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.

Biological bases for whitebait culture Galaxias maculatus (Jenyns, 1842): a review
Latin American Journal of Aquatic Research, 2017 Galaxias maculatus (Jenyns, 1842), is a gourmet fish of great commercial importance with overexploited fisheries. So, studies of its biology are essential in order to develop a technology for its cultivation (galaxiculture), which is at a pilot stage. The goals of this work are: 1) to provide a synthesis of the literature information on the biology of ...

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

An Updating of Withebait Farming (Galaxias maculatus) in Chile [PDF]
, 2012 The withebait Galaxias maculatus is an endemic species from Argentina and Chile (Cussac et al., 2004), and it is important in ecological webs in Argentinean and Chilean inland waters (Soto & Zuniga, 1991; Soto et al., 1994; Modenutti et al., 1998). This species has a maximum size of 17 cm and its migratory juvenile stage is transparent or “crystalline”

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.
