To maximize individual recognition reliability, we analyzed photographs of whales with 2+ notches in the dorsal fin, or with dorsals exhibiting unique scarring and/or deformation. Results demonstrated variation in annual marking rates of 8%-13%, with intra-annual recaptures of individuals spanning up to 104 days. Twelve individuals were recaptured in multiple years, and one whale was recaptured in 6 years. Despite a limited sample size (n=35), the proportion of whales recaptured suggests some site-fidelity in the study area. Results from biopsy analyses using 20 microsatellites indicated 6 intra- and 10 inter-annual recaptures. One recapture between 3 pairs of consecutive years was not sufficient for an abundance estimate yet this low number suggests a conservative population estimate of 200+ whales in the region. Moreover, 155 of 180 (86%) individuals were female. No calves were observed during the study period, suggesting that they wean before summer or that lactating females segregate from other females. Our collective results support whaling data indicating that minke whales may be the only rorqual (Balaenopteridae) exhibiting sex segregation during summer.
