I have spent a fair amaount of time shrimping in the Guolf of Mexico,
and there is a vast varied assortment of sizes, hence they have the
minimum mesh sized nets, so as to lety smallones escape and only
collect larger ones. There is a differenc ein what mesh size is
allowed by various states, and it makes a big diference in sizes yu
find. I would have to hink they are out in the gulf when they spawn,
or at least in the initial portions of a bay with a short access to a
pass to the gulf, for breeding a that was always the best polace to
get a fast limit of shrimp, because most recreational shrimpers did
not have the capbility to get down to the bottom off shore like the
commercial shrimpers did. I know on the bay we lived at which was less
than 1 mile to the gulf there was only a small difference in SG,
overall except for further back inland where fresh water by way of a
stream entered the bay. By the time that water got just a small bit
away it too was just as much SG as the gulf was....but that baya had
a ton of shrimp none the less.....but everyone seemed to migrate away
forom the influx of the freswh water, even though it was
brackish....(IIRC 1.019 or so). I remember osme readings as we used to
collect NSW on occassion for a local critter tank we kept up during
summer months and sometimes weather was not fit to go off shore even a
short distancet to get it so we did collect water in the safest areas
back then in and around the bays etc, and we always checked SG.

Immature shrimp around here (Florida) grow in fresh/brackish water, and
then move to the ocean when they mature (often during a good rain storm).

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.

So it looks like some are freshwater, some are marine and some are
brackish. The genus, from a bit of googling, is Palaemon - haven't
managed to indentify a tropical marine species ye
