this is interesting as i too had the same issue in Europe i went to some lake that everyone talks about good fishing but hell all day long these small fish were biting , i mean as soon as the bait hits the water they bite its so frustrating. I thought it was maybe the wrong time of the year but there were so many of them i could not understand it.. the one guy said fish like to be in numbers so when a place is over fished the larger fish send out signals to start breeding in numbers and that is what causes the sudden burst of small fish being hatched... sounds weird but cud be true..
