Carte 3 Issued from : K. Kimoto, S.-i. Uye & T. Onbé in Bull. Plankton Soc. Jpn, 1996, 33 (2). [p.136, Fig.1].
Schematic illustration of the oogenesis of Sinocalanus tenellus from brackish-water pond in Fukuyama and laboratory-reared between January and March 1983.
a, with ''immature'' oocytes in the oviducts; b, with ''developing'' oocytes in the oviducts; c, with ''mature'' oocytes in the oviducts; d, dorsal view of c; e, during spawning.
ov.: ovary; ovd. oviducts; sp.: spermatophore; i.o.: ''immature'' oocyte; d.o.: ''developing'' oocyte; m.o.: ''mature'' oocyte.

Nota: One female was capable of producing more than 2531 eggs during 70 days after molting to adult. At high food concentrations, the egg production rate became maximal around 20°C at 60 eggs/female/day or 0.37 by day in terms of carbon weight-specific rate.

Effect of food abundance on the daily egg production of Sinocalanus tenellus laboratory-reared at 20.5°C.
Vertical lines: ±S/D. The curve is eyefitted one.
Food: Isochrisis galbana (ca.5x10 power 4 cells per ml) and Thalassiosira weissflogii (ca. 5 x 10 power 3 cells per ml).
