Natura Sloveniae, 2018 We present recent records of sturgeons and paddlefishes from the rivers in Danube basin in Slovenia after 2000. Strictly, only confirmed and unambiguous records (specimen, picture) were taken into account. The sterlet and the Siberian sturgeon have been

Evolutionary Applications, Volume 18, Issue 3, March 2025.ABSTRACT Translocations are carried out either unintentionally or intentionally for conservation or management reasons. In both cases, translocated populations may genetically impact natural populations via introgression. Understanding how genetic background may affect an establishment in a novel environment and the potential risks for native ...

River Research and Applications, Volume 41, Issue 2, Page 448-465, February 2025.Abstract Sturgeons are a group of iconic rheophilic fish whose populations worldwide are currently undergoing significant declines. The study investigates the impact of climate change and anthropogenic activities, particularly the Gabčíkovo barrage system, on the survival and distribution of the sterlet, the last surviving sturgeon species in the ...

Fisheries Management and Ecology, Volume 32, Issue 1, February 2025.Abstract Sterlet (Acipenser ruthenus), one of the last sturgeons in the Danube basin, is regularly stocked in national and international restoration programs, but the efficacy of stocking has not yet been evaluated. Effectiveness of stocking should involve marking and evaluating growth and survival of juveniles.

Analysis of metallothionein gene structure in sterlet (Acipenser ruthenus) during copper exposure
Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2017 Aquatic organisms present, not only simple sources of accumulated metal, but can interact with metals, altering their toxicity. Due to exposition of biosphere with metals, organisms have developed various defense mechanisms to protect themselves against ...

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the effects of increased water temperature (IWT) on fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of ...

The Research Advances in Distant Hybridization and Gynogenesis in Fish
Reviews in Aquaculture, Volume 17, Issue 1, January 2025.ABSTRACT Distant hybridization and gynogenesis are two prevalent breeding techniques for fishes. Drawing from the research achievements of our team and the existing literature, we summarize the reproductive traits and genetic features of fishes derived from distant hybridizations and gynogenesis, and we deduce the fundamental mechanisms of these two ...
