Habitat-use strategies of young barramundi (Lates calcarifer) in a heavily modified landscape. [PDF]
J Fish BiolAbstract Barramundi (Lates calcarifer) is a facultatively catadromous species that migrates between saltwater and fresh water to complete its life cycle. Modified riverine landscapes may limit these migratory paths and alter the environmental cues that migratory fish rely on to trigger migration.

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 ...

Interactions Between Non-Native Western Mosquitofish and Native Bluegill Sunfish: Mesocosm Experiments. [PDF]
Ecol EvolNative Bluegill Sunfish had important competitive impacts on invasive Western Mosquitofish and also had intraguild predation effects that prevented successful recruitment of Western Mosquitofish. In contrast, Bluegill Sunfish were affected by intraspecific effects more than by interspecific effects from Western Mosquitofish.

Distribution of the spotted minnow (Galaxias maculatus (Jenyns, 1842)) (Teleostei: Galaxiidae) in Western Australia including range extensions and sympatric species [PDF]
, 2006 Galaxias maculatus was captured from a number of rivers outside its previously known range. In Western Australia, it was formerly only known from rivers and lakes between the Goodga River (Two People's Bay, 30 km east of Albany) and the Dailey River (50 ...

Attraction of migratory inanga (galaxias maculatus) and koaro (galaxias brevipinnis) juveniles to adult galaxiid odours [PDF]
, 2003 The response of migratory galaxiid juveniles, inanga (Galaxias maculatus) and koaro (G. brevipinnis), to the odours of adult galaxiids was tested in a two-choice chamber apparatus. Both conspecific and heterospecific odours were tested. Inanga juveniles

Influence of open and closed river systems on the migrations of two northern New Zealand populations of banded kokopu (Galaxias fasciatus) [PDF]
, 2012 Otolith microchemical analysis by laser ablation inductively coupled mass spectrometry (ICP-MS) was used to investigate the migratory life histories of banded kokopu (Galaxias fasciatus) in two streams on the North Island of New Zealand.
