Abstract
Among the edible species, jellyfish Rhopilema esculentum, is one of the most abundant and important fishery species in China. The jellyfish fishery is characterized by considerable fluctuations in catch and a very short fishing season. In this article, we first review the research results on the biology of R. esculentum, which previously were published in Chinese, as related to the jellyfish enhancement and fishery. Next, we review results from enhancement experiments conducted from 1984 to 2004, with the aims of stabilizing and increasing catch. During 2005 and 2006, stock enhancement of R. esculentum was carried out on a large scale for the first time in Liaodong Bay, China, where 414 million juvenile jellyfish (umbrella diameter > 1 cm) were released. We present results of these enhancements, including the survey methods, catch prediction, enhancement assessment, and fishery management. In 2005 and 2006, the recapture rate of released jellyfish was 3.0 and 3.2%, respectively. The fishermen earned ¥ 159 million during the 2 years. The ratio of the input (cost of culturing juvenile jellyfish) to the output (value of the sales) was about 1:18. The high commercial value of R. esculentum enhancement in Liaodong Bay makes this a very successful enterprise.
