This study assessed the fish communities’ diversity and structure spatial dynamic in the Timiş River, in correlation with the biotope characteristics to establish management measures.
The results are based on quantitative fish samples from 21 stations of the Timiş River, situated between its sources and the Romanian-Serbian border (241 km). The sampling campaign was conducted during 2011-2012.
In the reference zone 32 fish species were identified, belonging to 27 genera and nine families.
The fish associations present a high diversity along the entire Romanian sector of the Timiş River.
The fish communities’ diversity distribution patterns reflect the biotope conditions diversity and the human impact factors presence and degree on the Timiş River sectors. The fish communities’ diversity assessment in correlation to biotope characteristics allows the establishment of priorities, objectives and measures for the sustainable management of the studied river biodiversity.
