The moon has long been believed to have an influence on various aspects of our lives, including the natural world. One area where this influence is often discussed is in fishing. Many anglers and fishing enthusiasts believe that the moon plays a significant role in determining the success of their fishing trips. In this article, we will explore the various ways in which the moon can affect fishing and examine the scientific evidence behind these claims.

Tidal Movements

One of the most well-known ways in which the moon affects fishing is through its influence on tidal movements. The gravitational pull of the moon causes tides to rise and fall, and these tidal movements can have a direct impact on fish behavior. During high tide, fish are often more active and tend to move closer to the shore, making it easier for anglers to catch them. Conversely, during low tide, fish may retreat to deeper waters, making them more challenging to catch.

Moon Phases

Another aspect of the moon that is often considered in relation to fishing is its different phases. The moon goes through a regular cycle of phases, from new moon to full moon and back again. Some anglers believe that certain moon phases are more favorable for fishing than others. For example, it is commonly believed that fishing during a full moon can be less productive, as the bright moonlight can make fish more cautious and less likely to bite. On the other hand, fishing during a new moon or a crescent moon is often thought to be more successful, as the darker skies provide better cover for anglers and make fish more active.

Solunar Theory

The concept of solunar theory is often associated with the moon’s influence on fishing. Solunar theory suggests that the gravitational forces exerted by the moon and the sun can affect the feeding patterns of fish. According to this theory, fish are more likely to feed during specific periods of the day when these gravitational forces are at their peak. These periods, known as “major” and “minor” feeding times, are believed to occur when the moon is directly overhead or underfoot. Many fishing enthusiasts use solunar tables, which provide predictions for these feeding times based on the moon’s position, to plan their fishing trips.

Scientific Evidence

While many anglers swear by the moon’s influence on fishing, scientific evidence on the topic is somewhat limited. Some studies have suggested that moon phases and tidal movements can indeed impact fish behavior and feeding patterns. For example, a study published in the journal Fisheries Research found that fish catch rates were higher during specific moon phases, with the new moon and the first quarter moon showing the most significant increases. However, other studies have failed to find a consistent correlation between the moon and fishing success.

It is important to note that factors such as weather conditions, water temperature, and the availability of food also play crucial roles in fish behavior and fishing success. Therefore, while the moon may have some influence, it is just one of many factors to consider when planning a fishing trip.


In conclusion, the moon can indeed affect fishing through its influence on tidal movements, moon phases, and the concept of solunar theory. While the scientific evidence on the topic is not conclusive, many anglers continue to believe in the moon’s impact on fishing success. Whether it is due to the increased activity during high tide, the darker skies during certain moon phases, or the gravitational forces affecting fish feeding patterns, the moon remains an intriguing factor to consider when planning a fishing trip.
