Additional Information
Notes:
Information below comes from VanderLugt and Lenz (reference above).
These copepods have been successfully and exclusively used to get flame angelfish past metamorphosis.
The copepods move through 6 naupliar stages and 5 copepodite stages before their final molt into adulthood. Males do not feed, though they possess rudimentary, non-functional mouthparts. Females are broadcast spawners, casting eggs down to the substrate. Eggs hatch in less than 12 hours. (No diapause eggs.) The first two naupliar stages do not feed. Actively feeding naups show a colored digestive tract.
Stage (W, L)
Egg (58, )
N1 (39, )
N2 (47, 73)
N3 (53, 106)
Adult female (162, 403)
Naups reach N3 in just less than one day (and begin feeding). Copepods reach adulthood in 6 days.
Best food for Parvocalanus is a mixture of Isochrysis (T-Iso) and other microalgae, though the authors maintained the copepods with just T-Iso. Algae paste did not work for these authors as a culture medium. I do not have those live microalgae available so I will try with Oxyrrhis marina fed a diet of algal pastes. See my O. marina culture journal: http://www.marinecolorado.org/forums/showthread.php?5334-Culture-journal-Oxyrrhis-marina Copepod starvation occurs quickly. B. similis (the other copepod in this study) starvation is at 24-48 hours.
Algagen says the lifespan is 12-15 days.
