Copepod Egg Production Rates from CCE Process Cruises, 2011-2019 (ongoing).

Egg production rates were determined on CCE process cruises for three species of copepod: Calanus pacificus, Metridia pacifica, and Eucalanus californicus. Copepods were collected by bongo net and adult females were promptly sorted into individual Petri dishes. Dishes were checked for eggs every 12 hours for a period of 24 hours for C. pacificus and M. pacifica, and 72 hours for E. californicus. Egg production rates are expressed as eggs per female per day. Eggs were incubated for an additional 36 hours for assessment of hatching success. The prosome length of the adult females was measured by ocular micrometer. Egg production rates can be used as a metric of secondary production.
