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?
Discovering the little moon also reinforces the theory that most dwarf planets have moons.
Now of course this doesn't mean that you shouldn't let go of something during the waxing moon, or that you can't sign up for something new in the Waning moon. It does mean that if you have plans for this kind of work, including the tidal pull of the different moon phases in your plan, will support your actions in the same way that swimming with or against the tide makes your swim easier or more difficult.
