Pseudomonas fluorescens and Aeromonas hydrophila bacteria are opportunistic pathogens that occur naturally in the aquatic environment gut flora of healthy fish. Both species can pose a serious threat for fish highly sensitive to water pollution. The aim this study was determine extent which amount administered feed biomass affect distribution abundance Ps. A. recirculating aquaculture system (RAS) during farming European grayling (Thymallus thymallus L.) broodstock. A total 68 samples from...
The chromosomal characteristics, locations and variations of the C-band positive heterochromatin telomeric DNA sequences were studied in European grayling karyotype (Thymallus thymallus, Salmonidae) using conventional C-banding, endonucleases digestion banding, silver nitrate (AgNO3), chromomycin A3 4′,6-diamidino-2-phenylindole staining techniques as well fluorescence situ hybridization (FISH) primed labelling. Original data on distribution segments resistant to AluI restriction...
Human activities influence the presence of potentially pathogenic bacteria in indoor air. The aim this study was to determine effect experimental rearing European grayling and perch a recirculating aquaculture system on contamination air with Aeromonas hydrophila (PPAH) resulting health risks humans. PPAH counts, their resistance seven antibiotics, multiple antibiotic (MAR) index were determined samples water from tanks. counts highest laboratory bioaerosol where two fish species reared....
This study investigated how 2+-year-old stocked pond-reared European graylings ( Thymallus thymallus ) acclimatised to a wild environment during six months (May–October 2019) after released. We examined the quantity and composition of lipids in liver, muscles visceral adipose tissues (VAT), as well size parameters, condition factors stomach contents. Our results showed low post-stocking recapture rate (5.17%) fish 6 suggesting poor acclimation environment. During monitoring, fishes exhibited...
This study determined the contents of cadmium (Cd) in muscles, ovaries, and eggs silver female European eels. The analysis content was performed on eels caught during commercial fishing freshwater Warmia Mazury (Poland), then subjected to artificial maturation ovulation processing under controlled conditions. tissues by flameless atomic spectrometry using an electrothermal atomizer. showed statistically significant differences between (
European grayling, Thymallus thymallus (Linnaeus, 1758) (Actinopterygii: Salmoniformes: Salmonidae), represents one of the highly attractive riverine fishing species in Europe. Its populations have declined Czech Republic due to various adverse factors. Current approaches for strengthening these based on restocking with artificially reared 1+ or 2+ old individuals proven be ineffective. This study focuses possibilities supporting restoring by reintroducing two-month-old, fast-growing fry...
Squalene is an antioxidant that plays essential role in fat metabolism. The study aimed to assess the effect of squalene supplied feed on growth performance, health status, and fatty acid profiles muscle liver Siberian sturgeon, rainbow trout, Eurasian perch. experimental feeds containing 0%, 0.5%, 1.0% were prepared for each fish species. Hematological biochemical indices, histology, profiling analyzed. supplementation was safe fish, no negative influence status observed. However, changes...

Abstract This study determined the effects of stocking density and water temperature on rearing parameters survival larval blue bream under controlled conditions. Two experimental variants were conducted. In first experiment, reared at different densities 20, 40, 80, 120 indiv. dm −3 25°C. second larvae in 15, 25, 30°C a 40 individuals per 3 . The achieved highest growth rate lowest tested (20 ; 69.4 mg an average length 26.8 mm) (30°C; 80.1 28.4 mm). final during temperatures ranged from...
