Hucho hucho (Linnaeus, 1758): last natural viable population in the Eastern Carpathians - conservation elements
There is great variation in the conservation status of the last habitats with long-term natural viable populations of the salmon species Hucho hucho in Maramureş Mountains Nature Park, Eastern Carpathians (Romania). According to the specific guidelines for Natura 2000, 42.11% are in good conservation status, 31.57% are of average status, and 26.32% are in a partially degraded condition. In this study area, 6 main risk elements were identified related to human impact on the environment: poaching, minor riverbed mor-phodynamic changes, liquid and solid natural flow disruption, habitat fragmentation leading to isolation of fish populations, organic and mining pollution, and destruction of ripa…
Environmental Aspects of Implementation of Micro Hydro Power Plants – A Short Review
Abstract The economic importance of micro hydro power plants is obvious around the world and the development trend will continue well into the future. Unfortunately the effects on the local lotic systems habitats and biocoenosis are not studied, and in some cases or are known only to a small degree. A variety of taxa were identified in the study case areas as being significantly affected by the micro hydro power plants: macrophytes, macroinvertebrates and fish.
