  • Three categories (freshwater, amphidromous, and marine fishes) of Taiwanese fishes are analyzed on the basis of zoogeographic elements, viz. China element, Indo-China element, Indo-West Pacific element, Indo-Pacific element, North-Pacific element, Japan-Oregon element, and circumtropical element. Freshwater fishes, which include the China and Indo-China elements, are distributed on part of the boundary area between the Palaearctic and Oriental regions of Wallace (1876). Diadromous fishes include the North-Pacific, Indo-China and Indo-West Pacific elements. Taiwanese salmon, a landlocked (initially diadromous) species that became established in Taiwan between 0.5 my B.P. and the early Pleistocene, is recognized as a distinct taxon included within the Oncorhynchus masou complex, which comprises here three species and two subspecies, viz. Oncorhynchus masou masou (Sancheoneo, Songeo, Sakura-masu or Yamame), O. masou ishikawae (Satsuki-masu or Amago), O. sp. (Biwa-masu), and O. formosanus (Taiwanese salmon), based on molecular, morphological and biological studies. Marine fishes are discussed under the following headings, brackish-water fishes (fishes of brackish waters and seas adjacent to continental coastlines, North Pacific and Indo-West Pacific elements; fishes of brackish waters and seas primarily around islands, Indo-West Pacific element), reef fishes (fishes of inshore reefs along continental coastlines from 0 to ca.100 m depth, Indo-West Pacific element; fishes of inshore reefs primarily around islands from 0 to ca.100 m depth, Indo-West Pacific element; fishes of offshore reefs along continental shelf edges from ca.150 to 300 m depth, circumtropical and Indo-Pacific elements; fishes of offshore reefs primarily around islands from ca.150 to 300 m depth, Indo-Pacific element), demersal fishes (fishes on continental shelves shallower than ca.150 m depth, Indo-West Pacific and Japan-Oregon elements; fishes on edges and upper continental slopes from ca.150 m to 500 m depth, Indo-West Pacific, Indo-Pacific, and circumtropical elements; fishes on lower continental slopes to abyssal plains from ca.500 m to 6,000 m depth, circumtropical element and rarely Indo-Pacific element), pelagic fishes (epipelagic fishes from 0 to ca.150 m depth, Indo-West Pacific, Indo-Pacific or circumtropical elements; meso- and bathypelagic fishes from ca.150 to 3,000 m depth, circumtropical element). The distribution of Taiwanese marine fishes are influenced by the Kuroshio Current, low-salinity and low-temperature waters from mainland China, and sea-bottom topography.

  • The 9th Indo-Pacific Fish Conference (IPFC9) was held in Okinawa, Japan from 24th to 28th June 2013. Five hundred and thirty two delegates from 36 countries/regions around the world attended. The Conference took place with a welcome address by Dr. Keiichi Matsuura in the Laguna Garden Hotel next to the Okinawa Convention Center in the evening of 23rd June 2013, one day before the official start of the IPFC9. The winners of the two IPFC9 Bleeker Awards, Jeffrey M. Leis (Ecology) and Gerald R. Allen (Systematics) provided excellent talks on "Change in the early life-history of Indo-Pacific Fishes" and "The center of Indo-Pacific reef fish diversity". A total of 462 papers were presented, including 328 oral and 134 poster presentations. The main themes of IPFC9 included systematics, evolution, zoogeography and phylogeography, biodiversity, ecology, behavior, and conservation. There were 14 symposia, which included topics such as "Top predatory fish in the Indo-Pacific ecosystems", "Fish diversity across environmental extremes", "Ontogeny and systematics of Indo-Pacific fishes", and "Phylogenetics and diversification of the Percomorpha". IPFC10 will be held in Papeete, Tahiti.

  • In 2019, the U.S. Department of Defense and the U.S. Department of State issued two reports to announce their plan to fulfill "free and open Indo-Pacific". Two reports commonly insisted on the support and participation from allies and partners to maintain security and stability in the Indo-Pacific. In response to this, neighboring states in the Indo-Pacific, including Japan, Australia, India, ASEAN, and Taiwan have different perspectives and stances based on their national interests. South Korea, too, has not clearly announced its position because they need to consider the alliance between the U.S. and South Korea as well as relationships between South Korea and China. This report focuses on the stances of neighboring states to the Indo-Pacific strategy and expected pros and cons of the participation of the strategy. In addition, when considering the name of strategy, the Indo-Pacific, naval power will be a main instrument to implement the strategy. Thus, this study also investigates the role of naval power in the Indo-Pacific strategy.

