ABSTRACT

Among the edible jellyfish species, Rhopilema esculentum Kishinouye, 1891, is one of the most abundant jellyfish species consumed. Therefore, this jellyfish species is an impor - tant fisheries source in China. The jellyfish fisheries in China show annually considerable fluctuations and have a very short season. In the chapter, we firstly try to review the natural ecology of R. esculentum , which includes the distribution and migration, growth model, and survival rate in the Liaodong Bay (LDB) based on the results of our field studies for more than 20 years. Secondly, we focus on reviewing the jellyfish fishery and population dynamic in the LDB. Thirdly, we emphasize the themes, including the survey methods, catch prediction, enhancement assessment, and fishery management, based on our survey results from 2005 to 2010. Finally, we present our field and experiment results of resource restoration. The high commercial value of R. esculentum enhancement in the LDB has made this a very successful enterprise.
