Abstract
Estuarine environments are home to adults and juveniles of many species, and often undergo fluctuations in dissolved oxygen and salinity. It is important to assess physiological effects of these fluctuations together as they often vary at the same time and place. Two experiments were performed, one with the penaeid shrimp Farfantepenaeus aztecus at two maturation levels (juvenile, adult), and under normal oxygen conditions or diel cycled hypoxia. The second experiment was with the caridean shrimp Palaemon pugio at 15 g kg-1 and 5 g kg-1 salinity, and under normal oxygen conditions or diel cycled hypoxia. After two weeks of experimentation, partial bioenergetic composition and oxygen consumption were quantified. Cycled hypoxia had no effect on body composition (protein and/or lipid) or oxygen consumption in both experiments suggesting both species from the estuarine habitat are well adapted to fluctuations in dissolved oxygen. Juvenile F. aztecus had higher percent lipid compared to adults, with no difference in protein composition, making them a good food source for predators. Palaemon pugio in the 5 g kg-1 salinity group had higher oxygen consumption compared to the 15 g kg-1 salinity group. Salinity had no effect on bioenergetic composition. There were no interactions between the factors in both experiments. Hyposalinity may be a stressor for P. pugio; however, the occurrence of salinity stress and hypoxia together do not appear to affect one another.
