The correct answer to this open question is the following.
As there are no pictures of the four days, we can say that the best days for fishing are the ones when the moon is closest to the Earth and the tides are running. This moment happens when the tide is in the middle period. Not in the high or low levels of the tide, but in the middle. So a moving time is a perfect moment for fishing and getting good catches.
The answer is when the moon is closest to the earth.
The image shows the two days John will get the best catch.
I hope this helps! :)
