Then again, sometimes I pay attention. I know that the spring spawning activity of various freshwater bass and sunfish tends to peak around a full moon. And the moon, of course, affects the ocean tides. So when I'm going surfcasting, I'll look for the dates of a new moon when tides will be highest and the nights will be darkest. The bright light of a full moon, on the other hand, has often seemed to kill my night-fishing luck despite the corollary high tides.
