Family Galaxiidae Müller, 1846. Diagnosis (modified from McDowall & Frankenberg 1981). Distinguished by the following combination of characters: small to medium sized (39–580 mm); body elongate, generally cylindrical to laterally compressed, scale-less; primary trunk lateral line as a series of closely-spaced superficial neuromasts within a mid ...

ABSTRACT Intermittent streams dominate global river networks and are becoming increasingly common due to global change. Understanding the mechanisms by which freshwater biota respond to flow recession, drying, and intermittence is therefore important to our ability to support biodiversity as ecosystems adapt to ongoing stressors.

A Tasmanian landlocked population of the normally diadromous fish Galaxias maculatus (Jenyns) [PDF]
A landlocked population of the normally diadromous fish Calaxias maculatus is recorded for the first time from Tasmania. The differences between the landlocked population and normal diadromous C. maculatus are examined and discussed. The association with

Reproduction in Galaxias fasciatus Gray (Salmoniformes : Galaxiidae) [PDF]
A study of the reproductive cycle was made on Galaxias fasciatus Gray from streams on Banks Peninsula, South Island, New Zealand. There was no spawning migration; adults remained in the usual adult habitat to breed.

La familia Galaxiidae está representada, en Chile, por cinco especies. El estado del conocimiento de ellas es en general escaso, excepto en el caso de G. maculatus debido a que ha adquirido un gran interés económico. Por otro lado, G.

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.

Biological bases for whitebait culture Galaxias maculatus (Jenyns, 1842): a review [PDF]
Galaxias maculatus (Jenyns, 1842) es un pez gourmet de importancia comercial cuyas pesquerías están sobre-explotadas, siendo esencial el estudio de su biología para desarrollar su tecnología de cultivo (galaxicultura), que se encuentra en etapa piloto.

Fish-Net: Probabilistic models for fishway planning, design and monitoring to support environmentally sustainable hydropower [PDF]
The construction of fishways for upstream and downstream connectivity is the preferred mitigation measure for hydropower dams and other riverine barriers. Yet empirical evidence for effective design criteria for many species is missing.

Preliminary investigation of systematics of some Tasmanian Galaxiidae
The investigation has revealed no Tasmanian galaxiid identical with any New Zealand form. The fish known hitherto as Galaxias attenuatus in Tasmania is shown to be at least subspecifically different from the form bearing this name in New Zealand. The two forms are referred to the species maculatus Jenyns on the grounds of page precedence, and are ...

Gorges partition diversity within New Zealand flathead Galaxias populations
Abstract Understanding the landscape factors governing population connectivity in riverine ecosystems represents an ongoing challenge for freshwater biologists. We used DNA sequence analysis to test the hypothesis that major geomorphological features underpin freshwater‐limited fish diversity in a tectonically dynamic region of New Zealand ...
