That nibble very unpredictable, know of any angler. Short duration and very poor predictability of the bite, as well known to many. But in these conditions to plan a trip on a fishing trip, when to take vacation? This tried to answer the question in 1926, biologist Alden Knight (John Alden Knight). Studying the catches of fishermen in Florida, especially if caught big trophy fish, he noticed that the variability in the catches has some regularity, recurrence. Considering the various influencing factors such as weather conditions, it is gradually pushed most of them as unpredictable and chaotic, and came to a final conclusion – Catch affect the sun and moon. In the future, were conducted special experiments in the Oceanarium Chicago, where we studied the effect of moon phases on the activity of various underwater organisms. As a result, the work carried out by fully confirmed the hypothesis Knight. Since this theory called solunar or solar-lunar theory.
She argues that the disposition of two luminaries in some way affects all living oraganizmy living on our planet. In particular, the fish were active only in short periods of time. In these moments should expect an intense bite. Rest of the time the fish is behaving very passively and almost did not eat, can not but affect the Kleve. In our days, starting from the solar-lunar theory, and with increasing computational power, it became possible to build a fairly accurate prediction of biting a year in advance – Calendar angler. They are very easy to use for planning long fishing expeditions.
