“…Copepods are the most predominant constituent among the zooplankton, and the characteristic of the plankton community in the sea area can be indicated by the composition of dominant copepods. Furthermore, there is close interrelationship between the distribution of plankton communities and the environmental conditions (YAMAZI, 1956;HIROTA, 1961). In the following, the interrelation between the distribution of the dominant copepods and the characteristics of water masses, in the sea area extending across the central part of the Setonaikai from south to north (Fig.…”

In the investigations at the three stations in Hiuchi-nada, twenty-one species of copepods were identified. The period of occurrence of every species was, in the main, similar to that recorded in my previous work in Bingo-nada situated in the northern outside of Hiuchinada. Among them, Paracalanus parvus, Oithona similis, Oithona nana, Corycaeus affinis, Corycaeus andrewsi and Microsetella norvegica occurred dominantly or subdominantly. From the results of the present survey and my previous work in Bingo-nada, the biological characteristic of the sea area extending across the central part of the Setonaikai from south to north is considered as follows. In the northern part of Bingo-nada area, the water mass is mingled violently with the polluted water caused by the sewage of factories and cities, and so Acartia clausi and Oithona nana are dominant. On the contrary, in the central part of Hiuchi-nada area where Oithona similis occurred dominantly, such effect of the polluted water seems to be the weakest.

“…In many inlet waters along Japan, these 2 species cooccur. Generally, 0. davjsae is much more abundant than 0. similis, particularly in the inner part of inlets during summer and fall, and the latter is distributed mainly in the outer part of inlets during winter and spring (Yamazi 1956, Ueda 1991.…”

We investigated the seasonal variations in biomass, somatic growth rate and productlon rate of the small cyclopoid copepod Oithona davisae in Fukuyama Harbor, a eutrophic inlet of the Inland Sea of Japan. The carbon biomass of the population, excluding nauplii, was lowest in early spring and increased exponentially in early summer to a maximum of 92.2 mg m-%n mid-June. Thereafter, it was relatively high, except for a mid-summer decline, until fall. The speclfic growth rates of naupliar and copepodite stages were estimated from their body weight increments and stage durations, assuming that In this highly eutrophic inlet growth IS food-satiated for this species. They increased exponentially with increasing temperature, ranging from 0.088 to 0.357 d-' for nauplii and from 0.060 to 0.446 d-' for copepodites within the annual temperature range of 8.9 to 28.ZDC. The production rate as a sum of somatic growth rate of copepodltes and egg production rate of adult females varied sirnlarly to, but showed a wlder range than, the biomass vanation. Annual integrated carbon productlon was 650 rng m-3 yr-l, or 4.88 g m-2 yr-'. 94 % of which was attained between June and October. Of the production, copepodite somatic growth and female egg production comprised 75 and 25 %, respectively. 0. davisae contributed 26% of the annual copepod community production in Fukuyama Harbor.

“…In Japanese embaymental waters north of Kyushu, Acartia clausi, Paracalanus parvus and Oithona aruensis are among the most abundant pelagic copeods (Yamazi, 1956;Hirota & Hara, 1975;Itoh & Iizuka, 1979;Ueda, 1980, etc.). In Kabira Bay, however, only 0. aruensis of these three species occurred in significant numbers; the other two species were not collected in the present study, except for a single specimen which resembles P. "parvus (P.…”

Taxonomy and distribution of the pelagic copepods were investigated in Kabira Bay, Ishigaki Island. From the samples collected by vertical and oblique tows, 13 species of calanoids, eight species of cyclopoids and one species of harpacticoid were identified. A new species, Pseudodiaptomus ishigakiensis, and other little known species are described. Acartia bispinosa, A. fossae and Oithona dissimilis are firstly recorded in Japan. Distribution of the major copepod species shows that the hydrographic condition of the inner part of the bay is appropriate for the maintenance of neritic species, and oceanic species presumably cannot proliferate in the inner part of the bay.
