Seal hunting

Seal hunting is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Seal hunting rather than just read about it. In short: Seals are hunted in nine countries: Canada, Denmark (in self-governing Greenland only), Russia, the United States (above the Arctic Circle in Alaska), Namibia, Estonia, Norway, Finland and Sweden. Most of the world's seal hunting takes place in Canada and Greenland.

Key takeaways

Seal hunting belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Seal hunting to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Seal hunting from memory before moving on to harder problems.

Reference excerpt

Seals are hunted in nine countries: Canada, Denmark (in self-governing Greenland only), Russia, the United States (above the Arctic Circle in Alaska), Namibia, Estonia, Norway, Finland and Sweden. Most of the world's seal hunting takes place in Canada and Greenland. The Canadian Department of Fisheries and Oceans (DFO) regulates the seal hunt in Canada. It sets quotas in the form of a total allowable catch (TAC), monitors the hunt, studies the seal population, works with the Canadian Sealers' Association to train sealers on new regulations, and promotes sealing through its website and spokespeople. The DFO set harvest quotas of over 90,000 seals in 2007; 275,000 in 2008; 280,000 in 2009; and 330,000 in 2010. The actual kills in recent years have been less than the quotas: 82,800 in 2007; 217,800 in 2008; 72,400 in 2009; and 67,000 in 2010. In 2007, Norway reported that 29,000 harp seals were killed, Russia reported that 5,479 seals were killed and Greenland reported that 90,000 seals were killed in their respective seal hunts. Harp seal populations in the northwest Atlantic declined to approximately 2 million in the late 1960s as a result of Canada's annual kill rates, which averaged to over 291,000 from 1952 to 1970. Conservationists demanded reduced rates of killing and stronger regulations to avert the extinction of the harp seal. In 1971, the Canadian government responded by instituting a quota system. The system was competitive, with each boat catching as many seals as it could before the hunt closed, which the Department of Fisheries and Oceans did when they knew that year's quota had been reached. Because it was thought that the competitive element might cause sealers to cut corners, new regulations were introduced that limited the catch to 400 seals per day, and 2000 per boat total. A 2007 population survey conducted by the DFO estimated the population at 5.5 million. As of 2024, the population was estimated at 4.4 million seals, a notable decline since 2019 when the population was at an estimated 5.6 million. Under the revised Atlantic Seal Management Strategy, the estimated 2024 total abundance of Northwest Atlantic harp seals is considered to be in the "Cautious Zone", a classification based on an 80% probability that the population is currently below the Precautionary Reference point of 4.8 million seals. The decline in the harp seal population since 2019 suggests that recent environmental conditions, particularly sea ice availability, could be exerting a substantial influence. The Department of Fisheries and Oceans (DFO) acknowledges that future harvest projections assume consistent ice conditions, and that predicted environmental changes could lead to further population declines and lower sustainable harvest levels. In Greenland, hunting is done with a firearm (rifle or shotgun) and young are fully protected. This has caused some conflicts with other seal-hunting nations, as Greenlanders sometimes boycotted the product of seals (often young) killed by clubbing or similar methods, which have not been in use in Greenland. It is illegal in Canada to hunt newborn harp seals (whitecoats) and young hooded seals (bluebacks). When the seal pups begin to molt their downy white fur at the age of 12–14 days, they are called ragged-jacket and can be commercially hunted. After molting, the seals are called beaters, named for the way they beat the water with their flippers. The hunt remains highly controversial, attracting significant media coverage and protests each year. Images from past hunts have become iconic symbols for conservation, animal welfare, and animal rights advocates. In 2009, Russia banned the hunting of harp seals less than one year old.

Terminology The term seal is used to refer to a diverse group of animals. In science, they are grouped together in the pinnipeds, which also includes the walrus, not popularly thought of as a seal, and not considered here. The two main families of seals are the Otariidae (the eared seals; includes sea lions, and fur seals), and Phocidae (the earless seals); animals in the family Phocidae were sometimes referred to as hair seals, and are better adapted for a fully aquatic lifestyle than the eared seals, though they have a more difficult time getting around on land.

Uses The fur seal yields a valuable fur; the hair seal has no fur, but oil can be obtained from its fat and leather from its hide. Seals have been used for their pelts, their flesh, and their fat, which was often used as lamp fuel, lubricants, cooking oil, a constituent of soap, the liquid base for red ochre paint, and for processing materials such as leather and jute. Pinseal was fashioned into handbags, and seal livers were an early source of insulin. Early commercial sealers discarded most of the flesh, but might save seal hearts and flippers for an evening meal.

Worked examples

Example 1 — a first encounter with Seal hunting

Start with the simplest possible case. Write down what Seal hunting claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Seal hunting before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Seal hunting ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Seal hunting

In research: Seal hunting appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Seal hunting in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Seal hunting is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal culling, Animal rights, Cruelty to animals, so understanding it makes those chapters shorter.
In everyday life: Look for Seal hunting outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
