The rapid expansion of the aquaculture industry has fueled significant advances in fish health and nutrition. One such innovation has been the development of the growth-enhanced Atlantic salmon, AquAdvantage Salmon (AAS), which was approved for commercial production and consumption in the US in 2015. AquAdvantage Salmon are raised exclusively in land-based operations using highly efficient recirculating aquaculture systems (RAS) that depend on microbial communities to degrade waste and excess feed.
The general aim of this proposal is to discover new natural products with antiviral activity against the coronavirus SARS-CoV-2, which is responsible for the current COVID-19 global pandemic. Our lab has a collection of ~ 7,000 unique bacteria and fungi derived from marine sources that we will use to screen for the production of antiviral compounds. While we do not have the lab infrastructure to directly grow SARS-CoV-2, we will use distantly related human coronaviruses to complete this project.
Rapid prototyping, or 3D printing, has inspired the imagination of the general public, from simple build-it-yourself “hobby” machines using polymer-based binder material with inkjet functionality, to portable printers that can fashion components in zero gravity on the International Space Station. The functionality is user-friendly, in that printed material is dropped onto a substrate in viscous plastic form, which solidifies to take on the designed shape.
In the context of ocean sustainability of west coast of Canada, some questions that need to be considered are: what is the significance of environmental indicators related to the impact on marine aquatic species? How can changes in environment be predicted by patterns of bioindicators, for example as a result of hypoxia, affecting farmed and wild salmon? A starting point to answer these questions is the development of a centralized, common, accessible database that documents the shift in marine observation metadata collected in the area.
The proposed research investigates an opportunity of monitor, measure, and model the role of carbon sequestration and emission of carbon dioxide from agricultural soils of Atlantic Canada. Precision agricultural practices will be designed to promote sustainable agriculture in Atlantic Canada.
The goal is to help understand the effects of cold water temperatures, and the infiltration of sediment from agriculture on the survival of Atlantic salmon from egg to juvenile in PEI. Three rivers on PEI will be studied that have a range of fair to excellent Atlantic salmon populations. Total year class failure has been noted on more than one occasion over recent years and understanding the cause will be implement to help address this major population limiting factor.
Diadromous native salmonid species in coastal areas have been impacted by a multitude of factors including poor fish passage for over a century, and by an introduced salmonid, the rainbow trout. The overall goal of this study is to examine the impact of fishway improvement and anadromy, or the lack thereof, on brook trout populations. This research will provide data to inform coastal restoration efforts, particularly fish passage/fishway design, and generate new knowledge useful to the assessment environmental flows and the impacts of the introduction of non-native fish species.
The proposed research investigates an opportunity of developing renewable bio-based diesel fuel as an alternative to petroleum based fuel to lower the emission of greenhouse gases. High temperature pyrolysis of wood chips will be investigated in multi-stage pyrolysis and fluidized bed system and the quality of liquid oil will be compared for diesel substitution.
The general aim of this proposal is to discover new natural products with antibacterial activity of relevance to companion animal health. While numerous discoveries of natural products have been made, the rate of discovery of new natural products has declined in recent years. The strategy outlined in this project aims to provide a streamlined approach to the discovery of new bioactive natural products. Nautilus Biosciences is the partner organization that will benefit directly from this project.
