Fluorescent emission profiles reveal interspecific differences in three Danube River Basin sturgeon species [PDF]

Scientific Reports
Biofluorescence is widespread among marine teleosts but has not been reported in sturgeons (Acipenseridae). This exploratory study investigates interspecific differences in fluorescent emission profiles among three Danube River Basin sturgeon species ...

Unidirectional hybridization between American paddlefish Polyodon spathula (Walbaum, 1792) and sterlet Acipenser ruthenus (Linnaeus, 1758) [PDF]

PeerJ
Interspecific hybridizations among sturgeon species are feasible and often bidirectional. The American paddlefish (Polyodon spathula) from Family Polyodontidae and sturgeon species from Family Acipenseridae were reported capable of hybridization, but ...

Multi‐Marker Mitochondrial Analysis Reveals Genetic Diversity and Phylogenetic Relationships of Black Sea Sturgeons (Acipenseridae) [PDF]

Ecology and Evolution
Sturgeons represent a critical taxon for conservation due to their complex genetic structure and vulnerability to anthropogenic pressures, including poaching, overfishing, and habitat loss. This study provides a multi‐level mitochondrial characterization

Immunomodulatory peptides from sturgeon cartilage: Isolation, identification, molecular docking and effects on RAW264.7 cells [PDF]

Food Chemistry: X
Sturgeons (Acipenseridae), ancient fish known for their caviar, produce underutilized by-products like protein-rich cartilage, which is a source of high-quality bioactive peptides. This study investigates immunomodulatory peptides from sturgeon cartilage

Research Tools to Investigate Movements, Migrations, and Life History of Sturgeons (Acipenseridae), with an Emphasis on Marine-Oriented Populations [PDF]

PLoS ONE, 2013
Worldwide, sturgeons (Acipenseridae) are among the most endangered fishes due to habitat degradation, overfishing, and inherent life history characteristics (long life span, late maturation, and infrequent spawning).

Cryoprotectant-specific alterations in the proteome of Siberian sturgeon spermatozoa induced by cryopreservation [PDF]

Scientific Reports
Cryopreservation is crucial for conserving genetic diversity in endangered species including the critically endangered group of sturgeons (Acipenseridae), but it can compromise sperm quality and protein profiles.
