Hej Ole,
Iflg det her har lidt Rotifer højere næringsniveau, derudover gætter jeg på at Artemia(nyklækkedé) er for store til
SPS ?
Hi Doug
i was a bit surprised by your last statement so i went to check the nutritional stats of artemia vs rotifers in the Plankton Culture Manual from FAF.
Here are the numbers i found:
Rotifers (fed with nannochl.)
75% protein, 22% lipid
Rotifers (fed with yeast)
71% protein, 17% lipid
Adult artemia
62.8% protein, 7% lipid (this number for pre-adult stage)
Food type not specified
(all numbers before enrichment with Selco)
Also, the reported digestability of rotifer protein is 89-94% vs 83%-89% for artemia (study conducted with carps and rainbow trouts)
Conclusion?: Not very conclusive
Whereas rotifers contain more proteins, i think fishes are happier muching on adult artemia. More meat per bite.
But, i think, Steve you primarily want to feed your filter feeders eg feather dusters, so i think your better off with the rotifers.
(But brine shrimp are cooler to look at!)
Mvh
