Technical Abstract: Enzyme linked immunosorbent assay (ELISA) was used to determine levels of the inducible heat shock protein 70 (hsp70) in response to prolonged anoxic conditions in juvenile Nile tilapia. This protein was detected in brain, liver, muscle and head kidney. A significant difference between treatments (p>0.01, n=30) was observed between control and hypoxia treatments in brain and muscle tissue. A significant difference was not observed in liver and head kidney tissues. Using stress proteins to measure environmental stress in field situations and natural populations is ongoing.
