| The catfish yellow-mandi, Pimelodus maculatus, is a valuable sporting and commercial fish of inland waters of Southeast Brazil including Igarapava Reservoir. It is a short-distance migrant that needs shorter stretches of free-flowing river to spawn compared to other Neotropical migrants. Igarapava Reservoir is one the 13 hydroelectric reservoirs, arranged in a cascade fashion, impounding the 1,300 km-long Grande River, SE Brazil. In this paper, we examined reproductive features and recruitment of the yellow-mandi in Igarapava Reservoir. We also evaluated the role of the Igarapava Fish Ladder (IFL) built around Igarapava Dam on the sustainability of its fisheries. Female adult yellow-mandis that were gill netted (nets of 8-20 cm stretch-mesh) during the... |

| Fish passages are considered the oldest management tool used to minimize the impact of blocking fish migratory routes by hydroelectric power plants. However, fish passages are being installed without specific criteria in Brazil, with severe consequences to the conservation of the local fish fauna. Therefore, basic data gathered for fish passages already constructed could contribute to define operational rules, in addition to offer subsidies to decision-making and design of future facilities. Thus, the fish ladder of Baguari Dam was evaluated regarding temporal distribution, attraction, and ascension of the local fish fauna. A total of 20 fish samples were conducted immediately downstream of the dam and inside the fish ladder, from January 2010 to June... |
