Cloning and sequence analysis of Sox genes in a tetraploid cyprinid fish, Tor douronensis [PDF]

open access: yes, 2008
A PCR survey for Sox genes in a young tetraploid fish Tor douronensis (Teleostei: Cyprinidae) was performed to access the evolutionary fates of important functional genes after genome duplication caused by polyploidization event.

Revisiting the History of Ornamental Aquaculture in Europe to Understand the Benefits and Drawbacks of Freshwater Fish Imports

open access: yesReviews in Aquaculture, Volume 17, Issue 2, March 2025.
ABSTRACT Ornamental aquaculture and fishkeeping are very popular with millions of enthusiasts worldwide. The number of newly imported fish species for ornamental purposes grew slowly from World War I until the 1980s. It then exponentially increased until now with more than 7900 species and a large number of scientifically undescribed morphotypes.

Fish Genomics and Its Application in Disease‐Resistance Breeding

open access: yesReviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Global aquaculture production has been rising for several decades, with up to 76% of the total production from fish. However, the problem of fish diseases is becoming more and more prominent in today's context of pursuing sustainable aquaculture.

Toward a Phylogenetic Taxonomy of Sturgeons (Acipenseriformes: Acipenseridae)

open access: yesBulletin of the Peabody Museum of Natural History
Acipenseriformes, comprising sturgeons and paddlefishes, is one of the three ancient and species-poor living lineages of non-teleost Actinopterygii. Here, we use DNA sequence and morphological data to investigate the phylogenetic relationships of sturgeons and produce a phylogenetic basis for the taxonomy of Acipenseridae.

Too Hot to Handle: A Meta‐Analytical Review of the Thermal Tolerance and Adaptive Capacity of North American Sturgeon

open access: yesGlobal Change Biology, Volume 30, Issue 11, November 2024.
Combining published data gathered from the field and in the laboratory, we examined how temperature impacts North American sturgeon to gauge how these threatened and endangered species will fare in an increasingly warming world. We found that, in response to prolonged warming, North American sturgeon can increase their upper thermal limit more so than ...

Effect of different oxygen levels on growth performance, stress response and oxygen consumption in two weight groups of great sturgeon Huso huso [PDF]

open access: yes, 2013
In the present study, different oxygen levels were examined in two weight groups of great sturgeon Huso huso including small size (with initial weight 280.9 ± 49.2 g) and large size (with initial weight 1217.9 ± 138.1 g). The fish were kept in hypoxia (2-

The fate of the duplicated androgen receptor in fishes: a late neofunctionalization event?

open access: yesBMC Evolutionary Biology, 2008
Background Based on the observation of an increased number of paralogous genes in teleost fishes compared with other vertebrates and on the conserved synteny between duplicated copies, it has been shown that a whole genome duplication (WGD) occurred ...

Multiple source genes of HAmo SINE actively expanded and ongoing retroposition in cyprinid genomes relying on its partner LINE

open access: yesBMC Evolutionary Biology, 2010
Background We recently characterized HAmo SINE and its partner LINE in silver carp and bighead carp based on hybridization capture of repetitive elements from digested genomic DNA in solution using a bead-probe 1.

Tree of Sex: A database of sexual systems [PDF]

open access: yes, 2014
The vast majority of eukaryotic organisms reproduce sexually, yet the nature of the sexual system and the mechanism of sex determination often vary remarkably, even among closely related species. Some species of animals and plants change sex across their
