Quantitative Assessments

The output of monitoring programmes such as the National Aquatic Ecosystem Biomonitoring Programme must be used in the management of aquatic ecosystems. To achieve this, collected data must, through a systematic framework, be linked to measurable management objectives. This paper demonstrates how the results obtained with biological indices and system-specific knowledge, are combined to derive semi-quantitative assessments of ecosystem condition. These assessments provide the basis for responding to the results of a river monitoring programme.

Bioindication Methods

Bioindication methods are applied in ecotoxicological studies which in turn are widely used in the biological monitoring of surface water. Bioindication has been applied for a long time and so far it has created multiple classificationsbased on diagnosis groups of organisms. Bioindicators play a signi]cant role in bioindication; they are species used to monitor the health of the environment or ecosystem. Some of them are standard test organisms used in ecotoxicologyin the so-called bioassays, which provide a great deal of information about the type and in^uence of pollution. These studies are vital nowadays, as compounds have been found to be the greatest threat to aquatic ecosystems. In relation to ecotoxicology, research allows us to determine bioconcentration, bioaccumulation and biomagni]cation factors, and to assess the ecological status of water used in many different indexes so as to determine such relevant parameters as saprobic, biological bio-diversity and biotic indexes. Poland is preparing for the extension of monitoring systems that take into account all the necessary elements of the environment, even the sediments. It is required by the Water Frame Directive.

Aquatic resources are increasingly stressed primarily due to anthropogenic activities in Ethiopia. These anthropogenic stresses altered ecological integrities and compromised ecosystem services that could otherwise support the livelihoods of millions of people. Evidence-based management of the degradation of aquatic ecosystems requires quantifying ecologically significant changes and discriminating among impact levels and types. Apart from physico-chemistry, monitoring of aquatic ecosystems using biological organisms is progressing well in recent times both in the tropics and temperate regions. The majority of studies so far focused on macroinvertebrates and to a lesser extent on diatoms. Though the method is given less attention, individual initiatives have been increasing over time especially in developing countries, including Ethiopia. This paper reviews current efforts undertaken and major challenges facing the use of bioindicators in aquatic ecosystems as biological monitoring tools. The possible application of biomonitoring and its importance for Ethiopian aquatic ecosystems is also discussed and future improvements suggested.
