The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries.

E-mail: [email protected] 2 Conservation International Indonesia Marine Program. Jl. Dr. Muwardi No. 17, Renon, Denpasar 80235 Indonesia. Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region. Introduction and finally a complex geologic past highlighted The region consisting of eastern Indonesia, East by shifting island arcs, oceanic plate collisions, Timor, Sabah, Philippines, Papua New Guinea, and widely fluctuating sea levels (Polhemus and the Solomon Islands is the global centre of 2007). reef fish diversity (Allen 2008).

Address correspondence to W. L. Smith at the address above, or e-mail: [email protected]. Abstract Knowledge of evolutionary relationships or phylogeny allows for effective predictions about the unstudied characteristics of species. These include the presence and biological activity of an organism’s venoms. To date, most venom bioprospecting has focused on snakes, resulting in six stroke and cancer treatment drugs that are nearing U.S. Food and Drug Administration review. Fishes, however, with thousands of venoms, represent an untapped resource of natural products. The first step in- volved in the efficient bioprospecting of these compounds is a phylogeny of venomous fishes. Here, we show the results of such an analysis and provide the first explicit suborder-level phylogeny for spiny-rayed fishes. The results, based on ;1.1 million aligned base pairs, suggest that, in contrast to previous estimates of 200 venomous fishes, .1,200 fishes in 12 clades should be presumed venomous.

Chan Larval descriptions of tropical marine and coastal fishes are very few, and this taxonomic problem is further exacerbated by the high diversity of fish species in these waters. Nonetheless, accurate larval identification in ecological and early life history studies of larval fishes is crucial for fishery management and habitat protection. The present study aimed to evaluate the usefulness of DNA barcodes to support larval fish identification since conventional dichotomous keys based on morphological traits are not efficient due to the lack of larval traits and the rapid morphological changes during ontogeny. Our molecular analysis uncovered a total of 48 taxa (21 families) from the larval samples collected from the Klang Strait waters encompassing both spawning and nursery grounds of marine and estuarine fishes.

  • Species Composition and Diversity of Fishes in the South China Sea, Area I: Gulf of Thailand and East Coast of Peninsular Malaysia
    S4/FB3<CHAVALIT> Species composition and Diversity of Fishes in the South China Sea, Area I: Gulf of Thailand and East Coast of Peninsular Malaysia Chavalit Vidthayanon Department of Fisheries, Bangkok 10900, Thailand ABSTRACT The collaborative research on species composition and diversity of fishes in the Gulf of Thai- land and eastern Malay Peninsula was carried out by R. V. Pramong 4 in Thai waters and K.K. Manchong, K.K. Mersuji in Malaysian waters, through otter-board trawling surveys. Taxonomic surveys also done for commercial fishes in the markets of some localities. Totally 300 species from 18 orders and 89 families were obtained. Their diversity are drastically declined, compare to the previous survey from 380 species trawled. The station point of off Ko Chang, eastern Gulf of Thai- land and off Pahang River shown significantly high diversity of fishes57 and 73 species found. De- mersal species form the main composition of the catchs. The lizardfish Saurida undosquamis, S. miropectoralis, the bigeye Priacanthus tayenus and P. macracanthus, the rabbitfish Siganus canaliculatus and hairtail Trichiurus lepturus were the most abundant economic species found in mast of the sampling stations. Fishing efforts were 34 hours and 49 hours for the cruises I and II, with average catch per hour of 12.04 and 34.79 kg. respectively. The maximum catch per hour was 175.3 kg in Malaysian waters, the minimum was 4.33 kg in Thai waters. The average percentage of eco- nomic fishes is higher than that of trash fishes in Malaysian waters, it ranged from 55.45 to 81.92 %.

    Bull. Mus. natn. Hist, nat., Paris, 4e sér., 6, 1984, section A, n° 2 : 453-485. Les genres et sous-genres de Chaetodontidés étudiés par une méthode d'analyse numérique par André MAUGÉ et Roland BAUCHOT Résumé. — L'analyse en composantes principales des cent quinze espèces de Chaetodontidae à l'aide de trente variables (neuf valeurs méristiques, treize proportions de diverses parties du corps et huit caractères morphologiques) a permis de préciser, à partir de divers dendrogrammes, les affinités de ces espèces entre elles et de proposer une nouvelle répartition des Chaetodontidae en vingt genres, dont quatre nouveaux, et vingt et un sous-genres, dont six nouveaux. Abstract. — Principal component analysis of the 115 species of Chaetodontids using 30 varia- bles (9 meristic data, 13 proportions of different body parts and 8 morphological characters) allowed us to define, from the study of different dendrograms, the affinities of the species and to propose a new classification of the Chaetodontids in 20 genera (4 of which are new) and 21 sub-genera (6 of which are new).
