Genetic Monitoring of Brown Trout Released Into a Novel Environment: Establishment and Genetic Impact on Natural Populations

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 ...

Implications of climate‐change‐induced stressors and water management for sterlet populations in the Middle and Upper River Danube

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 ...

First review of recent records of sturgeons and paddlefishes (Acipenseriformes) in the Danube River basin in Slovenia

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

USING CRYOPRESERVED SPERM FOR CREATING STERLET BROOD STOCK

Vestnik of Astrakhan State Technical University. Series: Fishing industry, 2017
The research on the sterlet roe artificial insemination using cryopreserved sperm was carried out in the research base of the RAS Southern Scientific Centre (the Rostov region). Reproductive cells (including cryopreserved cells), larvae, sterlet fry ( Acipenser ruthenus Linnaeus, 1758) were taken as an object of research.

Effectiveness of mass marking of juvenile sterlet (Acipenser ruthenus) with alizarin red S stain on field detection

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.

Impacts of Global Warming on Quality of Male Fishes: Evidence From A Meta‐Analysis of Temperature Effects on Sperm Motility Kinematics

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 ...

Disturbances in the ploidy level in the gynogenetic sterlet Acipenser ruthenus [PDF]

Journal of Applied Genetics, 2017
Artificial mitotic gynogenesis, a chromosome set manipulation, is applied to provide the homozygous progeny with only maternal inheritance. Here, gynogenetic development was induced in the sterlet Acipenser ruthenus L. (Acipenseridae) by activation of the eggs originating from albino females with the UV-irradiated spermatozoa from wild-coloured males ...

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 ...
