Exotic pets USA: Tigers, big bucks and organised crime

February 9th, 2012

The story of the man who released his 56 exotic animals into Ohio farmland and then took his own life has brought US animal ownership laws to the attention of the world. Here we take a look at what it really takes to get an exotic pet into an American home.

What types of exotic animal can you own in the US?
Eight states have no laws at all governing the ownership of exotic animals. Elsewhere, dangerous beasts from bears to primates to crocodiles are allowed as pets in much of the country. But even in states with ownership laws, the types of animals allowed vary widely. Arkansas, for example, has a ban on owning large carnivores like lions, tigers and bears, but each citizen can own up to six bobcats. Similarly lax laws in Colorado allow for ownership of up to six kangaroos.

These lenient rules don’t come without consequences. The Exotic Animal Incidents database compiled by animal protection organisation Born Free USA cites 75 human deaths since 1990 and over 1500 other incidents. Most occurred in Florida.

How many exotic animals are privately owned in the US?
There are no good numbers because there are no federal regulations on animal ownership, and each state keeps records separately. Leigh Henry is a US-based tiger expert at the conservation campaign group WWF and says, “There’s no way to know at any given time where they are.” WWF estimated in 2004 that about 5000 tigers were kept in captivity in the US and only 5 per cent of those were in accredited zoos. » Read more: Exotic pets USA: Tigers, big bucks and organised crime

Dolphin increasingly on the menu in poor countries

February 8th, 2012

FLIPPER for dinner? It’s more common than you might think. Though eating sea mammals is frowned upon in much of the world, the consumption of animals such as whales, dolphins and manatees is on the rise in poor nations. Declines in coastal fish catches have led people to look for other sources of meat.

“This is essentially a bushmeat problem,” says Martin Robards of the Wildlife Conservation Society in Alaska. Robards worked with Randall Reeves of the Okapi Wildlife Associates in Quebec, Canada, to compile the first comprehensive report of the types and numbers of marine mammals consumed each year. Their review of some 900 sources found that large-scale whaling has decreased in the last four decades, but that doesn’t mean marine mammals are out of danger.

Smaller cetaceans are making their way to dinner plates as other protein sources are dwindling in coastal areas of west Africa, Peru, Brazil, Colombia, Trinidad and Tobago, Madagascar, Sri Lanka, India, the Philippines and Burma. From 1970 to 2009, at least 92 species of cetaceans were eaten by humans (Biological Conservation, DOI: 10.1016/j.biocon.2011.07.034).

“Traditionally, you think of Japan or natives in the Arctic as big consumers, and they are,” says Robards, “but that’s not the whole story.” The rise in consumption can also be attributed to more unintentional kills as fishing nets improve and by-catch animals fail to escape.

Live updates from fishing boats could reduce waste

When customers of the fisheries company Sanriku Toretate Ichiba want to shop for fish, they connect to the net. The firm, based in Sanriku town in Japan’s Iwate prefecture, posts details of its catches online in real time, offering consumers the chance to buy fish almost as soon as it is hauled from the sea. This could help make fishing more sustainable by matching supply and demand, says the entrepreneur behind the firm – though others are unconvinced.

Kenichiro Yagi set up his online fisheries company in 2010. Events since then have made the move seem prescient. Sanriku was devastated by last year’s tsunami. Iwate lost 108 of its 111 ports and over 9000 fishing vessels, leaving fishermen without the tools to catch fish or a place to sell it.

Total financial losses for the agriculture and fisheries industries as a result of the tsunami are estimated at ¥2 trillion ($26 billion), according to Tetsuo Morimoto, parliamentary secretary of the Ministry of Agriculture, Forestry and Fisheries.

“Real recovery in the region cannot be achieved without recovery of the food industry,” he told Japan’s annual Food Industry Summit in Sendai, one of the regions affected by the tsunami, last November. “We will do whatever we can to rehabilitate the food industry in the region.”

Boats with webcams

Yagi decided not to wait for government help. Within a month of the disaster his company was trading again. His team managed to salvage four boats and equipped them with webcams and laptop computers, for the purpose of putting details of catches online. » Read more: Live updates from fishing boats could reduce waste
