Catch-at-age of northwest Atlantic harp seals / G.B. Stenson, B. Sjare and D. Wakeham. : Fs70-1/1999-105E-PDF
This report summarises available harp seal catch and catch-at-age statistics from 1952 to 1998 for southern Labrador and the northeast coast of Newfoundland ('the Front"), in the Gulf of St. Lawrence ('the Gulf'), along west and southeast Greenland, and the eastern Canadian Arctic. Catches at the Front and in the Gulf decreased after 1982 and remained low (less than 65,000 for most years) until 1995. Annual catches increased significantly to over 240,000 between 1996 and 1998. Catches in Greenland have increased significantly in recent years to approximately 84,000. Catches in the Canadian Arctic are considered to be relatively small. The age composition of catches at the Front and in the Gulf were estimated based on reported numbers of young taken and biological samples of seals one year of age and older taken from the commercial harvest and research samples. Estimates of the age composition of seals harvested in Greenland were obtained from biological samples collected in West Greenland between 1970 and 1993.
