What is better for fishing, a high tide or a low tide? New moon or full moon? Each fisherman has his own theory in this regard but the majorities accept the influence of the moon as a factor to be taken into account.

Apart from the moon, neither do we discover anything new if we state that the dawn and sunset are also moments of great importance for fishing. But in reality this is not always the case. It is not difficult to find a fishing table on the internet or a specialist magazine, and for the most part rarely would we find a consistent and accurate relationship between such points of reference.

So what is the best day for fishing?
The answer is simple: too many factors come into play to be able to provide a reliable theory in this regard.

For example:

• If the temperature of the water is too cold normally the fish will appear lethargic.
• Neither can we enjoy good fishing if the atmospheric pressures showing on our barometer plummet.
Although yes, undoubtedly we have all fished well with a new moon or a full moon, and in the final count perhaps we can deduce that on such days we have obtained the best results.

However, all fishermen are aware of how variable our luck can be. And this is probably one of the disheartening factors for some, although for the true enthusiasts this just encourages us to continue trying. Fishing that is too easy would quickly become boring.

Each new fishing season the fish in our waters diminish. The decade in which we went fishing with our fathers and brought home a bucket full of fish is long gone. Currently, fish are much less plentiful and on occasion we might return home with empty hands. But let’s not get too disheartened yet… Suddenly, one day, and without any apparent explanation, the tip of our rod started to twitch time and time again, while fish of all species began to avidly bite, gobbling up practically everything we offered them. After a time, the same way it all began, the activity of the fish vanished completely and the waters returned to their earlier calm.

These periods we have all experienced in our long fishing careers, during which suddenly the activity of fish increases markedly, are called solunar periods and they form the basis of the solunar theory

SOLUNAR THEORY

The solunar theory was initially proposed by the American John Alden Knight in 1926 and has been supported by the systematic analyses of scientists and biologists in subsequent years. It is based on experimental incidents from which it can be deduced that the action of the sun and the moon influences the activity of all living beings in nature. The times of day in which living beings show greater activity are the so-called solunar periods.

We can distinguish two types of solunar periods:

– Major periods: have approximately 2 hours duration although on certain occasions they may exceed 3 hours. They begin the moment of the lunar transit (when the moon is overhead) and the opposing lunar transit (when the moon is under our feet). Normally these are the moments of greatest fish activity during each day. The most fervent supporters of this theory state that there is not one species of sport fish that cannot be found eating during a major Solunar Period.

– Minor periods: are intermediate periods of lesser duration (approximately 1 hour) which coincide with the rising and the setting of the moon. During these periods there is also an increase in fish activity in relation to the rest of the day. The solunar periods appear 4 times every lunar day.

Remember that a lunar day lasts 24 hours and 50 minutes approximately, so normally within the same day (24h) we will find 2 Major Periods and two Minor Periods.
