nunomiguel Publicado Outubro 21, 2004 Publicado Outubro 21, 2004 Olá, Retirado de: http://www.waynesthisandthat.com/brineshrimp.htm Would you believe fresh-water brine shrimp? This sounds like a contradiction in terms but it works. I tried hatching both decapsulated and regular brine shrimp eggs in water without salt and discovered that they hatch just fine in plain, unsalted water, as long as there is some baking soda added to incease the PH enough to an enzyme they release to dissolve a hole in their cysts. The advantage of doing so is that when they are added to the fry tank, they don't experience a large osmotic shock from going form salt to fresh water. The brine shrimp hatched in fresh water tend to last longer in the fry tank, which seems to confirm the advantage. I also tried hatching brine shrimp in water with no baking soda (used to bring the PH up into the 8-9 point range). It didn't work. The high alkalinity is needed to them dissolve part of their egg case. Decapsulating does not . they don't experience a large osmotic shock from going form salt to fresh water. The brine shrimp hatched in fresh water tend to last longer in the fry tank Alguém já experimentou? Esta história do "choque osmótico" funiona assim como descrito? Citar Cumprimentos, Nuno

À franqueza dos outros chamamos insolência. Um tolo encontra sempre outro tolo, ainda maior, que o admira.
