Immature shrimp around here (Florida) grow in fresh/brackish water, and

Not sure on their breeding behavior. That is, do mature shrimp return to
rivers to spawn? No idea.

I'm thinking that these are the same species of Ghost Shrimp taken at
different stages of life, or maybe the small ones have been acclimated
to salt water.

Not quite the same thing, but I'm guessing much the same principle
applies with FW Ghost Shrimp.....a while back I did quite a bit of
research on how to breed Amano Shrimp....in this case, the adults spawn
in freshwater....once the "fry" hatch they are immediateley swept out to
sea/brackish water....as they develop they make there way back to the
freshwater again where the adults live - that's a bit simplified but
pretty much the principle is there....

Now, from what I've read about breeding these in a tank...the key is to
remove the young shrimps as soon as they have hatched and put them
straight into salt water....as they grow slowly start adding freshwater
into the tank until the salt level is minimal - and there you have it -
amano shrimps - if anyone ever did this, I would suggest that selling
the amano shrimps would be far more lucrative than using them as food....

When it comes to Ghost Shrimp - they seem, at least in the US, to be a
lot cheaper - Amanos you are talking £20 for two....so getting
freshwater Ghost Shrimps to breed and raising the offspring in
sal****er/brackish might be an option for food (but I'm not entirely
sure that Ghost's follow the same breeding pattern as Amanos)....there
do appear to be brackish and sal****er species of the same genre....the
key, I guess, is knowing what you have bought rather than relying on the
common name....
