Seal culling: for conservation or clothing?


Animal rights activists are up in arms over a proposed seal culling campaign that the Angolan government claims is necessary for fish conservation. While supporters claim that seal populations must be controlled in order for fishermen to survive, opponents argue that the people in charge really want to expand the business of selling seal skins and other products.

Angola has a large grey seal - not sea lion-  population, estimated at 27,500 in 2012. And it’s growing fast. From 2006 to 2012, seal numbers grew 14%. Each seal eats between 8kg and 30kg of fish every day, and Angolan fishermen claim that the marine carnivores are having a detrimental effect on fisheries.

Knowing that, a well-managed cull makes some sense. The process of culling is stressful and pretty horrific for the animals. Nursing pups are taken away from their mothers and clubbed to death. And, as the director of the seal campaign at the International Fund for Animal Welfare claims, no scientific study has ever shown a seal cull to have a beneficial effect on fish stocks. Additionally, removing predators like the seal could have unexpected effects on sensitive ecosystems and would have to be handled very cautiously.

Activists claim that politicians may want to expand the seal products business. Asian markets sell products like seal genitalia, but the European Union bans all seal products, including skins. The ministry of the environment, which proposed the culling program, claims that it is just one proposed possibility to help fishermen and that it is exploring other options. Hopefully Angola will find another solution to help fishermen and will realize that it is rich enough in other resources that it does not need a seal products economy.

Procavia capensis spotting!

What's round and furry and brown all over?

Why, a hyrax of course!

Commonly known as dassies, hyraxes (hyrax-i?) are a permanent fixture on Table Mountain.

Today, I--along with four other lovely ladies from the house--took the big step of climbing up Table Mountain, one of the New Seven Wonders of the World!*  It was, breathtaking. So beautiful and magnificent. The flora at the top of the mountain was extremely diverse, ranging from the Climber's friend, or Cliffortia ruscifolia, to the Wagon tree, or the protea nitida.

Most importantly... we found this little guy up at the top just nibbling away at some plants--their diet consists primarily of grass and leafy plants, but can also eat insects and grub--and hopping around from rock to rock:

While rock hyraxes are supposed to extremely sociable and vocal critters, they were not really in the mood for talking today. Unfortunately, we did not to get to hear any of the 21 different vocal signals that they are known to produce including a high trill that is made when hyraxes feel threatened. A hyraxes "song" (as these vocalizations are called)  can vary by geography and scientists have found that there there exists some kind of a syntactic structure. Most importantly, scientists have discovered that the variety in the hyraxes song can reveal characterizing information.
