Latin American Journal of Aquatic Research, 2008 The nuclear DNA content (2C value) was determined in the commercial fish Galaxias maculatus (Galaxiidae) was determined by microdensitometry of erythrocyte nuclei after Feulgen staining; rainbow trout erythrocytes with a known 2C value were used as a ...

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 ...

Group swimming significantly decreases time to passage success for a galaxiid species. [PDF]
J Fish BiolAbstract We conducted laboratory experiments to explore the potential benefits of group behaviour on passage performance for a small‐bodied migratory species, inanga Galaxias maculatus. An artificial velocity barrier was created to compare the fish passage success of groups of fish to solitary individuals.

Acute toxicity of ammonia to juvenile inanga (Galaxias maculatus) [PDF]
New Zealand Journal of Marine and Freshwater Research, 1991 Abstract The toxic concentration of unionised ammonia (NH3) was assessed for juvenile Galaxias maculatus by running a 96 h LC50 test. The 96 h LC50 concentration at 15°C and pH ≥ 8 was 1.60 mg NH3 1−1, with a 95% confidence limit of 1.47–1.73 mg NH3 1−1. This is intermediate compared to toxic concentrations reported for other freshwater fish species.

Deposition of Galaxias fasciatus eggs with Galaxias maculatus eggs at a tidal site [PDF]
New Zealand Journal of Marine and Freshwater Research, 1991 Abstract 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 at 300 mm above normal water level. The two sizes of eggs were distributed differently along

Interactive Effects of Copper Contamination and Salinization Across Multiple Genotypes of <i>Daphnia magna</i>. [PDF]
Ecol EvolThis study examined how Daphnia magna genotypes from US and French populations respond to copper and salinity stress, alone and in combination. US genotypes were generally more sensitive but showed improved survival under combined stress, indicating possible cross‐tolerance mechanisms.

A Tasmanian landlocked population of the normally diadromous fish Galaxias maculatus (Jenyns) [PDF]
Papers and Proceedings of The Royal Society of Tasmania, 1982 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 other species together with the probable mode of origin of the landlocked population are ...

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 ...

Assessing Patterns and Risk to Chilean Freshwater Fish Distributions Using Multi-Species Occupancy Models. [PDF]
Ecol EvolTo advance our understanding of freshwater biodiversity in data‐limited systems, this study used multispecies occupancy models to predict species richness and individual species occupancy, providing critical insights for the conservation of these rapidly declining ecosystems.
