Morphometric Traits, Length–Weight Dynamics and Condition Indices of Invasive Vermiculated Sailfin Catfish (Pterygoplichthys disjunctivus) in Bangladesh: Management Implications

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT The vermiculated sailfin catfish (Pterygoplichthys disjunctivus), an invasive species, has rapidly proliferated in Bangladesh's freshwater ecosystems, threatening native biodiversity. This study examined its morphometric traits, length–weight dynamics, condition factors and relative weight over a one‐year period (August 2023–July 2024) in the ...

Anthropogenic Factors Drive the Depletion of Fish Functional Β Diversity Within and Outside Two National Reserves in the Peruvian Amazon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...
