Balancing Harvest and Habitat: A Framework for the Sustainable Management of Diadromous Galaxiids

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Managing New Zealand's diadromous Galaxias species and the associated whitebait fishery presents a complex challenge due to species‐specific differences in life‐history strategies, habitat requirements, and population dynamics that underpin responses to anthropogenic and environmental pressures.

Upstream passage of Galaxias maculatus and Galaxias brevipinnis: comparative behavioural assessment for improved fish pass design

, 2022
1. Customized fish passage solutions enhance the upstream passage of fish through low-head instream structures. These solutions are designed based on the behaviour of benchmark species, with the hope that they will also perform well for other species ...

Implementing Bayesian network models using expert elicitation for instream barrier assessment

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
We have demonstrated that BN modelling and expert knowledge can be used for assessing the likelihood of fish passage where empirical data are lacking or sparse. The probabilistic framework is consistent with the need to reflect that many structures are partial barriers to fish movement and cannot be represented accurately in a binary pass/fail ...

Fishing‐Induced Regulation of Diadromous Fish Subsidies in Stream Communities

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Seasonal migrations of diadromous fish transport marine‐derived nutrients into freshwater ecosystems, enriching communities and restructuring food‐web dynamics. By diminishing these migrations, fishing pressure could disrupt cross‐ecosystem connectivity, thereby altering predator–prey interactions and community size structure.

Effects of introduced trout predation on non-diadromous galaxiid fish populations across invaded riverscapes [PDF]

, 2013
We assessed the landscape-scale effect of predation pressure from trout on the population integrity and distributions of non-diadromous galaxiids in high-country streams of the South Island, New Zealand.

Population Ecology of Freshwater Mussels Hyridella narracanensis and H. drapeta in South‐Eastern Australia

Freshwater Biology, Volume 70, Issue 8, August 2025.
ABSTRACT Freshwater mussels are in decline worldwide, and their conservation is limited by a lack of understanding of species ecology and biology, particularly in the southern hemisphere. Hyridella narracanensis is a threatened species which is co‐distributed with a more abundant congener, H. drapeta.

Otolith microstructural and microchemical changes associated with settlement in the diadromous fish Galaxias maculatus [PDF]

Marine Ecology Progress Series, 2008
The presence of a settlement mark in the otoliths of the common galaxid Galaxias maculatus was validated by examining the relationship between changes in otolith microstructure and otolith microchemistry. Two methods were used to examine the microchemistry of otoliths: (1) laser-ablation multi-collector inductively-coupled plasma mass spectrometry (LA ...
