Technologies for the study of hydropeaking impacts on fish populations: Applica...
Alexandre, Carlos M.; Quintella, Bernardo R.; Ovidio, Michaël; Boavida, Isabel; Costa, Maria J.; Palstra, Arjan P.; Lima, Rui L. Pedroso deDam construction and streamflow regulation are increasing throughout the world, with impacts in impounded aquatic ecosystems. Hydropower dams, some of them causing a phenomenon called “hydropeaking” during their operation, are known for having a variety of impacts on downstream aquatic biota, particularly fish, and respective habitat. This can result in significant changes, from the community (e.g., fish assemb...
Accelerometry of seabream in a sea-cage: is acceleration a good proxy for activ...
Palstra, Arjan P.; Arechavala Lopez, Pablo; Xue, Yuanxu; Roque, AnaActivity assessment of individual fish in a sea-cage could provide valuable insights into the behavior, but also physiological well-being and resilience, of the fish population in the cage. Acceleration can be monitored continuously with internal acoustic transmitter tags and is generally applied as a real-time proxy for activity. The objective of this study was to investigate the activity patterns of Gilthead ...
