Nothing wrong with resurrecting old threads - great way to breath new life into a topic. I"m curious too.

I tried them with several starters of P. crassirostris from Reed. The adults seemed to do fine with the ciliate as a food source and certainly kept reproducing but the cultures slowly died off over roughly six weeks or so. My guess is that O. marina is too large to serve as a first food for the tiny baby copepods. I think that your cultures could do fine with a mixture of T-Iso and O. marina, but if you have to go through the trouble of culturing T-Iso in the first place then why bother with the mixture? Of course, using a mixture might mean that you could get by with less T-Iso and that might be a good thing.

My thoughts exactly. It's the culturing of the Iso I'm looking to avoid (don't judge me!) I almost tempted to purchase a starter just to see if I can get the naups through the early stages just long enough to be large enough to take O marina. A tonsa is the other species I want to try O marina with.

It's easier to culture phytoplankton than you think. I mess with my cultures once a week, and I have plenty to keep 5 different copepods going and some of my rotifers as well. It's easier to grow the phyto, than it is to keep cultures of O. marina, and the pods do so well, in my opinion.

It's not the trouble it's the space

In all my tries with T-Iso, I've managed one split of one bottle total. Heck, just the cleaning alone. I kept O. marina for years in open-topped buckets. Joe, the problem is that the copepods are going to have naups constantly, so you will have to constantly supplement O. marina if you want to keep the culture going.

Andy, you should try again. I find that there is some acclimation period where there is a pause in growth before it really does well.

Actually was pretty successful with T Iso. I'm confident I'm able to culture phyto if needed I just honestly don't have the space for a culture station like I used to. I know everyone says that but if I give up the space I have for larvae I may as well not culture the copepods anyway lol The O marina can be cultured in the space I currently have my rotifers, which I don't want to culture anymore anyway. That frees up enough space for something like A tonsa and doesn't encroach on my larval space.

I really should, Kathy. Thinking back on it, I think the only success I had was in the summer batch. I do wonder if I gave them too cold of an environment growing in the basement. The first thing I would try differently would be a warm water bath around the bags.
