Article Synopsis
- Heavy metal contamination in aquatic environments, particularly from anthropogenic activities, poses risks to fish and subsequently to consumers. This study focused on Barramundi fish from the northern Bay of Bengal, analyzing metal concentrations in their gills, liver, and muscle.
- Farmed Barramundi exhibited higher heavy metal levels in their liver compared to wild ones, with Zinc being the most concentrated metal across all examined organs, while lead (Pb) levels in farmed fish exceeded safety limits.
- Although the overall metal concentrations were below acceptable guidelines, the study highlighted liver as the primary accumulation site for heavy metals like Pb, Cu, and Cd, pointing to environmental and dietary factors influencing accumulation levels.
Freshwater fishes often exhibit high genetic population structure due to the prevalence of dispersal barriers (e.g., waterfalls) whereas population structure in diadromous fishes tends to be weaker and driven by natal homing behaviour and/or isolation by distance.

Mitochondrial DNA B Resour
September 2016
Complete mitochondrial genome sequences were determined for two lineages ("CEQ" and "SEQ") of the Australian smelt, . Both mitogenomes contain the typical vertebrate arrangement of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and control region. A conventional start codon for ND2 was not present in either lineage; instead CTG (Leucine) was present at this position.
