High-resolution 3D X-ray microscope Available form 02/2022
Visualization of complex internal structures of biological objects without the need for their disintegration by fixation and tissue section is one of the challenges of modern biology. To overcome this limitation, we will soon operate the High-resolution 3D X-ray microscope. A series of hundreds of X-rays of a rotating object enables the subsequent 3D reconstruction of objects and their internal structures with a resolution of fewer than five μm. The device can be used to scan various objects from plants, stones, composite materials, building materials, and even live animals. The combination of natural contrast properties of biological structures with specific contrast agents and antibodies provides an infinite potential for implementing this tool in research carried out not only at the Faculty of Science. Furthermore, compact layout, absolute safety, and simple operation allow independent work of doctoral students.

Data file for a study examining various feeding strategies for juvenile pikeperch (Sander lucioperca) in a Recirculating Aquaculture System (RAS) over a period of 112 days. It compared five different feeding intervals (2 hours, 4 hours, 6 hours, 8 hours, and 12 hours) using an automatic feeder Imetronic® (Pessac, France). The results showed that shorter feeding intervals led to higher growth heterogeneity and slightly increased fin damage. However, all tested feeding frequencies provided sufficient nutrients for proper pikeperch growth and welfare. The 8-hour feeding interval was identified as optimal, supporting better conditions for fish (Fulton's coefficient), specific growth rate, survival rate, lower fin damage compared to other tested frequencies, and optimal levels of biochemical parameters in blood plasma.
The data of a study monitoring pollution in the Danube River were collected using an innovative approach that combined passive sample collection with chemical and bioanalytical analyses within the framework of the JDS4 survey. The study focused on the use of two types of passive samplers - silicone disks for hydrophobic compounds and AttractSPETM HLB disks for hydrophilic compounds. These passive samplers were deployed at nine locations for approximately 100 days. Pollution by over 400 compounds, including industrial substances, pharmaceuticals and personal care products, and pesticides was recorded. The compounds and in vitro biological activities that may pose a risk for aquatic ecosystem were identified. The novel approach with long-term passive sampling provides a representative overview of pollution in the Danube River and can be utilized for future water quality monitoring.
Other open datasets can also be found under our community on the Zenodo open repository. Details of open science at the faculty are available here.

Project was focused on collection of tissues samples of wels catfish broodstock of strains established at the Genetic Fisheries Centre of FFPW USB and characterization of genetic variance within and between strains/families and for parentage assessment in families of their progeny using microsatellite genotyping and NGS. Following selection and qualitative assessment of reproductive performance, factorial mating of 6 females and 6 males per strain was used to establish full-sib and half-sib families. Following egg incubation and hatching, the fry was air freighted to Estonia for comparative evaluation of performance of the strains and families and to estimate heritability of commercially important traits.

Streams and rivers metabolize dissolved organic matter (DOM). Although most DOM compounds originate from natural sources, recreational use of rivers increasingly introduces chemically distinct anthropogenic DOM. The aim of this study was firstly to investigate anthropogenic effect on the increase of DOM in Traisen River in Austria during music festival, and secondly to examine fluorescence spectroscopy for monitoring DOM. Sunscreens and especially their component Phenylbenzimidazole sulfonic acid (PBSA) was found as the main source of anthropogenic pollution. This was confirmed not only by the fluorescence method but also by liquid chromatography coupled with mass spectrometry analysis of water samples in Laboratory of Environmental Chemistry and Biochemistry.

European perch, Perca fluviatilis, is a highly promising candidate for freshwater aquaculture diversification. It has great potential to deliver products of sensory quality and nutritional value according to the market demands in the EU. However, European perch production is often hampered by high sensitivity to stress under captive conditions which has a negative impact on reducing immune resistance and at the same time increasing sensitivity to diseases and pathogens. For the successful prevention of diseases, detailed information on the molecular mechanisms of immune responses among geographically distinct European perch populations against different pathogenic stimuli is requested. To overcome this obstacle, we established in vitro model of inflammation, using the stimulation of head kidney leukocytes with lipopolysaccharide (LPS), the major component of the outer membrane of Gram-negative bacteria. To this end, head kidney leukocytes (HKL) from four different European perch populations (France I and II, Denmark, Hungary) were isolated using density-gradient centrifugation and stimulated with LPS (100 µg/ml) for one hour. Following the incubation, the respiratory burst was measured using the dihydrorhodamine 123.

One of the key responses of cells on collagen-based materials is the mechanism of their adhesion on the material surface and their locomotion and proliferation on it. Therefore, the objective of this project is to evaluate the adhesion, spreading and locomotion of cells on collagen coming from different species and extracted by different methods. To extract information about cell structure and dynamics we had to develop respective software for which we developed new statistical methods for evaluation of physical parameters. We are, as first in the world, able to determine spectra of individual organelles, local diffusion, local directed flow inside the living mammalian cell and many other parameters.

Precision fish farming is an emerging concept in aquaculture research and industry, which combines new technologies and data processing methods to enable data-based decision making in fish farming. The concept is based on the automated monitoring of fish, infrastructure and the environment, ideally by contactless methods. The identification of individual fish of the same species within the cultivated group is critical for individualized treatment, biomass estimation and fish state determination. The standard way of fish identification is invasive fih tagging. The project test the posibilities of long-term fish identifiaction based on the pictures of eye pattern. We sucessfully showed that the eye pattern can be used for the identification of individual fish and can be a non-ivansive substitute to the invasive fish tagging.

The aim of the project was to examine the application of artificially produced rotifers of the species Brachionus plicatilis as the first exogenous nutrition in intensively reared pikeperch larvae (Sander lucioperca). The study of the project examined a probiotic based on Pediococcus acidilactici lactic acid bacteria in Bactocell Aqua 100 preparation. This product was tested in the form of incorporated bacteria into the body of the rotifers or enriched water with bacteria that was used for larval culture. In second study of the project, the effect of enriching produced rotifers with unsaturated fatty acids (PUFA - EPA and DHA) was tested using artificially cultured Chlorela algae or additives like Selco, Spresso preparation from INVE company from Belgium. The aim of both studies was to increase the survival rate and physiological resistance of cultured larvae to produce high-quality juveniles for further industrial farming.
