Abstract

This paper draw attention to the problems related to fish migration in the Crisul Repede River, from the Crisuri catchment’s area and restoring the longitudinal connectivity of the river, in Oradea City. On this sector fish migration routs were interrupted by the presence of a large number of obstacles that strongly influence local lotic ecosystem. The purpose of the paper is to present two innovative technical solutions designed to facilitate the passage of migratory fish species (Barbus barbus and Chondrostoma nasus) upstream the weir, placed near the Velenta railway bridge from Oradea. The two migration systems presented in the paper are a good solution for fish migration and their implementing could be an important step in solving the problems regarding the hydromorphological pressures on water bodies and achieving a good ecological potential of heavy modified water bodies.

Keywords: fish pass, weir, Velenta Bridge, Crisul Repede
