The laboratory focused on research in fields:

- biology and breeding of crayfish
- reproduction of river fish species
- applied hydrobiology
- biological invasions
- laboratory deals with the research program of centre CENAKVA: WP4 Development and innovation of continuous water quality monitoring system using fish and crayfish as bioindicators and innovative procedures within management of water-supply reservoirs

 


Research of biology and breeding of crayfish
The field work includes monitoring of native and non-native crayfish species within the Czech Republic territory. The monitoring forms a part of projects funded by the Ministry of Education, Youth and Sport of the Czech Republic and also by individual ordering parties (administrations of national parks and protected nature reserves, environmental departments).
   
Captured noble crayfish in freshly fetched trap The diversity of benthic organisms in the streams Non-native highly invasive fish species (bullhead, pumpkinseed, round goby) caught during electro electrofishing on the river Elbe, during which was also caught convict cichlid probably released by aquarists Individuals of invasive signal crayfish captured from the locality with the occurrence of native noble crayfish Locality with occurrence of native noble crayfish and invasive alien bullhead Members of the Laboratory of Freshwater Ecosystems during field sampling of the fish community on the river Elbe Conjoined twins of marbled crayfish (second and third stage of postembryonic development) Brook lamprey, common minnow, river trout caught during biomonitoring in Obecnický brook From the locality populated by alien parthenogenetically reproducing marbled crayfish
   
Genetic diversity of crayfish
With the respect to long-term crayfish monitoring in our country, we are concerned with genetic diversity of particular populations of noble crayfish (Astacus astacus) using microsatellite markers. These markers can reveal a lot about the origin of particular individuals and whole populations as well. Whether they were established with specimens from one source (population) or the original stock was a mixture of different specimens from several sources. Another important message coming from this research is the effect of limited original stock on genetic diversity of later progeny.
One of our other topics is phylogenetic study of narrow-claw crayfish (Astacus leptodactylus) species complex. We evaluate the relationships among populations within the area of species distribution as well as among different morphotypes using set of mitochondrial and nuclear markers. The results can clarify history of recent species distribution.

We study ethology, reproduction biology, adaptability and tolerance towards various factors of environment and intra- as well as interspecific interactions of native and non-native crayfish species.

Culture of crayfish
A research of various semi-intensive and intensive methods of crayfish hatching and their rearing is made. We monitor impact of external conditions on the growth and survival of crayfish. We perform experimental stocking of crayfish into suitable natural localities in selected areas of interest with the purpose of establishing new populations. The stocking takes place always in cooperation with the local nature protection authorities.

Development and innovation of continuous water quality monitoring system using fish and crayfish as bioindicators
We perform development of water quality monitoring system using bioindicators - fish and crayfish. System combines the activity of crayfish heart scanned by special sensor with the analyses of crayfish movements recorded by video camera.

Reproduction of river fish species
The research of river fish species reproduction is made in cooperation with other laboratories, especially with Laboratory of intensive aquaculture. Our laboratory is focused especially on alternative (nature-friendly) methods of spawning and nutrition of fish riverine species, currently mainly barbel (Barbus barbus) and vimba (Vimba vimba).

Electro-fishing during biomonitoring of a community of aquatic organisms of a stream Recording of quantitative traits of caught fish by students Stone crayfish from heavily organically polluted by human activity (teddy bear) Electrofishing during monitoring of fish population on river Ploučnice (Elbe’s river tributary Electrofishing during monitoring of fish population on river Elbe Picking up of a trap at a site with a potential occurrence of non-native crayfish species Collecting of samples during diving Public awareness Rescue transfer of noble crayfish and clam individuals from a drained pond
  
Applied hydrobiology
We engage in monitoring of communities of invertebrates in both stagnant and flowing waters, where a very important part is also the assessment of impact of various types of (not only) fish farming especially on these communities.
 
Preparation of an experiment on a system simulating water flow during international cooperation Schematic drawing of a part of a system for determining the oxygen consumption of aquatic organisms (respirometry) Daniovision (Noldus) – system for detection of smaller aquatic organisms locomotion Software evaluation (Noldus Ethovision) of the crayfish trajectory from a video recording taken during the experiment / X-maze used to study the orientation of aquatic organisms in space and their response to stimuli
  
Biological invasionsWe are interested in various aspects of biological invasions among the already known, but also newly-threatening alien species in freshwater ecosystems (direct interactions, competition for food and shelter, changes of these relationships depending on biotic and abiotic factors, etc.). Tolerance and adaptability of both native and non-native species to the factors such as winter and summer temperature extremes or conditions of severe droughts are evaluated.  

 

Books, DVD, methodologies

The book Biology and Culture of Crayfish is intended not only to the professional public, and to the educational activites. We hope it will be also close to laics who are interested in the biology, culture a active protection of crayfish.
This comprehensive book by eight authors from three Czech institutions, which can be considered the centres of astacological research in the Czech Republic, summarizes the up-to-date knowledge about freshwater crayfish, their taxonomy, evolution and biogeography, current distribution of European species, crayfish genetic variation, anatomy, biology, breeding, diseases, and conservation. The book contains the following chapters: Systematics and Distribution of Crayfish; Evolution and Historical Biogeography of Crayfish; Crayfish Genetics; Crayfish Species in Europe; Morphology and Anatomy of Crayfish; Reproduction and Life Cycle; Ecology of Crayfish; Diseases, Parasites and Commensals of Crayfish; Production and Culture of Crayfish; Monitoring of Crayfish Occurrence; Crayfish Conservation. The annex of the book contains the full list of Czech and Slovak astacological literature.
