Examination of Riviere Lislet Les Cayes Haiti

The short study of Riviere Glace was followed by a brief examination of Riviere Lislet that runs south along the eastern edge of Les Cayes before ending at the ocean.  We sampled where Rue Simon crosses the river, and arrived before the area was too busy with people washing themselves, laundry, and motos.  The water was warmer and siltier than Riviere Glace, but we found a lot of the native mosquito fish (Gambusia) and small tilapia (non-native fish).  The young men there were very eager to help us find fish and macroinvertebrates.
