Using scales to clarify the transition from blue-phase to brown-phase fingerling in Notothenia rossii from the South Shetland Islands
Scales and whole otoliths were read for age determination in early stages of Notothenia rossii caught in Potter Cove, South Shetland Islands, in summer seasons 2003-2006 and 2008. The sample comprised blue-phase pelagic fingerlings of 7.0-7.6 cm (TL) of age group 0 year and demersal brown-phase fing...
