Any Phytoplankton experts out there?

[gREEF stricken]

I am culturing Nannochloropsis. Anybody have any input on wether nanno can acclimated slowly to 100% freshwater??

Thanks

no, it cannot. It can be brought to pretty darn low salinities, but the nanno species most culture cannot be acclimated to 100% freshwater. There is at least one described species of freshwater nanno though, is it useful, dunno.

It pays to work in an office with a Phycologist with 5 post docs :lol:

The reason I ask is I am wanting to feed nanno to my Daphnia. If I culture it in VERY low salinity would it be a viable food source for a 1/2hr or so for gut loading??

I'd go with chlorella, which is like nanno, but freshwater. I'll ask which ones he'd suggest for gut loading your daphnia. I know we worked with some FW enrichment of daphnia

AWESOME. Thx very much for the help

you can most certainly turn sw nanno to fw nanno. both nannochloris and nannochloropsis are able to go back and forth. dunaliella and i think tetraselmis as well.
go for it.
what are you fertilizing with? i use 1 drop ferts to 100 mls culture. straight tap water with ferts for fresh water culture works.. try a small batch if you're not comfortable with it.

with the oncoming spring and longer days, outdoor cultivation is possible. free light is free light.
have fun with it. i used to use my converted nanno to top off my filter feeder display.

I use the stuff from FL Aqua farms. Have only used it for SW culture so far. Makes sense it would work for culture green FW as well. Where can I get a Chlorella starter culture? Raise it same procedure as Nanno??

Thx

i would assume. apparently most nanno cultures are contaminated with chlorella. not so sure, i've yet to put my nanno under the scope. you're using the same ferts i am. did you get your nanno from faf?

No, I bought it from an eBay vendor.

Hey Gresh, will I get regular old Euglena in freshwater using same micro algae? Same as I do when drop yard trimmings in a bucket for a week or two and get "green water?"

I'll take the word over someone that is highly educated on the subject, and grows it commercially Sorry

sorry gresh, i took the advice from florida aqua farms plankton culture manual... tetraselmis page 15,page 16 for nannochloris and dunaliella and page 18 for nannochloropsis.... that was a couple of years ago and i've been playing with it ever since. give it a try.... i can give you some microscope shots of my freshwater nanno i converted this week for top ups if you like... it's doing very well.

more educated? you're hilarious...you should try a microscope and some experimentation.... that's what education is. because science is mostly observation.
or you could just take someone else' word for it... i don't care.
