carla Posted January 18, 2007 Report Share Posted January 18, 2007 With my Daphnia culture going great I wondered if anybody has ever compared the food value of brineshrimp versus Daphnia for feeding fry. Everybody is dead keen on the brineshrimp which seem just another thing one has to attend to, while the Daphnia do it all themselves! So I wondered if anybody ever did a comparison?

alanmin4304 Posted January 18, 2007 Report Share Posted January 18, 2007 I don't know scientically but I would suspect daphnia would be about equivalent to adult brine shrimp which would make newly hatched nuplii better than both because they have the adition of the unused yolk sac. I feed small daphnia to larger fry as well as brine shrimp nuplii and microworm-- that way it is hard to go wrong. Quote Link to comment Share on other sites More sharing options...
Wok Posted January 18, 2007 Report Share Posted January 18, 2007 I believe that Newly hatched Brine shrimp are better than daphnia in nutritional value. also the BBS are much smaller than Daphnia so easily eaten by the "Fries" Quote Link to comment Share on other sites More sharing options...
carla Posted January 18, 2007 Author Report Share Posted January 18, 2007 I find it so easy to put a net full of daphnia into the tank and as they get babies all the time the fry can eat the baby-daphnia and the big Daphnia is filtering the water at the same time. I feed some flake in addition. Quote Link to comment Share on other sites More sharing options...
alextret Posted January 19, 2007 Report Share Posted January 19, 2007 I believe that daphnia naupli are even smaller than brine schrimp naupli. But to catch them one would need a "brine schrimp net", which is dense enough not to let them through. So far, I could not figure out where to get a "brine schrimp net".

alanmin4304 Posted January 19, 2007 Report Share Posted January 19, 2007 I bought a set of 4 of different grades right down to very fine. Works a treat for bbs and for grading daphnia. I can't recall if it was from someone on this site or from Trademe but I am very happy with them. Quote Link to comment Share on other sites More sharing options...
carla Posted January 20, 2007 Author Report Share Posted January 20, 2007 I bought some sieves in Germany years ago. They are just square plastic with different mesh sizes in the bottom. I am sure they were originally for Artemia not Daphnia - but work just as well! They are also available in sets: The sieves are (in mm): 0,18 0,30 0,56 0,90 Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted January 20, 2007 Report Share Posted January 20, 2007 They are the ones I use-- very good Quote Link to comment Share on other sites More sharing options...
Caryl Posted January 20, 2007 Report Share Posted January 20, 2007 I've got them except mine are round at the top Quote Link to comment Share on other sites More sharing options...
alextret Posted January 20, 2007 Report Share Posted January 20, 2007 Thank you very much for your answers, I'll keep an eye on trademe. I have a small outside pond that produces enough to feed ten adult fishes. I'm sure it should have more than enough infusoria, daphnia naupli etc. to feed fry, if I could only catch them.

alanmin4304 Posted January 20, 2007 Report Share Posted January 20, 2007 If you put them in order course to fine and pour your daphnia culture through you get them nicely graded to size Quote Link to comment Share on other sites More sharing options...
HandS Posted January 20, 2007 Report Share Posted January 20, 2007 I have feed bbs and daphina in the same tank (bbs to fry & daphina to the parents) and im 99% shure the daphina were eating the bbs. Surly this would be the SUPER SNACK for fish 8) Quote Link to comment Share on other sites More sharing options...

AMAZONIAN Posted February 3, 2007 Report Share Posted February 3, 2007 Hi All I will always stand to be corrected by "experts"; but a "CAWTHRON INSTITUTE" report on our (NZ Produced) Brine Shrimp as opposed to Rotifers, Daphnia and other fresh water "foods" state that; The nutritional value of "NEWLY HATCHED".................... Brine Shrimp: Protein............80% Fat.................1.5% Fibre...............4.8% Daphnia: Protein............52% Fat...................8% Fibre...............6.9% NOTE: Too much Daphnia can keep fish thin due to the amount of roughage in it's constitution. Both foods are there to complement each other. Daphnia is a natural resource while Brine Shrimp is a "MAN MADE" super food for the hobby.

HummingBird Posted February 4, 2007 Report Share Posted February 4, 2007 Yeah, baby brine shrimp is more nutritional but you can't beat the price of Daphnia. Quote Link to comment Share on other sites More sharing options...
Johannes Visser Posted February 4, 2007 Report Share Posted February 4, 2007 We use newly hatched, Brine Shrimp, on our Mbuna Fry twice daily and they seem to double in size with in a few day, have not used Daphnia. But each person has his or her own way, you need to do what you feel is best for your fish, lifestyle and pocket ! Quote Link to comment Share on other sites More sharing options...
carla Posted February 12, 2007 Author Report Share Posted February 12, 2007 Can anybody understand this auction? It says: Decapsulated artemia eggs. The hatched nauplii are shell-free therefore it is hassle free and no waste shells to remove. No hatching required, just feed directly to fish. Now DO you hatch these or not :roll: Quote Link to comment Share on other sites More sharing options...
evilknieval69 Posted February 12, 2007 Report Share Posted February 12, 2007 I think that you can hatch them if you want, but you dont need too Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted February 12, 2007 Report Share Posted February 12, 2007 They have removed the shell with chlorine and the contents are dead and dried. Best to soak them before feeding and they have the full nutritional value of newly hatched brine shrimp. I think the live ones are better because the fish instinctively snap at live food-- more work though. Quote Link to comment Share on other sites More sharing options...
fishboi Posted February 12, 2007 Report Share Posted February 12, 2007 I think that you can hatch them if you want, but you dont need too yeah if u decapsulated the eggs ur self i can hatch them or feed them straight but i thought the ones for sale on TM couldn't be hatched, guess i am wrong Quote Link to comment Share on other sites More sharing options...
AMAZONIAN Posted February 12, 2007 Report Share Posted February 12, 2007 HI All. Alanmin4303, I understood that the decapsulated form were not as nutrious as newly hatched live nauplii. :oops: It was something to do with the chemicals used in the decapsulating process. :roll: They are easier to feed as you just have to soak them for a bit and then feed them; not as time consuming as hatching your BBS, but for the food value I'll personally stick with the newly hatched product.

alanmin4304 Posted February 12, 2007 Report Share Posted February 12, 2007 Amazonian you may be correct. I tend to think a fish would prefer live food and they are also more "in the face" because they are swimming rather than sitting on the bottom. I have bought some from a different source and have also decapsulated some eggs that did not hatch well. Still prefer the live ones from the coke bottle trick.

caserole Posted February 12, 2007 Report Share Posted February 12, 2007 The only decap b/s eggs that will hatch come in a concentrated brine solution, to keep them dehydrated and are expensive. Any decap that come at that price and free-flow ( that is not in a brine solution ) have been decap'ed at a higher temperature then the shrimp can survive = they are non-hatching. As for weather they are better or not I suppose depends on what your feeding. I use both hatched and decap. Quote Link to comment Share on other sites More sharing options...
fishboi Posted February 13, 2007 Report Share Posted February 13, 2007 i decap my before hatching them just because its less messy with out all the shells floating around after hatching. Quote Link to comment Share on other sites More sharing options...
