received 25 cents per dozen. The number of 

 whole shrimp per pound varied from 17 to 37 

 (table 3). The tail (abdomen) weight ac- 

 counted for 51 to 53 percent of the body weight, 

 and the recovery of cooked and shucked tail 

 meat was 21 percent of the body weight. The 

 cost per pound of whole shrimp when pur- 

 chased by the dozen varied from 55 to 64 cents. 

 The price of shucked, cooked tail meats to the 

 consumer, at 25 cents per dozen live shrimp, 

 varied from $2.63 to $3.01 per pound in June. 

 The value of the shrimp fishery in the lower 

 St. Paul River was estimated. I was not able 

 to gather total catch statistics because of the 

 erratic method of marketing and the varying 

 number of fishermen and traps fished. In 



July 1952, 12 fishermen were known to be 

 shrimp fishing in the lower St. Paul; conserva- 

 tive estimates were that 16 additional fisher- 

 men participated. The entire catch by 4 fish- 

 ermen in July was 481 dozen shrimp, worth 

 $120.25. If their catches can be considered 

 average, the estimated catch in July by the 28 

 fishermen was 3,367 dozen, worth $841.75. Be- 

 cause I considered July to be an average month, 

 the value of the fishery during the 9-month 

 fishing season probably exceeded $7,500.
