Moon Phases and Fishing: A Complete Lunar Calendar Guide

The Moon and Fish

The relationship between the moon and fishing goes back thousands of years. Modern science confirms that the moon's gravitational pull affects not only tides but also feeding behavior of freshwater fish.

The 4 Main Phases

New Moon — EXCELLENT (10/10)

The moon and sun are on the same side of the Earth. Combined gravitational pull is at maximum.

• Fish feed aggressively throughout the day
• Major solunar periods are longer and more intense
• Best phase for trophy bass
• Dark nights mean fish are hungry at dawn

Full Moon — VERY GOOD (9/10)

The moon is opposite the sun. Strong gravitational pull.

• Excellent activity, especially at dawn
• Fish may feed at night, so morning activity can start later

First Quarter — FAIR (5/10)

The moon forms a 90° angle with the sun. Reduced gravitational pull.

• Moderate activity, dependent on weather and pressure
• Compensate with good technique and location

Last Quarter — FAIR (5/10)

Similar dynamics to first quarter.
