Dynamics of shrimp fauna in the Aby-Tendo-Ehy Lagoon complex (southeast of Côte d'Ivoire), an hydrosystem under anthropic pressure

In order to provide basic scientific data essential for the conservation and sustainable management of the Aby-Tendo-Ehy Lagoon complex in South East of Côte d’Ivoire, patterns of shrimps’ community structure in relation to environmental characteristics has been studied in this ecosystem subject to intense anthropogenic pressures, particularly agro -industrial. Sampling was conducted monthly from April 2012 to March 2013 using a handled net and lobster pots. Eleven species of shrimp including three species (Macrobrachium equidens, M. zariquieyi and Melicertus kerathurus) adding to the list of shrimp fauna of Côte d'Ivoire were sampled during this study. Redundancy analysis (RDA) showed that environmental variables such as dissolved oxygen, conductivity, water temperature, transparency, plant debris and aquatic plants strongly diversity and abundance of shrimp fauna. This study has demonstrated the exceptional nature of this lagoon complex, and strongly recommends its preservation.
