Project: Analysis of mentum deformities in Chironomus (Chironomidae, Diptera) within the framework of the monitoring network of sediment quality Flanders, VMM

project duration
01-MAY-02 – 31-JAN-03
The biological assessment of the sediment quality in Flanders (monitoring network of sediment quality, VMM) is based on two indices, the Biotic Sediment Index (BSI) and the percentage mentum deformities in Chrionomus-larvae (Diptera, Chironomidae). Former large-scale monitoring programs showded that at only 30% of the sampling sites enough chironomid larvae were present to perform an appropriate assessment of the sediment. Therefore next to the analysis of the resident larvae an in situ test with Chironomus riparius is used to assess those sampling points.
