The work is carried out as part of a multidisciplinary, federally funded, project, HaffStör, which is assessing improved methods of production of fish for recovery measures and the assessment of their population development with a focus on Baltic sturgeons in the Lower Oder and Szczecin Lagoon area. The subproject aims at the identification of means to improve the rearing practice to render fish fit for survival after release through the comparison of the effectiveness of near natural rearing with state of the art RAS rearing, identifying the drivers for fitness and the resulting effects on a population level.

Your tasks

  • To supervise rearing of early life stages of sturgeons under different rearing conditions in commercial settings
  • Assess effects of environmental impacts upon fitness running behavioral and physiological studies
  • Conduct tagging experiments
  • Implement a monitoring program to assess the impact of the releases and to help discriminate the impact in relation to the origin of the fish
  • Collaborate in the execution of the monitoring program
  • Analyse the impact of rearing methods applied upon the survival and fitness of the fish at different ages
  • Close collaboration with other working groups in the project
  • Dissemination of research results (papers, conference presentations)

Your profile

  • Holding a PhD or a master degree in biology, fisheries sciences, or a related field with focus on fish biology or aquatic ecology, or equivalent education is obligatory.
  • Practical experiences with fish rearing, field work and experimentation is required,
  • Experience in monitoring of fish populations would be advantageous
