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

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.

Global introductions and environmental impacts of freshwater megafish

open access: yesGlobal Change Biology, Volume 30, Issue 4, April 2024.
Of the 134 extant freshwater megafish species, 46% have been introduced outside of their native ranges. Over 50% of the alien megafish species with sufficient data to evaluate the severity of their environmental impacts have caused population declines or even extirpations of native species.

Environmental DNA reveals the ecology and seasonal migration of a rare sturgeon species in the Ural River

open access: yesEnvironmental DNA, Volume 6, Issue 2, March–April 2024.
Environmental DNA technology has been used to identify rare sturgeons in the Ural River. The study found sturgeons at all sites in spring and autumn, confirming their semi‐anadromous ecology. This is the first documented eDNA detection of sturgeon specimens in the Ural River.

A newly developed cloning technique in sturgeons; an important step towards recovering endangered species

open access: yesScientific Reports, 2019
Several steps of sturgeon somatic cell nuclear transfer (SCNT) have been recently established, but improvements are needed to make it a feasible tool to preserve the natural populations of this group of endangered species.

Food availability influences angling vulnerability in muskellunge

open access: yesFisheries Management and Ecology, Volume 31, Issue 1, February 2024.
Abstract Reduced food availability increases the capture of several fish species, although the mechanisms responsible for how food resources result in increased capture are undefined. Our objective was to quantify the mechanism by which food availability might influence the angling vulnerability of muskellunge (Esox masquinongy).
