Long-term changes of sterlet (Acipenser ruthenus) population in the Hungarian section of the Danube [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2009
Sturgeons had played an important role in the history of Hungarian fisheries, but due to over-fishing, followed by extensive river regulations and deterioration of habitats, there has been a considerable decrease in populations which are now on the verge

Correlations and Interdependencies of the Main Morphological Traits in Sterlet (Acipenser ruthenus) Fingerlings, Reared in Recirculating Aquaculture System

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The aquaculture of the sturgeons from the Danube River basin is a niche approached by more and more Romanian entrepreneurs. The sterlet (Acipenser ruthenus) is a fresh water sturgeon with some useful characteristics that recommend this species to become ...

Heavy metals Hg, Cd, and Pb in the body of sterlet (Acipenser ruthenus L.), the Lower Irtysh River

open access: yesVestnik MGTU, 2019
For assessing the possibility of using sterlet as a species-bioindicator of heavy metals' contamination in the bottom sediments, a study has been conducted on the distribution and accumulation of these pollutants in the fish body.

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 ...

Enrichment in a Fish Polyculture: Does it Affect Fish Behaviour and Development of Only One Species or Both?

open access: yesApplied Sciences, 2022
Physical enrichment of structures has been used for the last decades in aquaculture to improve fish production and welfare. Until now, this enrichment has been practiced in fish monoculture but not in fish polyculture.

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
