FISHERY INDUSTRIES OF THE UNITED STATES, 1938 219 
in value as compared with 1935, when the first preceding survey of 
the total catch was made. Available data for both 1936 and 1937 
show that the production .of frozen fish in these States declined in 
1937, while the catch of shad in the Hudson River was the largest on 
record since 1901. 
Chesapeake Bay States—In 1936 the catch of fishery products in 
the Chesapeake Bay States decreased: in both volume and value, 
as compared with the previous year. The value of menhaden prod- 
ucts, which were produced in Virginia, declined during the year, 
while both the quantity and value of fresh-shucked oysters, and 
packaged fresh-cooked crab meat increased. 
South Atlantic and Gulf States —The catch of fishery products in 
the South Atlantic and Gulf States during 1937 declined in volume 
but increased in value, as compared with the previous year. There 
was a large increase in the value of manufactured fishery products 
produced in these States in 1937 due to material increases in the pro- 
duction of packaged fresh-cooked crab meat, fresh-shucked oysters, 
and canned shrimp and oysters. 
Pacific Coast States —The commercial catch of fishery products in 
these States during 1937 decreased in volume, but increased in value. 
The decrease in volume resulted principally from reduced catches of 
pilchards in California. The 1937 production of canned sardines, 
salmon, and tuna increased as compared with 1936, while the packs 
of mackerel and oysters decreased. The value of fishery byproducts, 
which consist largely of fish meal and oil also declined. 
Lake States —In 1937 the commercial catch of fishery products in 
the Lake States decreased in both volume and value, as compared with 
1936. The decreases resulted principally from reduced catches of 
blue pike. 
Mississippi River and tributaries —The most recent complete statis- 
tics of the catch of the Mississippi River and tributaries are those 
collected for 1931. As compared with 1922, when the most recent 
preceding survey was made, there was a decrease in the catch. This 
decrease was reflected principally in a smaller catch of fresh-water 
mussels. A survey made for Lakes Pepin and Keokuk, and the 
Mississippi River between these two lakes, for 1937 showed a decrease 
in the catch of fishery products in Lake Pepin and the Mississippi 
River between these lakes, but an increase in the catch in Lake Keokuk 
as compared with the previous year. The production of fresh-water 
mussel-shell buttons declined in 1937 as compared with 1936. 
Alaska.—The catch of fishery products in Alaska in 1937 decreased 
in volume but increased in value, as compared with 1936. There was 
« material decline in the yield of salmon for the year, while the catches 
of herring and crabs increased. The production of frozen fishery 
products and byproducts increased in quantity and value in 1937, 
while the output of fresh, cured, and canned products decreased.
