Abstract:
Pikeperch (Sander lucioperca) has become an important species for the diversification of aquaculture as well as for restocking purposes. In this project, conducted in collaboration with the Kaiserzander hatchery in Niederlangen, Germany, the influence of sorting processes on the early skeletal development of pikeperch larvae will be investigated. The aim of the project is to examine the mechanical stress caused by size sorting and its impact on spinal deformities in the larvae. Morphometric parameters will be measured, and skeletal deformities documented. Additionally, clearing and double staining techniques will be used to visualize internal skeletal changes. Furthermore, feed and fatty acid analyses will be conducted to evaluate potential alternative influences on bone development. The combination of morphometric, morphological, and nutritional analyses aims to provide valuable insights into the effects of mechanical stressors on the skeletal development of pikeperch. This research will contribute to optimizing rearing practices in pikeperch aquaculture and aims to improve larval quality and animal welfare.
