Yes. Striped bass have cones tuned to green and to orange, and their eyes respond well into the red. But it is a bright-light eye that retunes after dark, becoming about 40 times more sensitive and shifting toward blue-green. Whether they feed more at night has not been measured.

Sand lance feeding is maximal between 100 and 1,000 lux and nearly stops at 1. In the dark they are not swimming badly — they are fully buried in the seabed. Three lab papers from 1974 say so, and it changes what you should be throwing after dark.

Half the beach goes home when the surf turns to chocolate milk and the other half says that is exactly when to stay. The measurements are real — on smallmouth, largemouth, bluegill, sablefish and larval stripers — and they point to light, not mud, as the thing to watch.

Somebody tested popular solunar tables against real catch records and they failed to predict success. A separate study on a lake with no tides at all found the moon effect peaking at full AND new — which rules out both explanations usually offered. What survives is smaller, and more useful.

Two analyses from one Bay of Fundy tagging project looked for a tidal effect on striped bass. One found no depth difference between ebb and flood across over 9,000 detections; the other found detection independent of water level (p = 0.93). The same fish do move vertically, just on a different clock.
