    Does anyone have experience with ZM’s Spirulina supplement for feeding live Daphnia? Failing that, any suggestions for proprietary products?

    This is for the SEI project and we have several pools, each with a diameter of 3 metres for live food production this year.

    TA Aquaculture’s spirulina product is cheaper. I’ve not used it for Daphnia but do use it for marine copepods.

    What’s the volume of the pools? You might do better growing live algae in the ponds first, that would be the best choice, in my opinion.

    I use spirulina for Xenopus tadpoles and Artemia – have been using the New Era stuff and getting good results.

    It’s very scientific – when the water isn’t green anymore I add more spirulina

    Hi Matt, i should imagine that the costs would soon mount up using commercial spirulina for feeding daphnia..

    I have excellent results in the spring/summer using small amounts of manures.. Horse manure in a mesh bag would do the trick, i also use chicken manure pellets designed for Garden use, clean, easy to use and last a long time..

    I run two 200litre pools of daphnia and by rotation in summer i can culture enough food to feed 75 tanks several times per week.

    I used sheep droppings. Kept the last culture going for 3 years before the hard frost last winter shattered the old tank I was using. Just make sure it gets plenty of indirect sunlight.

    Thanks lads, and that’s very interesting about the use of, well, poo. Are we talking fresh or dried?

    rabbit droppings should be fine too then? That used to be used as an aquarium plant fertiliser by just pushing the pellets down into the substrate next to the roots

    There are horses grazing part of the delta and we actually had to install an electric fence around the last natural habitat of Aphanius to keep them from cr*pping in the water so we should be able to do this I think…

    Ste, got it, thanks a lot!

    No mate, i never bothered buying that one.. I use the O’masters book and its a excellent source of info..

    Matt, no problem, i hope its helpful to the cause…

    Heres my small setup, theres another 200litre tank behind the poly boxes..It will be tidied up before spring

    These are the Chicken manure pellets i use.. They dont smell too clever but are great for the job, clean, easy to use and fairly cheap..

    Do you not cover the tank Ste? I had to as water beetles would unerringly find a great place to set up home.

    Matt at my farm we culture Daphnia in 10’X10’X3′ ponds which are lined with HDPE plastic sheets. We add about 20Kg of fresh chicken manure to this and fill in water. The water will turn green in 2-4 days and then you can add your starter culture. When the plankton levels/Green water gets transparent i.e. visibility of more than 30cm we add about 26Ltrs note not Kgs of Chicken manure. We get enough from 4 such pits to feed about 20000 livebearers of different sizes twice a day and good amounts. You should also get Bloodworms in this if you keep the water level lower about 8inch.

    If the water gets too green and gets a crystal like surface add a few floating plants which will suck the excess right out and then can be used as shelter for your livebearers.

    Cheers Nik, looks like some form of poo is the way forward!
