Development, growth, and egg production of Centropages abdominalis in the eastern subarctic Pacific
Centropages abdominalis is a neritic, omnivorous, temporally abundant copepod present throughout the subarctic Pacific and its marginal seas. The two main objectives of this study were to determine how temperature influences the development of C. abdominalis and whether growth rates of in situ popul...

Centropages abdominalis is a neritic, omnivorous, temporally abundant copepod present throughout the subarctic Pacific and its marginal seas.

At 6.9°C median development time from eggs laid to 50% adults was 42 days and the average weight-specific somatic growth rate was 0.17 d-1.
