ABSTRACT This study presents data on the effect of temperature and fluctuations in salinity on the oxygen consumption, nitrogen excretion, and osmoregulation of Litopenaeus stylirostris juveniles to determine the combinations, so these can be used to optimize the culture conditions. The oxygen consumption rate of juveniles acclimated to 23[degrees]C, 28[degrees]C, and 33[degrees]C was measured. Fluctuating salinity levels were applied to these organisms in a sequence of 40[per ...
<0.05) on the oxygen consumption of the blue shrimp, but the effect of salinity and the interaction temperature-salinity was not significant (P><0.05), the interaction between temperature and salinity was not significant (P><0.05) on the hemolymph concentration of the shrimps; the temperature and the interaction between temperature and salinity did not have a significant effect (P><0.05) the hemolymph was hypo to hyper-osmotic since in the salinities of (40[per thousand], 32[per thousand], 40[per thousand]) had an interval of-417 to -167, whereas the salinities of (25[per thousand], 16[per thousand], 25[per thousand]) increased from 18[per thousand] to 143[per thousand] (Fig. 4). The temperature did not affect significantly (P>
