Solunar Theory
Up Fish in Time Solunar Theory

History 

For more than 1000 years, those people whose lives have been dependant on primary industries for their livelihood have observed the behavioural cycles of marine life, plants and animals and established a direct link with the cycles of the moon.

In 1926, a man named John Alden Knight* compiled a list of 33 factors which influence or control day-to-day behaviour of fish.

One by one the factors were examined and rejected. Three of them merited further examination. They were sun, moon and tides.

When the original research was being done only the approximate time of moon up - moon down were considered. It became evident, however, that there were also intermediate periods of activity that occurred midway between the two major periods.

It was therefore identified that four periods of fish feeding activity occur in a single lunar day. The more evident periods were called MAJOR PERIODS and the two intermediate periods, shorter in length, were called MINOR PERIODS.

MAJOR PERIODS occur when the moon is in its upper or lower transits - Moon Above ( when it is above the observer’s head ) or Moon Below ( when it is on the other side of the Earth – beneath his feet ).

MINOR PERIODS occur when the moon is roughly half way between its upper and lower transits.

To prove the Solunar Theory, John Alden Knight examined approximately 200 fish catches. Over 90 percent were made during the New Moon when the effects of the Solunar Periods appear to be greatest, and, more important, they were made during the actual times of the Solunar Periods.

In another experiment, American biologist Frank Brown, had some oysters shipped from the Connecticut coast shipped to a tank in his laboratory in Evanston, Illinois, more than 1000 kilometres inland. After 14 days, the oysters, which normally open their shells at high tide, changed their daily rhythm to coincide with the Moon’s upper and lower transits over Evanston – the equivalent of local “high tide” had Evanston been a coastal city.

There are many instances and experiments regarding Solunar theory. I suggest you read various articles and publications regarding Solunar theory to gain a better understanding of the subject.

The sun and moon are the two major sources of external gravitational forces that affect the Earth and all its forms of life. The closer they are to you, the stronger the influence. The days of a NEW or FULL MOON provide the strongest influence in each month.

When a Solunar Period falls within 30 minutes to an hour of sunrise or sunset you can expect good fishing.

When you have a moonrise or moonset during that period the fishing will be even better.

When the above times occur during a NEW or FULL MOON, you can expect the best fishing action of the month.

LENGTH OF PERIODS solunar theory moon fishing  phase solunar theory 
Fish do not feed all the time. Fish often tend to go on the bite during a Solunar Period. If the weather conditions are favorable the fish will be active for one to two hours. During Minor times, fish feeding will be over a shorter period but feeding can be much more frenzied.

BEST FISHING DAYS 

These are the Major or Minor Solunar Periods that fall near the times of Sunrise or Sunset during a Full or New Moon. It has been documented that fish will bite on anything they see or smell when this condition exists.

A change in the weather coinciding with the periods may further enhance the activity.

WEATHER 

The weather plays a significant role as to the effectiveness of a Solunar Period. Adverse temperature, abnormal water conditions , barometric fluctuations, particularly when the trend is down, will offset the effects of Solunar Periods.

The Solunar Period’s influence will vary in intensity according to the position
of the moon. The times of new moon and when there is no moon in the sky, is the time of maximum intensity.

After the New Moon, fish feeding will be at maximum activity for about three days. Thereafter the degree of intensity tapers off until five days before the Full Moon where the activity will increase for around seven days.

There is one day each on which there is no moonrise. This occurs because the moon’s average period between two rises and sets is approximately 24 hours and 50 minutes. Therefore there will always be a day on which a moonrise (and a Solunar Time) will not fit.

CONCLUSION  solunar theory moon fishing  phase solunar theory moon phase solunar th
Remember that if there are no fish present, you will not be successful. Local knowledge of where fish congregate is vital. Plan your day so that you are where the fish are most likely to be during the Solunar Periods.

The Solunar Theory will predict the best day and time that each month has to offer, but is not a guarantee of any type.
