Biodiversity is a key factor for the functioning and efficiency of an ecosystem. Greece, though covering a relatively small surface area, hosts a great deal of species diversity. This is especially true for freshwater fishes. In recent years, the traditional methods of species identification have been supplemented by the use of molecular markers. T...

Maintaining and improving the aquatic ecosystems in the community is the aim of the Water Framework Directive (WFD) 2000/60/EC. The WFD requires the water quality to be classified into five categories. Lagoons are dynamic ecosystems. The fish communities inhabiting them are highly affected by the environmental conditions prevailing both in the fres...

The diversity of detrimental factors impacting the European eel and the number of involved stakeholders pose a challenge for an effective stock management. Knowledge on the economic consequences of single management measures is required to better assess their implications for the involved sectors. This study summarizes the current knowledge on thre...
Article
The determination of a proper minimum environmental flow in a river basin is one of the most critical components of sustainable water resources management, with hydraulic and habitat modelling being the most advance methods for that analysis. The present study illustrates the ecohydraulic modelling of Nestos River Delta at the deltaic zone of a hea...
Article
Preservation of a good ecological status in riverine habitats emerged as a priority for water management policies in Europe since the negative impact caused by the construction and operation of dams on the ecohydrology and habitat availability became more evident. Ecological flows, as reported in the recently published European guidance, represent...
Article
After the implementation of the Water Framework Directive 2000/60, biotic indices became an important tool aiming at assessing the water quality of all water bodies, such as lakes, transitional, coastal and groundwater, and the restoration of their ecological integrity.

The lagoons are the most fish productive ecosystems. In the area of River Evros Delta, there are two lagoons, Drana and Monolimni, in which no fishing activities are practiced since the first one was illegally drained in 1987 and the second one was abandoned in 2010. This study presents the results of a combined hydrological and ichthyological stud...

Goal: The European eel was classified as critically endangered by the International Union for Conservation of Nature (IUCN) after multiple factors – including habitat loss, overfishing, oceanic changes and an increase pollutant and pathogen levels – had collectively contributed to the decline of the species. In line with Recommendation GFCM/42/2018/1 adopted by GFCM countries, the GFCM research programme on European eel will aim to: * identify and assess management and protection measures for eel stock recovery; * establish a common framework for the monitoring of European eel; * collect and update data concerning eel stocks and habitat in the Mediterranean, and * establish a common framework for eel stock assessment. http://www.fao.org/gfcm/news/detail/en/c/1294637/#:~:text=In%20line%20with%20Recommendation%20GFCM,measures%20for%20eel%20stock%20recovery%3B&text=collect%20and%20update%20data%20concerning,habitat%20in%20the%20Mediterranean%2C%20and
