Early development of Calanus glacialis and C. finmarchicus
Egg and nauplii development of co-existing populations of Calanus glacialis and C. finmarchicus from Disko Bay, western Greenland, were measured in the laboratory with and without addition of food. Egg hatching rate was measured at 5 temperatures from 0-10 °C and the fit to a Belěhrádek equation was...
