PROGRAM DEVELOPMENT PROJECTS

The vast size, biological richness, and cultural diversity of Louisiana’s coastal region create unusual problems as well as research opportunities. Sea Grant development funds enable the program to address an environmental crisis, pursue an unanticipated research discovery, or expand an existing project outside of the two-year fiscal cycle. These opportunities to stimulate new research, education, or advisory activities strengthen Sea Grant’s impact on Louisiana’s coastal and marine environment. A partial list of current program development projects follows.

Intensive Propagation of Marine Finfish in Recirculating Systems: Improving Survival and Growout Efficiency During the Larval Stage
Chesney, E., LUMCON

Developing reliable and cost-effective methods of rearing larvae and producing fingerlings for rearing systems remains one of the greatest challenges to success in marine fish culture. Closed, recirculating systems technology is proving to be a viable approach for commercial fingerling production that offers some distinct advantages over pond production. However, additional research is needed to establish reliable, efficient and cost-effective methods for intensive larviculture. The project’s goal is to generate new knowledge for immediate use by members of the industry. The principal investigator is collaborating with two industry project partners on research that will improve marine fingerling production rates and efficiency. Specific research objectives are to reduce the reliance on live feeds for larviculture and shorten the larval stage duration by improving growth and survival rates in the larval stage of growout.

Development of Formulated Diets for Florida Pompano Trachinotus carolinus Aquaculture – Part II: Replacement of Fish Meal with Plant Proteins
Reigh, R., LSU – Agricultural Center

The replacement of fish meal with plant proteins in the manufacture of aquafeeds is of particular interest to fish nutritionists and producers because the global sources of fish used to produce meal are near maximum sustained yield and world prices remain high. This economic pressure is driving research with alternative feed ingredients in several countries, and it is possible that plant proteins derived from soybeans will eventually become the primary constituents of diets for pompano and several other farmed species. The challenge in finding substitute ingredients is two-fold: not only to reduce feed costs, but to do so while maintaining adequate levels of essential Omega-3 fatty acids to provide for the dietary requirements of the fish and ultimately, fish consumers. Florida pompano is regarded as an excellent candidate species for marine aquaculture in the future, and the results of this project may serve as a nutritional model for other marine species as well.

Review of Land Use Planning In Coastal Louisiana
Wilkins, J., LSU – Office of Sea Grant Development

Experience from recent hurricanes has underscored the point that any responsible course of action along the Louisiana coast, whether it is comprehensive coastal restoration or a strategic retreat, must recognize the need for land use planning and development control. The degree to which that control is possible and practiced, and its relationship to implementing coastal restoration activities and community protection, is crucial. Louisiana State University can assist parishes in developing the expertise and planning tools to facilitate strategies for siting or de-commissioning infrastructure, planning for coastal change and educating the public about risk management. The project’s objectives include assessing the current state of land use planning authority and practice as it pertains to the ability of the state and local governments to respond to coastal crises, and to provide coastal parish and state land use planners with information on legal and policy tools that will allow them to use available powers to achieve public safety goals and to optimize the effectiveness and value of coastal restoration projects. Where sufficient powers are lacking, the principal investigators will identify these gaps and provide information to land use planners allowing them to promote land use planning as a necessary element in addressing land loss issues. Additional objectives include providing lawmakers with information on land use planning that will assist them in enacting legislation necessary to respond to the requests and needs of land use planners for greater powers with which to address coastal land loss issues.
