I always see those bright bubbly things washed up on the shore. and you don't have to get stung by them. if that bubble pops and you get the liquid on you (like from stepping on one) you still feel the burn. and they aren't even supposed to be in season!! not in the summer. one time I went in the water, looked down, and was surrounded. I never ran so fast to the shore in my life. "We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time." - T. S.

The breeding Ground is close to Shanghai and the Water is saturated with Human Products Abstract Jellyfish blooms can cause extreme problems to both marine ecosystems and human enterprises. In the Sea of Japan, smacks of the jellyfish Nemopilema nomurai have presented challenges because their population has been growing at a rapid rate. These circumstances are affecting many aspects, both within the marine ecosystem and in its dependent economy. Although the Sea of Japan has faced extreme blooms before, they have usually only occurred every 40 years. Since 2002, a bloom has been present almost every year. This paper explores the complexity of the problem and suggests various management ideas. Introduction The Sea of Japan is located to the northwest of Japan, between it and the Asian continent. The lands around the sea create a relatively closed body of water (figure 1). Factors such as pollution and over fishing have a much greater effect in a closed basin than in the open ocean. In recent years, a common jellyfish, Nemopilema nomurai, has experienced population explosions (blooms) that have caused hardships in the fishing industry, affected other ocean reliant businesses, and changed the local ecosystem. Massive jellyfish blooms are a big problem in the Sea of Japan. Although the N. nomurai jellyfish population has probably been present in the Sea of Japan for many thousands of years, they have rarely been associated with problems. During the twentieth century, there were only a few documented jellyfish blooms. This is drastically different than the current rate of almost one bloom per year since 2002. This paper will explore the biology and ecology of the N. nomurai. The movement of larval medusae from their breeding grounds in the Yellow Sea to the Sea of Japan will be described. The typical reasons for jellyfish blooms will be examined. The direct effects on commercial fishing and other parts of the ecosystem will be discussed. In order to address this problem, we feel that a management plan is necessary. Without action, this problem is likely to persist and have negative implications for both the environment and Japan's economy. [link to seagrant.uaf.edu (secure)] |
