  • Abstract The principal objectives of this research are to investigate seasonal
    and spatial variabilities of species composition and numerical abundance
    of the copepods in relation to environment factors in the Kaohsiung
    Harbor and it’s adjacent coastal waters, and compared the carbon 、
    nitrogen and hydrogen contents of the animal.
    In all, 61 species of copepods belonging to 16 families were identified
    from the samples collected at six stations in the Kaohsiung Harbor. The
    mean numerical abundance of copepods was 5.3 ±4.8 ×10
    5
    inds/100m

    .
    The dominant and frequent species were Parvocalanus crassirostris,
    Oithona dissimilis, Oithona brevicornis, Acrocalanus spp. and immature
    copepods (copepodite and nauplius), amounting to 91% of the total
    copepods catch. Among them, P. crassirostris was the most abundant and
    frequent species (contributed to 30% of the total catch). The numerical
    abundance of copepods exhibited seasonal and tidal variations, with
    higher abundance in spring and winter and during the high tide. The
    species composition of the copepods in the harbor was different from that
    of the local coastal water, with higher abundance and species number in
    the latter.
    From the monthly collections at a fixed station north of Kaohsiung
    Harbor, 42 species of copepods were identified and the mean abundance
    of copepods was 3.3 ±3.6 ×10
    5
    inds/100m

    . The most dominant and
    frequent copepods was Parvocalanus. crassirostris, O. dissimilis, O.
    brevicornis, Acrocalanus spp., Euterpina acutifrons and immature
    copepods, contributing to 92% of the total numerical abundance of
    copepods. The abundance of copepods exhibited significant seasonal
    change at this station, with higher abundance in winter and summer and
    lower in spring.
    The carbon content and dry weight of copepod were not significantly
    different between harbor and coastal water, but copepod’s carbon content
    showed significant difference among body sizes. Copepod dry weight
    was significantly different among body sizes, but not seasons.
