And, they report, the hybrids are just as good to eat as the popular striped bass. Better tests Vibrio parahaemolyticus is the big name for one little bacterium that has microbiologists baffled. Through Sea Grant studies begun in 1978, NCSU food scientists Bibekananda Ray and Marvin Speck found that vibrio is the most prevalent bacterium in North Carolina seafoods. The researchers are skeptical about the ac- curacy of standard tests which show that most of the Vibrio parahae- molyticus are non-pathogenic. This year Ray will head a new project designed to formulate a simple, sen- sitive test which will distinguish be- tween the two strains. Management Last year's shrimp harvest of to million pounds was a "fair" catch after the worst harvest on record in 1978, million pounds. But the 1979 harvest was nothing like the catches of years past, which were often 4 million to 5 million pounds. Officials are hoping that better management policies can put the shrimp fishery back on an even keel. Researcher George Fishman of UNC- CH is developing a numercial model that will help management agencies predict the economic and biological ef- fects of differing shrimp management policies on shrimp and other fishes. The model will be based on the biology and behavior of shrimp as well as the geographic, social and economic aspects of the North Carolina fishery. Spot, croaker Another researcher, John Miller of NCSU, is also working toward better fishery management policies. Miller is studying juvenile spot and croaker in their estuary nurseries to see which seasonal, environmental and biological factors most affect their abundance. So far, Miller has found that both spot and croaker rely largely on zooplankton for food. Besides a com- mon diet, croacker and spot also seem to share h
