Journal of Applied Ecology, Volume 62, Issue 2, Page 231-241, February 2025.Previous maximum traversable water speeds for fish passage designs have been based on average swimming ability, but this approach only enables fish that are better than the average swimmers of their species to overcome barriers. This study highlights the importance of evidence‐based designs for successful fish passage solutions to account for the ...

A Jump‐Driven Self‐Exciting Stochastic Fish Migration Model and Its Fisheries Applications
Natural Resource Modeling, Volume 38, Issue 1, February 2025.ABSTRACT We introduce a stochastic continuous‐time model via a self‐exciting process with jumps to describe a seasonal migration event of diadromous fish exemplified by Ayu Plecoglossus altivelis altivelis. The dynamics of the stored population at a point in a river, waiting for their upward migration, increases by the inflow of fish from the ...

Ecology of Freshwater Fish, Volume 34, Issue 1, January 2025.Abstract Animal personalities are differences in behaviour among individuals of the same species that are consistent over time and contexts. The integration of animal personality into conservation actions is hampered by limited understanding of personality traits in non‐model organisms.

Swimming capacity and behaviour of juvenile round goby (Neogobius melanostomus)
Ecology of Freshwater Fish, Volume 34, Issue 1, January 2025.Abstract The round goby (Neogobius melanostomus) is an example of an invasive species where the adults are unimpressive swimmers and yet via human activities, they have managed to rapidly invade the Laurentian Great Lakes, the Baltic Sea and many rivers in Western Europe.

New Zealand Journal of Marine and Freshwater Research, Volume 58, Issue 4, Page 577-590, December 2024.ABSTRACT This paper reports the first observation of a giant kōkopu (Galaxias argenteus) spawning site in a tidal waterway and illustrates the usefulness of DNA barcoding for opportunistic discoveries that in this case involved the collection of a single egg.

Distribution, identification and biology of freshwater fishes in south-western Australia
, 1998 A total of 410 sites in the major watersheds in the south-western corner of Australia, bounded by Bunbury in the north-west and just east of Albany in the south-east, were sampled for fish.
