SHRIMP: HANDLING, TRANSPORTATION, AND USES. if 
and as arelish. Potted tuna fish, smoked salmon paste, and similar ~ 
preparations of halibut have recently met with some sale in this 
country. It is believed that a somewhat similar by-product can be 
made profitably from broken or small shrimp or from surplus stock 
taken in periods of slack markets. 
FOOD VALUE OF SHRIMP MEAT. 
Chemical analysis shows that shrimp are a nitrogenous food con- 
taining constituents similar to those found in cheese, meat, oysters, 
and eggs. Almost all of the edible portion of raw shrimp is protein, 
the muscle and tissue building food element. Simce shrimp are a 
concentrated nitrogenous food they may be used as the principal dish 
of a meal as well as the basis of a salad or as an appetizer or relish. 
Table 2, which shows the results of analyses of shrimp obtained 
from different localities and prepared in various ways, gives compari- 
sons between shrimp and other foodstuffs of a nitrogenous nature.

UTILIZATION OF SHRIMP WASTE. 
~When shrimp are headed about 43 per cent of their weight is thrown 
away. Small amounts of this material are used locally by farmers, 
who report that it has excellent fertilizing value for certain crops. 
As a thousand barrels of shrimp (50,000 to 60,000 pounds) are landed 
sometimes in a single day it is obvious that a large amount of poten- 
tially valuable fertilizing material is obtained fon the heading of 
shrimp. Some attention has been given to the drying of shrimp 
heads for sale as fertilizer. Experiments indicate, however, that in 
the process of drying a large amount of nitrogen is lost in the form 
of ammonia or other volatile substances. To retain this nitrogen it 
would seem advisable to mix the material before drying with a suit- 
able acid-reacting substance of value as a fertilizer. The material
