BULLETIN OF THE BUREAU OF FISHERIES 
Investigators on the Pacific coast have found that the species feed on every 
marine form common to the San Francisco Bay region. 9 The food included the 
Pacific herring, silver salmon, steelhead trout, shad, carp, and perch; such crustaceans 
as Gammarus and Neomysis, and even Velella, the Portuguese man-of-war. It has

been observed that striped bass feed heaviest in the warm months of the year and in 
salt water. 
Nearly every type of angling bait can be successfully used to hook striped bass. 
Eel tails, and silvery trolling lures resembling fishes, are particularly effective. 
MOVEMENTS 
The movements of striped bass can be broadly classed as coastal, seasonal, and 
spawning. The exact nature and intensity of these movements are probably deter- 
mined largely by the character of the environment. That coastal movements occur 
is clearly indicated by the geographic range of the species along the Pacific and Atlantic 
coasts of the United States. Along the Pacific coast the striped bass has spread from 
the initial stocking in San Francisco Bay over a coastal range of about 850 miles. 
Self-sustaining colonies of striped bass are known to exist in San Francisco Bay and 
« Various writers on the food of striped bass are Ayres (1842), Verrill (1873), Rice (1883), Scofield (1931), Shapovalov (1936), and 
Merriman (1937).
