In the EMFAF research project IQ-Wels-MV for the innovative breeding adaptation of the African catfish to recirculating aquaculture and the genetically based trait enrichment of positive performance characteristics, we are offering three positions for research and further qualification. Position #1 (2025-23) is strongly practice-oriented and position #3 (2025-25) develops molecular genetic tools to promote fish health. In cooperation with the largest catfish farm in Mecklenburg-Vorpommern (production approx. 400 tons/year), the technical requirements for setting up a pedigree-based breeding program are being created and large numbers of fish are being phenotyped manually. The here advertised position #2 (2025-24) involves developing statistical genetic approaches for pr
