In Greenlandic waters the harbour porpoise (Phocoena phocoena) has bee
n observed around the southern part of Greenland from Ammassalik on th
e east coast to Avanersuaq in northwest Greenland. The main distributi
on lies between Sisimiut and Paamiut in central west Greenland. Catch
statistics from 1900 to 1993 indicate an annual average take of 668 ha
rbour porpoises, ranging from 27 to 1531 animals. A decline in the rep
orted catch has been recorded since 1980. Harbour porpoises are mainly
caught between April and November, with a peak during June to October
. Five fish species, crustaceans and squids have been found in stomach
contents of harbour porpoises in Greenlandic waters. There are no ind
ications that environmental issues such as organochlorines, heavy meta
ls, oil or noise have constituted any threat to harbour porpoises in G
reenland. No reports of ice entrapments of harbour porpoises have yet
been made in Greenland, as is the case for white whales and narwhals o
n the west coast of Greenland. Disease patterns of harbour porpoise ha
ve not been studied in Greenland and incidents of mass mortality have
never been recorded. Killer whales are sparse along the west Greenland
coast and are not believed to constitute a threat to the harbour porp
oise population. In Greenland no estimates on stock size are available
, and a monitoring programme is needed if the impact of the catch is t
o be evaluated.
