As a dedicated PhD student at the Faculty of Fisheries and Water Protection in Vodnany since September 2021, I specialize in modern methods of intensive breeding, reproduction, and biology of fish 🐟. Since October 2020, I have also served as a Biological Specialist, collaborating on scientific research projects, including NAZV, OP Fisheries, Eureka, Interreg, and H2020 πŸŒπŸ”¬. Previously, I worked at the Biological Center of the Academy of Sciences of the Czech Republic from May 2016 to May 2020 as a Laboratory Technician, where I processed biological material and introduced new lab methods such as radiotracking πŸŒ³πŸ”¬.

Research project

From February 2024 to January 2025, Her served as the responsible researcher for a project funded by the Grant Agency of the University of South Bohemia in ČeskΓ© BudΔ›jovice (GAJU). The project, 032/2023/T, focused on innovative methods for acquiring and utilizing separated sludge waste from intensive aquaculture, aiming for sustainable nutrient use in agriculture. Previously, from February 2022 to January 2023, I led another GAJU-supported project, 028/2022/T, which optimized the application of pelleted feeds with higher vitamin C content in the intensive aquaculture of pike perch (Sander lucioperca). πŸŸπŸŒ±πŸ’§πŸ“Š

Research focus

Tomas Penka’s research focuses on optimizing aquaculture practices, particularly for species like pikeperch and northern pike. His studies investigate various aspects, including the effects of bicultural stocking, live feed enrichments, and the use of lactic acid bacteria to enhance fish growth, health, and microbiome diversity. Additionally, he explores the impacts of different weaning times, light regimes, stocking densities, and dietary supplements on fish development and survival. Penka’s work aims to improve sustainable aquaculture systems and fish welfare through innovative techniques and detailed biochemical and genetic analyses. πŸŸπŸ”¬πŸŒΏπŸ“Š
