Summary

1. Methods are described that make it possible to raise copepod larvae at low population densities with abundant food so that development proceeds at maximum temperature-determined rates.

2. Using these techniques, eggs from ten species of calanoid copepods from the Arctic to the tropics have been hatched, two species have been reared and a further two have been bred.

3. The development of eggs and larvae with food in excess is physiological and will vary with the physical parameters of the environment. Under these conditions it is argued that development of larval stages is the same multiple of development of eggs at any given temperature.

4.Bělehrádek's equation adapted to relate development time with temperature has been used to describe and predict the development times ofPseudocalanus minutus from egg to adult female.
