Ecological Results
SealNet identified four individual seals that were photographed in both
2019 and 2020: 015_Armani, 198_Petal, 211_Clove, and 393_Cystine.
All four seals were originally photographed on Brandt Ledges in 2019 and
were re-photographed on Mitchell Fields (198_Petal and 211_Clove),
Whaleboat (393_Cystine), or Branning Ledges (015_Armani) during the
2020 season. Our mark-recapture estimate based on our total number of
seals photographed in both 2019 and 2020, with four individuals
“recaptured,” reveals an approximate initial population size estimate
of 4,386 individuals in the Middle Bay region of Casco Bay.
