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.

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 ...

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 ...

Genome Manipulation Advances in Selected Aquaculture Organisms
Reviews in Aquaculture, Volume 17, Issue 1, January 2025.ABSTRACT With the rising global demand for seafood and the challenges posed by overfishing and climate change, the aquaculture sector has become increasingly important in providing high‐quality protein for human consumption. Although traditional selection breeding programs have made great strides in genetic improvement of aquaculture species over the ...
