copepod selection : im ready to order some starts but need a second opinion - Monday, February 20, 2012 1:47 PM

i think i have the supplies i need to start working with some pods other than tigriopus .
i have a dense culture of O. marina and a stock pile of rotigrow plus .
all the sieves , aeration, culture vessels and heaters i believe i will need .
i do not have the space nor inclination to culture live algae so the species i choose must thrive on what i have or can obtain .
i would like to order 3 species of copepods . i would like 1 harp with palagic nauplii, 1 large calanoid and 1 smaller calanoid .
for the harp i was thinking tisbe and the large calanoid i was thinking the tangerines from algagen ( the genus and species doesnt come to mind at the moment . please remind me ).
as for the smaller calanoid i am not sure what would be a safe choice considering my resources .
it would be nice to order them all from one source (algagen) but parvocalanus seems tricky from what i have read and may not be an option with out live algae ( correct me if im wrong ).
so that leaves Acartia , pseudodiaptomus and apocyclops . (not sure where to get apocyclops)
whats a boy to do?
i need somthing easy-ish with the capacity for dense cultures .
i am hoping you lovely people can help me weigh out the pros and cons of culturing these species to help me come to a safer conclusion.
thanks All,
Aron

The "Tangerines" are Arctodiaptomus salinus.
 
Since nobody is selling Apocyclops commercially, you will have to source it from another hobbyist.  PM me.

thanks jim .
is Arctodiaptomus salinus a possibility on O. marina and rotigrow?
do you think i will be better off with apocyclops over acartia while using rotigrow plus and o. marina?

Not sure about the Arctodiaptomus and Oxyrrhis, but it is a distinct possibility, since the Arctodiaptomus were a hitchhiker in some Moina salina.
 
I'm not sure how well Acartia will do with O. marina, but Apocyclops are proven to grow well when fed O. marina.

Both A.salinus and A.panamensis can be raised on pastes,hardly Acartia.
Harps with pelagic naups are unlikely.

Euterpina is a pelagic harpacticoid.
 
Luis, you must be getting old (much like I am)!  Did you forget that you posted on another breeding site the following?

I am getting old,but I remember well what I said,so far
These are exceptions and our friend here is asking for advise.He needs easy copepods and the ones I mentioned can be raised on pastes,without even the need of O.marina.

i found a paper on the predation of Arctodiaptomus salinus on 3 rotifer species .
terry snell was credited . i found the paper browsing google on my smart phone but couldnt post a link.
the paper states the adult stages will feed on L strain and s strain rots but s strain were accepted more readily . 
i wonder if the smaller life stages will take O. marina?
looking good so far . 
now to find a good protocol for dense tisbe culture

Thankfully you are wrong, or at least with the one we have been working with, which came from the same source as Algagens.  We've achieved ~40/ml now on paste.  Doesn't sound like a lot, but when you consider the big guys are growing them at a couple per ML, the achievement does sound better (and this is at scale, not in some beaker).  Beyond that I cannot comment as we are still working with them.

40/ml sounds very impressive to me! 
 
I'd be extremely interested to know any additional tiny tidbits you might be able to share about the paste protocol for Parvocalanus, if and/or when you are able!

too bad you can't comment.  We would love to know how you get 40 per ml.

Gresham, you guys need Apocyclops!

Don't think I haven't offered it to them!
