Abstract

Rivers and their corridors form complex ecosystems that include adjacent land, flora and fauna and the actual courses of water. Given the ecological criteria for prioritizing the rehabilitation of longitudinal continuity of watercourses recommended by the International Commission for Protection of the Danube River (ICPDR) (Appendix 1) and starting from the analysis of the Management Plan to ensure longitudinal continuity of watercourses in Some?-Tisa River Area (Annex 9.17.a in BMP – Basin Management Plan) there have been proposed several scenarios in order to facilitate fish species migration above the bottom sill from Apahida. The selected case study is focused on the mentioned discharge or bottom sill in Apahida town (hm 985) located 45 m downstream of the bridge located at the intersection of two streets; this bottom sill is 0.8 m high and was built in order to correct the slope, to reduce erosion and to enhance water oxygenation. Currently the bottom sill is supervised by Some?-Tisa River Basin Water Administration, Cluj SGA. One of the important migratory fish species in the study area is the Common Nase (Chondrostoma nasus) protected by Bern Convention (Appendix III); barbel (Barbus barbus)- rare species, protected Habitats Directive (Annex V),annex 4A of Low nr.462 and Red List of RBDD; bream (Abramis brama) bream (Abramis brama) - IUCN Red List of Threatened Species. The water catchment area of the Apahida commune in Cluj County blocks migration of various species of migratory fish such as: Common Nase (Chondrostoma nasus) protected by the Bern Convention (Appendix III); Barbel (Barbus barbus) - rare species, protected Habitats Directive (Annex V), Annex 4A of Low No 462 and Red List of RBDD; Bream (Abramis brama) Bream (Abramis brama) - IUCN Red List of Threatened Species. To help the three species of fish come the solutions proposed in this article.
