Restauration & Ökologie des Sterlets in der österreichischen Donau – das LIFE-Sterlet-Projekt 2015–2022

Österreichische Wasser- und Abfallwirtschaft, 2022
ZusammenfassungStöre sind ein wesentliches Faunenelement der Donau und stellten in der Vergangenheit durch ihre Migration ein prägendes ökologisches Verbindungsglied zwischen dem alpinen Donauraum und dem Schwarzen Meer dar. Heute sind zwei von sechs Donaustörarten bereits ausgestorben und die verbliebenen Arten sind durch Wilderei, Beifang ...

Potential Mechanisms of Dietary Potassium Diformate and Sodium Propionate Driving Intestinal Microbiota and Lipid Metabolites to Modulate Intestinal Health of <i>Trachinotus ovatus</i>. [PDF]

Aquac Nutr
This study aims to investigate the effects of potassium diformate (KDF) and sodium propionate (NaP) on gut digestive and immune functions, intestinal microbiota, and lipid metabolites of Trachinotus ovatus based on multiomics approach. Juvenile T. ovatus (initial weight: 8.65 ± 0.02 g) were subjected to a 56‐day feeding regimen.

Immunohistochemical mapping of thymic microenvironment in sterlet (Acipenser ruthenus) [PDF]

Veterinární medicína, 2020
In this study, we describe the immunohistochemical characterisation of the thymus, the main lymphoid organ, in sturgeon. The wide range cytokeratin, vimentin, S-100 protein, LCA (CD45) and CD3 were selected as the immunohistochemical markers to map the thymus in juvenile sterlet (Acipenser ruthenus).

Chemical induction of haploid gynogenesis in sterlet Acipenser ruthenus [PDF]

Czech Journal of Animal Science, 2014
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,

Preliminary results of intraspecific sterlet hybrid (Siberian sterlet × sterlet) rearing under intensive conditions

Acta Agraria Debreceniensis, 2012
Due to early maturation and a small size, sterlet (Acipenserrut-henus) is a very advantageous fish for intensive sturgeon farming with regard to caviar production. According to our previous observations, the growth potential of Siberian sterlet (A.ruthenusmarsiglii) is higher than that of the European one.
