The totora reeds are a primary source of food. The Uru also make a reed flower tea. Local residents fish ispi, carachi and catfish. Trout was introduced to the lake from Canada in 1940, and kingfish was introduced from Argentina. Uru also hunt birds such as seagulls, ducks and flamingos, and graze their cattle on the islets. They also run crafts stalls aimed at the numerous tourists who visit ten of the islands each year. They barter totora reeds on the mainland in Puno to get products they need, such as quinoa and other foods. Domesticated animals The Uru people have domesticated local animals to assist with producing food and other purposes. For example, cormorants, waterbirds who catch fish, are kept tethered with wool tied to their feet, so that they can catch fish for human consumption. Another local bird, the ibis, is domesticated for laying eggs. Ibis are also butchered for meat. To control rats on the reed islands, domestic cats are also kept by the Uru islanders. Some islands also feature ponds inside the island; yet again some of these are lined with a large fishing net and suggest localised Aquaculture. The primary amount of fish is still caught in the wide open of Lake Titicaca. Modern life The Uru do not reject modern technology: most boats have motors, nearly all islands have shared solar panels to run appliances such as televisions and the main island is home to an Uru-run FM radio station, which plays music for several hours a day. High ultraviolet radiation levels occur throughout the Altiplano region of Peru and Bolivia. Kindergarten and elementary schooling is done on several islands, including a traditional school and a school run by a Christian church. Older children and university students attend school on the mainland, often in nearby Puno. Historically, most of the Uru islands were located near the middle of the lake, about 9 miles from the shore; however, in 1986, after a major storm devastated the islands, many Uru rebuilt closer to shore. , about 1,200 Uru lived on an archipelago of 60 artificial islands, clustering in the western corner of the lake near the port town of Puno. The islands have become one of Peru's tourist attractions, allowing the Uru to supplement their hunting and fishing by conveying visitors to the islands by motorboat and selling handicrafts.
