Centropages abdominalis (from Fukuyama Harbor, Inland Sea, Japan). Seasonal variation in nauplii stage-specific abundance.
Nota: Sampling in a temperate eutrophic inlet. This area receives nutrient-rich water from a near by sewage plant, which provides secondary treatment to waste water. Red-tides and anoxic conditions at the bottom often occur in summer.
Samplings at intervals of 3 to 5 days from November 1986 to 8 November 1987. Zooplankton taken by oblique hauls by plankton net (62 µm mesh aperture) from bottom (depth 7 to 8 m) to the surface.
C. abdominalis were staged, sexed and counted, but as a congeneric species C. tenuiremis was also present, the separation between these species was made following the morphological descriptions of their developmental stages by Koga (1960) and Li & Fan (1990). |

Seasonal variations in total (nauplii + copepodites + adults abundances of Centropages abdominalis (filled circles) and Centropages tenuiremis (open circles) in Fukuyama Harbor (Inland Sea of Japan) from 7 November 1986 to 8 November 1987.
Within the thermal range between the two species (See remarks in Fig.14), the density and age structure of the C. abdominalis population are explained by temporal variations in the balance between fecundity and mortality.
The fecundity varied from 39 to 142 eggs/female/day, and the weight-specific egg production rate was positively correlated to both temperature and chlorophyll a concentration.
The population egg production rate depended largely of the density of adult females, and it was highest in February and March (see in Fig.9).
The fraction surviving from egg to Nauplius II was extremely low and variable (see in Fig. 10). In Generation G2, although the population egg production rate was lowest(, the fraction surviving to NII was highest (i.e. 4.0%) In G5, it was vice versa, and only 0.02% of the eggs spawned survived to NII. Landry (1978) reported that about 80% of the eggs never survived to NII for Acartia clausi in a temperate lagoon in Washington State (USA), and Uye (1982) found that mortality of 80 to 90% occurred from egg to NIII for Acartia omorii in Onagawa Bay (Japan).
Liang & al. (1994) assessed the loss of eggs by comparing incubation fecundity and egg-ratio fecundity of C. abdomionalis: 37 to 99% (mean: 87.5%) of the spawned eggs were lost during egg stage within the water column.
Hence, mortality in early life is probably concentrated in the egg stage. A significant part of the loss might be attributed to predation, including cannibalism, in addition to loss by sinking (see in Liang & al., 1994).True carnivores such fish larvae, chetognaths, medusae and ctenophores were absent or extremely rare in the Fukuyama's site during February-May while adults and late copepodites (CIV-CV) of C. abdominalis and Acartia omorii (both omnivorous) occurred (as many as 39 000 ind/m3) during this period. Assuming the clearance rate of each individual is 50 ml/ind./day), 1 to 86% of the water column was estimated to be cleared by day, thus the main source of mortality (by cannibalism) impacts the young stages (see in Hada & Uye, 1991 for Sinocalanus tenellus in a brackish-water pond of Fukuyama). Several species of diatoms inhibited copepod embryonic development causing higher egg mortality. The cell diameter of diatoms may play also on the possibility of capture by nauplii (See in Ianora & Poulet, 1993 and Poulet & al., 1994) |

Relationship between abundance and temperature for Centropages abdominalis (filled circles) and Centropages tenuiremis (open circles).
Nota: A clear pattern of alternation in the site was evident for C. abdominalis and C. tenuiremis. The abundance of both species and temperature were linked.: C. abdominalis appeared in the site when temperature was below 21.1 °C, and its density was higher at temperature below 10°C. On the contrary C. ternuiremis appeared when temperature was higher than 14.5°C, and became abundant at temperatures above 21°C. Replacement seems to occur within a temperature range between 14.5 and 21.1°C.
During an unfavorable temperature period, either species can exist as resting eggs on the sea-bottom (see Kasahara & al., 1974, 1975).
Temperature is the prime determinant of their occurrence in the Fukuyama's plankton. |

Centropages abdominalis (from Fukuyama Harbor, Japan). Relationship between water temperature and development time from egg-laying to hatching, to CI and adult.
Continuous lines calculated from egg development times using equations '6) and (7). Open and filled circles denote minimum development time and median development time, respectively.
Equation 6 expressed by the Belehradek's function: DSnI = 159 (T + 3.18) exp. -1.38, assuming that the species follows the ''equiproportional'' rule of development (Corkett, 1984) as observed for Centropages typicus (Fryd & al., 1991), the time required from egg-layying to reach developmental Stage i (DSi, d) can be calculated from the embryonic duration by multiplication of a proportional constant (M) (Corkett & McLaren, 1970) i.e equation 7: DSi = M x DSnI.
The multipliers for successive stages were: 1.68 (NII), 3.10 (NIII), 4.10 (NIV), 5.00 (NV), 5.95 (NVI, 78.10 (CI), 8.40 (CII), 9.68 (CIII), 10.9 (CIV), 12.2 (CV), 13.4 (adult).
Thus, the times from egg-laying to CI and adult were expressed by:
DSCI = 1131 (T + 3.18)-1.58
and
DSCVI = 2123 (T + 3.18)-1.58 . |

Table 4 : Comparison of the instantaneous growth rate (g) at 10¨C among calanoid copepods occurring in the Inland Sea of Japan.
Nota: The development time among three Centropeges species (Table 3) were almost the same rate; at temperatures around 17°C it takes about 20 days for them to develop from egg to adult, although the development time of C. typicus is longer than taht other species (Smith & Lane (1987)
The instantaneous growth rate of C. abdominalis is similar toi that of the other Centropages species.
Fryd & al. (1991) found thet the growth rate is constant over the all developmental stages for C. hamatus and C. typicus. For C. abdominalis, however, the growth rate is higher in copepodites than in nauplii. Moreover, the growth rate of C. abdominalis is high compared to those of the other calanoid species occuring in the low temperature period in the Inland Sea (Table 4) |

Centropages abdominalis (from Fukuyama Harbor, Japan). Seasonal variation in A biomass and B production rate.
Nota: The biomass was less than 5 mgC/m3 until late January and became high in February and March.
The maximum biomass of 67.1 mgC/m3 was recorded on 11 March 1987.
The pattern of the seasonal variation in production rate was similar to that biomass.
The maximum production rate (12.4 mg C/m3/day) was also recorded on 11 Marcgh 1987.
Cumulative production between 7 November 1986 and 29 May 1987 was 355 mg C/m3 or 2.66 g C/m2.
The contribution of nauplii to the population production was minor (overall mean: 8.6%), and primarily owed to copepodites (57.8%) and adult females (33.6%) |

Nota:
The empirical relationship between the ratio of daily production rate to biomass (P/B) and temperature denotes that the ratio increased exponentially with increasing temperature.
