The zoonotic protozoan parasites Cryptosporidium parvum, and Giardia duodenalis can colonize the gastrointestinal tracts of many farmed, domestic and wild animals, and are capable of causing disease in humans. Due to their high prevalence in dairy and beef cattle, farms are considered to be potentia...

A letter to the editor is presented discussing polychaete composition in blue mussel fouling communities in relation to mussel stocking density and seasonality of mussel deployment and sampling.

Blue mussel Mytilus edulis aquaculture lines and associated gear provide habitat for sessile and mobile epifaunal fouling organisms. Due to food limitations and substrate space, these species are likely to interact among themselves and with mussels. In some areas of Prince Edward Island and elsewher...

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. ...

The aim of this study is to investigate the effects of the pesticides/polycyclic aromatic hydrocarbon mixture on aryl hydrocarbon receptor (AhR), p53 and ubiquitin mRNA level in haemocytes of Mya arenaria exposed to a mixture of chlorothalonil, mancozeb and benzo[a]pyrene (BaP) for 48 and 72 h. AhR,...

Invasive tunicates are creating costly fouling problems to the mussel aquaculture industry in many regions including Prince Edward Island, Canada. These invasive tunicates are also posing a threat to the ecosystem integrity of native species. There are currently four invasive tunicate species presen...

The recent detection of the invasive colonial tunicate Diplosoma listerianum in Havre- Aubert, Magdalen Islands (Quebec, Canada) in 2008, prompted the development of a molecular assay as a method to detect and monitor for the potential invasion of this species in Prince Edward ...

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...
