Shorty - sorry I missed your question. At the rates below the SMB would be on the nest for a couple weeks. Some of the lit. has spawning occurring for several mths depending on conditions. You have a guess as to the factors resulting in a large spawn ?
RELATION OF TEMPERATURE TO SURVIVAL AND
INCUBATION OF THE EGGS OF SMALLMOUTH BASS
(MICROPTERUS DOLOMIEU)
DWIGHT A. WEBSTER
The mean incubation periods are given below, those for 1945 being
marked with an asterisk:
Temperature (�F.) ...................... 77 � 75 71 � 70 67 � 65 60 59 � 55 � 55
Incubation period (hours) ........ ,�2 54 70 78 90 98 150 167 238 234
Thus the incubation period at a constant temperature of 75 F is
about 2 1/4 days, whereas at 55 F it is between 9 1/2 and 10 days.
Incubation periods reported in the literature which have come to
the writer's attention are given in Table 1. The discrepancy between
these data and those currently presented is no doubt due in large part
to nocturnal-diurnal temperature fluctuations in natural waters.
