Over the past decade, four exotic tunicates (Styela clava, Ciona intestinalis, Botrylloides violaceus and Botryllus schlosseri) have been reported in the Brudenell estuary in Prince Edward Island (PEI), Canada. Styela clava was the first exotic tunicate to arrive in 1997, rapidly establishing, sprea...

With the increasing spread of invasive marine species and their detrimental effects on aquaculture operations globally, mitigation strategies need to be optimized to mitigate economic impacts. The efficacy of a potassium monopersulphonate triple salt based disinfectant used in the aquaculture indust...

Mussel (Mytilus edulis) culture in Atlantic Canada utilizes wild seed harvested from spat collection sites. The economics associated with wild-caught seed have proven to be more favourable than with hatchery-produced seed. This is not, however, the case in all areas. In Washington state, seed used f...

Triploid shellfish are sterile and retain product quality during, and after the spawning period. Field evaluations of diploid and triploid mussels demonstrated that triploids had a greater growth rate than diploids. The growth difference was evident in the first growing year after deployment in a hi...

The induction of triploidy in Mytilus edulis, using 6-dimethylaminopurine (6-DMAP), was investigated as a potential method of providing high quality sterile product in Prince Edward Island (PEI), Canada. Initial results indicated induction by blocking the second polar body would require a treatment ...

In 1999, examination of soft-shell clam (Mya arenaria) mortalities at an experimental lease on Prince Edward Island (PEI) revealed a 95% prevalence of advanced haemic neoplasia (leukaemia). Low prevalences of this condition had been documented previously in soft-shell clams from Nova Scotia and the ...

Spatial growth variation of experimentally cultured blue mussels Mytilus edulis in Tracadie Bay, Prince Edward Island, Canada, was consistent in both years of a 2 yr study. The spatial pattern displayed reduced tissue growth along a gradient of decreasing tidal exchange from the inlet mouth to the i...
