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.

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 ...

Chemical induction of haploid gynogenesis in sterlet Acipenser ruthenus [PDF]
Chromosomal manipulations in sturgeons, particularly gynogenesis, are interesting due to the potential to change female ratio in progeny that can be useful for caviar production. The optimization of UV treatment for induction of gynogenesis is complicated due to high and variable optical density of the milt due to differential spermatozoa concentration,

The Research Advances in Distant Hybridization and Gynogenesis in Fish
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 ...

Comparison of morphological characters between wild and cultured sterlet (acipenser ruthenus l.)
Sterlet (Acipenser ruthenus L.) populations in the Danube River had experienced severe decline during the 20th century, and have become dependant on stocking measures in significant area of their distribution.

Genome Manipulation Advances in Selected Aquaculture Organisms
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 ...
