  • Abstract To understand the epibenthic invertebrate community on the contential
    shelf break of southwestern Taiwan, we had sampled along the shelf break from
    Yongan to southern Penghu with beam trawl. Sampling was more intensively
    around nature gas drill site planed by China Petroleum Corporation. Dominant
    species were Cnidaria and Arthropoda in this area. The distribution of
    dominant species was different from inshore to offshore. The composition of
    dominant species group of offshore area were more homogeneous than that of
    inshore area. The abundance of Cnidaria was positively correlated to the
    number of species, abundance, diversity, and richness of the sampling site.
    Cnidaria appeared mostly on offshore, which including Bellonella sp.,
    Epizoanthus ramosus, Actiniaria sp., Tropidocyathus lessonii, Flabellum
    distinctum and Flabellum sp.. Furthermore, Parapagurus Diogenes, Actumnus
    sp. and Polychae sp.2 showed high co-occurrence with Cnidaria in spatial
    distribution. Results of multivariate analysis showed heterogeneity in
    community structure among inshore and offshore. Community composition of
    offshore can be seperated into 3 subgroups, which were western Penghu
    Channel, eastern Penghu Channel, and area around nature gas drill. These
    findings revealed a significant influence of environment condition and
    topography on the composition of benthic community. The dominant species of
    inshore area were Portunus spp. and Parapenaeopsis spp.. The dominant
    species of western Penghu Channel were Portunus spp., Metapenaeopsis spp.,
    Sepia sp., and Philine sp.. The dominant species of eastern Penghu Channel
    were Flabellum spp., T. lessonii, Alcyonacea spp., and E. ramosus. The
    dominant species of area around nature gas drill were E. ramosus, Actiniaria
    sp., T. lessonii, and Parapagurus Diogenes.
