Unpacking the complexity of longitudinal movement and recruitment patterns of facultative amphidromous fish [PDF]
Scientific Reports, 2022 Longitudinal movement plays fundamental role in habitat colonization and population establishment of many riverine fish species. Movement patterns of amphidromous fish species at fine-scales that would allow characterizing the direction of movement and ...

Cryptic diversity within two widespread diadromous freshwater fishes (Teleostei: Galaxiidae) [PDF]
Ecology and EvolutionIdentification of taxonomically cryptic species is essential for the effective conservation of biodiversity. Freshwater‐limited organisms tend to be genetically isolated by drainage boundaries, and thus may be expected to show substantial cryptic ...

Cultivation of whitebait (Galaxias maculatus) in Chile [PDF]
Aquaculture Research, 2008 The growth of commercial aquaculture in Chile generated an income of $2.300 million USD in exports in 2005. Currently, 15 different species are cultivated commercially, of which seven are native; these had returns of 185 million USD. Among these native species is Galaxias maculatus (whitebait), which is endemic to Chile and figures significantly in ...

New Zealand Journal of Marine and Freshwater Research, 2023 ABSTRACT The common occurrence of dams is a major threat to riverine fish communities globally and a common remediation technique for fragmented fish communities is fishway construction. Demonstrating the effectiveness of this technique on impacted species is required to rationalise or improve management practices.

Teaching fish new tricks: Repeated exposure to a velocity barrier improves passage performance. [PDF]
PLoS ONEInstream structures like culverts and dams can impede upstream fish migration, acting as environmental filters that only allow onward migration of individuals that can successfully pass them.

Helminth parasitism of Galaxias maculatus (Jenyns 1842) in southwestern Australia [PDF]
Ecology of Freshwater Fish, 2006 Abstract – One cestode, Ligula sp. [possibly Ligula intestinalis (L.)], one trematode, Diplostomum sp., and two nematode parasitic worms, Eustrongylides sp. [possibly Eustrongylides gadopsis (Royal Society of South Australia, 64, 340)] and Contracaecum sp.

Otolith microchemistry and diadromy in Patagonian river fishes [PDF]
PeerJ, 2019 Coastal habitats in Chile are hypothesized to support a number of diadromous fish species. The objective of this study was to document migratory life histories of native galaxiids and introduced salmonids from a wide latitudinal range in Chilean ...

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.

Development of a Trait-Based Risk Assessment to Minimise the Impacts of Trout on New Zealand Native Fishes. [PDF]
Ecol EvolA trait‐based risk assessment framework was developed to identify New Zealand's native freshwater fish most vulnerable to the pressures of valued sports fisheries (trout). We further examine where the distributions between at‐risk species and trout are likely to overlap, providing priority locations for conservation managers to investigate further and ...
