I have yet to find a scientific treatise that substantiates the influence of the sun or moon

on bass spawning. With regard to the timing of the spawn, 'photoperiod' displays a greater influence

than lunar phase or water temperature. In the vegetable kingdom as well,

‘photoperiod’ is the event trigger, while air temps and water temps are just coincidental indicators.

 

Shaw Grigsby & Peter Thliveros earned a living in Florida by catching bedding bass.

Based only on calendar period (day-length), they've taken bedding bass during all moon phases

and in water temperatures in the 50s.  To appreciate that feat, some years in central Florida (e.g. this year)

the water temperature never reaches the 50s. Furthermore, temperature changes that occur

during the actual spawn are generally well-tolerated by spawning bass, unless of course

they exceed deadly extremes.  From all appearances, 'high winds' are more damaging to spawning success than water temperature change, and windblown bedding flats appear to be

the major cause of missing year-classes.

I believe full moon & the spawn is just coincidental; a length of time.

 

Like water temperature the wide range of tolerable temperatures appears to be low 50s to upper 60s.

 

This wide range of acceptable "parameters" insures a healthy spawn.
