Recent advances in sturgeon nutrition. [PDF]

open access: yes, 2017
Sturgeons are fish species of biological and economical importance, and most of them are endangered, vulnerable or rare because of their large size, late sexual maturity, long period between spawning, and longevity.

Bony fish genomes: Status and gaps

open access: yesJournal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Nitrogenous compounds and oxygen concentration as the key density dependent factors to optimize growth of beluga, Huso huso (Actinopterygii: Acipenseriformes: Acipenseridae), in circular fiberglass tanks [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2011
Background. Beluga, Huso huso, known also as the great sturgeon, is a valuable fish in terms of meat and caviar production. It has been implicated that intensive fish culture is a major culprit for deterioration of water quality through metabolic ...

Pharmacokinetics, Optimal Dosages, and Withdrawal Time of Florfenicol in Cobia (Rachycentron canadum) After Oral Administration via Medicated Feed

open access: yesJournal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Antimicrobial drugs are commonly used for the treatment of bacterial diseases in cobia (Rachycentron canadum), but information regarding the rationale of their therapeutic use, such as pharmacokinetics (PK), optimal dosages, and withdrawal time (WDT) in this species is very rare.

A comparison of methods for determining ploidy in white sturgeon (Acipenser transmontanus) [PDF]

open access: yes, 2019
Release of sturgeon with abnormal ploidy into the wild may result in reduced fitness due to lowered fertility in the F2 and subsequent generations. Further, there is evidence that ploidy affects reproductive development and caviar yield.

Global Patterns and Gaps in Research on Salinity Tolerance of Inland Fishes

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 400-411, March 2026.
ABSTRACT Freshwater salinization is an emerging threat impacting approximately one‐third of the world's freshwater bodies. However, the salinity tolerance of many inland fishes remains understudied, despite being a crucial factor in determining species distributions and fitness.

Complete Mitogenome of the Russian Sturgeon Acipenser gueldenstaedtii (Acipenseriformes; Acipenseridae) [PDF]

open access: yesFisheries and aquatic sciences, 2009
Sturgeons and paddlefishes are frequently referred to as 'living fossils' among the actionpterygian lineage. They are increasingly facing threats to their existence because of various anthropogenic pressures. In this study, we present the complete mitogenome sequence of the Russian sturgeon Acipenser gueldenstaedtii (Acipenseriformes; Acipenseridae ...

Dam Submergence Flows: An Environmental Flow Prescription Designed to Aid Migratory Fish Passage

open access: yesRiver Research and Applications, Volume 42, Issue 1, Page 19-29, January 2026.
ABSTRACT As part of a holistic ecosystem‐focused set of unified flow prescriptions, natural spring flood events were enhanced with releases from an upstream reservoir on the Cape Fear River in North Carolina (USA) to submerge a series of low‐use, low‐head lock‐and‐dam structures for anadromous fish to move upstream.

Nuclear DNA markers for identification of Beluga and Sterlet sturgeons and their interspecific Bester hybrid

open access: yesScientific Reports, 2017
Sturgeons (Acipenseriformes) are among the most endangered species in the world due to fragmentation and destruction of their natural habitats and to overexploitation, mainly for highly priced caviar.

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
Background. Acipenserid fishes may be divided into three groups in terms of their ploidy levels: 1) 120-chromosomes, 2) 250–270-chromosomes, and 3) about 370-chromosomes.
