AfiSTRACT 



MORE SHRIMP ARE MARKETED IN THE FROZEN FORM THAU IfJ ALL OTHER FORMS 

 COMBINED. PACKAGED HEADLESS SHRIMP RANKS FIRST IN POPULARITY. OTHER 

 PRODUCTS COMMONLY SOLD FROZEN ARE RAW PEELED AND DEVEINED, COOKED AND 

 PEELED, AND COOKED AND UNCOOKED BREADED, SHRIMP.' FRESH SHRIMP ARE 

 PREFERRED IN SOME MARKETS, NOTAFJLY IN NEW YORK CITY. CANNED SHI?IMP 

 WITH THE EXCEPTION OF THE WAR YEARS WHEN THE SIZE OF THE PACK WAS 

 AFFECTED BY THE TIN SHORTAGE, HAVE RETAINED THEIR MARKET; DRIED SHRIMP 

 PRODUCTION HAS DECLINED A3 THE RESULT OF THE LOSS OF ITS PRINCIPAL 

 EXPORT MARKET. 



IN 1956 THE VALUE OF MANUFACTURED SilRIMP PRODUCTS AT THE 

 PROCESSOR'S LEVEL WAS $109.5 MILLION. FRuIEN P.XI'.AGED PRODUC 1 S ACCOUNTED 

 FOR 83 PERCENT, AND CANNED PRODUCTS FOR 15 PERCENT, OF TIMS TOTAL. 

 THE REMAINING TWO PERCENT WAS DRIED AND OTHER Ml SCELLAllLUUS SHRIMP 

 PRODUCTS. 



FRESH SHRIMP PLANTS, IN GENERAL, ARE VERY SIMPLE ESTABLISH- 

 MENTS. SOME ESTABLISHMENTS ONLY FREEZE SHRIMP BUT THE MAJORITY PROCESS 

 A VARIETY OF OTHER FISHERY AND NON-FISHERY ITEMS IN ADDITION TO SHRIMP. 

 SHRIMP CANNERS AND BREADERS, USUALLY, ARE MORE SPECIALIZED THAN SHRIMP 

 FREEZERS. THERE ARE A NUMBER OF PLANTS WHICH ALSO PROCESS COMPLEMENTARY 

 PRODUCTS, SUCH AS OYSTERS AND CRABS. 



THE DEGREE OF MECHANIZATION IN THE PLANTS IS SMALL; EVEN IN 

 THE MOST HIGHLY MECHANIZED SEGMENT OF THE INDUSTRY, I.E. CANNING, MOST 

 OPERATIONS ARE STILL PERFORMED BY MANUAL LABOR. A STUDY OF THE FLOW 

 OF OPERATIONS IN A SAMPLE OF PROCESSING ESTABLISHMENTS INDICATES THAT 

 THERE IS OPPORTUNITY FOR IMPROVING PLANT LAY-OUT AND MANUFACTURING 

 PROCEDURES. 



PRODUCTION COST DATA WERE OBTAINED IN THE COURSE OF ANOTHER 

 STUDY FOR A SMALL SAMPLE OF PROCESSORS. RAW SHRIMP COSTS AVERAGED 

 ABOUT THREE FIFTHS OF TOTAL COSTS IN BOTH BREADING AND CANNING PLANTS. 

 IN ESTABLISHMENTS PRODUCING ONLY PACKAGED FROZEN SHRIMP, THE PROPORTION 

 OF TOTAL COST REPRESENTED BY RAW MATERIAL WAS SUBSTANTIALLY HIGHER. 



A SECONDARY USE OF SHRIMP IS FOR BAIT BY SPORTS FISHERMEN. 

 MODIFICATIONS OF THE OTTER AND BEAM TRAWL CALLED FRAME AND PIPE TRAWLS, 

 AS WELL AS CHANNEL OR LIFT, CAST, PUSH, DIP AND BRIDGE NETS ARE AMONG 

 THE EQUIPMENT ENCOUNTERED IN THIS FISHERY. 



A SMALL SHRIMP WASTE INDUSTRY CONFINED TO LOUISIANA AND THE 

 CAROLINAS IS HANDICAPPED BY COMPETITION FROM OTHER FISHERY BY-PRODUCTS 

 RICHER IN PROTEIN. SHRIMP MEAL IS USED AS AN ANIMAL FEED SUPPLEMENT.
