PhD Scholarship in Fish Population Genetics at DTU Aqua, Denmark

PhD Scholarship in Population Genetics is available at the National Institute of Aquatic Resources (DTU Aqua) with starting date 1st November 2013.

The project will primarily be carried out in the Section for Marine Living Resources’ Population Genetics group in Silkeborg, Denmark. The PhD project is a part of a European Union joint research project assessing genetic effects of aquaculture on wild fish populations. The project is coordinated by DTU Aqua. It started November 2012 and finishes October 2016. The PhD project will have an independent profile and will be carried out in collaboration with international research partners. The successful applicant will be expected to take part in experimental work during shorter stays in Norway.

Project description
Knowledge of local adaptation and the potential for adaptation in natural populations is becoming increasingly relevant due to anthropogenic changes to the environment. Humans have cultured and released fish into wild populations for hundreds of years. However, it was not until the development of the aquaculture industry, together with increase in numbers of escapees into wild populations that genetic interactions between domesticated and wild conspecifics started to become a major global concern. The project addresses local adaptation in brown trout, Salmo trutta, and will investigate how interbreeding between individuals of wild and hatchery origin affects life history and fitness in wild populations. Common-garden experiments will be applied to identify phenotypic differences related to fitness (e.g. growth, age-at-reproduction and reproductive tactics) in trout of wild, hatchery and admixed wild/hatchery background. The project will take advantage of the fact that interbreeding between wild and farmed fish provides a unique opportunity to study functional adaptations from a general evolutionary perspective, and the project is planned to have a strong evolutionary ecology profile.
