Fish Ecology and Fisheries

Louisiana has nearly 400 miles of coastline and thousands of miles of rivers and streams. At LSU’s College of the Coast & Environment (CC&E) researchers and students are working to study and enhance the quality of fisheries in Louisiana, as well as across the United States and internationally. Improved water quality and wetland conditions in fisheries help both the environment and the associated local economy – as fishing and ecotourism activities are vital to the state’s economy.

Natural processes and human factors influence the health of our fisheries, and CC&E researchers are studying these influencing factors, learning ways to better measure changes and assist with recovery following disrupting events. CC&E uses the results of this work to directly inform public policy and educate local stakeholders, who then use this information to adjust their own practices as necessary.

Scientists at CC&E research a large range of issues related to fish ecology and fisheries, including food web dynamics; harmful algal blooms; red tide kills; water quality; ecosystem services; environmental economics; abundance, growth and transport of lavae and juveniles; quantitative relationships of fish to habitats; mangrove ecosystems; productivity; biogeochemistry; nutrient regeneration of coastal ecosystems; and contaminant effects. Commercial and recreational fishing and seafood harvesting are essential jobs in Louisiana that directly provide a positive impact on local communities, the state of Louisiana, and throughout the United States, as our prized seafood is shipped across the country. Fisheries assessment and management is essential to monitor and improve our aquatic ecosystems, and our researchers at LSU are advancing knowledge in this industry.
