Biological bases for whitebait culture Galaxias maculatus (Jenyns, 1842): a review
Latin American Journal of Aquatic Research, 2017 Galaxias maculatus (Jenyns, 1842), is a gourmet fish of great commercial importance with overexploited fisheries. So, studies of its biology are essential in order to develop a technology for its cultivation (galaxiculture), which is at a pilot stage. The goals of this work are: 1) to provide a synthesis of the literature information on the biology of ...

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 2, Page 339-355, June 2025.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.

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.
