Abstract:
Beach is a common and vulnerable coastal ecosystem with huge ecological service functions. Due to the multiple impacts of climate change and human activities, beach ecosystem has been seriously damaged. Beach nourishment is an effective approach to p...
Hydrodynamic performance study of a land-based OWC under the action of irregular wave
Fu Lei, Ning Dezhi, Wang Rongquan, Robert Mayon
2024, 46(1): 101-110. doi: 10.12284/hyxb2024005
Abstract:
To study the hydrodynamic performance of an oscillating-water-column (OWC) wave energy converter in a real sea, a two-dimensional nonlinear numerical model of the interaction between irregular waves and a land-based OWC device is developed based on t...

2024, 46(1): 39-52. doi: 10.12284/hyxb2024018
Abstract:
The Sardinops melanostictus and the Scomber japonicus are important economic species in the northwestn Pacific Ocean, and exploring the correlation between their habitat changes is conducive to the rational development and management of fishery resou...
Study on the diel vertical migration characteristics of the deep scattering layer in the southwestern Indian Ocean
Wan Shujie, Chen Xinjun
2024, 46(1): 53-63. doi: 10.12284/hyxb2024016
Abstract:
Based on the data from 56 acoustic survey sections in the southwestern Indian Ocean from 2011 to 2020, a total of 201 diel vertical migration were observed. The characteristics of diel vertical migration of the deep scattering layer and its spatiotem...
Assessing the impacts of fishing on fish community in marine ranch of the Wuzhizhou Island based on size-spectrum model
Qiao Jiale, Li Xiaodong, Li Jianlong, Xia Kaiming, Liu Qi, Wang Yingbin
2024, 46(1): 64-76. doi: 10.12284/hyxb2024020
Abstract:
The concept of ecosystem-based fisheries management has been widely recognized, but it’s application in the construction of marine ranch is still very rare. In this study, based on the data from a bottom trawl survey of fishery resources conducted in...
Comparison of the pyloric caecum microbiota community structure between the wild and farmed Larimichthys crocea in Sansha Bay
Zhang Yuting, Zhang Ruirui, Pan Feifei, Pan Youhao, Li Cong, Lin Hua, Chen Shixi, Mu Jingli
2024, 46(1): 77-87. doi: 10.12284/hyxb2024012
Abstract:
The semienclosed pyloric caecum of Larimichthys crocea is an ideal organ to perform the host source tracking, as it containes several local bacteria colonized during early development. The alpha diversity, relative abundance of core bacteria and netw...
Effects of CO2-driven seawater acidification on tissue, immune and antioxidant enzyme activity and transcription levels of Ruditapes philippinarum
Lin Yi, Chen Qiang, Zhou Sishun, Kong Lumin, Huang Zhangfan
2024, 46(1): 88-100. doi: 10.12284/hyxb2024010
Abstract:
The ocean acidification effect is increasing with the large amount of CO2 emissions. To investigate the effects of future seawater acidification on Ruditapes philippinarum, a control group (pH = 8.1) and acidification group (pH = 7.7, 7.1 and 6.4) we...
