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 ...
Interference of cage fish farm on diet, condition factor and numeric abundance on wild fish in a Neotropical reservoir
(2013-11-15)
Historically, the ichthyofauna of large Brazilian rivers has been subject to anthropogenic interference, such as impoundments. Currently, cage fish farming systems are a new source of impact on aquatic ecosystems. The ...

Parasite infection and immune and health-state in wild fish exposed to marine pollution
(Elsevier, 2017-06)
Association between parasitism and immunity and health-state was investigated in wild Sebastes oculatus after having determined that pollution exposure is associated with altered immune and health-state parameters. Given ...
Epitheliocystis in wild marine fishes and its relation with anthropogenic pollution
(Wiley Blackwell Publishing, Inc., 2021-06)
Epitheliocystis is a fish disease with recorded in increasing numbers globally. Here we show that (a) pollution-exposed wild marine fishes have higher infection prevalence than nonexposed individuals from reference sites, ...

Genetic diversity and structure of the commercially important native fish pacu (Piaractus mesopotamicus) from cultured and wild fish populations: relevance for broodstock management
(Springer, 2021-02)
Pacu (Piaractus mesopotamicus) is one of the most important Neotropical freshwater fish species produced by aquaculture in South America. This study is the first attempt to inquire about aquaculture stocks in Argentina ...
