Abstract Invasive fish threaten ponds' ecological status and their ecosystem services, therefore obtaining a representative sample of community composition is fundamental to fishery management, research nature conservation. Estimates the size distribution, density biomass topmouth gudgeon ( Pseudorasbora parva ) model species invasive in three ponds were compared among sampling methods: electrofishing, fish‐trapping throw‐netting. The study illustrates that fish, P. , can be detected by all...
This study examined the effect of temperature on egg incubation, survival eggs during embryonic development and quality newly hatched larvae northern pike (Esox lucius L.) under laboratory conditions. Eggs similar size (diameter 2.7 ± 0.16 mm weight 6.11 0.35 mg) from five females were incubated at 3, 6, 10, 14, 18°C (groups A, B, C, D, E, respectively). The lowest fertilization (FR) hatching rates (HR) observed in group 44.6 3.2% 18.26 2.25%, respectively. highest FR HR found B (FR, 71.3...
Eutrophication and nutrient pollution is a serious problem in many fish aquaculture ponds, whose causes are often not well documented. The efficiency of using inputs for production hypereutrophic fishpond (Dehtář), was evaluated organic carbon (OC), nitrogen (N) phosphorus (P) balances measurement ecosystem metabolism rates 2015. Primary feeds were the main OC contributed 82% 13% to total input, respectively. Feeds manure major nutrients 73% 86% N P, Ecosystem respiration, accumulation water...
Biogeographical barriers formed by natural forces over billions of years have been substantially disrupted human activity, particularly in recent centuries. In response to these anthropogenic changes, global homogenization biota is observed at an ever-increasing rate, causing environmental and economic losses as well emerging health risks. Identifying factors underlying alien species richness essential for prevention future introductions subsequent spread. this study, we examined the effects...
Early life history of Clarias gariepinus from egg fertilization to full yolk sac resorption was studied at 33 temperatures within the thermal range 17.4–35.6°C. The viable temperature for embryonic development; which ontogeny is hypothetically arrested (15.4°C); larval and number effective day-degrees periods were determined. early C. found be temperature-dependent in terms onset key ontogenetic events, developmental rate, survival size larvae. length incubation period, hatching larvae...
The round goby Neogobius melanostomus (Pallas, 1814) is one of the most problematic invasive fish species in recent years Europe. It has proliferated from its native Ponto-Caspian region to several European river systems including their mouths and coastal brackish waters was also introduced became widely established Great Lakes North America. Despite reports about further invasions Odra Vistula Rivers, penetration Baltic Seas, Elbe River this only recorded near mouth close Hamburg. Here we...
Rapid expansion of round goby (Neogobius melanostomus) and western tubenose (Proterorhinus semilunaris) beyond their native ranges calls for urgent management action, particularly in localities with high introduction possibility the species. We used a comparative functional response (FR) approach to forecast invader ecological impact. compared foraging efficiency three habitat structures: sand, coarse gravel, gravel an artificial plant. Both Neogobius melanostomus Proterorhinus semilunaris...
Ploidy analyses of 116 weatherfish Misgurnus fossilis individuals revealed the sympatric occurrence triploid, intermediate aneuploid and tetraploid specimens in a 1:1:4 ratio. No diploids were detected sex ratio triploids tetraploids was 1:1, while that aneuploids skewed at 3:1 for males. An origin from mating with is hypothesized.
Effect of incubation temperature (range: 9–36 °C; interval: 3 °C) on artificially propagated weatherfish (Misgurnus fossilis) early ontogeny (during interval from egg fertilization to the finish hatching) was investigated. Both, amplitude period (evaluated in four crucial moments), total hatching duration inversely proportional and ranged 17.5 days at 9 °C 1.8 24 (expressed H50) or 137 hours °C, respectively. There were no influence rising length newly hatched larvae (TL = 4.23–4.67 mm),...
The round goby is an invasive fish in Europe and North America that threatens native species by predation competition. Its habitat preferences are similar to those of the European bullhead, which it displaces from shelters out-competes for available resources. We assessed microhabitat preferences, shelter use, activity bullhead single-species experiments simulator systems investigate their behavior a novel environment. Fish were video-recorded 28 h presence feed with water velocity ranging...
Thermal requirements of larval weatherfish Misgurnus fossilis were investigated in terms growth, survival and aerobic performance. Growth M. larvae acclimated to five temperatures (11, 15, 19, 23 27° C) measured over 25 days. In the upper temperature treatments (19, C), was stable throughout entire rearing period (>75%), whereas 11 15° C resulted severe declines (to <10%). (expressed as dry mass total length) highest at 19 23° C, but significantly decreased C. Routine metabolic rate 3 days...
The study investigated the combined effect of weaning from live feed to a commercial dry pellet at 10, 15, 20, 25 or 30 days posthatching (dph) and co-feeding for 1, 3 6 on survival growth Coregonus peled larvae. Additional groups fed only Artemia sp. nauplii (ART), Biomar LARVIVA ProWean 100 (DRY) were included. A final rate 66.4%–85.5% was observed in weaned after 20 dph. Final body weight (BW) total length (TL) significantly lower 10 15 dph, regardless duration co-feeding. Larvae reached...
