The stress response of a freshwater Java barb to
different salinity concentrations was evaluated
using the levels of biochemical and hematologi-
cal parameters of blood and behavior as indica-
tors. Aquaculture urges for more accurate infor-
mation on stress control, in order to be assured of
good health status of fish, especially those trans-
ferred to a new environment. Environmental sa-
linity fluctuation can act a stressor and leads to
give information on behavioral and physiological
responses.
