We are looking for post docs to study impacts of finfish and bivalve aquaculture on the environment including impacts (enhancement as well as negative impacts) on harvested wild fish populations. We plan to use Bayesian network models and Bayesian decision network approaches to explore some of this. There are opportunities for both modelling and field work and we have three main areas of focus: eastern Canada, Mediterranean France and Tahiti. These positions are open to international applicants. The poster for the positions is copied below.

Please contact me if you are interested.

Post-Doctoral Position: Bayesian network modelling of impacts of aquaculture activities on wild fish production in Canada, France and Tahiti

First advertised: 11 July 2016

Place: Fisheries and Oceans Canada Institut Maurice-Lamontagne, Mont-Joli, Quebec, Canada

Duration: 2.5 years (finish date: March 31 2019)

Subject: Aquaculture activities have immediate impacts on the surrounding environment through eutrophication caused by nutritional inputs (i.e. addition of feed in finfish aquaculture) and redirecting natural primary production energy flows into aquaculture products (bivalve aquaculture). Thus, there is evidence that aquaculture may enhance the production of fisheries species through its activities. It is expected that enhancements to wild fish production occur over longer time scales and would be more diffuse than some of the immediate negative impacts, and thus may be more difficult to measure. We are proposing a project to study both the potential negative and positive impacts of aquaculture (finfish and shellfish) on wild fish populations using Bayesian network modelling approaches possibly supplemented by aggregated mechanistic ecosystem energy modelling approaches, to better understand the interactions between both fish and bivalve culture on surrounding wild fish and invertebrate production and their associated fisheries. Field work will also be one of the responsibilities. Study areas could include Tahiti, French Polynesia; Passamaquoddy Bay, New Brunswick, Canada, Les Isles de la Madeleine, Quebec, Canada; Malpeque Bay, Prince Edward Island, Canada; Thau Lagoon, France. Aquaculture species could include blue mussels (Mytilis spp.), Atlantic salmon (Salmo salar), orbicular batfish (Platax orbicularis), pearl oysters (Pinctada spp.), and Pacific oysters (Crassostrea gigas). Two postdoctoral positions are being offered – one to work on bivalve aquaculture and the other to work on finfish aquaculture.
Goals of the modelling are to formalize causal links between aquaculture and wild populations and explore scenarios which tradeoff various process and their associated uncertainties to provide advice on siting and magnitude of aquaculture interactions.

Collaborators: Fisheries and Oceans Canada Quebec and Maritimes regions; Institut Français de Recherche pour l'Exploitation de la Mer (Ifremer); Laboratoire Environnement Ressources Languedoc Roussillon; Université de Québec à Rimouski; Université Laval; Université de la Polynésie Française; Université de Brest

Requirements: A PhD from a recognized university, strong abilities in statistics and fitting mechanistic models and a background in ecology. Proficiency in English or French is essential.

Salary: 50,503 CAD/year.

Who can apply: the position is open internationally to qualified candidates meeting educational requirements.

Application: The position will be administrated through the Canadian National Sciences and Engineering Research Council as a “Visiting Fellowship in a Canadian Government Laboratory”. This program has certain procedures to follow and requirements to meet in order to make successful application.

Deadline: as soon as possible until filled.

Information about the region: Mont-Joli is in the Bas St Laurent/Gaspesie region of Quebec. Mont-Joli is located 30 km from Rimouski, which is a full service small city with a PhD granting university and many cultural activities. Mont-Joli (YYY) is serviced by twice daily flights to Montreal by Air Canada and other regional airlines also operate daily flights. Cost of living is relatively low in this region of Quebec and accommodation is not difficult to find. French is the daily language of communication and service in the region.
