The killing of seals, marine mammals belonging to the order Pinnipedia, occurs across various coastal and Arctic regions globally. This activity is frequently a subject of intense international debate, involving complex interactions between economic interests, cultural traditions, and animal welfare concerns. Understanding the reasons requires examining diverse motivations, ranging from large-scale commercial operations driven by market demand to localized actions focused on resource protection or cultural survival.
Economic Motivations for Commercial Harvesting
The largest-scale killing of seals is driven by commercial demand for animal products, primarily conducted in the North Atlantic, particularly in Canada and Greenland. This industrialized harvest focuses heavily on species like the harp seal. The financial incentive centers on obtaining three main products: pelts, oil, and meat, though their market value fluctuates significantly. The primary product driving the commercial hunt is the pelt, used to produce fur garments and accessories.
Demand for seal fur has been volatile. International regulations and trade bans, such as the 2009 European Union ban on seal products, caused dramatic reductions in market value and harvest activity. These regulatory shifts removed a major export market, forcing the industry to seek alternative buyers in Far Eastern and domestic markets.
Seal oil, extracted from the blubber, represents the second major commercial product, marketed for industrial applications and nutritional supplements. Harp seal oil is valued as a source of Omega-3 fatty acids, including docosapentaenoic acid (DPA). Meat is processed for human consumption or rendered into animal feed. However, the market for meat has been weak in some commercial contexts, leading to instances where non-pelt portions are not fully utilized.
Seals as Competitors to Commercial Fisheries
Conflict between seals and commercial fishers is a significant, localized motivation for killing the animals, driven by the protection of human livelihood. This conflict involves two categories: indirect competition for shared fish stocks and direct interaction resulting in property damage. Fishers often perceive seals as direct competitors for valuable commercial species, such as cod, salmon, and herring.
The perception of seals depleting fish stocks often leads to calls for culls to increase the commercial catch. Scientific evidence frequently indicates that the decline in fish populations is more directly linked to factors like overfishing and environmental changes. The tangible conflict involves direct depredation, where seals remove or damage fish already caught in fixed fishing gear like nets or traps.
This interaction causes measurable economic losses for fishers in areas like the Baltic Sea and along the coast of New England. Seals can also cause extensive damage to the gear itself, requiring costly repairs or replacement of nets. Their presence around fishing areas can indirectly reduce catches by scaring away schools of fish. These economic harms compel some fishers to take localized action against the animals to protect their property and income.
Traditional and Subsistence Hunting Practices
Distinct from large-scale commercial operations are the traditional and subsistence hunting practices of Indigenous and coastal communities, carried out for thousands of years. For groups such as the Inuit across the Arctic, seals are an integral part of their diet, providing nutrient-dense meat and blubber. The hunt focuses on survival and meeting basic community needs, not generating profit. Pelts are utilized for warm clothing and tools, while the oil can be used for fuel and light.
This practice is deeply entwined with the cultural identity and heritage of these communities, serving as a means of passing down traditional knowledge. Products derived from these Indigenous subsistence hunts are granted specific exemptions from trade bans that apply to commercially harvested seal products.
These traditional hunts are generally regulated separately from commercial quotas and prioritize full utilization of the animal. The species hunted often includes ringed seals and bearded seals. The continued practice offers a source of food security and cultural continuity.
Population Management and Conservation Culling
The authorized killing of seals is implemented by governments for ecological or public health reasons, falling under population management. One goal is to mitigate the local impacts of a growing seal population on specific, vulnerable resources or ecosystems. Culls have been considered to protect declining populations of commercially significant prey species, such as salmon or groundfish stocks.
Management culling has also been proposed to prevent seals from overpopulating breeding grounds or haul-out sites, which could strain local food availability or damage habitat. These efforts are typically authorized under specific legislation and serve a scientific or conservation objective. Localized culling is sometimes undertaken to control the spread of disease or to address public safety concerns.
