  • The forming of fishing ground and the population ecological characteristics of yellowtail, Seriola quinqueradiata, in the coastal waters off Gim-nyeong of Jeju Island were investigated. The stock of yellowtail, Seriola quinqueradiata, between Jeju Island and coastal areas of the East Sea is probably the same. Water temperature probably is a major factor for controlling distribution of yellowtails in deeper, offshore areas off Jeju Island. However, the major factor that determines aggregation of yellowtails in coastal areas of Jeju Island, especially off Gim-nyeong is probably strong tidal currents driven by distribution of yellowtails rather than hydrological conditions such as Yellowtails collected off Jeju Island were from 1 to 4yrs old and about 50% of them were $1^{-yr}$ old, probably indicating overfishing. Jack mackerel was the major prey item for yellowtails off Gim-nyeong from October to March, suggesting concurrence of the two species.

  • Bottlenose dolphins (Tursiops sp.) commonly inhabit Korean waters, including the coastal waters of Jeju Island. However, their taxonomic position was unclear because of the validity of this genus. The genus Tursiops has recently been determined to comprise two species: the common bottlenose dolphin (Tursiops truncatus) and the Indo-Pacific bottlenose dolphin (Tursiops aduncus). To confirm the taxonomic position of bottlenose dolphins frequenting the coastal waters of Jeju Island, the external morphology and osteology of specimens from Jeju Island were examined. Photographs of free-swimming individuals were also used for determining external morphological characters. The cranial and meristic measurements fell within the ranges of T. aduncus. Osteological ratios were also consistent with those of T. aduncus. The presence of a prominent ventral spot was observed among some individuals. As a result, the dolphins mainly distributed in the coastal waters of Jeju Island were identified as Indo-Pacific bottlenose dolphins (T. aduncus) in terms of their cranial characters and ventral spotting. We propose a new Korean name, 'Nambang-keun-dol-go-rae'.

  • The purpose of this study is to explore the history of the relationships between Japan and the Pacific Island Nations in the context of its ocean policy, and to survey the current situation. Particularly, this paper inquires into how Japan's maritime policy, nuclear policy, and official development assistance policy have affected relationships with countries in this region. Firstly, this paper gives a brief overview of the socio-political situations of Pacific Island Nations. Secondly, the history of the 'Southward Advance Theory' adopted as national policy by Japan in the Meiji era is summarized. Thirdly, how Japan successfully re-entered this region despite conflicts surrounding the nuclear issue after the Second World War is explored. Lastly, this paper investigates how official development assistance and PALM (Pacific Island Leaders Meeting) helped to develop relations between Japan and the Pacific Island Nations.

  • In this paper, the nature-based tourism is described as one of the tools to achieve sustainable development in small islands. The study was carried out at Ayer, Bidadari and Onrust Islands of Kepulauan Seribu chains at Jakarta Bay, Indonesia. While the historical records show that previous uses of such islands have started at sixteen century, tourism uses was started at the beginning of 1970s. Among nature-based tourism destination in Kepulauan Seribu chains, these islands are the famous destinations and received a lot of tourists. Tourism growth at these islands has stimulated development of numerous tourism facilities and infrastructure to meet visitor satisfaction. It is observed in this study that island's site-plan destination design has contributed to the successful and sustainability of tourism in small island. The key success lies on the successful integration and implementation of three substantial perspectives into practices, namely economic, ecosystem and social perspectives. First, in order to enhance economic benefits, a site-plan design allowing floating cottages establishment to extent room availability, to build strong images as tropical paradise islands, and to enhance tourist satisfaction with the objectives of improving income and sustaining tourist loyalty to the destination. This design is also reducing land risk from tourism impact and it becomes the significant key of second perspective, the ecosystem perspective. Moreover, the ecosystem perspective has been implemented through native vegetation preservation that led island's wildlife conservation and became potential tourism attraction. The design also develops effective mechanism to manage and regulate visitor flows by establishing visitor track corridors. In implementation, such corridor plays an important role to reduce tourist density in single places and therefore become instrument to reduce severe visitor impact to wildlife, vegetation and heritages of islands. Third, the social aspect of development allowing heritages to conserve and furthermore serve numerous benefits for education, socio-political, culture, and historical studies. Through this study, it is clear that the success of these islands to continuous tourism growth lies on the island's vision to integrate economic, ecosystem and social perspectives on tourism development.

  • Two months old Fayoumi, Rhode Island Red, and Fayoumi ${\times}$ Rhode Island Red chickens were reared upto 512 days of their age in the villages surrounding Bangladesh Agricultural University in order to study comparative performances of the 3 genetic groups with or without extra feeding to scavenging system of rearing and also, to study the suitability of these breeds reared under the rural condition. Fayoumi attained earlier sexual maturity (238.5 vs 262.5 d) and laid more eggs than other breeds/types. Rhode Island Red produced the largest eggs, but mortality rates were highest and Fayoumi showed greatest resistance to diseases. Crossbred was heaviest (1,275 g at 247.5 d of age) and had highest hatchability than parental breeds. Age at sexual maturity (247.5 d), 50% egg production, peak production and mortality in crossbreds were mostly influenced by sire Fayoumi but for the egg weight and body weight, the effect of the dam Rhode Island Red was significant. Extra feeding was found more beneficial to the chickens irrespective of breeds and types. The crossbred Fo ${\times}$ RIR chickens were found more suitable under rural scavenging system than the exotic breeds, Fayoumi and Rhode Island Red in the rural areas of Bangladesh.

  • Islands are vulnerable to outer influences due to their small size and isolation. Tourism often becomes an important development focus because of their unique culture and nature. Jeju-do, as well as other islands, has experienced such development mostly led by central government, and the regional change was understood as the outcome of global influences without much concern with the local response or strategy. Thus, vulnerability has been the key theme in island development studies. This paper examines the current state of island development as an outcome of locals' alternating strategy in which the islanders accept the central government's plan, but express their demands to modify them. It is reflected in the electoral preference for ruling or oppositional parties, local movements against central government's development plans, and the spatial organization of tourism sites from a few growth centers to more dispersed, balanced development. These suggest that the current state of island development is not derived from unidirectional global forces, even if islands are peripheral. Rather, it is the outcome of an alternating strategy of Jeju locals accepting the central government development plans while managing them for local benefits.

  • Recent conditions in North Sulawesi Province (NSP) have become favorable for the development of tourism. In this paper, we present the recent status of biodiversity and tourism in NSP as a basic consideration towards integrative biodiversity conservation strategy. Overall, biological accounts suggest that NSP is important for the world biodiversity conservation program. NSP's biodiversity makes the area a major nature-based tourism (ecotourism) site in the world. Development of diverse tourism programs in NSP has provided new opportunities for balancing development and conservation of regional ecosystems. However, the excessive tourism growth in some particular areas in NSP has been identified as the primary factor of environmental degradation. Nowadays, biodiversity of North Sulawesi regions are suffering from the number of tourist impacts and facilities. Based on those conditions, tourism planning and development in NSP is needed to formulate a proper strategy to protect the ecosystem and biodiversity from degradation and extinction. This will be a new challenge of sustainable island tourism development and biodiversity conservation in NSP.
