Fishing on the river. A catchy place One spring day I went out for another fishing trip. This time I went to a new place on the river. I found a catchy place near the canal that flows into the river. There is a current at the confluence and this very lures the fish at the mouth where the channel flows into the river. In such places where there is an influx of fresh water and various feeds and a lot of fish gather like white, roach bream rudd, crucian carp, it also attracts predatory fish in search of food.
