ABSTRACT We investigated the effects of native common bully (Gobiomorphus cotidianus) and non‐native western mosquitofish (Gambusia affinis) on zooplankton assemblages in an outdoor mesocosm experiment. Twenty‐one 100 L mesocosms containing zooplankton were assigned either four G. cotidianus, four G. affinis, or were left as a control group (i.e.

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
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 ...

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)
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.

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.

Optimizing eDNA Replication for Standardized Application in Lotic Systems in Aotearoa, New Zealand
The objective of this study was to optimize eDNA sample replication for the consistent characterization of freshwater fish and aquatic macroinvertebrate communities in flowing New Zealand waters, and ultimately, to inform the development of robust national monitoring standards. Results indicated that six replicates were needed to consistently detect 89.
