AbstractThis study evaluates the effectiveness of two fish passes at two hydropower dams (Canoas I and II) in the Upper Parana basin, which form part of a cascade of three reservoirs. Fish from 12 migratory species (3089 ...
Energy deficit does not affect immune responses of experimentally infected pacu (Piaractus mesopotamicus)
(Elsevier B.V., 2015-04-01)
We investigated if the energy deficit following a 30-day starvation period could affect the ability of fish to mount immune responses after experimental exposure to Aeromonas hydrophila. Fish were submitted to two feeding ...
