And yes, day and night fishes. Well, there was 4 times, 4x6 hours.
0-6 : no chances.
6-12 : tiny chances
12-18 : increased chances
18-0 : tiny chances.
Well, this was designed a bit more complicated. As IRL (I guess), there was a time for fishes to come, it was within the hour before or something that you could begins to get the fish. But I've read that there were this huge time lapse. So it need further investigations. I don't really remember.
