Spread of Amazonian Freshwater Fishes Beyond Their Native Ranges

Fish and Fisheries, Volume 27, Issue 1, Page 56-67, January 2026.
ABSTRACT The spread and establishment of Amazonian species outside their native ranges through activities such as sport fishing, aquaculture, and the ornamental fish industry may lead to ecological changes in recipient ecosystems. We investigated the global distribution of Amazonian freshwater fish (AFF) and conducted a case study in the upper Paraná ...

Invisible dynamics: exploring the genetic diversity of peacock bass in Brazil

OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA
In Brazil, the introduction of non-native species into freshwater environments, such as peacock bass (Cichla spp.), was driven by aquaculture and sport fishing. These Amazonian fish possess phenotypic plasticity and resilience that facilitate their invasion and establishment in new habitats.

Beyond the Binary: Controlling Natural Sex‐Change in Hermaphroditic Fishes

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate ...
