The Institute of Hydrobiology (IHB; www.hbu.cas.cz) at the Biology Centre of the Czech Academy of Sciences in Ceske Budejovice, Czech Republic, is looking for an expert on the behavior of predatory fish and related expertise.

The IHB is the main institution in the Czech Republic engaged in comprehensive research of freshwater man-made reservoirs and natural lakes. Limnological interactions are studied both in water bodies and their catchments. The Institute performs research on different levels of interactions from the ecosystem, community, population, organismal, through cellular to molecular levels. The investigations combine regular long-term ecological research at several reservoir and lake systems, comparative and methodical studies and different scale experiments that allow examining the phenomena at different time and space scales. The Institute applies a holistic approach from elementary chemistry to high trophic levels and social effects on water systems. Special investigations going beyond the investigations of lakes and reservoirs involve ponds, running waters and other aquatic environment.

Offered position is primarily part of the project “Biomanipulation as a tool for the improvement of reservoir water quality”, that will address following questions insufficiently understood for deep reservoirs:

(1) Is the massive reduction of fish stock of deep stratified reservoirs practically possible and sustainable?

(2) Will this treatment generate positive changes e.g. increasing of zooplankton size and density, reduction of phytoplankton closely connected with decreasing of chlorophyll‐a concentration, reduction of cyanobacteria blooms, increasing of water transparency and decreasing of total metabolism of reservoir?

(3) Can the morphologically limited littoral of deep reservoirs play the same role as in shallow lakes i.e. host different species of aquatic macrophytes which take over significant share of nutrient utilization?

(4) Will the processes in epilimnion influence the water quality in hypolimnion, from where the water is pumped for waterworks utilization? Is the biomanipulation of deep reservoirs effective with regards to the costs for water cleaning and increasing of recreational potential of reservoir?

(5) Can the biomanipulation increase ecological integrity, ecological potential and ecosystem services of deep stratified reservoirs?

Target start date is 1 January 2019. Initial appointment will be for 12 months, with an extension for up to 24 more months based on initial performance. We offer a highly competitive salary in local standards (25000-33000 CZK monthly) commensurate with the applicant’s experience and skills. Successful applicant will be encouraged to develop his/her own research agenda compatible with the overall aims of the project.


Interested applicants should email the following documents to Dr. Jiří Peterka (jiri.peterka@hbu.cas.cz) until 21th December 2018  11:59 a.m.

1) CV including description of previous experience, skills and interests in the position

2) Copies of 1-2 relevant publications

3) Copies of relevant diplomas

4) Contact for 2 academic referees


Ceske Budejovice is a medium-sized town ca. 150 km south of Prague with 100,000 inhabitants, a relaxed atmosphere, and a growing expat community at the Biology Centre and the University. Both the town and the surrounding countryside provide numerous opportunities for research and leisure activities. Living costs are low by international standards. Foreign applicants will receive support in transferring to the Czech Republic. The Institute can also help secure non-commercial accommodation in dormitories at the campus shared by the Biology Centre and the University. Czech courses are available for foreign staff to reach a basic level of proficiency in everyday situations.
