Do cage fish farms promote interference in the trophic niche of wild fish in neotropical reservoir?
(2022-04-01)
Cage fish farming in hydroelectric reservoirs has been reported to promote variations in environmental conditions, which directly interfere with the foraging behavior of wild fish. We have hypothesized that the abundance ...
