You have previously noted cannibalism in some copepod species. I have several questions right off...
Is cannibalism common among Calanoid and Cyplopoid genera?
I am culturing Pseudodiaptomus, Parvocalinus and Oithona (Apocyplops?). Many others are attempting these organisms along with "Tangerine Pods" (= potential cannibalism). Can the same be said of those three?
In the Parvocalinus, I have noticed that there are few to no first instars in the afternoon/evening. They are present in the morning. Is it common for copepod eggs to hatch at night in normal culture?
Also, with the Parvocalius, I am noticing distinct zonation. I keep clean stock cultures in one and three gallon fish bowls with one flat side facing a vertical incubator flourescent (standard t5 bulb) at about
8 inches from the bulb. The young copepodid stages are as close to the light (when on) as possible. Reproductive adults are in an opposite corner, in slower but regular current. This corner is still well lit by refracted light but the lighting and current are deffinitely different. Nauplii still seem to be somewhat current swept. Is this sort of zonation common?
I guess that I really need to obtain some copepod references.
Thanks in advance.
