✦ Synopsis
This study was conducted in a shallow fishpond located on the eastern side of Arcachon Bay, France.
Dissolved oxygen, pH and nutrient content (NH,, NO,, NO, and PO,) showed pronounced die1 variations.
These phenomena seemed to be directly controlled by biological processes. Microbially mediated degradation of organic matter constitutes the main source of nutrients in the water column and primary producers consume the major part of these products. These processes are closely coupled to the light-dark cycle.
Man-induced water renewal caused low modifications in nutrient concentration and did not alter its temporal dynamics.
