Acoustic and Light Selective Behavioral Guidance Systems for Freshwater Fish

The use of non-physical barriers, particularly based on acoustic and luminous stimuli has been historically used to influence the behavior fish, mainly for fishing purposes. Nowadays, behavioral barriers guidance systems have developed, not only deter movements but also promote responses with objective native fish protection, in particular potamodromous species, reducing their mortality hydraulic structures dams guiding them towards transposition or replacement habitats regularized water bodies. This review details evolution recent years (Scopus 2012–2019) development selective fish. We found that technologies try identify new sensory ranges. Ambient sound, sound predators spectral bands different wavelengths selectively stimulate target non-target order improve effectiveness repulsive/attractive Guidelines future research area are present.