  • The paper introduces US Indo-Pacific Strategy and discusses its meanings and implications for international security and our strategy. It tries to look at the Indo-Pacific strategy(IPS) through the lenses of international political theories. The paper provides three important observations. First, the US Indo-Pacific strategy is a declaration of the national identity of the US as an Indo-Pacific nation. The paper argues that the IPS reflects the US leadership that would facilitate the formation of, so called, the Indo-Pacific community. In arguing these points, the paper notes that the IPS has rich elements of constructivist approaches including norms and national identity. Second, the paper observes that the IPS report serves as an effective deterrent strategy. The IPS does not call out China as an enemy. But, it tries to deter against a range of actors including China by warning that whoever violates the rules-based order in the region would have consequences. Third, the paper maintains that the IPS is an effort by the US to mitigate the risk of a great power war between the US (an established power) and China (a challenging power) because the IPS articulates the United States's willingness to work with China as long as it plays by the rules. There will be challenges to the US and other countries in the region including South Korea particularly because of economic interdependence. However, the paper argues that the IPS stands for an optimistic sign of the future security in the Indo-Pacific region because it is a manifestation of the US for its national will to defend the status quo characterized as Pax Americana which has been maintained since the end of the Second World War. It also argues that South Korea also can, and should make the most of this opportunity by enhancing our capacity in national defense.

  • The paper tries to review the structure, functions and responsibilities of International Fisheries Bodies including the Indo-Pacific Fisheries Commission(IPFC), which was changed to Asia-Pacific Fisheries Commission(APFIC) by the amendments of the Agreement on 1993. In addition to this review it tries to find out the current issues of international fisheries in the Asia-Pacific m It also tries to find ways and means for our country to manage such kind of international fisheries issues in that area. Finally, it tries to propose ways how our country strengthen its activities in International Fisheries Bodies and impact on establishment of internationl fisheries policies.

  • One of the factors influencing the climate around Korea is the oceanic-atmospheric variability in the tropical region between the eastern Indian and the western Pacific Oceans. Lack of knowledge about the air-sea interaction in the tropical Indo-Pacific region continues to make it problematic forecasting the ocean climate in the East Asia. The 'Tropical Indo-Pacific water transport and ecosystem monitoring EXperiment (TIPEX)' is a program for monitoring the ocean circulation variability between Pacific and Indian Oceans and for improving the accuracy of future climate forecasting. The main goal of the TIPEX program is to quantify the climate and ocean circulation change between the Indian and the Pacific Oceans. The contents of the program are 1) to observe the mixing process of different water masses and water transport in the eastern Indian and the western Pacific, 2) to understand the large-scale oceanic-climatic variation including El Nino-Southern Oscillation (ENSO)/Warm Pool/Pacific Decadal Oscillation (PDO)/Indian Ocean Dipole (IOD), and 3) to monitor the biogeochemical processes, material flux, and biological changes due to the climate change. In order to effectively carry out the monitoring program, close international cooperation and the proper co-work sharing of tasks between China, Japan, Indonesia, and India as well as USA is required.

  • We obtained four zoeal stages of Harrovia japonica from laboratory-hatched material. They are described, illustrated in detail, and compared with those of other known species in the family Pilumnidae. The general zoeal morphology of H. japonica coincides well with those of other known species of the Eumedoninae (excluding Echinoecus pentagonus) and Pilumnus minutus of the Pilumninae. In order to facilitate the study of planktoncollected material, we provide a key for the identification of seven known zoeae of the Eumedoninae from the IndoPacific.

Occurrence of Indo-Pacific Bottlenose Dolphins Tursiops aduncus off Jeju Island, Korea during the Early 2000s (2000년대 초반 제주도 남방큰돌고래(Tursiops aduncus)의 분포 양상)

  • The Indo-Pacific bottlenose dolphin Tursiops aduncus commonly inhabits the coastal waters of Jeju Island, Korea. An investigation was conducted using data from vessel sightings and point sightings from land. During 40 days of vessel sighting surveys between 2007 and 2010, a total of 18 dolphin groups were encountered. The overall sighting rate was 0.01 group/n.m. Most Indo-Pacific bottlenose dolphins were sighted within 500 m of the northern coast of Jeju Island during surveys. Also, dolphin groups were observed 47 times during 109 days of shore-based surveys conducted between 2011 and 2015. The results of a dolphin distribution survey conducted in 2011 were generally similar to the results of previous surveys. However, there were no dolphin sightings from 2012 in Hanllim-eup, in the north-western part of the island, where dolphins were sighted frequently until 2011, whereas dolphin observations increased in the southern part of the island. The mean group size was 35.4 (SD=18.08) individuals. The most frequently sighted group size was 36-40 individuals. To conserve resident dolphins off Jeju Island, long term sighting surveys and environmental assessment are required to monitor their distribution patterns.

  • Haloptilus caribbeanensis Park, 1970 (Copepoda, Calanoida, Augaptilidae) is redescribed in detail on the basis of an adult female collected from Suruga Bay, Japan. This is the first record of the species from the Indo-Pacific region. Morphology of the Pacific specimen agrees well with that of the Caribbean Sea and Gulf of Mexico specimens, except for the numbers of mandibular teeth. The former has five teeth and the latter six teeth on mandible. The segmentation and segmental aesthetasc numbers of female antennules of H. caribbeanensis are compared with those of five species of Haloptilus (H. angusticeps, H. fons, H. longicomis, H. ornatus and H. spiniceps). These characters show morphological differentiation at the species level. H. caribbeanensis has no aesthetasc on the proximal segments II, IV, and VI of the female antennules.

  • 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'.
