Ignored Dam-Fish Ecological Relations and Dam Management Activities Risk Knowledge Capital – A Protected Area Lotic Ecosystem Case Study (Gura Golumbului Dam Lake, Nera/Danube Watershed)

This work presents data on the fish identified in the lentic sector of the Golumbilor Lake and upstream and downstream lotic proximal sectors in two periods. The first is before ruthless management of the liquid and solid lake sediments (in 2022) and one after it (in 2023), presenting in a comparative way the modifications in the ichthyofaunal structure. The most striking change observed in the fish fauna of the downstream lake habitats is the replacement of fish species characteristic of lotic habitats with those typical of lentic habitats, which reflects the significant change in habitat characteristics due to this specific human impact.
