The Possible Role of the Guppy, Lebistes reticulatus, on the Biological Control of Schistosomiasis mansoni

Abstract

Snails (Australorbis glabratus) are common where guppies are found. The absence of guppies in certain aquatic regions in Puerto Rico may result from the fact that A. glabratus is also absent. The egg masses of the snail may constitute essential food for the guppy for which the fish may have predilection.
