I did my BSc in biology (marine concentration) at the Université du Québec à Rimouski. During these studies, I developed a real interest for all the benthic world and especially for the aquaculture. A master study on the impacts of shellfish aquaculture is a great opportunity for me to work on what I’m interested!

Ecosystem Function, EF-10: Intertidal bivalve aquaculture and biogeochemical fluxes

Lavoie2Nutrient fluxes and respiration are important ecological processes in the marine environment, particularly in coastal areas. This project explores the influence of intertidal bivalve aquaculture (Manila clams culture) on benthic respiration and nutrient fluxes. It evaluates potential factors that account for the modified nutrient fluxes and respiration due to the presence of the bivalves being farmed (i.e., their physical and biological presence and the structures used for the culture) or the ecosystem services that they provide (i.e., how they modify the environment through bio-deposition, etc).

The specific project/thesis aims project are:

1. Impact of the Manila clams culture on the biogeochemical fluxes and the benthic respiration

2. Impact of the farm structures, the nets placed to remove the predators with the fouling organisms on them

3. Determination of the sedimentation rate with the presence of the nets My project is directly related with the CHONe theme on Ecosystem Function.
