Matt caught the carp, known as the Rhino, at Darrow Farm Fishery near Diss. Will Farrer, who runs the fishery, said that the fish is definitely one to watch. This carp has also come on leaps and bounds since it was first introduced to the lake. When it was placed into the lake, the fish weighed just 11lb but has grown significantly in seven years. "Good fishery management, allowing the fish to have a break on days with strict rules on bait, has led to the fish growing quickly."
