Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

open access: yesJournal of Fish Biology, EarlyView.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

open access: yesJournal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Validating gut flushing as a non‐lethal sampling technique for diet monitoring in agastric fish

open access: yesJournal of Fish Biology, EarlyView.
Abstract Non‐lethal diet sampling is essential where individual‐level monitoring and welfare matter, yet evidence on season‐long outcomes in agastric fishes is scarce. We tested syringe‐based gut flushing in pond‐reared common carp Cyprinus carpio over one growing season (April–September) using PIT‐tagged fish assigned a priori to three handling ...
