Research
The water chemistry that salmonid embryos are exposed to within the boundary layer can often be different from the free-flowing water above the redds (nests). These differences may have an unexpected detrimental effect on the embryos and little is known on how the embryos affect this microenvironment. Part of my research focuses on the differences in water chemistry between free-flowing water and the water within redds of salmonids. This field research will focus on several parameters which include oxygen, pH and ammonia levels throughout embryo development. I will be focusing on redds of the fall spawning Brook Trout and the spring spawning Rainbow Trout.
In addition to the field research I will be determining the effects of development on the water chemistry within the boundary layer of rainbow trout embryos. This will help us determine to what extent the embryo affects its microenvironment. After determining the most relevant stage of development I aim to test the effects of flow on the water chemistry of the embryo's boundary layer. In addition I will also to test the effects of crowding on the boundary layer and whether positioning of the embryos within the group plays a role in the water chemistry that they are exposed to. Both of these stresses (flow rate and crowding) may be observed in the natural setting and therefore are important to understand for conservational efforts and hatchery management.
