Karyological study in backcross hybrids between the sterlet, Acipenser ruthenus, and kaluga, A. dauricus (Actinopterygii: Acipenseriformes: Acipenseridae): A. ruthenus × (A. ruthenus × A. dauricus) and A. dauricus × (A. ruthenus × A. dauricus) [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2014
Many species of sturgeons have a high ability to form viable and more or less fertile hybrids by artificial crosses (Nikolukin 1972); the interbreeding between various combinations of sturgeon species was also observed in nature or assumed from some morphological and genetic data (Soldatov 1915, Berg 1948, Vasil′ev 1979, Birstein et al.

Two Paralogues as They Like It: Conserved and Divergent Evolution of Vertebrate Gcm Genes

open access: yesEvolution &Development, Volume 28, Issue 3, September 2026.
Comparative overview of Gcm1 and Gcm2 paralogues across vertebrates. Gcm2 is conserved in pharyngeal‐derived organs across gnathostomes, whereas Gcm1 shows lineage‐specific diversification from an ancestral pharyngeal context, including secondary loss in teleosts, distinct expression in bichir gills and skin, and broader expression in mammals ...

Fluorescent in situ hybridization with rDNA probes on chromosomes of Acipenser ruthenus and Acipenser naccarii (Osteichthyes Acipenseriformes) [PDF]

open access: yes, 1999
The genes for 28S and 5S rDNA were physically mapped on the chromosomes of two sturgeon species, the sterlet (Acipenser ruthenus, 2n = 118 +/- 4) and the Adriatic sturgeon (Acipenser naccarii, 2n = 248 +/- 4) by fluorescent in situ hybridization.

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate
