Occasionally fishermen suggest that seals should be culled and that this will increase fish stocks and there will then be more available for human consumption. However, closer examination of seal-fishery interactions at the ecosystem level suggests that removing or culling seals may in fact be detrimental to fish stocks rather than beneficial.
The UK is home to about 120,000 grey seals - roughly 40% of the world's population. While common seals give birth in June and July, the pupping season for grey seals coincides with the start of ...
The seals can live for as many as 30 years in the wild, while dealing with predators like orcas and larger leopard seals. They survive on fish, squid, and other smaller prey to survive.
The common smooth-hound comes close to shore in the late summer to breed, but is too small to be dangerous to humans. [6] The hammerhead shark (Sphyrna zygaena) is another fish eater, and is sometimes encountered while fishing.
Four seal species are estimated to have over one million members, while six are classified as endangered with population counts as low as 600, and two, the Caribbean monk seal and the Japanese sea lion, went extinct in the 20th century.
Harbor seals stick to familiar resting spots, generally rocky areas where land predators can't reach them, near a steady supply of fish to eat. Their global population is 400,000 to 500,000, and subspecies in certain habitats are threatened. Seal hunting, once a common practice, is now mostly illegal.
