I think our last speaker said that the nanno strain of algae was the

I did not go to that meeting, but I believe the nutritive value the speaker was talking about is lipid content. In microalgae strains, the two most notable lipids are EPAs and DHAs. These fatty-acid chains are important in the normal development of fish and shrimp larva. In fish, EPAs are not easily converted to DHAs, so it is important the fish recieve DHAs in their diets. Nannochloropsis is very high in EPAs, but does not have any DHAs. Other species of microalgae contain both EPAs and DHAs (notably Pavlova and Isochrysis). Pavlova is very difficult to culture, so Isochrysis is a good choice for culture when DHAs are important. This is a motile golden-brown algae which is a good food source for some soft corals, shellfish, and shrimp. If you wish to grow food for hard corals, rotifers would be a better choice. Rotifers will eat phytoplankton of 1-10 microns in diameter (ie. nannochloropsis). In my opinion, nannochloropsis is fine in most cases unless you are producing rotifers for larval fish or shrimp. I do not know which species the "red phyto" is, but would assume it is also high in DHAs and is therefore more "nutritious".

Adam, how do you know this stuff? I'm amazed. You and Jon Finch should get together. Seriously, though - you didn't have to paraphrase that from a book or anything? Wow. Are HUFAs important, too?

DHA and EPA are two types of HUFAs (Highly Unsaturated Fatty Acids).
I have my degree in biology, but I used this website as well...

Ahzo! I see the picture now. Also, this is just a misc. random thought... but when my mom was visiting here, she has to have a thing called a TPN line to give her nutrition. Anyway, a lot of the things we give fish are the things that her TPN provides. She was amazed that we add things like magnesium & strontium and look for food with HUFAs, etc.

Her TPN (totoal parental nutrition) has "lipids" which we calll HUFAS!!!
And Mg+ and Ca+!!!!
Too bad we can't get a mix like TPN! But, that stuff costs $400
bucks a bag!!! Guess my fish don't really need that...
But, nothings too good for the fry! Maybe I'll sneak some home.....
But, starting the IV might be tricky...Have to stick it in it's head?

I've got a jug of Florida Aqua Farms fertilizer. You can have some if
you need some, or if you want to order some, let me know, 'cause
I've got a few wants from there. Not enough to actually order by
myself, but!
Check the beginning of this thread, too, 'cause I think Ryan has a
spare jug o' fertilizer.....

Yes, he does. He lives in Syracuse. I asked him about it, thinking I could probably use it. If jglover wants it, that's cool. Or I could share it. Whatever works.

Suzy,
AWP on a TPN is about $90.00-$120.00 Still pretty expensive to be feeding to your fry.

Geez! I'll bet the boss just told me that we won't get mad when we get our
piddly 3% raises!
Is that the 3 in 1, or the custom mix?
