“…Projects of unclogging the existing barriers in a form of either dams with inactive fish passes or water barrages without any systems supporting migration of fish were implemented on the rivers: Ialomiţa, Somes Mic and Micheşul, Someşul and Hârtibaciu in the Romanian Carpathians. As a result, bypasses for fish were designed, riffles with increased roughness and fish ladders (Voicu and Bretcan, 2014;Voicu et al, 2015;Voicu and Dominguez, 2016;Voicu and Miles, 2016;Voicu and Baki, 2017).…”

The aim of study The aim of study was to determine, how the pool fish pass located on the Dłubnia River operates and to formulate recommendations, due to which it will work effectively and will not be an obstacle for migrating fish. Materials and methods Field work. Identification of elements of fish pass that may restrict fish migration on the grounds of standard geometrical dimensions. An attempt to design its repair. Results and conclusions The fish pass does not operate effectively. The paper presents recommendations for its improvement.

We propose a technical solution for fish movement based on the flow of water over a spill threshold. Such barriers are common in the Danube system. The proposed system has a range of operating components which are easily detachable from the spill threshold, are resistant to corrosion and will not harm the fish. In fact, if designed to complement swimming abilities of target fish, it should provide adequate passage for both adults and juveniles. If implemented correctly, the design may offer a solution to help displaced fish recolonize upstream habitats. RÉSUMÉ: La fragmentation des populations piscicoles du Caraș Supérieur (bassin du Danube) -proposition technique de réhabilitation.Nous avons proposé une solution technique pour le déplacement des poissons à l'aide de l'écoulement de l'eau au-dessus d'un déversoir. Des tells barrières sont fréquents dans le système hydrographique du Danube. Le système proposé est formé d'une série de composantes opérationnelles facilement détachables du déversoir, résistant à la corrosion et dont la forme ne blesse pas les poissons. En fait, s'il est projeté la capacité de nage des poisson cible aidant, il devrait fournir un passage adéquate pour les adultes ainsi que pour les juvéniles. Si correctement implémenté, le design pout fournir une solution aidant les poisson délocalisées à recoloniser les habitats en amont.REZUMAT: Fragmentarea populațiilor piscicole de pe Carașul superior (Bazinul Dunării) -propunere tehnică de reabilitare.Am propus o soluție tehnică pentru deplasarea peștilor cu ajutorul fluxului apei peste un prag deversor. Astfel de bariere sunt frecvent întâlnite în bazinul Dunării. Sistemul propus are o serie de componente de operare care se pot demonta ușor de pe pragul deversor, sunt rezistente la coroziune, iar forma lor nu rănește peștii. Mai mult, dacă este proiectat pentru a veni în întâmpinarea capacității naturale de a înota a peştilor țintă, ar trebui să permită trecerea în condiții adecvate, atât pentru adulți, cât și pentru juvenili. Dacă se implementează în mod correct, proiectul poate fi o soluție pentru a permite recolonizarea habitatelor din amonte de către peştii dislocaţi din habitat.Unauthenticated Download Date | 5/13/18 7:48 AM
