The main task of the DBU-funded CrustaWohl project is to identify practice-relevant housing conditions (e.g. water and environmental parameters, housing densities, molting events) and handling (e.g. size sorting, harvesting, cleaning work) for shrimp farming (Litopenaeus vannamei) in Germany with regard to the effects on chronic To examine stress and animal health based on behavioral, water-chemical and physiological parameters and to combine them into an application-relevant evaluation system (animal welfare index) in practice. The immediate goal is to prevent suboptimal housing conditions, chronic stress reactions, averse behavior, growth deficits and possible injuries (especially in skinned animals),



  • Carrying out husbandry experiments with the species Litopenaeus vannamei in experimental and commercial breeding facilities
  • Taking samples from shrimp and housing systems
  • Recording of animal behavior
  • Analysis/determination of behavioral, water-chemical and physiological parameters

  • Knowledge of the operation of aquaculture recirculation systems, the implementation of animal experiments and sampling
  • Knowledge of the biology and physiology of crustaceans
  • Molecular biological laboratory knowledge is mandatory
