1Study on the Carry Capacity of Edible Jellyfish Fishery in Liaodong Bay显示文摘Jellyfish fishing is a special type of fishery that mainly exists in some countries of East and Southeast Asia. China has the largest jellyfish fishery yield in the world with an annual harvest of around 300 thousand tons. Liaodong Bay is the most important jellyfish fishery ground in China. However, due to the high benefits of jellyfish fishery, which leads to illegal and out-of-season jellyfish fishing occurring each year in Liaodong Bay. Illegal jellyfish fishery in Liaodong Bay is a typical example of the tragedy of the commons. The key problem is that fishermen seek to an illegally initiate jellyfish fishing as early as possible. In this paper, basing on the data of edible jellyfish's biology and ecology, we mainly analyzed the history of jellyfish fishery in China, especially in Liaodong bay, and then we calculated the carry capacity of edible jellyfish in Liaodong Bay which is about 300 thousand tons one year. This number is equal to the recent annual yield of edible jellyfish in China. Furthermore, basing on the carry capacity and reasonable quotas price analysis, we set up a Jellyfish fishing quotas and deficit quotas buyback system which could be a suitable and effective solution for jellyfish fishery management and development in Liaodong Bay at the underlying roots. Although China is the first country with edible jellyfish aquaculture, the annual yield of jellyfish aquaculture is only one fifth of jellyfish fishing. So, there is a very bright developing prospect about edible jellyfish aquaculture in China.YOU Kui BIAN Yongning MA Caihua CHI Xupeng LIU Zhiqiang ZHANG Yuyu 2016Journal of Ocean University of China2016,15,3:1
2Degree of ontogenetic diet shift and trophic niche partitioning of Euphausia superba and Thysanoessa macrura are influenced by food availability显示文摘Euphausia superba and Thysanoessa macrura are dominant krill species in the Southern Ocean and their habitats are often overlapped reportedly.Studies of the feeding strategies of these two krill species will help us better understand the coexistence mechanisms and estimate the roles that krill played in the food web of the Southern Ocean.The trophodynamics of E.superba and T.macrura at different ontogenetic stages(furcilia,juvenile,adult)were studied using fatty acid and stable isotope biomarkers in the samples collected in Amundsen Sea during austral summer of 2017/2018 and 2018/2019.Diatoms like Fragilariopsis spp.was the most abundant phytoplankton species in the summer of 2017/2018,while the abundance of phytoplankton in the summer of 2018/2019 was dominated by Phaeocystis sp.The gradual increase of the carnivorous index 18꞉1n-9/18꞉1n-7 with ontogeny of both species in 2018/2019 indicated more carnivorous feeding of adults compared with juveniles and larvae.Meanwhile,greaterδ15N values of T.macrura than that of E.superba were more significant in the juvenile and adult stages during the summer of 2018/2019.Our results indicate that the trophic niche differentiation between the two krill species appeared in postlarval stage and can be influenced by food availability.Compared with E.superba,T.macrura was more prone to feed omnivorously or carnivorously responding to food availability.Zhipeng PANG Xupeng CHI Zhihui SONG Haibo LI Yunyan CHEN Guang YANG 2023Journal of Oceanology and Limnology2023,41,3:0
