Biological data from cod collected in 2003, 2004 and 2005 from Ogac, Qasigialiminiq and Tariujarusiq Lakes on Baffin Island, Nunavut, Canada. Cod were collected by hook-and-line, gill net and minnow trap. Data include sex, maturity, length, round weight, dressed weight, liver weight, gonad weight, age and age estimate confidence score.
