A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Slow growth rates of common carp Cyprinus carpio in English catch‐and‐release fisheries are related to high stock densities

Journal of Fish Biology, EarlyView.
Abstract Hatchery‐reared, domesticated strains of common carp Cyprinus carpio (‘carp’) are regularly used to enhance angler catch rates in many catch‐and‐release (C&R) lentic fisheries. These carp are usually selected for specific traits (e.g. stress resilience, high probability of angling capture) and are often stocked at relatively small sizes into ...

Reproductive plasticity and environmental tolerance of invasive African catfish (Clarias gariepinus) in a tropical Brazilian river

Journal of Fish Biology, EarlyView.
Abstract Invasive alien species (IAS) pose a significant threat to biodiversity, particularly when endowed with high ecological and reproductive plasticity. The African catfish, Clarias gariepinus, is one such species, widely recognized for its ability to colonize and establish in diverse tropical ecosystems.
