"They see a duck; bang, bang, bang and they don't see what is [beyond the duck]
"The ducks might be 50m away but the shot can go another 100 or 200m."
Otago Fish and Game officer Cliff Halford told the Otago Daily Times yesterday shooting from drifting boats was a long-standing and legal practice on the Clutha River between lakes Wanaka and Dunstan.
But with improved public access to the river, including new cycle tracks, it was "becoming a bit more difficult".
"It's just unfortunate sometimes historical users [such as duck shooters] can get shoved out of the way. It is really quite disappointing."
He knew of no incidents of anyone being injured through that form of hunting. He considered it was up to individual duck shooters to be responsible firearms users "knowing there could be anglers on the river, or walkers or bikers".
