The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP) is an endangered species endemic to the Yangtze River in China, and it is the only freshwater whale in the genus Neophocaena.…


Wild harbour porpoises startle and flee at low received levels from acoustic harassment device

Elmegaard, Siri L.; Teilmann, Jonas; Rojano-Doñate, Laia; Brennecke, Dennis; Mikkelsen, Lonnie; Balle, Jeppe D.; Gosewinkel, Ulrich; Kyhn, Line A.; Tønnesen, Pernille; Wahlberg, Magnus; Ruser, Andreas; Siebert, Ursula; Madsen, Peter Teglberg
Scientific Reports (2023)

Acoustic Harassment Devices (AHD) are widely used to deter marine mammals from aquaculture depredation, and from pile driving operations that may otherwise cause hearing damage. However, little is known about…


Diving on damage – The muscle transcriptome of parasitic infested harbor porpoises (Phocoena phocoena) hints at oxidative stress but not hypoxia

Dönmez, Eda Merve; Siebert, Ursula; Fabrizius, Andrej
Frontiers in Marine Science (2023)

The only native cetacean in German waters, the harbor porpoise (Phocoena phocoena), is impacted by numerous pathological lesions in the respiratory tract mainly caused by parasites or bacteria. Although harbor…


Variation of blubber thickness of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) in human care: Adaptation to environmental temperature

Tang, Bin; Hao, Yujiang; Wang, Chaoqun; Deng, Zhengyu; Shu, Guilin; Wang, Kexiong; Wang, Ding
Water Biology and Security (2023)

Blubber thickness (BT) has a seasonal pattern in most small cetaceans in temperate and polar regions, which may be a crucial adaptive mechanism in response to environmental temperature changes. However,…


Social, reproductive and contextual influences on fecal glucocorticoid metabolites in captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) and bottlenose dolphins (Tursiops truncatus)

Serres, Agathe; Robeck, Todd; Deng, Xiaojun; Steinman, Karen; Hao, Yujiang; Wang, Ding
Journal of Zoological and Botanical Gardens (2020)

Although the use of fecal glucocorticoid metabolite (FGCM) measurements as non-invasive biomarkers for the stress response in mammals has increased, few studies have been conducted in odontocetes. We investigated if…

Marine Mammal Science (2018)

...Milk protein composition likely varies between lactation stages in the finless porpoise (Zeng et al. 2017). Zeng et al. (2017) indicate that crude protein concentration is much higher in colostrum…


Ultrasonography of mammary glands in finless porpoises (Neophocaena asiaeorientalis) at different reproductive stages

Zeng, Xianyuan; Huang, Shiang-Lin; Hao, Yujiang; Wang, Ding; Ji, Junhua; Deng, Xiaojun; Nabi, Ghulam
Marine Mammal Science (2017)

...The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), endemic to the middle and lower reaches of the Yangtze River and the adjoining Poyang and Dongting lakes (Gao and Zhou 1993), is…
