 The potential spawning grounds for native cyprinids are scarce in the studied reach (six in total), representing less than 2% of the riverbed area. The low availability of spawning grounds seems to be influenced by the floodable areas of both HPP reservoirs. Moreover, the spawning areas show excessive silting.
-Regarding Guma and Vadocondes fishways efficiency, 52% (211/411) and 31% (27/87) of the tagged fish (''L. bocagei'' and ''P. duriense''), respectively, were detected during their upstream movement. The ascent success for Guma was 61% (129/211) and 70% (19/27) for Vadocondes. Median ascent time was less than 4 h, with a median time per meter of ascended height of 26 min/m in Guma and 6 min/m in Vadocondes. These values seem to indicate that both structures do not cause an important migration delay for the tagged fish species. Recorded fish movements were related to water temperature and peak flows (Figures 1 and 2).

Recorded fish movements were related to water temperature and peak flows (Figures 1, 2 and 3).
 In addition, the collected data reveals that Guma fishway can be a downstream migration route, as well. Regarding the fish that were released upstream Guma dam, 42% (144/343) were found in the fishway and 64% (92/144) of these fish completed the descent.
