Quality Status

During the last decade the Water Framework Directive (WFD) has driven scientific community endeavours towards the development of assessment tools to determine the Ecological Quality Status (EQS) for all surface waters, including transitional waters (TWs). Macroinvertebrates being used as Biological Quality Elements encouraged the development of distinct multimetric and multivariate indices, initially based on taxonomic approaches. Those indices were mostly developed for the marine environment and applied extensively on TWs. The main discrepancies in the ecological quality status assessment arise on TWs, partially due to the difficulty in discriminating the effects of natural stress from anthropogenic impact. As a response, indices following functional approaches are being developed and applied in assessing the EQS in these environments. Next, the validation and intercalibration of the metrics as well as the settlement of reference conditions are additional sources of variability inherent to any assessment. This paper aims at briefly presenting the different steps needed for the implementation of WFD on Mediterranean TWs. It highlights existing difficulties and possible research lines to be explored in order to reduce sources of variability and better assess the status of such water bodies.

Quality Status

In spite of the development and widespread dissemination of the model organic shrimp farming systems, the biological communities in the organic shrimp farming ponds have still very limited. Therefore, we conducted a field survey for macrobenthic communities (MC) of the Tam Giang‘s organic shrimp farming ponds (TGOSFP) located in Tam Giang commune, Nam Can district, Ca Mau province during three seasons in 2015 (March - dry, July - transfer and November - wet season). The results indicated that the MC have characterized by high density and slightly diversity that is a rich natural food sources for shrimp in the TGOSFP. Further more, the present study is a first attempt to use of new indices (AMBI - AZTI’s Marine Biotic Index) on MC for determining the ecological quality status of sediment (EcoQ) in the TGOSFP. The following results were also recorded with an undisturbed and slightly disturbed  EcoQ in the TGOSFP and the general EcoQ would likely be improved between three seasons. The success of AMBI for detecting EcoQ in Vietnam is specific to this study, but AMBI was likely to improved, in particular tropical regions.
