Culture Journal, Species: Moina salina - Monday, March 18, 2013 10:21 PM
Culturing Journal DataSheet
This first post should be updated regularly to include new information as events take place or changes are made to your system

General
Species:  Moina salina
Species description:  Cladoceran of the family Moinidae
Culture source (link if possible):  Angi in Germany
If algae, CCMP # (Optional):  N/A
http://ccmp.bigelow.edu/
Culture Establishment Date:  10/29/2010
Continuation Date:  1/28/2011

Culturing Vessel Details
Salinity:  Various.  Ranges from 1.026 to 1.010.
Temperature:    Various.  Ranges from 55 - 75 F
pH:  Not measured

Vessel description:  Various.  Ranges from 500 ml flasks to glass fishbowls to 5 gallon buckets to 40 gallon Brute containers.
Lighting description:  Typically, ambient phytoplankton station light.  In the greenhouse, ambient daylight.
Lighting cycle:  In the phyto station, 16H on / 8H off.  In the greenhouse, daily light cycle for 38 degrees N latitude, depending on time of year.
Aeration description:  Inside, relatively strong areation from a rigid airline.  In the greenhouse, none.

Methodologies
Split methodology: Harvest about 1/4 daily from vigorous indoor cultures, replace water removed with clean, new ASW of same salinity.

Culture medium description: 
Saltwater anywhere from 1/2 to full strength salinity, plus live phytoplankton, or sometimes preserved phytoplankton products, such as RGComplete.

Cell count:
Not counted.

Additional Information
(No Pictures or Videos in the Section Please)
Notes: 
These have been in continuous culture, either inside in intensive culture, or in the greenhouse, in a co-culture in larger containers with Tigriopus and Apocyclops, ever since I got them back in October 2010.  During the winter, the greenhouse cultures will reduce their numbers and fecundity significantly, but they never disappear entirely.


You will be required to provide photographic evidence and as much detail as possible about your project in this thread.
If your thread does not contain detailed enough photos  and information the MBI Council will not be able to approve your reports.

Here is the original shipping label from the order I received from Germany.  They were shipped on 26 October 2010, and arrived on 29 October 2010.

Jim, two and a half years is pretty amazing.  In your polyculture, have you noticed any of the three species becoming dominant?

Dave, the Tigriopus tend to be predominate in the co-culture, depending on many factors.  If it is cold, short days, and little food, then the Tigriopus will definitely be almost all that you find.  On the other hand, if it is warm, long days, and lots of food, the Moina can bloom nicely.
