A wildlife organization on Tuesday announced that they have discovered 12 species of freshwater fish new to Vietnam, local news website VnExpress reported.
A study done in the southern province of Kien Giang's Phu Quoc Island since the end of 2008 had found the new species, it quoted the report of Wildlife At Risk (WAR) organization as saying.
Bui Huu Manh from WAR said the findings showed that many species of freshwater fish are likely yet to be discovered.
The species help scientists observe changes in fish population that can provide the basis for preservation and conservation strategies, he said.
The latest report of the United Nations Environment Program shows that freshwater fish play an important role in maintaining ecological balance and are a source of food for millions of people all over the world.
However, in many countries, the population of many species are decreasing because of water pollution or loss of habitat.
