To increase your fishing success you're going to want to concentrate you're fishing efforts at two specific times of the month. These times are the four day period that coincides with either a Full Moon or a New Moon. Using these two time frames will increase you chances of success tremendously. You will find that it is not only going to improve your success, but that the chance of catching larger fish is also greatly improved during these two phases of the Moon. If knowing this simple fact is going to improve your success why would you not at least give it a try?
A moon is defined as a natural satellite that orbits a larger body--such as a planet--that, in turn, orbits a star. The moon is kept in its position both by the gravity of the object that it circles, as well as by its own gravity. Some planets are orbited by moons; some are not. Some dwarf planets--such as Pluto--possess moons. In fact, one of Pluto's moons, named Charon, is almost half the size of Pluto itself, and some planetary scientists think that Charon is really a chunk of Pluto that was torn off in a disastrous collision with another object very long ago. In addition, some asteroids are also known to be orbited by very small moons.
Now, the fishing magazines and sites around the Internet will have you believe that the relationship between solar/lunar cycles and fishing is much more complex than I have explained here. In reality it's not. In fact, if you try to follow most of the charts out there, you will find no direct correlation between those charts and the number and size of fish you catch.
