If you have ever had a great sea-trout session, and seen plenty of them jumping for long periods and could not figure out why? Maybe you can put it down to the solunar theory. In short the theory was realized by John Alden Knight back in 1926, he seen patterns emerging on fish activity, so he studied the results of 200 catches with 33 possible influences, he narrowed it down to 3, tides,moon phase, and sunrise/sunset. Tides + moon have long been associated with fish activity but knight made the connection between the moon being directly overhead/underfoot and peak activity during peak solunar periods, he called these “major periods”, and the times around moon rise/moon set where there was less activity he called these “minor periods”. He noted that if sunrise/sunset coincided within 30-60 minutes a “major period” during a peak solunar period eg full +new moons you will have great fishing , especially on new moons,of course you will still need to have all your local factors in place during the “major periods” to experience spectacular fishing.
I first experienced this back in the early 90’s , long periods of taking, followed by longer periods of trout jumping, I noted it at the time but it was not until a couple of years later I stumbled on knights solunar theory and the pieces of the puzzle fell into place , since then I experienced it maybe 12-14 times and had spectacular fishing every time, leading me to strongly believe that the sea-trout is well tuned into the solunar theory.
