Three Fish Varieties Found in Tibetan Highland Lake, Paper Says

[WTN-L World Tibet Network News. Published by The Canada Tibet Committee. Issue ID: 01/04/13; April 13, 2001.]

TOKYO April 13 Kyodo - Researchers from China and Japan have confirmed the existence of three varieties of fish in Puma Yumco, a lake 5,000 meters above sea level in Tibet, and a nearby river, the first report of fish at such a high altitude, a Japanese newspaper reported Friday.

One of the three is thought to be a variant of the nude fish commonly found throughout China, which look like loach and grow to a little over 10 centimeters, the Yomiuri Shimbun said. The light-brown fish have six barbels but no scales, it said.

The two others are species that look like trout, with slight differences between those found in the lake and those found in a river that flows out of the lake, the paper said.

The researchers, including specialists from Japan's Tokai University and the Chinese Academy of Sciences, found a dead fish measuring 27 cm, and smaller live ones in the lake. The similar kind of fish caught in the river measured up to 21 cm, according to the paper.

It remains a mystery as to what these fish, measuring 20 cm or more, feed on, as the region is barren in terms of vegetation, the paper said. It could be that water melted from snow on the mountains around could be bringing nutrients to them, it said.
