Data show length (cm) and weight (g) of Trematomus bernacchii from four sites along a gradient south in the direction of the current from the Davis Station wastewater outfall (Outfall (0km); Torkler Rocks (1km); Warriner Island (4km) and Kazak Island (9km)) and two reference sites north of the outfall (Long Fjord (9kmN) and Bandits Hut (16km N). Fish were collected in the summer of 2012/13 using line and box traps. Fish were transported immediately back to the lab for analysis.

Gross body measurements of fish length (cm), weight (g), and sex (M/F). Fish were collected on line and in box traps at Brown Bay, Shannon Bay, near Wilkes Station, O'Brien Bay and Sparkes Bay. Sex was determined after dissection for other analyses.

Data show results of carbon and nitrogen stable isotopes in muscle tissue of Trematomus bernacchii collected at 5 sites adjacent to Casey Station. Sites are contaminated Brown Bay, near Wilkes Station, Shannon Bay and reference O'Brien Bay and Sparkes Bay. Approximately 1cm3 of muscle tissue from the left side of each fish was taken for stable isotopes analysis.
