Abstract:
... BACKGROUND: Fish telemetry using electronic transmitter or data storage tags has become a common method for studying free-swimming fish both in the wild and in aquaculture. However, fish used in telemetry studies must be handled, anaesthetised and often subjected to surgical procedures to be equipped with tags, processes that will shift the fish from their normal physiological and behavioural stat ...

Abstract:
... Salmon lice, Lepeophtheirus salmonis (Krøyer, 1837), are ectoparasites of the Atlantic salmon, their presence on the fish host is often linked to increased economic losses to the aquaculture industry in the northern hemisphere. Initial attempts to control parasite numbers primarily involved chemical treatment methods, however, there has been a gradual shift towards what are considered more environ ...
