Submerged karst landforms observed by multibeam bathymetric survey in Nagura Bay, Ishigaki Island, southwestern Japan

Bailly, Denis.

Coastal fisheries and marine cultures developed under strong biological, economical and social constraints. Among others are limitation of space and resources, limited availibility of capital, hardship of work,... Industrial, urbanistic and touristic development add to these constraints in coastal areas. Coherent scheme for coastal fisheries management, capture and culture, is of an urgent need. In renewable resources and environnement economics, depletion and pollution resulting from common ownership have been the core of the theory about fisheries management. The chronology of Japanese coastal fisheries management system shows a different approach. In law and decision making, social and economic consequences of conflictual uses and of their regulation...

Fisheries women groups in Japan: a shift from well-being to entrepreneurship

Kan, Hironobu; Urata, Kensaku; Nagao, Masayuki; Hori, Nobuyuki; Fujita, Kazuhiko; Yokoyama, Yusuke; Nakashima, Yosuke; Ohashi, Tomoya; Goto, Kazuhisa; Suzuki, Atsushi.

Submerged tropical karst features were discovered in Nagura Bay on Ishigaki Island in the southern Ryukyu Islands, Japan. The coastal seafloor at depths shallower than similar to 130 m has been subjected to repeated and alternating subaerial erosion and sedimentation during periods of Quaternary sea-level lowstands. We conducted a broadband multibeam survey in the central area of Nagura Bay (1.85 x 2.7 km) and visualized the high-resolution bathymetric results over a depth range of 1.6-58.5 m. Various types of humid tropical karst landforms were found to coexist within the bay, including fluviokarst, doline karst, cockpit karst, polygonal karst, uvalas, and mega-dolines. Although these submerged karst landforms are covered by thick postglacial reef and...

Women’s groups in rural fishery areas were established in the mid-1950s. By 1959, they became integrated in local Fishery Cooperative Associations as parallel organizations. These Fisheries Cooperative Associations, established in 1948, represent all fishers in Japan, who are primarily men. The purpose of the women’s groups was to provide well-being by improving the living conditions of families and communities. While men were busy building the production facilities and the cooperatives, women organized themselves to protect and improve the everyday life of families. From 1995 and the World Conference on Women in Beijing, China, some of these women groups ran economic entrepreneurial activities with the financial support of the State through the...

Synthesis on moored FADs in the North West Pacific region

Current, catch and weight composition of yellowfin tuna with FADs off Okinawa island, Japan

Kakuma, S.

In early 1980s, fad fisheries were introduced from the Philippines to Japan, mainly to Okinawa. The fisheries have well developed becoming one of the main fisheries in Okinawa where 210 fads are approved to deploy in 1999. The annual catch by roughly 1 000 boats (most of them are small) is 2500-4000 mt; average catch from one fad is about 20 mt; average catch by one boat on one day is 73 kilogrammes. fads are also important for easing the fishing pressures on bottom fish stocks. Most of the fads were deployed and managed by local fishermen's groups that have improved the structures of the system to withstand typhoons. The catches are strongly depending on the sites, usually the farther offshore, the better the catches. A variety of fishing methods are...

Sea trials and supporting technologies of manned submersible "Shinkai 6500".

Kakuma, S.

Yellowfin tuna (Thunnus albacares) is a main target for the fisheries at Fish Aggregating Devices (FADs) off the south of Okinawa island. Catch and weight composition of the tuna were monitored at a fisheries cooperative market from 1989 to 1998. Some distinct weight groups (considered to represent cohorts) appeared in the catch and the weight of these groups increased monthly - presumably as individual tuna grew. Although small, light weight fish were caught year-round, the 2 kg weight group that was recruited in May grew to about 15 kg by May of the next year. There was a significant seasonal cycle in the monthly catches. The catch of heavier weight groups decreased in winter indicating the tuna moved out of this FAD area. At one of huge FADs (Nirai),...

Climate reconstruction based on GDGT-based proxies in a paleosol sequence in Japan: Postdepositional effect on the estimation of air temperature

Iwai, Y; Nakanishi, T; Takahashi, K.

After the four years of development of the modern maximum depth submersible, JAMSTEC has successfully completed the training dives of "SHINKAI 6500", a new manned submersible whose maximum operating depth is 6,500 meters, from June to October in this year. "SHINKAI 6500" was constructed by Kobe Shipyard and Machinary Works of Mitsubishi Heavy Industries Ltd. (MHI) and marked 6,465m and 6,527m dives in the Japan Trench during the sea trials with the support "YOKOSUKA" (built by Kawasaki Heavy Industries Ltd.) in August 1989. This paper presents the results of the sea trials, training dives and the features of "SHINKAI 6500" with her supporting technologies.

Yamamoto, Yasuto; Ajioka, Taku; Yamamoto, Masanobu.

We investigated branched and isoprenoid glycerol dialkyl glycerol tetraethers (GDGTs) in surface soils and a paleosol sequence to understand the effects of environmental and postdepositional factors on branched GDGT composition in different soil types and to reconstruct the past changes in the mean annual air temperature (MAAT) in southwestern Japan during the last 15 ka. The estimated MAAT was overestimated by 6 degrees C and 2 degrees C when the global and regional soil calibrations were applied, respectively. Additionally, the estimated MAAT increased downward by a maximum of 4 degrees C in the upper 30 cm of the soil sequence. This is likely to reflect the addition of newly produced branched GDGTs in subsurface soils. The estimated MAATs in a paleosol...

Lobatolampea tetragona gen. nov. & spec. nov. was collected from coastal waters of Ise Bay, near Toba, Pacific coast of middle Japan. It assumes a medusoid bell-shape when floating, but is nearly discshaped when resting on the bottom. It is characterized by four C-shaped gonads present on the distal part of the subpharyngeal meridional canals, beyond the oral end of the comb rows. “Primitive” oral lobes are also formed and ctenes are found at the site of the presumptive auricles. The morphology of this species differs from any previously described larval or adult form, and is intermediate between the orders Cydippida and Lobata. The larvae are of the cydippid type.

A redescription of Zetorchestes saltator Oudemans, 1915 is given. In addition to that, two new Zetorchestes-species from New Guinea (Z. novaguineanus spec. nov., Z. vanderhammeni spec. nov.) and one new species from Japan (Z. aokii spec. nov.) are described in this paper. These four and some other similar species are compared in table 1. In the redescription and the descriptions attention is paid to the intraspecific morphological variability of body size, the shape of the anterior edge of the lamella, the position of the notogastric hair la, the number of the notogastric hairs, the number and position of the genital, anal and adanal hairs, and the shape of the edge of the lamella on femur II. It seems likely that the Zetorchestes-species from New Guinea...

Because Eurasian samples of Neoerysiphe collected on the Asteraceae were not identical in morphology, the molecular and morphological differences among these specimens were compared with those of the American N. cumminsiana. Neoerysiphe on Asteraceae was found to consist of at least four different species. Three of them are described as new species, viz. N. hiratae, N. joerstadii, and N. nevoi. Neoerysiphe hiratae is a Japanese species parasitizing hosts belonging to the genera Cacalia and Ligularia (tribe Senecioneae). Neoerysiphe joerstadii was found in Israel on Phagnalon rupestre (tribe Gnaphalieae). Neoerysiphe nevoi was recorded in Israel and Ukraine on a number of hosts in different genera but all belonging to tribe Cichorieae. Thus, Eurasian...
