biological, and energy resources. JAMSTEC was founded in 1971 to promote Japan's marine science and technology, focusing on R & D, training, technical information services, and operation and maintenance of public marine facilities. Projects include a deep (6500 m) submersible scheduled for launch in 1989, new earthquake prediction studies. recovery of uranium from seawater, use of deep seawater for biological production, and studies utilizing Kaiyo, the world's largest SWATH vessel, and Kaimei, a large-scale wave power generator. JAMSTEC, Yokosuka, Japan. (lit) 87:5263 Nemoto, Takahisa, 1987. Japan's Ocean Research Institute. Oceanus, 30(1):48-54. Founded in 1962 and supported by Japan's Ministry of Education, Science and Culture, the Ocean Research Institute operates 15 research divisions, a shore laboratory, and two research vessels. Activities include studies in physical oceanography, marine meteorology, submarine geophysics, marine chemistry, and fisheries biology and ecology. An extensive Antarctic research program is conducted at Syowa Station and the institute coordinates many international programs. Ocean Res. Inst., Tokyo, Japan.

The central Japanese government in conjunction with local authorities has developed various regional programs for the utilization of the 200-mile Exclusive Economic Zone surrounding the island nation, which is twelve times larger than the country's land area. Among the utilization goals under study are: offshore man-made islands; marine multi-zones for recreational activities and urban facilities; sea ranching (mariculture); marine community polis to integrate the needed technologies; and an aqua

Research on ciguatera fish poisoning has expanded significantly over the last decade. However, the general state of knowledge on ciguatera remains relatively poor, both in terms of toxin chemistry and the physiological ecology of the causative dinoflagellates. One objective of this review is to place the many recent papers on ciguatera in a current perspective that not only identifies common observations or conclusions, but also accentuates those areas that require more research effort to resolve disagreements or contradictions.

Lab., Woods Hole, 172(1):128-131. Nine species of benthic dinoflagellates collected in subtropical waters were cultured, extracted, and tested for mouse lethality, ichthyotoxicity, and hemolytic activity. Hemolytic activity was detectable in all species, but the activities of Amphidinium carteri, A. klebsi, and Gambierdiscus toxicus were outstanding. G. toxicus showed the most potent mouse lethality. Two potent toxins against mice were isolated from Proroeentrum lima. Faculty of Agric., Tohoku Univ., 1-1 Tsutsumidori-Amamiyamachi, Sendal 980, Japan.
