Inventaire de la faune ichtyologique de l'Indochine: deuxième liste

In 1926, The Oceanographic Institute published a first list of Indochinese fish, prepared by Mr. P. Charanaud. This first inventory included 275 species. For 6 years, researches conducted by the Oceanographic Institute, both at sea and on major rivers and lakes in the South of Vietnam, have contributed to build a collection of 4,000 individuals at least. Its inventory and the development of a huge documentation allowed the publication of the present note that includes 375 species.
