A comparison of the protein values in the two tables shows that 

 even under the old processing methods shrimp meal had a ;;lightly lower 

 protein content than meal prepared from other species. With the increased 

 use of the new machinery in shrimp processing establishiuents the quality 

 disadvantage of shrimp meal has become much more pronounced. 



Prices (quoted on the basis of protein content) of shrimp meal 

 are consistently below those obtaining for fish meal because of the quality 

 differential. Recent quotations for shrimp meal at the cannery have been 

 in the neighborhood of $60 per ton. At this price many canners, Tlie Bureau 

 of Business and Economic Research of the University of Miami reports, felt 

 that the effort expended in readying the meal for the market exceeded the 

 revenue derived from its sale. 



During the 1930' s there was an appreciable export trade with 

 some of the vjestern European countries in dried shrimp heads and hulls 

 for subsequent grinding into meal for animal and poultry feeds. A part 

 of the domestic production of shrimp meal was also exported to these 

 countries. Tliis market \ras lost during the war and has not been regained. 



The lack of uniform standards for grade and quality appears to 

 be another deterrent to an expanding market for shrimp meal. Fish meal 

 and oil are the primary products of the herring fishery of Alaska and the 

 menl\adon fishery of the Atlantic and Gulf States. Shrimp meal, on the
