And that's where UNC Sea Grant projects can help management agen- cies like DMF. During 1979 and 1980, George Fishman, a researcher in the Curriculum in Operations Research and Systems Analysis at the Univer- sity of North Carolina at Chapel Hill, developed a computer model that will evaluate alternative management policies for the shrimp fishery. Plugged into the model are the biological features of shrimp such as migration habits, mortality rates, distribution in the estuaries, length-weight relationships. The model also takes into account characteristics of the shrimp fishery—number of fishermen shrimping, the intensity of their shrim- ping efforts. Finally the model figures in the price structure of the fishery which varies according to the season and availability. Using this model the North Carolina Division of Marine Fisheries, or a fisheries management agency in another state, can plug in different management schemes to see which works best. A management agency may want a policy that provides the most profit per unit of effort by the fishermen. Or perhaps they want a scheme that would result in greater pounds landed. Whatever the needed results, the model can test proposed and present policies to see how they stack up against one another. Another model for fishery manage- ment that will include some work with shrimp is being developed now by Sea Grant researchers Jim Easley, Thomas Johnson and Frank Benford, all of North Carolina State University. They will be setting up a model to con- sider individual problems within fisheries—for example, the impact of fuel costs, market effects—and to con- sider problems that arise as seasons for various fish overlap. Easley, along with two other researchers, conducted an earlier study that took a
