Oxygen consumption from air and water, ammonia and urea‐N excretion, and Na + fluxes during progressive aquatic hypoxia in Amazonian armoured catfish Pterygoplichthys gibbiceps and Pterygoplichthys pardalis

Journal of Fish Biology, Volume 108, Issue 3, Page 867-880, March 2026.
The Amazonian loricariid fish Pterygoplichthys gibbiceps, from the Rio Negro, and Pterygoplichthys pardalis, from the Rio Solimões, are facultative air‐breathers that can use the stomach as an air‐breathing organ.

Is it there?—Estimating the invasion of armored sailfin catfish (Pterygoplichthys sp.) in the water bodies of Eastern Ghats, India using the eDNA approach

Environmental DNA
Early detection of invasive species is crucial for effectively controlling the potential damage they can inflict on the ecosystems. In contrast to the many limitations that conventional detection methods like visual surveys and netting hold ...

Invasive Amazon sailfin catfish (Pterygoplichthys pardalis) impacts the survivability and growth of native food fishes in India

Aquatic Living Resources
The prevalence of sailfin catfishes (Pterygoplichthys spp.) in inland waters, including vast aquaculture systems of India is rising. This might be a serious threat to the country’s native freshwater biological resources and aquaculture production ...

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil. [PDF]

J Fish Biol
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Fish Diversity and Environmental Relationships in the Jinsha River During the Initial Phases of the 10-Year Fishing Ban: A Metabarcoding Approach. [PDF]

Ecol Evol
Using eDNA metabarcoding, we identified 61 fish species in the Jinsha river during the early stage of the Yangtze river fishing ban. Fish diversity showed seasonal and regional variation, with Cypriniformes as the dominant group. Key environmental factors like temperature and dissolved oxygen were closely linked to diversity patterns.

Establishing new grid-size-dependent attributes to rank areas of endemism for conservation priorities. [PDF]

Cladistics
Abstract Delineating Areas of Endemism (AEs) is crucial for identifying priority areas for biodiversity conservation in a spatial planning framework. Endemicity Analysis in the NDM/VNDM software is one of the primary methodologies for its delineation.
