Morphological and Histometric Alterations in Gonadal and Neural Tissues of Native and Non‐Native Fishes From the Lower Doce River Basin in Southeastern Brazil

Anatomia, Histologia, Embryologia, Volume 55, Issue 5, September 2026.
ABSTRACT The ichthyofauna of the lower Doce River basin has been exposed to multiple anthropogenic stressors. Among these, the collapse of the Fundão mining tailings dam in Mariana, Minas Gerais, Brazil, in 2015 resulted in massive fish mortality and widespread contamination of aquatic environments.

Adaptive Diversification of the Mstnb Locus Drives Genomic Architecture of Growth in Thai Clariid Catfish

Evolutionary Applications, Volume 19, Issue 9, September 2026.
ABSTRACT The production of clariid catfish in Thai aquaculture depends on culture of the native species (Clarias macrocephalus and C. batrachus) and introduced African catfish (C. gariepinus). Particularly, hybridization with C. gariepinus has improved productivity but raised significant conservation concerns.
