Constraints upon the response of fish and crayfish to environmental flow releases in a regulated headwater stream network. [PDF]
PLoS ONE, 2014 In dry climate zones, headwater streams are often regulated for water extraction causing intermittency in perennial streams and prolonged drying in intermittent streams.

A Global Assessment of Parasite Diversity in Galaxiid Fishes
Diversity, 2021 Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowledge.

Journal of Fish Biology, Volume 109, Issue 1, Page 201-209, July 2026.Abstract Fish must manage the competing demands of ion balance and gas exchange across the gills – a physiological tension known as the osmorespiratory compromise. In dynamic estuarine environments, the osmorespiratory compromise may be exacerbated by variable salinity and periods of hypoxia that demand high respiratory work.

Frontiers in Marine Science, 2015 A relationship between life histories and increasing latitude has been described for Northern Hemisphere riverine fish, whereby life cycles that complete most of the growth in the ocean are favoured at higher latitudes.

Deposition of Galaxias fasciatus eggs with Galaxias maculatus eggs at a tidal site [PDF]
New Zealand Journal of Marine and Freshwater Research, 1991 While measuring egg distribution of the intertidally spawning galaxiid fish, Galaxias maculatus , some noticeably larger eggs (1.86–2.2 mm diam.) were seen. In common with the smaller G. maculatus eggs (1.18–1.5 mm diam.), these eggs peaked in abundance
