Little is known about the threat of mercury (Hg) to consumers in food webs of Australia's wet-dry tropics. This is despite high concentrations in similar biomes elsewhere and a recent history of gold mining that could lead to a high degree of exposure for biota. We analysed Hg in water, sediments, invertebrates and fishes in rivers and estuaries of north Queensland, Australia to determine its a...

Centropomidae as defined by Greenwood (1976) is composed of three genera: Centropomus, Lates, and Psammoperca. But composition and monophyly of this family have been challenged in subsequent morphological studies. In some classifications, Ambassis, Siniperca and Glaucosoma were added to the Centropomidae. In other studies, Lates+Psammoperca were excluded, restricting the family to Centropomus. ...

Barramundi (Lates calcarifer), a catadromous teleost of significant and growing commercial importance, are reported to have limited fatty acid bioconversion capability, typical of marine species, and therefore require preformed long-chain polyunsaturated fatty acids (LC-PUFA) as dietary essential fatty acid (EFA). In this study, the response of juvenile barramundi (47.0 g/fish initial weight) f...

To comply with the relevant legal requirements and correct labelling, it is necessary for business operators and inspection authorities to know the natural characteristics of the raw material. This study gives a comprehensive overview of muscle flesh composition of farmed and wild Atlantic turbot (Scophthalmus maximus) and barramundi (Lates calcarifer) and of farmed pangasius (Pangasianodon hyp...

Barramundi (Lates calcarifer) is an important Queensland commercial fishery that exhibits dramatic inter-annual fluctuations in catch which, according to fishers, are explained in part by variations in the climate. Traditionally, modelling of fisheries harvest has focussed on the development of surplus production/yield models which use catch and effort data, and more complex age-structured mode...
