Improving eel pass efficiency: The role of crest shape and water flow in facilitating upstream juvenile eel migration

open access: yesJournal of Fish Biology, EarlyView.
Abstract River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endangered catadromous fish. Eel passes, or ladders, are frequently installed on riverine structures, such as dams and weirs, to mitigate barrier ...

Abiotic environmental factors contribute to spatial variation in boldness and exploration in guppies (Poecilia reticulata)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Research on wild fishes has tended to overlook the role of abiotic factors in shaping behaviours associated with boldness and exploration. This oversight could exist because small‐scale variation in the abiotic environment might seem unlikely to influence such behaviours. We challenged this assumption through research in the Trinidadian guppy (
