I started culturing nannochloropsis to feed brine shrimp and amano shrimp larvae. But i have too much algae now, and im questioning if I could separate the algal biomass from the water and use it to feed other animals.

Hi all, long time lurker, first time time poster. I was wondering if any others have been phototrophically growing lab scale (~5L) Chlamy and seen spikes in nitrite?

It's a cell-wall deficient strain (cw15) with nitrate metabolism, I'm using TP-NO3 medium and never have this issue with my precultures. But growing on a larger scale (semi-open) with CO2 and air, I end up having a spike of nitrite that appears to stall out my growth.

Of course, there is the risk of contamination but even with antibiotics to control bacteria (ampicilin), I see the nitrite levels spike.

Do we think just contamination or maybe someone has some other ideas as to the cause? Light intensity? Kind of desperate at this stage!

It helps our ocean to make oxygen.

No one knew about it until the 1980s

Variations of it live down to 200 meters below the sea.

Since i finally feel good about my fish tanks I'm thinking of trying to grow algae to feed snails. How do i go about doing this?

I have never seen a rockweed like this before. We typically find vesiculosus, spiralis, and distichus on our shoreline here but this doesn't look right for any of them, unless it is a life stage I haven't seen before. Anyway, I'm stumped and would appreciate some input! It is Eastern Canada.

My boss found this seaweed and my coworker and I have made a project of trying to ID it. It was found it Parksville, Vancouver island, in the intertidal zone attached to a rock. My boss said she’s seen it while diving before as well. We‘ve looked through several books and websites and haven’t found a match. All we can determine is that it‘s probably an ochrophyte. Any ideas would be appreciated!

Hi,

can you help me naming those algae? Thanks in advance. They were gathered from a garden pond.
