Here is some info from SRAC. Keep in mind the chemical make up of salts (Na & Ca ) when reading this.

Fingerlings that are sold should
be acclimated to cool water and
allowed to purge for at least a day
before being shipped. The shipping
water should be salted (0.5
to 1% or 5 to 10 g/L NaCl2, CaCl2,
or sea salt) to reduce the effects of
stress. A commercial anti-ammonia
compound is also added to
the water. If the fish are going to
be shipped by air (and sometimes
by ground) they are placed in a
few gallons of salted water and
into doubled plastic bags that are
inflated with oxygen and then
placed into an insulated shipping
box and sealed. Large shipments
by ground transportation are
loaded into insulated compartments
on a hauling truck that has
a supply of liquid oxygen and an
aeration system. Dissolved oxygen
should be kept above 5
mg/L. The water should be agitated
to prevent buildup of carbon
dioxide. Temperatures should
be kept below 70 °F (21 °C).


Hybrids are
generally stocked into freshwater systems
but they do well in salinities of
O to 25 ppt, and some can survive
salinities up to full strength seawater
(35 ppt). Dissolved oxygen levels as
low as 1 mg/l can be tolerated for a
short period of time, but optimum
dissolved oxygen levels range from 6
to 12 mg/1.

Alkalinity, hardness and pH levels
are usually related, and hybrid
striped bass grow well over a wide
range of values. Alkalinity of 100
mg/1 or above is desirable in culture situations; however, fish have been
known to survive alkalinity and hardness
values of 20 to 30 mg/1.[[ Mortality
can be significant during
transfer from water of high
alkalinity/hardness to water with low
alkalinity/hardness. Although still unproven,
calcium levels appear to be
important when handling fish in
freshwater.]] Hybrids survive in a pH
range of 6.0 to 10.0, although 7.0 to
8.5 is optimum for growth. Pond reared
hybrids have survived
repeated exposure to a pH of 2.5.
