURCES OF NITROGEN IN AQUACULTURE FARMS
(2021-12-16)Seaweed aquaculture is a growing market in the North Atlantic which has sparked the need for finding areas that can naturally support their growth. In this thesis six farms growing Saccharina latissima, or sugar kelp, were ... -
UTILIZING BIOLOGGERS TO INFER BEHAVIOUR AND PHYSIOLOGY OF COMMERCIAL ATLANTIC SALMON (SALMO SALAR)
(2024-04-15)There is a growing global market for Atlantic salmon (Salmo salar). Stakeholders have a vested interest in the future of commercial operations considering the ongoing and future impacts of ocean warming as it relates to ...
