The Fish & Game event attracted more than 200 entries, but Malachi was one of the fortunate few at the morning session.
While the Brighton boy showed prowess at reeling in the catch, he was less keen on touching it afterwards.
Otago Fish & Game Council field officer Steven Dixon said while the fish were not biting that morning, it was a great family day which got children off the couch.
What was not caught at the weekend will likely be snapped up by anglers today at the start of the fishing season.
