Seal Fishery
Background: History, Resource and Natural Environment
Historical Setting
In areas where renewable resources were scarce or uncertain, widely
separated, and accessible only seasonally, settlers developed strategies
geared to the exploitation of these resources throughout the year. The
utilization pattern was normally woven into a seasonal round of activities.

Under ideal conditions, each exploited resource complemented the others
throughout the year. In the northern parts of Newfoundland there was usually
a period of relative inactivity in spring, after woodswork had ceased and
before the first appearance of the cod stocks. For settlers moving into
the harbours and coves of coastal Labrador and northeastern Newfoundland
during the 18th and 19th centuries, however, this period
often became a time of intensive and commercially rewarding activity.
By late winter and early spring, this coast was blockaded by local and arctic
ice in most years, and with the ice came harp seals.

The seals appeared for one to two weeks in late December and January as the
herds migrated southwards from the Arctic, and again in late February and
early March as they swam northward to give birth on the drifting pack-ice.

Pioneer settlers in the more northerly parts of Newfoundland
quickly discovered that migrating harp seals could be caught in nets attached
to shore as they swam south; this was called the landsmen seal fishery.
Later, towards the end of the 18th century, the patches of
whelped whitecoats became the focus of an annual spring seal
hunt carried on in larger vessels. Seals constituted an additional and welcomed
resource during a commercially quiet period in the traditional annual round.

The Newfoundland and Labrador seal fishery evolved through overlapping
phases. Each phase was characterized by the acceptance of new technology, which
brought with it new strategies, techniques, and changes in patterns of financial
investment and ownership. The number of sealers declined and different regions
became involved.
In spite of new technology and other changes, catches of seals declined, and
until recently, there were reductions in this resource base.
Every major infusion of technology was primarily associated with
the sealers' desire to improve their abilities to cope with the obstacles
encountered when attempting to gain access to the seals. To understand
the Newfoundland seal fishery, therefore, it is necessary to examine the
main characteristics of the resource; and of the environment to which it
has adapted, and into which the sealer must intrude.
The Resource
The sealing industry developed in response to the abundance of sea mammals
that frequent Newfoundland and Labrador inshore waters. The very nature of the
venture has been strongly influenced by the habits and character of the seals.
Although hood seals have sometimes been harvested, the harp has been the mainstay
of the sealing industry. Pregnant harp females in the western Atlantic
herd swim northward in February in search of suitable birthing ice. They
form large groups and give birth at approximately the same time each year,
so the young seals (whitecoats) are born in close proximity to one another,
forming
whelping patches that often cover several square kilometers of ice.

The harp pup loses its coat of white downy hair within three weeks.
Known then as a "ragged-jacket," and finally, in its first year
as a "beater," the young harp in the process of becoming an adult
seal (mature, saddleback, harp) is called a "turning seal" (turner),
"immature," or "bedlamer" (bête de la mer). Sexually
mature at approximately four years, adult seals have an average life span
of over 20 years.
Initially harps of all ages were caught by landsmen. However, the whitecoat
and moulting (shedding of winter coats) patches became the principal targets
of the offshore sealing fleet. Although more vulnerable at this time than
at any other stage in their life cycle, these seal herds were given some
degree of protection by the hazardous environment, and the hunters' limited
ability to navigate the icefloes.
The Natural Environment
Of all the environmental factors that affect the harvesting of harp
and hood seals during late winter and early spring, the most important
is the quantity and condition of sea-ice.

The relative importance of other environmental factors is determined
by their influence on the growth, distribution and character of these protective
ice-fields.

The seasonal formation and movement of sea-ice off southern Labrador
and northeastern Newfoundland (the "front") is generally away
from the land toward the south and the southeast. This occurs in response
to the general southward flow of the Labrador Current and the prevalence
of offshore westerly winds.

While varying greatly from year to year, the total area of the whelping
and moulting patches has always been extensive. The normal pattern of seasonal
growth, and the degree of variation in the location of pack-ice within the
same year, has also been wide-ranging. Annual variations occur as a result of temperatures,
ocean currents and prevailing winds. Within each season, however, the largest
single determinant of the relative day-to-day configuration of the ice-floes
is the strength, duration and direction of winds.
The presence of offshore pack-ice during the early spring, then, provided
many coastal settlements on the headlands and outer islands with relatively
easy access to a rich resource and a temporary surface on which to hunt.
This practice, however, also involved difficulties and hazards in navigating
vessels and harvesting the seals. If they wished to be successful, or even
to survive, sealers had to adapt to the dangers posed by wind, sea and
ice. Much depended on their knowledge and experience, and to a large extent
upon the technology at their disposal.
