Luke* Posted October 2, 2004 Report Share Posted October 2, 2004 Is the best way to get oxygen to them (with little fuss) to leave them outside in a bucket where the wind will constantly yet mildly diffuse oxygen into the water? These...things I have are quite round, but I guess they could be full on plant detritus as you say Alan, and the ones I have at home are very thin and clear due to lack of food.

fins Posted October 2, 2004 Report Share Posted October 2, 2004 Oxy-hemoglobin, i.e. that which has coordinatively bound oxygen, is red in colour and this gives the see-through body of daphnia a red pigmentation. Individuals of the same strain in oxygen-rich environments tend to be yellow or almost unpigmented. An example of a species that seems to exist with very little hemoglobin in comparison to other members of its genus, is Daphnia hyalina. It is usually found in the open water of lakes where dissolved oxygen is plentiful. The colour is also moderated by what food is predominating in the diet. Daphnia fed on green algae will be transparent-green in colour, while those feeding on bacteria will be salmon-pink.

Luke* Posted October 3, 2004 Report Share Posted October 3, 2004 Thanks for the info Fins, I see they say "salmon-pink", which is kinda vague, my "things" are quite orangy, but this would obviously reflect the muddy conditions they come from. I wonder how the first one gets there? It's just a muddy little puddle essentially that is large enough to not dry up in a couple of good days weather. I collected a whole heap more today and I have them in a bucket outside. It would be good if I had a microscope to get a closer look. How did you take that picture Caryl? It looks like it was taken under microscope. Quote Link to comment Share on other sites More sharing options...

kylefish02 Posted October 4, 2004 Report Share Posted October 4, 2004 hey i dont really reckon that it would be worth to ship daphnia as there will most probably be someone done thier with them or if not you can just get a colony from biosupplies Quote Link to comment Share on other sites More sharing options...
MGilchrist Posted October 7, 2004 Report Share Posted October 7, 2004 been talking to biosuppliers, $26.74 for a 4-5 litre bag of daphia delivered to north island and $32.18 to south island not sure how many daphnia you get in that. Quote Link to comment Share on other sites More sharing options...
fins Posted October 7, 2004 Report Share Posted October 7, 2004 I got one and they dont have that many daphnia for the price. They just take a few buckets of water from a goldfish farm. Quote Link to comment Share on other sites More sharing options...
Aqua Posted January 26, 2005 Report Share Posted January 26, 2005 I'm not sure if people are still interested but... About 7 years ago, my 6th Form biology teacher (egad I'm getting on! :lol:) dragged us all up Mt St John, and after rainy weather, there's usually a pond at the bottom of the crater, and it's TEEMING with life! I remember we took quite a lot of samples, and the majority of greeblies were Daphnia... I'm not sure if the pond is still there, as I haven't been up Mt St John in the daytime for a long time, last time I was up there was Guy Fawkes to watch the fireworks! (Awesome viewing, btw) Only thing I'd warn people about is to not use the rope swing there, if you slip and fall (like one of my classmates did) it's quite a distance down to the lava rocks.... *wince* Quote Link to comment Share on other sites More sharing options...

malawi_man Posted August 18, 2005 Report Share Posted August 18, 2005 tanksman how much $$ was the daphnia for how much daphnia was it?? Quote Link to comment Share on other sites More sharing options...
Luke* Posted August 20, 2005 Report Share Posted August 20, 2005 Brian sells 1 Litre for $3.50 I fed half and put the other half in a bucket full of green water but they all died. Maybe the water was too foul? I think a paddling pool could work well. Quote Link to comment Share on other sites More sharing options...
clarkeymaster Posted August 20, 2005 Report Share Posted August 20, 2005 does anyone know of where i can get some daphnia from in auckland and once iv got them whats the best way in keeping them and how do i keep a culture of daphnia Quote Link to comment Share on other sites More sharing options...
Caryl Posted August 20, 2005 Report Share Posted August 20, 2005 I don't know where you can get them in Auckland but I have several old baths, fibreglass ponds and mussel floats in the yard which I just fill up with water and leave. They fill on their own with daphnia, mosquito larvae and other little critters. I have green water in a bath of goldfish so dump a bit of that in occasionally otherwise I don't feed them or anything. They slowly multiply and since I have few fish, and lots of containers, I have sufficient for my needs. They can be fed on grass clippings, dried sheep poo, dried blood or dried yeast. I have found they do not travel well and start to die after a couple of hours in a lidded container - I would put them in a 1kg peanut butter jar 1/3 filled with water. If I removed the lid every so often they were OK but keeping the lid on, despite the air gap, killed them pretty quickly. Quote Link to comment Share on other sites More sharing options...
Wok Posted August 20, 2005 Report Share Posted August 20, 2005 I should be able to part with a couple litres of the critters in about a couple weeks time . Had to reseed my bathtub as a whole bunch of rotten bananas was a tad too much for the daphnia and wiped them out with amonia coming off the rotting fruit Quote Link to comment Share on other sites More sharing options...
Caryl Posted August 20, 2005 Report Share Posted August 20, 2005 When I tried to keep daphina to begin with, I was told to use banana skins but found they rotted too quickly and formed a film on the water surface Quote Link to comment Share on other sites More sharing options...
Wok Posted August 20, 2005 Report Share Posted August 20, 2005 I have had no problems with banana skins.. Problem is putting too many in a bathtub... I think 1 whole banana a month is sufficient :-? been able to kill my daphnia by chucking in too many bananas. I find that lettuce leaf breaks up too easily and leaves bits floating all around the water so very difficult to get clean daphnia :evil: Quote Link to comment Share on other sites More sharing options...
Ira Posted August 20, 2005 Report Share Posted August 20, 2005 I found after I tossed a clump of old limp spinach into my pound my daphnia exploded. Quote Link to comment Share on other sites More sharing options...
HummingBird Posted August 20, 2005 Report Share Posted August 20, 2005 Give me a buzz when you've got some spare daphnia Wok - feel like trading some for some baby platys or guppies? :lol: Quote Link to comment Share on other sites More sharing options...
