% : in % of body length.

Issued from : C.B. Miller in Biological Oceanography 2004/2005, Blackwell Publishing. [p.157, Table 7.1]. From Petipa, 1967.
Calanus helgolandicus (= Calanus euxinus) dominant zooplankters in the Black Sea. Data characterize the season of peak production. Mostly taken from Landry (1978): 28 mgC m^-2 day^-1.
Miller underlines the difficulties of the production estimations for single species, and virtually none for whole systems, but we would like to know how much food the oceans produces for animals we harvest like herring, anchovy, cod, and pollack. See Huntley & Lopez, 1992: model); Kleppel, Davis & Carter, 1996; Huntley, 1996; Hirst & Sheader, 1997; Hirst & Lampitt, 1998; Vidal, 1980.

Rem.:

After Unal & al. (2003, p.157, In : 3 rd International Zooplankton Production Symposium, 20-23 May, Gijon, Spain) the morphological and genetical differences are very weak between this species and Calanus helgolandicus.
For Isinibilir & al. (2009, p.403) the small-sized males and females in the Marmara Sea are actually not C. helgolandicus but Black Sea C. euxinus after accelerated development in an environment with higher temperature and salinity.
After Svetlichny & al. (2010, p.128) in the Marmara Sea, C. euxinus migrating vertically will experience prinounced salinity changes from 18 to 38.5 psu. Therefore, C. euxinus either adapted to living in a salinity gradient or is confined within a narrow brackish subsurface layer.
After Vucetic (1965) the number of teeth on coxopodite is for the females 24-26 (23-35), and 16-20 for males, and in C. helgolandicus var. ponticus (Yashnov, 1955) (= Calanus euxinus 24-29 (18-37) for females, and 11-21 for males.
