Ecological quality status of sediment

Several genera dominated in Tri An Reservoir such as Daptonema, Rhabdolaimus, Udonchus, and Neotobrilus indicated for organic enrichment conditions. The percentage of cp3&4 and MI (Maturity Index) value in the dry season was higher than that in the pre-rainy season expressed the ecological quality status of sediment in the dry season were better than those in the pre-rainy season.

The purposes of this work are to (i) identify free-living nematode communities and the environmental variables in an organic shrimp farms ponds, (ii) determine the correlation between dominant nematode genera with main environmental variables and (iii) detect the EcoQ in Tam Giang’s organic shrimp farms ponds (TGOSFP) through dominant nematode genera and MI value.

The following results were also recorded that abundance/biomass comparison (ABC) method has been used successfully for detecting the ecological quality status of sediment (EcoQ) in Tam Giang’s organic shrimp farming ponds. The results indicated that unfavourable deflections (stress) in EcoQ of Tam Giang’s organic shrimp farming ponds throughout the dry - transfer - rainy season. More specificall.
