Habitat Preferences and Short‐Term Dynamics of Alien Fishes Revealed by Environmental DNA in River Floodplains

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Based on eDNA metabarcoding, the study revealed habitat‐use patterns and the temporal dynamics of non‐native fish species in two Danubian floodplains. Hydrological connectivity played a major role in shaping alien fish community assembly. ABSTRACT Floodplains are among the most diverse freshwater ecosystems, yet they are increasingly threatened by ...

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment

Fish and Fisheries, Volume 27, Issue 2, Page 160-178, March 2026.
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.
