How were harp seals hunted?
Harp seals were hunted both on the ice and from shore. Sdobnikov (1933, in Sergeant 1991) described a spring net fishery for harp seals, which took place at that time on the Murman coast. Seals were also hunted from shore on both coasts and around the Kanin Peninsula, and later in the season from boats (Sergeant 1991).
How long is the gestation period of a harp seal?
Although mating occurs shortly after the pups are weaned, harp seals undergo embryonic diapause (delayed implantation) for 3-4 months with implantation occurring in late July or early August (Stenson et al. 2016, Stewart et al. 1989). This results in the gestation period lasting almost a full year.
