The objectives of this thesis were: 1) to determine which factors and biological samples were associated with the estimated amount of total arsenic (As) consumed from water and food; 2) to determine which factors were associated with the concentration of total and speciated As ([As]) in urine; 3) to...

Resistance development to parasiticides has been a problem in both terrestrial and aquatic environments. A major challenge exists in early detection of resistance emergence due to the low frequency at which resistant organisms can occur initially within a population and the difficulty in detecting t...

The Atlantic Canadian aquaculture industry is dominated by Atlantic salmon production. In recent years, infectious disease, parasitic infestations, and price fluctuations from international competition have caused disruptions to the industry. Diversification of the industry away from Atlantic salmon...

There are currently four invasive tunicate species which are causing significant challenges to the aquaculture industry in Atlantic Canada: Ciona intestinalis, Styela clava, Botryllus schlosseri and Botrylloides violaceus. These tunicates foul mussel socks, aquaculture gear, boat hulls and wharves. ...

In 2005, trichomonosis emerged as a new cause of substantial mortality in United Kingdom (UK) greenfinch (Carduelis chloris) and chaffinch (Fringella coelebs) populations. Similar to the UK, in the summer and fall of 2007–2009 and 2011, mortalities due to trichomonosis occurred in the Canadian Mar...

Effective control of parasitic sea lice (including Lepeophtheirus salmonis and Caligus elongatus), is a major challenge currently facing sea cage salmon aquaculture. Emamectin benzoate (EMB; SLICE®), a macrocyclic lactone (ML), has been the drug of choice for sea lice treatment over the past decade...

Potato farming and lobster fishing are two important industries on Prince Edward Island. However for both industries to be sustainable, they must be managed responsibly. Recently, agricultural runoff has been suspected to have caused numerous fish kills in rivers throughout the island. Although a pe...

Natural products have long been recognized for their medicinal value in traditional medicine and remain an important component of modern drug discovery. Known for their immense structural diversity, natural products are secondary metabolites that often exhibit unique pharmacological properties. In t...
