Microscope image - Is this Copepods larvae?

[Deisler]

Could anyone confirm if this is copepod larvae? 100x under microscope.

All pictures I found online are all adult pods, which would look completely different to larvae I assume

Thanks a lot.

Those are rotifers.

Thanks, Jay. I am culturing copepods and found them in the same culture.

Do you know if this type of rotifers could affect copepod culture? My copepods have been growing fine for a few months.

I'm not sure. They are Brachionus plicatilis (or something very similar). They should not directly consume copepodites (copepod larva) but they will out compete them for food, and they multiply faster, so I suspect that you will grow lots of rotifers, but fewer copepods.
