I find there’s more action at dawn and dusk. But fishing by a permanent light (dock or street lights that are on every night) can be productive as the fish are attracted to the food that the light attracts, and they are use to the light being there. But in general, the brighter the moon, the more the fish may feed throughout the night. I read that the bigger browns are more active at night, but I guess haven’t tried often enough to hook into one yet. However, I’m in the North east so that may be completely different in your waters.
