Vorticity Characteristics of Chinese Sturgeon Spawning Ground
2009Since the construction of the Gezhouba Dam in 1981, it has been found that Chinese sturgeon, Acipensor sinensis, performes natural propagation annually in a narrow reach downstream close to the Gezhouba Dam site. This would allow one to better investigate what the hydraulic and morphologic conditions of a river can meet the Chinese sturgeon spawning ...

Intelligent Detection Method for Chinese Sturgeon Based on YOLOv8
Computer Science and ApplicationIn response to the problems of severe occlusion, near background color, and inconsistent target size in underwater Chinese sturgeon video images, an EMA attention mechanism is introduced based on the YOLOv8 detection algorithm.

Two-dimensional habitat modeling of Chinese sturgeon spawning sites
Ecological Modelling, 2010Abstract Since the construction of the Gezhouba Dam in the 1980s, the number of Chinese sturgeon in the Yangtze River has been rapidly declining. The Gezhouba Dam has cutoff the migration path of these sturgeon, resulting in an overall reduction of suitable sturgeon habitat.

Neuropeptides and hormones in hypothalamus-pituitary axis of Chinese sturgeon (Acipenser sinensis)
General and Comparative Endocrinology, 2023The hypothalamus and pituitary serve as important neuroendocrine center, which is able to secrete a variety of neuropeptides and hormones to participate in the regulation of reproduction, growth, stress and feeding in fish. Chinese sturgeon is a basal vertebrate lineage fish with a special evolutionary status, but the information on its neuroendocrine ...

Remote Sensing
The Chinese sturgeon (Acipenser sinensis), a critically endangered anadromous fish species, spends over 90% of its life cycle in marine habitats, yet research on its marine ecology and habitat requirements is limited due to sparse data.

Ontogenetic Behavior and Migration of Chinese Sturgeon, Acipenser sinensis
Environmental Biology of Fishes, 2002The Chinese sturgeon, Acipenser sinensis, is an anadromous protected species that presently only spawns in the Yangtze River. Using laboratory experiments, we examined the behavioral preference of young Chinese sturgeon to physical habitat (water depth, illumination intensity, substrate color, and cover) and monitored their downstream migration ...

Extraction, purification and characterisation of chondroitin sulfate in Chinese sturgeon cartilage
Journal of the Science of Food and Agriculture, 2013AbstractBACKGROUNDChinese sturgeon (Acipenser sinensis), a rare species, is an important fishery resource in China. To save this species from overfishing, damming and pollution, artificial propagation has been developed rapidly in recent years. However, the cartilage from Chinese sturgeon, which contains an abundance of chondroitin sulfate (CS), is ...

The effects of dam operation on Chinese sturgeon natural propagation
2011 International Conference on Electrical and Control Engineering, 2011The 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 ...
