The Department of Aquaculture of Szent István University is the only higher education department in Hungary dedicated entirely to education and research in aquaculture. The team of the department currently consists of 32 persons, including 1 professor emeritus, 9 people holding a PhD degree, 13 research and teaching associates, 2 administrators and 7 PhD students. The department is relatively new, it was formed by the aquaculture group of the former Institute of Animal Husbandry in 2000.
The mission of the Department is to represent and foster the activities of the fisheries and aquaculture sector in Hungary. This activity includes information transfer from basic knowledge through pond fish farming technologies to the most state-of-the-art molecular methods to various stakeholders including students of graduate and post-graduate training, scientists, professionals and anyone interested.

Main lines of research
Scienti”c research of the department is mostly applied research and technological development conducted in several main directions, including:
• Biology of reproduction and gametes as well as induced spawning of various fish species,
• Aquatic toxicology,
• Conservation of aquatic genetic resources,
• Stress research in fish,
• Pond and intensive aquaculture,
• Molecular biology.
The various research directions are interlinked in the research projects of the department. Thus, gamete research is generally conducted within the frames of induced spawning technology development as well as species conservation work.
* Gamete research is one of the principal research directions of the department. The current topics of gamete research in Gödöllő include the following:
* Induced spawning of the European eel (Anguilla anguilla),
* Cryopreservation of fish sperm including its application to the practice in collaboration with the Angling Club of Tolmin in Slovenia,
* Development of induced spawning technologies for rare or endangered fish species, such as Carassius carassius, Misgurnus fossilis, Umbra krameri,
* Sexual maturation of the Asian sea bass or barramundi (Lates calcarifer),
* Oocyte transplantation in fish.

The department is equipped with a state-of-the-art zebrafish holding facility consisting currently of 6 racks and one central water treatment unit, a molecular biology laboratory, a histology laboratory, a microscope laboratory housing a CASA system and a general laboratory with equipment and apparel for research on cryopreservation. Most of the cryopreservation work is typically conducted in the field in collaboration with various aquaculture farms and organizations.
