MMNS Ichthyology Research

Ichthyology research at MMNS focuses primarily on the status, general ecology and taxonomy of the fishes found within Mississippi. Information on these basic elements provides the necessary framework to direct conservation strategies and assist with management decisions.  Much of our research is directed towards baseline sampling and general survey work. Target specific research projects are often dictated from the results of previous baseline studies, which note the need for additional information on the species. Research activities are conducted by MMNS Staff or guided collaboratively with personnel from other state and federal agencies. Material stemming from MMNS based-research is often integrated within the MMNS Ichthyology Collection.
