Fish samples of Champsocephalus gunnari and Notothenia rossii (tissues preserved in ethanol, and otoliths) were collected aboard the James Clark Ross (JR145) during the 2005-2006 field season. Morphometric data, including body length, mass, sex and reproductive condition, were derived from the samples.
Between 60-100 adult individuals of each species were collected from each of several locations including: Elephant Island, Deception Island and the South Orkney Islands. Sampling from these regions allows us to test the influence of local hydrology/currents around the Antarctic Peninsula as well as that of larger systems within the Scotia Sea (via comparisons with samples already collected from Shag Rocks and South Georgia).
