Potential hydrological regime requirements for spawning success of the Chinese sturgeon Acipenser sinensis in its present spawning ground of the Yangtze River

Ecohydrology, 2021
Reservoir impoundment often alters the hydrological regimes of the river and consequently leads to the extinction of some sensitive species. This study analysed the spawning response of a critically endangered (CR) species, Chinese sturgeon Acipenser ...

The effects of dam operation on Chinese sturgeon natural propagation

2011 International Conference on Electrical and Control Engineering, 2011
The construction of Gezhouba dam has blocked the migration path of the Chinese sturgeon and forced the formation of a new spawning ground for Chinese sturgeon natural reproduction in the downstream of Gezhouba. The operation of the Three Gorges dam changed the natural course of the river flow and the hydrodynamic characteristics of the Yangtze river ...

A bedform morphology hypothesis for spawning areas of Chinese sturgeon

Environmental Biology of Fishes, 2008
Results from previous research suggested that geomorphic characteristics may be important controlling factors among other microhabitat variables for spawning fish. We investigated the bedform morphology of seven spawning areas (five historic and two present spawning areas) of Chinese sturgeon (Acipenser sinensis) by analysis of relief maps of the ...

Microsatellites assessment of Chinese sturgeon (Acipenser sinensis Gray) genetic variability

Journal of Applied Ichthyology, 2005
Four microsatellites were used to examine the genetic variability of the spawning stocks of Chinese sturgeon, Acipenser sinensis, from the Yangtze River sampled over a 3-year period (1999-2001). Within 60 individuals, a total of 28 alleles were detected over four polymorphic microsatellite loci. The number of alleles per locus ranged from 4 to 15, with

Indexing serum and mucous biochemical parameters of endangered Chinese sturgeon Acipenser sinensis with implications for health assessment.

Journal of Fish Biology
The Chinese sturgeon (Acipenser sinensis) is a critically endangered aquatic fish. Health monitoring and welfare assessments are critical for the conservation of Chinese sturgeon.

Osmoregulation in juvenile Chinese sturgeon (Acipenser sinensis Gray) during brackish water adaptation

Fish Physiology and Biochemistry, 2008
The osmoregulation capabilities of 7-month-old juvenile Chinese sturgeon (Acipenser sinensis Gray) (128.8 +/- 15 g) transferred directly from fresh water (0 per thousand, 46 mOsmol kg(-1)) to brackish water (10 per thousand, 273 mOsmol kg(-1)) were studied over a 20-day period. Changes in serum osmolarity, chloride (Cl(-)), sodium (Na+), potassium (K+)

Hydrodynamic Characteristics of Chinese Sturgeon Spawning Ground in Yangtze River

Journal of Hydrodynamics, 2008
Since the construction of the Gezhouba Dam on the Yangtze River in 1981, it has been found that the Chinese Sturgeon, Acipensor sinensis, performs natural propagation annually in a narrow reach downstream close to the Gezhouba Dam site. This might allow one to better investigate the river hydrodynamic conditions of the Chinese Sturgeon spawning ground.

Chinese Sturgeon Spawning Habitat Horizontal Mean Vorticity Computation and Analysis

2009
The Chinese sturgeon, Acipenser sinensis, is an anadromous protected species. Since the construction of the Gezhouba Dam, its migration pattern has been blocked, and the length of natural spawning site has reduced to less than 7 km. The fish found an alternative spawning ground located in a narrow reach downstream close to the Gezhouba Dam site.

Discriminating Dabry’s sturgeon (Acipenser dabryanus) and Chinese sturgeon (A. sinensis) based on DNA barcode and six nuclear markers

Hydrobiologia, 2015
Both Dabry’s sturgeon (Acipenser dabryanus) and Chinese sturgeon (A. sinensis) are rare fish and listed as first class protected animals in China. Nowadays, an artificial release program has been established as a main way to maintain and restore their wild populations.

Pseudomonas alcaligenes infection and mortality in cultured Chinese sturgeon, Acipenser sinensis

Aquaculture, 2015
Abstract Chinese sturgeon (Acipenser sinensis) is a rare and endangered species, and also an important resource for the sturgeon aquaculture industry in China. Recently, a fatal bacterial disease occurred in farmed Chinese sturgeon. The clinical signs of the diseased fish were systemic blood loss and anemia.
