Maroun River in Khouzestan province in south of Iran is one of the most important Iran water resources and it enters to international Shadegan Wetland (Biggest Iranian Wetland). It is very important that we have Fishways with high efficiency for each obstruction across the river such as Diversion Dams and Regulator Dams. The dominant family of fishes, which live in Shadegan wetland, is Cyprinidae family, which is resident at this wetland and Maroun River. On this river, there is one Reservoir Dam and four Diversion Dams that have been constructed by Khouzestan Water & Power Authority (K.W.P.A.). The Reservoir Maroun Dam has no facilities for fish migration and here is some efforts for finding a possibility for installing a suitable fish facility for this dam. Fishway of Jaeezan diversion dam on Maroun River constructed about 6 years ago and dose not have good efficiency and it is not functioning properly. During the migration season, fishes are trapped downstream of the dam. The first part of this paper belongs to results of study on finding rehabilitation for this Orifice-Weir type Fishway.

Abstract
Maroun River in Khouzestan province in south of Iran is one of the most important Iran water resources and it enters to international Shadegan Wetland (Biggest Iranian Wetland). It is very important that we have Fishways with high efficiency for each obstruction across the river such as Diversion Dams and Regulator Dams. The dominant family of fishes, which live in Shadegan wetland, is Cyprinidae family, which is resident at this wetland and Maroun River. On this river, there is one Reservoir Dam and four Diversion Dams that have been constructed by Khouzestan Water & Power Authority (K.W.P.A.). The Reservoir Maroun Dam has no facilities for fish migration and here is some efforts for finding a possibility for installing a suitable fish facility for this dam. Fishway of Jaeezan diversion dam on Maroun River constructed about 6 years ago and dose not have good efficiency and it is not functioning properly. During the migration season, fishes are trapped downstream of the dam. The first part of this paper belongs to results of study on finding rehabilitation for this Orifice-Weir type Fishway. Behbahan diversion dam on Maroun River, which has been constructed in 20 years ago, has no Fishway and the second part of this paper includes the results of study on finding a possibility for installing a Fishway at this dam.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
