BULLETIN OF THE BUREAU OF FISHERIES 
SEASON OF 1934 
This was a relatively poor seed year in this bay, as may be seen in table 30 and 
figure 31. Even for the dike B results it was necessary to employ a scale 10 times as 
great as that used in most of the figures in order to obtain a satisfactory graph. After 
starting to set on about June 16 the larvae never attached in great numbers, so that 
at the time of the maximum the bags of shells caught an average of only about 300 
spat per day in dike B and only about 50 per day in dike E. The entire setting period

occupied only about 1 month, and no larvae became attached after the middle of 
July, although bags of clean shells were planted twice weekly until the end of 
September.

SEASON OF 1935 
Because of more concentrated investigations in Oyster Bay little attention was 
paid in 1935 to Mud Bay. One series of bags of shells ivas completed in dike E, which 
is not good seed ground. The catch in dike B, judging from records of previous years, 
was probably at least five times as great. The trend of the setting season is shown 
in table 31 and figure 32. Setting started at the last of June, reached a maximum at 
the middle of July, and stopped at the first of August. Even during the time of most
