.Surface salinity of the investigation area varies around 25 p.1000 and the deep water slinity around 34 p.1000. There is a temperature stratification with surface water warmer than 10°C from May to October with maximum of 20°C in August. The coldest period is January to March with surface temperatures of 1-2°C. The deep water ranges between 5 and 10°C.
The hauls were horizontal at 2, 20, and 40 m.
Limits subjectively regarded as the optimum temperature range: 5-20°C. |

Seasonal distribution in percent of total organisms of adults and naupliiAcartia clausi from Long Island Sound ( U.S.A.) 1952-1953.
The number of generations was estimated from the distribution of nauplii and adults.
The nauplii of each generation are designated by Roman numerals and the corresponding adults in Arabic.
An estimate of 4 generations a year was obtained using data from 1953 (B) supplemented by the information recorded from 1952.
Nota: Adults noted about December 1, 1952 have been designated 0. Some of the offspring (I) of this primary breeding stock reached maturity in February and were designated 1. The precise designation of adults 1 is complicated by subsidiary peaks in December and January, but a second naupliar peak II was undoubredly produced by these adults.
Adults 2 matured in Aptil of both 1952 and 1953 and probably produced nauplii III, although a gap in the 1953 data makes the exact date of origin of this generation questionable. |

Stage-specific abundance of A. clausi from Jakle's Lagoon in 1973 and 1974.
Cohorts (I-XI are delimited by the alternate pattern of shading.
Nota: The population dynamics and production of A. clausi were studied in a small temperate lagoon (surface area of approximateky 25,600 m2, mean depth 2.4 m) located on the southern end of San Juan Island (Washington) situated north of Puget Sound. An approach which integrated laboratory and in situ experiments with time-series sampling of the field population.
The cycles of abundance were similar in the two years of study and were not affected by differences in the cycles of tidal inflow, temperature, and food availability even though the latter two factors appreciably affected growth, development, and fecundity rates. The abubdance cycle is controlled by an annually consistent pattern of copepodid and adult mortality believed to be due predation by the three-spined stickleback (dominant fish species in the lagoon).
Cannibalism and periodic tidal stimulation of hatching of accumulated eggs in the sediment help to regulate population abundance within seasonal limits. |

Rare in the open sea and mesopelagic (in Roe, 1984), sometimes bathypelagic (Farran, 1926).
According to Østvedt (1955) this species at Weather ship M (Norwegian Sea) made a similar seasonal appearance as Paracalanus parvus.
The forms reported for the Pacific need to be revised (see: Carillo, Miller & Wiebe, 1974 concerning A. hudsonica). According to these authors the atlantic and pacific forms are genetically different, because interbreeding, experimentally realised before, was not possible anymore. Bradford (1976) considers, like more authors, that the wide geographic distribution of A. clausi must mask the existence of distinct species (rejection of the hypothesis of varieties resulting from ecological conditions).
Confused in the NW Pacific and the Arctic seas with A. hudsonica (see: Bradford, 1976; Ueda, 1986); off Corea and Japan with A. omorii and A. hudsonica (Kang & Lee, 1990), with A. ensifera in New Zealand.
Sometimes confounded with other species, like A. margalefi in European brackish waters (the superficial morphological characters do not permit a distinction with A. clausi, if it is not the difference in length; the same goes for Acartia teclae.
Seregin & Piontkovski (1998) indicate for this species a salinity tolerance of 5 to 35 g/L.
Occurrence in the China seas confirmed by W. Zhang (comm. pers. 2006).
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 530, and for Schnack (1989) = 814.
Gaudy (1962, p.150) points to 6 generations by year in the Gulf of Marseille (NW Medditerranean Sea).
