Fish pass use by shads (Alosa alosa L. and Alosa fallax (Lacépède, 1803)): impl...
Belo, A.F.; Cardoso, G.; Pereira, E.; Quintella, B.R.; Mateus, C.S.; Alexandre, C.; Batista, C.; Telhado, A.; Quadrado, M.F.; Almeida, P.R.Fish pass monitoring is essential to ensure the device's effectiveness as a mitigation measure for river impoundment, guaranteeing the longitudinal continuity of rivers, which is particularly important for diadromous fish that depend on obligatory migrations to freshwater reproduction (anadromous) or feeding areas (catadromous) to complete their life cycle. The upstream migration of the anadromous allis (Alosa ...

Proposals for optimizing sea lamprey passage through a vertical-slot fishway
Pereira, E.; Cardoso, G.R.; Quintella, B.R.; Mateus, C.S.; Alexandre, C.M.; Oliveira, R.; Belo, A.D.F.; Telhado, A.; Quadrado, M.F.; Batista, C.Movement of sea lamprey through a vertical‐slot fishway (built at the Coimbra dam,in central Portugal) was continuously monitored between 2013 and 2016 by a videorecording system. Visual count data were used to quantify the overall successfulmovements and identify seasonal and circadian patterns of fishway use. Explicativemodels (Boosted Regression Trees) were used to study the relationship between frequencyof ...
Performance of a vertical slot fish pass for the sea lamprey Petromyzon marinus...
Pereira, E.; Quintella, B.R.; Mateus, C.S.; Alexandre, C.M.; Belo, A.D.F.; Telhado, A.; Quadrado, M.F.; Almeida, P.R.In 2011, a vertical-slot fish pass was built at the Coimbra Açude-Ponte dam (Mondego River, Portugal), approximately 45 km upstream from the river mouth. The performance of this infrastructure for sea lamprey passage was evaluated between 2011 and 2015 using several complementary methodologies, namely radio telemetry [conventional and electromyogram (EMG)], passive integrated transponder (PIT) telemetry and ele...
