They were probably still there. You just didn’t catch them quite as hungry. If I fish all day, they will bite way better either late, midday or early, same time everyday. But the time will change as the week progresses. Can’t make the bite line up with the moon position but it seems to be connected
I've got some reefs made up I'm gonna dump today at the river. Been making them out of smooth bamboo in concrete. They hold fish and I don't lose hooks. Plan on dumping about 25 between now and end of next week.
