Solunar Theory
If you’re a fishing enthusiast but don’t seem to be having any luck, it might be time to start looking at the moon for guidance. Have you ever heard of the Solunar Theory? Originally develeoped by John Alden Knight in 1962, this theory suggests that the sun and moon influence fish behaviour, creating peak feeding times that can improve your chances of a great catch. But does it really work?
What is the Solunar Theory?
The theory is based on the idea that fish are more active during certain periods of the day, depending on the position of the moon and sun. Knight was able to identify major and minor feeding periods.
Major periods- When the moon is directly overhead or directly underfoot. These last about two hours and are considered to be the best times for fishing.
Minor periods- When the moon is rising or setting. These last around an hour and offer another period of increased activity.

Does it really work?
Many experienced anglers swear by solunar tables to predict the best fishing times. While not a guaranteed formula, there is logic behind the theory. The moon affects the tide so it’s easy to believe the moon affects the fish and their feeding habits.
While it can be a useful tool, it’s not the only thing that affects fish activity. Weather conditions, temperature, seasonal patterns and bait all play into your fishing success.
