Lake Superior Kiyi scale and otolith age estimates in 2014 with Kiyi sampling locations from 2003-2014

July 8, 2019

Age estimates of Lake Superior Kiyi (Coregonus kiyi) from scales and otoliths were compared from fish collected in 2014 and 12 years (2003 to 2014) of length frequency data were examined to assess year-class strength and validate age estimates. Data were obtained to (1) compare Lake Superior Kiyi ages estimated from scales and otoliths, (2) evaluate variability in year-class strength of Kiyis, and (3) assess the validity of otolith-derived Kiyi ages by comparing the distribution of age estimates to strong year-classes identified from annual length frequency distributions.
