Fish Ecology in Our Local Rivers

The research activities of Lehman's Laboratory for Marine and Estuarine Research (La MER) have focused on studying the aquatic environments of the Bronx, Saw Mill and East Rivers. Under the leadership of Joseph Rachlin, Professor of Biological Sciences, researchers have analyzed the community structures of both marine and freshwater fish species. Professor Rachlin and his team have also discovered and were the first to publish on the arrival of a non-native species of shrimp Palaemon macrodactylus (the oriental shrimp) to our coastal waters. La MER researchers continue to monitor this visitor to assess its impact on the native shrimp populations in our waters.
