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.

Miller note that development time in the laboratory as function of temperature is an approximation because the laboratory rate applied to predict stage duration from the temperature is not inhibited even partially by low food levels, but usually for inshore habitats it seems justified.

Relationship of daily estimates of production to biomass ratio (P=/B) for Acartia clausi in Onagawa Bay (Japan) to temperature.
Miller note that over the 1.5 year study, the lowest productivity was 0.0374 mgC m-3 day-1. Some of that comes from stock variation, some from growth rate variation (vs. temperature). Total annual production was 163 mgC m-3 yr-1, or about 2.5 gC m2 yr-1.
In a nearshore embayment like this the primary production is very likely of the order of 500 gC m-2 yr-1. If we assume that the gross growth efficiency of these copepods is about 20% (a low-sde estimate), then they use about 12/500 or 3% of the primary production.

Acartia clausi from Wyville Thomson Ridge (60°03.4' N, 07°03.9' W to 60°08' N, 07°02.9' W) on 24 April 1978: Vertical distribution of this group 1 contained 3 species which are all commonly recorded, surface-living organisms of the North Atlantic and Norwegian Sea. The most abundant was Acartia clausi (82.8% of the animals in the group); it occurred between the surface and 160 m with its highest numbers in the upper 10 m of the water column. Other species: Paracalanus parvus, and Evadne nordmanni (Cladocera).
A computed coefficient of dissimilarity was used in association with a 'group-average' clustering strategy (see Clifford & Stephenson, 1975) to classify the plankton taxa on the basis of their vertical distribution after the indices of similarity and the results arranged diagramatically in the form of a dendogram (Fig.2). Classification was carried out using the Bray-Curtis measure which gives a coefficient of dissimilarity.

Rem.: Littoral, neritic. 0-160 m (Pipe & Coombs, 1980, Arctic: 60°N, 07°E).
Rare in the open sea and mesopelagic (in Roe, 1984), sometimes bathypelagic (Farran, 1926). For Acha & al. (2020) this species is observed mainly on the coastal in front of Rio de La Plata (Argentina).
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 Korea 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. For E.G. Durbin & al. (1992, p.343) A. hudsonica corresponds to A. clausi in earlier studies from New England coastal waters (cf. Conover, 1956; Deevey, 1960; Durbin & Durbin, 1981).
After Christou a Verriopoulos (1993) the development of A. clausi in Saronikos Gulf (E Mediterranean Sea) is not 'isochronal'.
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.

After C. Razouls (unpublished) observed in one occasion directly on the rocky shore of Banyuls, at mid-day by full sun light in surface layer (irregular swarm of several meters of red color).

Zaika (1968) in the Black Sea, finds a daily ratio P/B = .04 d-1 and an annual P/B yr-1 = 16. Greze & al. (1968), nearshore in the Black Sea, find a daily ratio P/B = .09 d-1 and an annual P/B yr-1 = 32.
Landry (1968), in the coastal lagoon Washington (8-20°C), finds a daily ratio P/B = 012-0.23 d-1 and an annual P/B yr-1 = 57 (calculated from author data by Burkill & Kendall, 1982).
Production :
After Vieira & al., (2003) from Mondego estuary (Portugal): 63.44 mgC per m3 per year. P/B = 25.50.
After observed and calculated developmental time in weeks: 8.0, 8.30 at 62°.00 and 6.0 , 5.40 at 50°15', respectively.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 4 corresponding to small filter feeding herbivorous and mixed feeding omnivorous (mostly broadcasters).
Often confounded with Acartia (Acartiura) omorii in the japanese waters.
The feeding mode after Barton & al. (2013, Table 1) is a mixing between 'ambush' and 'feeding current' (hovering) (See definition in Rem. Centropages typicus.
