Summary
Hypoxia causing mass mortality was first documented in the Krka estuary (Yugoslavia in that time) in 1969. Hypoxia is episodic, developing in autumn in response to stratification and degradation of phytoplankton. In the absence of autumn rains, hypoxia may last throughout the winter. In 1998 hypoxia was severe enough to cause massive mortality of benthic macrofauna. Decomposition of the macrofauna further increased hypoxia.
