Female (adult from Sagami Bay): Fig.1 (above); B, posterior urosomal somites and caudal rami (dorsal), showing inner and outer glands, granules in inner gland (gr) and discharged granules (dgr); D, anal segment and caudal rami (ventral), showing pores of inner gland (black arrows) and outer gland (white arrows). Fig. (below): abdominal somites and caudal rami (lateral), showing granules in inner gland and discharged granules (dgr). Lines indicate locations of cross-section for histological analysis (see in publication fig.3). Light microscopy in Fig.1 B; Scanning electron microscopy photograph in D and fig.2. Nota: The mechanical disturbance of the live specimens kept in seawater failled to excite luminescence from the copepods. No autofluorescence was observed from the caudal glands of live specimens under UV excitation. Alternative possible functions include secretion of defensive substances (predator avoidance) or substances that might enhance swarm formation and/or the possible functions of the glands for egg and sex pheromone. A survey of preserved copepod collections indicated presence of similar glands in others species in Calanus, Cosmocalanus, Mesocalanus and Nannocalanus genera.

 issued from : H. Toda & E. Hirose Scanning electron micrographs of two types of Calanus sinicus eggs.
E-G: egg A-type; F-H: egg B-type.
Nota: Egg A-type:(diameter: average 0.175 mm, range = 0.157-0.187, C/N ratio : 4.6). Egg B-type: diameter: 0.165 mm, range = 0.158-0.173, C/N ratio: 5.10.
Both types of eggs started to develop immediately after release, and hatched into nauplii within one day;
A-type eggs observed were similar to the eggs of Calanus from Tromsø reported by marshall & Orr (1955), whereas B-type eggs resembled those of calanus helgolandicus. The bulky blister observed in A-type eggs would correspond to the outer membrane mentioned in their book.. No intermediate form of eggs between these two types appear.

Monthly change in geographical distribution of copepodites and adults in Kii Channel and its neighboring waters (Inland Sea of Japan to the Pacific Ocean).
Nota: In the Inland Sea of Japan, this species is the second most important component following Paracalanus sp. in terms of biomass and production (see in Uye & al., 1986). The species occurred throughout the year in the study area. This means that the reproduction takes place continuously and the population is devoid of diapause in the seasonal life cycle. This species is regarded as one of the most important components of zooplankton in the shelf waters by virtue of its enormous abundance and large body size, and plays a significant role in the conversion of primary production into diet for carnivores, including fishes. |

Annual cycle of temperature (T °C), different classes of size of prosome of adult females (D), prosome mean lengths of adult females (Lg) at Xiamen Harbour during November 1979 to June 1980.
Nota: It is concuded from analysis of the age composition, adult sexual ratio and female cephalothorax lengths that there is three main breeding periods, i-e 3 generations in the harbour (Dec.-mid-Feb., end of Mar.-Apr. and Mid-May, respectively.
The first generation was reproduced by the immigrating population in the coastal current in winter, the 2nd generation was produced by the previous generation in spring and the 3rd generation's nauplii disappeared at the begining of June.
Water temperature (T) seems to be dominant factor affecting generation lengths and female cephalothorax lengths (Lg). A negative relationship was found between T & Lg. Lg = - 0.0666 T + 3.3718 with r = - 0.8764. |

Depth ranges experienced during early life stages (from egg to nauplius; dotted line).
Nota: Yoshiki & al. (2006) previously examined the effects of hydrostatic pressure on the egg development time and hatching success of calanus sinicus. Although egg development time was not influenced by hydrostatic pressure, the egg hatching success rate decreased with increasing pressure. Unhatched eggs were still alive after being removed from the pressure chamber after exposure to elevated pressure, and they subsequently died without hatching even though nauplii had formed in the eggs. Also, even when eggs hatched under high-pressure conditions, most nauplii showed abnormalities (Yoshiki & al., 2006; 2008). |

Calanus sinicus. The gonad development stages (GS1-4C) of females at sampling stations E6 and P1.
GS4 represented mature gonads of females, subdivided into three new categories GS4A,
GS4B and GS4C.
Nota: Most females at station E6 were immature and more females at station P1 were mature, they shared similar expression patterns of the gene VgR. Similar to decapods, two phases of vitellogenesis occur in copepods (See in Arnaud & al., 1982; Niehoff, 2007; Tiu & al., 2008; Thongda & al., 2015; Tiu & al., 2008; Roth & Khalaila, 2012; Klinbunga & al., 2015). Thus, the up-regulation of VgR expression of females at station E6 could suggest preparation for gonad maturity.
Favorable food conditions could support the final maturity of females, whereas the limited food would suppress gonad developme,t (Zhang & al., 2007; Wang and al., 2009) |

Conclusion after Zhou & al. (p.560): << The physiological status of C5 stage and females of C. sinicus inside and outside the Yellow Sea Cold Water mass (16 August to 1 September 2013) in terms of their morphology, metabolic rate and gene expression patterns is shown for the first time.
A large oil sac, low metabolic rate, suppressed molting development and high expression of ferritin indicated that C5stage inside the Yellow Sea Cold water mass were in a quiescent stage, while females were not. During over-summering, C5stage up-regulated ferritin expression and down-regulated EcR to suppress development.
The stable environmental conditions inside the Yellow Sea Cild water Mass (i-e. low temperature and limited food supply) enabled the C5stage to remain quiescent. The C5stage near the edge of the Yellow Sea Cold Water Mass were in an intermediate state between quiescent and active. The elevated food conditions near the edge might trigger the arousal of the quiescent C5stage. These differences in the physiological processes and the associated gene expression patterns between quiescent and active copepods and their correlations with environmental factors provide a foundation for future studies of the dormancy of copepods >>. |
