We describe 4 years of an experimental rotation in ecosystem health offered to senior veterinary students in Canada. Faculty from the 4 Canadian veterinary colleges collaborated in offering the rotation once annually at 1 of the colleges. The 1st rotation was held in Guelph in 1993, followed in succ...

Anecdotal reports from mussel growers suggest that increased stocking density decreases the settlement and growth of the fouling organisms Styela clava (clubbed tunicate) and Ciona intestinalis (vase tunicate). To evaluate this hypothesis, 15 mussel socks of low (90 mussels per 30 cm), medium (250 m...

The epidemiology and importance of coagulase negative staphylococcal (CNS) mastitis in Prince Edward Island had not been documented. To investigate this, a cohort of 84 cows at seven farms were quarter sampled eight times over a lactation, commencing with samples taken prior to drying off in the pre...

In 2004, an exotic tunicate, Ciona intestinalis, was detected in Montague River, Prince Edward Island. Since it was first detected, this exotic species has become an invasive nuisance species creating production problems in bivalve aquaculture industries including handling difficulties and resource ...

The first confirmed report of the invasive solitary ascidian Styela clava (clubbed tunicate) in the blue mussel (Mytilus edulis)
production area of March Water in Malpeque Bay, Prince Edward Island (PEI), occurred in September of 2002. Mussel farms in
eastern PEI waters have been challenge...

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. ...

Aquatic invasive species decrease yields and increase costs in aquaculture operations worldwide. Anecdotal evidence from Prince Edward Island (PEI, Canada) estuaries suggested that recruitment of the non-indigenous solitary tunicate Ciona intestinalis may be lower on aquaculture gear where colonial ...

A variety of human enteropathogens, including viruses, bacteria, and parasites, have been shown to bioaccumulate in suspension-feeding bivalve shellfish. Cryptosporidium parvum is a zoonotic protozoan parasite that has been detected in many shellfish species within both fecally contaminated and clea...

A mathematical model was used to describe the population of the aquatic invasive species, Ciona intestinalis in the presence of cultured mussel production. A differential equation model was developed to represent the key life stages: egg, larva, recruit, juvenile and adult. Stage transition rates we...

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...

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.

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,...

Cysts of the protozoan parasite Giardia have been detected in many bivalve shellfish species worldwide. The detection of zoonotic Giardia duodenalis assemblages A and B is of public health concern, yet there is limited data available demonstrating the bioaccumulation and elimination of Giardia cysts...

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 Island. The aim of thi...

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...
