- •
Calanus marshallae egg production rates (EPRs) were highest in spring and winter.
- •
EPRs were high in winter and spring when ciliates were abundant.
- •
Some diatom blooms in summer resulted in high EPRs; others produced low EPRs.
- •
Diatom species richness in summer had a positive effect on high EPR.
- •
During some mono-specific blooms, EPRs were depressed.
